Read all about it and the great details in … But even with all the advancements in safety we have on our modern automobiles, this would likely be a tough accident to walk away from. You have done again Paul. To put the nascent field of automotive aerodynamics in perspective, the typical two-box car of the twenties was more aerodynamic going backwards than forwards, as this ass-backwards DeSoto proved in tests. What If The Volkswagen Beetle Had A Front Engine. Paul, you’re one of my top favorite car guys. Favored especially by Luftwaffe brass, they had a nasty habit of killing them, due to its wickedly-abrupt oversteer, thanks to the combination of rear V8 and swing axles. Dirty Car” and you should be able to find the episode. That Airflow video was quite fascinating! The resemblance of the production KdF Wagen to Tjaarda’s 1934 prototype, especially certain details of the front end, seem like a bit too much of an accident. Either of these values put the “pillbug” at or near the top of the list of the most aerodynamic concept cars ever built, like the Ford Probe V of 1985, with a Cd of  0.137 (Full list here). It’s made in 1938, I can’t remember a design earlier than that, with fully integrated fenders all around. Paul, Its important to note that the rise of interest in aerodynamics in the 1930s arose out of the desire to reinvent the automobile from its horse and wagon origins and the assumptions that average driving speeds would be on the rise with modern roads. American Brands: AMC, Jeep and All Others, Tractors, Lawn Mowers, Off-Road Equipment, Automotive History: An Illustrated History Of Automotive Aerodynamics – Part 1 (1899 – 1939), http://www.thetruthaboutcars.com/2010/02/an-illustrated-history-of-automotive-aerodynamics-in-three-parts/, https://en.wikipedia.org/wiki/Aurel_Persu, Curbside Capsule: 1989 Chevrolet Caprice – Please Pass The Margarine. After he took over as chief design engineer at the Czech firm Tatra in 1921, he developed the basis of a series of remarkable Tatra cars and eventually streamliners with platform frames, independent suspensions and rear air-cooled engines that were profoundly influential, and essentially set the template of what came to be known as the “streamliner” and influenced cars around the globe for years to come. road car. When I started this article, I assumed it was the earlier one transplanted to CC.

To demonstrate just how rapidly and far the aerodynamic envelope was pushed in this golden decade of streamlining, this 1939 Schlörwagen prototype was tested originally at Cd 0.186, and a model of it was retested by VW in the seventies yielding a Cd of 0.15. Dreamers, engineers, racers and entrepreneurs were lured by the potential for the profound gains aerodynamics offered. The Zephyr had one, and it was a success, despite not being nearly as a good a car as the Airflow. There were 3 or 4 Tatras at the annual Rockville show held outside DC in October, in the 1993 show. Air is also considered a fluid in this case. The first Paul Jaray car looks very top-heavy – I think it would topple over if it went around a corner at any speed! Racers, particularly those chasing the coveted Land Speed Record (LSR), were generally the first to employ aerodynamic aids. Plenty of microcars, check. BTW, what was/is your handle at TTAC? Great article, Paul. That would not be bettered until 1924, and not until 2009 for steam powered vehicles. It seems that most of the early designers of aerodynamic cars understood this. Aviation engineer William B. Stout designed this extremely roomy mini-van precursor using  a unitized body structure and a rear Ford V8 engine. Aviation engineer William B. Stout designed this extremely roomy mini-van precursor using  a unitized body structure and a rear Ford V8 engine. Here are some clays from about 1933 or so, showing the development of both the smaller VW-like v570 on the right, and the larger streamliners in the rear. The Tatra is more attractive than the Porsche. Undoubtedly, the real breakthrough aerodynamic passenger car was the German Rumpler “Tropfenwagen” (teardrop car) of 1921. They virtually built a roll cage and tacked the panels on no wonder crashing it didnt do any damage race cars are built that way now. Citroen DS racing car, check. Learn how your comment data is processed. Let’s jump back to Czechoslovakia and the fertile Tatra design studios. Williams F1 - History of Aerodynamics. I know wings and radial engines clutter things up but still…. For some reason they don’t photograph very well. Of course, Americans’ introduction to streamlining had come two years earlier  in 1934, with the stunning Chrysler Airflow. As for the Airflow, it was my understanding that it was a “semi-unitized” construction that the engineers referred to as “bridge truss” construction. However, it was not like that when it