Posted Image This illustration is by Robert Thatcher of the Road & Track Le Mans Special. It isn’t really a cutaway as much a phantom drawing showing component arrangement with the outlined body shape. That is appropriate as the car didn’t exist except as a study presented in a four-part series in the magazine in late 1957 and early 1958, written by the editor, John R. Bond. I believe that the reason for the articles was to stimulate interest for a Briggs Cunningham-like project to produce an American car capable of an overall win in the 24-hour race. It became apparent, part way through the series, that the preferred engine, the 283-cubic inch, fuel injected Corvette V8, was too large for the current rules.

The study also produced one of the nicest body shapes ever produced by the stylist Strother MacMinn. Aided by a group of aerodynamicists, the form addressed one of the key requirements for success at Le Mans: a high top speed enabled by a low drag coefficient. The proposed body shape is shown:
Posted Image
That cool-looking swept wing did not presage the application of downforce by 10 years. It is, rather, described as a “boundary layer air control device” whose purpose, apparently, was to prevent flow separation over the aft body. A few years later spoilers were being applied to promote separation to reduce rear-end lift. The advisory group tried to minimize cooling drag by ingesting all cabin and engine air at the nose. Under hood vanes were to direct the heated air out those scallops aft of the front wheel