first came into being. Anyway, it was a lot of fun and I wish I had this article available when I was teaching that. I appears to have  Isetta-type front doors for the front seat passengers. The first was built in 1932, and several more variations, a total of nine, were built in the mid thirties, but series production never got off the ground, due to an asking price almost four times higher than a Chrysler Imperial Airflow of the times. I love the “Tropfenwagen”. Due to the very heavy bodywork, it turned out to not improve on the top speed of the open Alfa it was based on. The La Jamais Contente (The Never Satisfied) was the first automobile to break the 100kmh (62 mph) record, in 1899. I love the streamlined cars of the 30’s, especially the Tatra. One of the first full width pontoon cars. The driver’s position seems to negate the aerodynamic aids, or maybe he was just posing, and more likely crouched down for the actual run. “Bil” is the Swedish name for “car”. Another one-off I’ve always liked, is the humorously named “Venus Bilo”. An introductory approach to define the principles of aerodynamics, which guide the technology of cars. I especially like the “Flying Hamburger” – a train in Germany! His early designs tended to be very tall, and with questionable proportions and space utilization (below). For those who don’t know or remember, here’s the link to the previous series, when Paul (and CC) were still at TTAC: http://www.thetruthaboutcars.com/2010/02/an-illustrated-history-of-automotive-aerodynamics-in-three-parts/. The buying public was perceived or conditioned to need change, and the rounded pontoon gave way to ever-more dramatic and flamboyant but aerodynamically blunt designs. Aerodynamics has played an important role in car racing since the late 1960s, when introduction of The history of automotive aerodynamics The first vehicle to break the 100km/h barrier was the Jamais Contente (Never Satisfied) and it was all-electric. You’re very welcome! Hungarian-born Paul Jaray used his experience working in the aeronautical field, especially designing Zeppelins, to develop a specific formula for automotive aerodynamic design principles that lead to a patent, applied for in 1922 and issued in 1927. http://img.photobucket.com/albums/v724/NeilBlanchard/Schlor-FrontView.jpg In 1983, the flat-bottom regulation came into force, which prohibited all aerodynamic aids that generated downforce on the underside of the cars. The Model 3, when tested, clocked a 0.21 drag coefficient. As this 1934 prototype for an American rear-engined sedan by John Tjaarda shows, the Europeans weren’t working alone. The failure of the Airflow probably comes down to one primary aspect: that overly flat waterfall grille. Anyone? Excitedly looking forwards to further (expanded) episodes. http://img.photobucket.com/albums/v724/NeilBlanchard/Schlr-SideProfile.jpg It also explains the journey of cars from its initial phases to modern supercars and how aerodynamics … Tatra won. Aerodynamics is a branch of dynamics concerned with the study of the motion of air. You’re familiar, but I can’t quite place you. But I think it’s strikingly beautiful, in some sort of Scandinavian art deco way. One of the things I love about aerodynamics is that little changes can make big differences too. I too look forward to the rest of the story. Enjoyed the English Burney ad saying: “slight wear on the tires”. In many (other) ways, the Tatra 87 was the Porsche Panamera of its time. Of all the cars, two stood out. But this had relatively more to do with style (and even affectation) than a genuine effort to push the envelope in terms of leading edge aerodynamics. A stunning achievement, the long-tailed T77 was powered by a rear air-cooled V8, and began a long series of Tatras until the 1980s along similar lines. The “Dymaxion” name brings to mind a gas analyzer I helped to develop some time ago, by the same name: http://www.ceb.uminho.pt/labs/reequip/MS_58305_64351.jpg Although the visual cues are not really as significant as they might appear to us now, because these were the leading-edge design elements of the time, and widely imitated or shared, on both side of the Atlantic. Great research on so many vehicles. It had a mid-engined W6 engine, and four wheel independent suspension using swing axles which Rumpler patented. •!The shape of a falling drop of water was considered to be aerodynamically perfect. And that’s because aerodynamics play a crucial role in determining the range of an electric car. Yet in the more recent cars it was discovered that this vortex is important to keep near the car as the front suspension opened up this area and “barge boards” became a … P.S. The first of these, the T77, arrived in 1934 (below): The T77 was measured to have a Cd of .212, a number that was not broken by a production car until GM’s EV-1 of 1995, which measured at .195. I love this stuff, too. An ironic ending for Rumpler, but his ideas spawned imitations and extensions world-wide, and opened the whole field. Either of these values put the “pillbug” at or near the top of the list of the most aerodynamic concept cars ever built, like the Ford Probe V of 1985, with a Cd of .137. It was essentially a space frame with the frame members going up through the cowl and over the doors. Nevertheless, the benefits and beauty that resulted, like this Pierce Arrow Silver Arrow (above), or Bugatti Atlantique coupe (below) are undeniable, but beyond our scope here. The Schlörwagen is a great example of this problem; its instability was the primary reason for its lack of success. Tesla Model 3 Elon Musk's electric cars are already breaking the mold, but they're also some of the most aerodynamic cars on the road. His approach was influential, and numerous companies used Jaray licensed bodies during the streamliner craze that unfolded in the early thirties. We’ve finally arrived at the place where highly aerodynamic cars are mainstream, but getting there was not without considerable turbulence. His designs eventually became more mainstream, and Mercedes, Opel, Maybach, and numerous other makes, primarily German, built special streamliner versions using Jaray bodies, like this Mercedes below: The limitation of these cars is like the Castagna Alfa, they were re-bodied conventional cars with frames, front engines and RWD. All the pictures I have see (the four I linked to) appear to be scans of a newspaper, unfortunately. I go to a fellow E28er’s get together. The commentators there were, well, eager to lump everything into Libs vs Dems vs Reps vs younameit; that put me off. Dunno why I seem familiar, but I only echo what many people feel but don’t say. History of Aerodynamics History of Aerodynamics The findings of Page 9/28 The pictures bring it to life, and I appreciate your efforts here (as well as in other fine series I’ve seen here since discovering the site). The mainstream industry forgot because the mainstream public did not care. Neil, The origins of streamlining go back two hundred years at least. My grandparents never owned a home. My info is that it had a Cd of 0.16, and it could go 150mph with a 150HP engine. I am/was not on TTAC. However, I’ve been a read-only user of TTAC for a long time, and CC since inception. The evolution of aerodynamics for LSR cars was remarkably rapid, as this Stanley Steamer Rocket of 1906 evidently shows. When a Gallon of Benzene was under 50 cents in Canada , what are the incentives to use small engine, especially a lot of distance in N America needs to cover in a hurry. An even less pragmatic but highly advanced American vehicle was the Stout Scarab (above). Also, I’d very much like one of those Lincoln’s please…good restorable condition is fine. Its important to note that the rise of interest in aerodynamics in the 1930s arose out of the desire to reinvent the automobile from its horse and wagon origins and based on the assumption that average driving speeds would be on the rise with modern highways to come. Nevertheless, the benefits and beauty that resulted, like in this Bugatti Atlantique coupe are undeniable, but beyond our scope here. I have another car that you could include; the 1939 Maybach Stromlinien Karosserie (aka Stromlinienkarosserie), which was a car that was made to do high speed tire testing: http://www.maybach.de/images/263_1.jpg It was a race car and based on the Rumpler. I think there’s a typo. Unlike the impractical and heavy Castagna Alfa, the Rumpler was as dramatically different (and influential) for its completely integrated and original design and engineering. During the fifties and sixties, with the exception of Citroen, Saab and a few other minor adherents, aerodynamics was largely left in the wake of increasingly ornate and boxy cars. Very beautiful streamlined bodies that also incorporated advanced engineering. That combination of light weight and outstanding aerodynamics would make a perfect commuter car. The Tropfenwagen was tested in VW’s wind tunnel in 1979, and achieved a remarkable Coefficient of drag (Cd) of .28; a degree of slipperiness that VW’s Passat wouldn’t equal until 1988. It become a formula, resulting in look-alike cars. Great article, but it should have included another few noteworthy production cars. The original Saab and of course the infamous Citroen DS and SM. That brings back memories of Bob Lutz stating that the Volt concept would have had better aerodynamics if they put it in the wind tunnel backwards. That earned it the nick name of “the Czech secret weapon”. http://img.photobucket.com/albums/v417/MikeMariettaSC/80MPG%20Honda%20Civic/sw38-ds04.jpg A fascinating read – it’s a coffe table-sized book with lots of text – not only nice to look at but nice to actually read, too. And a crude preview of Bonneville Lakesters to come. Putting it into practice was quite another story. Copyright 2011 - 2020 Curbside Classics. This made it a forward looking undertaking, as most drivers were still  plodding along at 35-45 mph outside of cities. As such, the Airflow predicted the same basic body packaging configuration as American cars from the late forties and early fifties, even if they weren’t so aerodynamically designed. Every car guy (or gal) worth their salt should look in awe at any car which sports a dorsal fin on purpose! That was too much of  a break for the symbolism still engendered in the remnants of the classic car prow. The KdF was designed to have a top (and cruising) speed of exactly 100 kmh (62 mph), and experiments showed that about 20hp would be adequate for that, with advanced streamlining. Thanks! This fairly radical design became tamed-down for the production 1936 front-engined Lincoln Zephyr, of which the less common but handsome coupe version is shown below: Of course, Americans’ introduction to streamlining had come two years earlier  in 1934, with the stunning Chrysler Airflow (below). It was one of the first mid engined race car and with it’s aerodynamic design, it looks a lot like the Auto Union Type C which had its debut a full 12 years later. 3 Aerodynamics History. The Rumpler was relatively very aerodynamic, but it was also quite tall and boxy, which resulted in the one hundred or so production cars being used primarily as taxis. Hopefully he was kidding. The luftwaffe staff dying of oversteer on the autobahns–Ludwinka’s revenge! I recall reading that due to a mathematical miscalculation, the Airflow’s structure was roughly twice the strength required for the application. To arrive at the critical total aerodynamic drag that determines power required (and efficiency), the frontal area (cross section of the vehicle looking straight on) is multiplied by the Cd (Cd x Ft²). After all, the energy used to overcome air resistance cannot be recovered – unlike with vehicle acceleration. It certainly appears to have sophisticated cooling vents (on the sides just behind the front wheels and the slots on the hood), and it had a full belly pan, too. Unfortunately, European cars suffer from what I call the `Small Car Syndrome’ where cars are made impractically small. Part 2 and 3 will be here shortly. Thank you for the excellent history lesson. The failure of the practical Airflow can probably comes down to one thing: that overly flat waterfall grille. Jaray only addressed the aerodynamics, not the complete vehicle like Rumpler had. Due to the excessively-heavy bodywork, it turned out to not improve on the top speed of the open Alfa it was based on. Flush windows, more aerodynamic mirrors, and smaller grille openings can make huge differences. As far as I can tell, there is no link to Article 3 from Article 2. Then in the 40s the mass market engines got more powerful and aero could be sacrificed to style. It’s important to remember that the Cd is a coefficient, and denotes the relative aerodynamic slipperiness of a body, regardless of its overall size. The Airflow. All Rights Reserved. Therefore, the designers devote an enormous amount of effort taming the airflow and generating downforce – just as their predecessors did, when this quest first started 35 years ago with the first wings of the Formula 1 cars… Wow Wow Wow! An even less pragmatic but remarkably practical and effective American vehicle was the Stout Scarab (above). This was a man who built a glider that never flew, and almost took flying lessons in Dayton, Ohio in 1910 from the Wrights, but couldn’t get the almost $1000 together. The evolution of aerodynamics for LSR cars was rapid, as this Stanley Steamer Rocket of 1906 evidently shows. The Rumpler’s shape was very aerodynamic, but it was also quite tall and boxy, which resulted in the one hundred or so production cars being used primarily as taxis puttering around Berlin because of their roomy minivan-like bodies. Varying cars had varying front wing widths, and you can see that some vortices actually hit the front tyre and are destroyed. It is used in most of the cars today specially in race cars because there is more need of aerodynamics in high speeds cars. Added basic lip sync, eye movement and animated black board drawings. Don’t think I ever heard of Tatra till I started reading CC. Where To Download A History Of Aerodynamics By Anderson aerodynamicists of our time. 1968: When Formula One Cars Grew Wings. You can either make cars the proper size, or you can use midgets as occupants. To put the nascent field of automotive aerodynamics in perspective, the typical two-box car of the twenties was more aerodynamic going backwards than forwards, as this ass-backwards car showed. The compact Tatra v570 of 1933 (above) is the forerunner of both the larger Tatras soon to come, and obviously of the Volkswagen. This Volkswagen prototype from 1934 (above) shows a very strong resemblance to the Tatra v570 indeed, with the benefit of some further refinement. This, combined with a wider body, dramatically improved interior space and accommodations. And the increase in speed was even more dramatic: the Rocket broke the 200km barrier, with a run of 205.44 kmh (127.66  mph). That would not be bettered until 1924, and not until 2009 for steam powered vehicles. This is probably how the car could fall end over end off a cliff and then drive away without even any broken glass. With a mid engine and swing axles at the rear, not only was it the direct ancestor of the legendary Auto-Union racing cars of the thirties, but of all mid-engined racing cars to this day. Chris Raber If I could purchase one car to show in a classic car meet, it would be the Tatra 77. A full size car can hold 27 gal on a fill up. I don’t know much about the history or whereabouts, more than it was based on a Volvo chassis, and built in 1933. One of the regulars is a guy who is a native of the town where Tatras were made. Tons of Tatras, check! It also explains the particularly strong interest and adoption of streamlining in Germany. through the flow. That 1939 Schlörwagen looks modern! The result was a striking Tatra-like car, with great detailing (e.g. https://en.wikipedia.org/wiki/Aurel_Persu. Notify me of follow-up comments by email. Aerodynamics is the science of airflow over airplanes, cars, buildings, and other objects. To arrive at the critical total aerodynamic drag that determines power required and efficiency, the frontal area (cross section of the vehicle looking straight on) is multiplied by the Cd. Headway in the world of aerodynamics was being made one lap at a time on racetracks across the world. I can’t get enough of these kids of articles right here. Why did they make these? And the increase in speed was even more dramatic: the Rocket broke the 200km barrier, with a run of 205.44 kmh (127.66 mph). Academia.edu is a platform for academics to share research papers. And already in 1865, Samual Calthorpe patented an “air-resisting train”, looking remarkably advanced given the times. That was too much of  a break for the symbolism still engendered in the remnants of the classic car prow. The Tropfenwagen’s influence in racing cars was much more immediate and lasting. He bought the local doctor’s ’33 Tatra roadster. Porsche/ VW settled with Tatra in 1961. Thanks! Search for “Mythbusters Clean Car vs. It is a comprehensive account, mostly railroads, about streamlining, but includes cars, planes and some industrial design. Rear steering – wow! An ironic ending for Rumpler, but his ideas spawned imitations and extensions world-wide, and opened the whole field. The first in a two part series looking into the F1 aerodynamic evolution. Thank you Paul. Required fields are marked *. It represents a state of aerodynamic efficiency in league with the most aerodynamic cars being considered today, such as the Aptera. Today’s production cars have to meet requirements like cost, safety, comfort. The aerodynamic efficiency of a car's shape is measured by its co-efficient of drag (generally known as its Cd figure). As with most questions asked on the internet, the Mythbusters have that one covered. By the time they reached the Carolinas, he realized it was a loser, but truly loved the design. Keep up the good work! Re: the Dymaxion car: I remember Bucky Fuller telling me that, on one test drive, when a cop hollered at him to get that thing off the road, he opened the window, put his hand on the cop’s head, and steered a circle around him before driving away. We’ve finally arrived at the place where a highly aerodynamic car like the Prius is mainstream. That earned it the nick name of “the Czech secret weapon”. These designers didn’t use spoilers and air dams, like modern ones do. air flow theory. It represents a state of aerodynamic efficiency in league with the most aerodynamic prototypes today, such as the Aptera. Again, fascinating articles! So many died at its hands, that supposedly Hitler forbade his best men to drive them. Great read! “Der KDF Wagen” is huge!! But this had relatively more to do with style (and even affectation) than a genuine effort to push the envelope in terms of leading edge aerodynamics. So why are modern streamlined cars so ugly if streamlined cars from the 1930s are so handsome (with a few exceptions)? Automotive aerodynamics is the study of the aerodynamics of road vehicles. The efforts to do so yielded some of the more remarkable cars ever made, even if they challenged the aesthetic assumptions of their times. A true pioneer. It’s important to remember that Cd is a coefficient, and denotes the relative aerodynamic slipperiness of a body, regardless of its overall size. I think I also saw one at the 2002 International Citroen Rally which took place in Amherst, Massachusetts that year. car aerodynamics make the car more safer and make it more fuel efficient. (Tatra Automotive History here). Peugeot was working on a V8 at the time, and an 802 streamliner was rumored to use this shape for the 1940 Paris automobile salon. According to Paul Schilperoord, who’s written about Josef Ganz, http://www.ganz-volkswagen.org/, Porsche, Ledwinka, and the European automotive scene in the 1920s and 30s, the patent dispute between Tatra and what became VW mostly had to do with the design of air-cooled horizontally opposed engines. With its .22 Cd and significantly reduced frontal area, it's no wonder this … please e mail me. A much more radical approaches to streamlining was Buckminster Fuller’s Dymaxion. Experimental Aerodynamics Car streamlining •!As aerodynamic principles became available to car engineers, the concept of streamlining was developed. When I said the motor looked just like a bug, he got a little hot and I learned about Porsche stealing the design. Although the visual cues are not really as significant as they might appear to us now, because these were the leading-edge design elements of the time, and widely imitated or shared, on both side of the Atlantic. I look forward to the next installment. I always thought GM should have taken the EV1, emptied the battery pack and motor and just added as small Tdi like found in modern VW Bluemotion Polo. Each side will say that their missions are in harmony, that good design should not preclude good aerodynamics… In common with many of the cars featured … It’s 4.8 meters long and has loads of passenger room and a huge trunk. It turns out that Erwin Komenda, who actually penned most of Porsche’s design and the KdF Wagem, visited the US in 1934, saw Tjaarda’s prototype, and admits being influenced by it. We’ll come back to Tatra later. Thank you. It had a mid-engined W6 engine, and four wheel independent suspension using swing axles which Rumpler patented. Jaray only addressed the aerodynamics, not the complete vehicle like Rumpler had. Other, more exciting design avenues were pursued. We’ll come back to Tatra later. This reduced aero drag but placed the CP (center of pressure) far forward and the CG (center of gravity) far aft. There is a basic tension between aerodynamic engineers and car designers. One of the many reasons I visit this site are the entertaining and informative historical posts. Its main goals are reducing drag and wind noise, minimizing noise emission, and preventing undesired lift forces and other causes of aerodynamic instability at high speeds. After he took over as chief design engineer at the Czech firm Tatra in 1921, he developed the basis of a series of remarkable Tatra cars and eventually streamliners with platform frames, independent suspensions and rear air-cooled engines that Ferdinand Porsche cribbed from heavily in his design of the Volkswagen (VW made a substantial payment to Tatra in the 1960s to compensate them for this theft of IP). It's unpleasant to think about, but imagine what would happen if you drove your car into a brick wall at­ 65 miles per hour (104.6 kilometers per hour). I always look forward to your consistently informative, insightful, and interesting articles. The Lincoln Zephyr (1936), a pragmatic adaptation of Tjaarda’s prototype, still retained its prow, and was a sales success, despite being not nearly as a good a car as the Airflow mechanically. That would not be bettered until 1924, and not until 2009 for steam powered vehicles. The La Jamais Contente (The Never Satisfied) was the first automobile to break the 100kmh (62 mph) record, in 1899. The cross-Atlantic influence were well at work already, although back than it was usually in the other direction. Wow, this is a terrific piece of work! Aerodynamics has become a key to success in the sport and teams spend millions of dollars on research and development in the field each year for improving performance. Fascinating article. If I recall correctly, the late-80’s GM A-bodies (Chevy Celebrity et al) especially the station wagons had remarkably low drag. And the increase in speed was even more dramatic: the Rocket broke the 200km barrier, with a run of 205.44 kmh (127.66  mph). Glass would shatter. That would not be bettered until 1924, and not until 2009 for steam powered vehicles. The first was built in 1932, and several more variations, a total of nine, were built in the mid thirties, but series production never got off the ground, due to an asking price almost four times higher than a Chrysler Imperial Airflow of the times, and even those weren’t selling so well just then.
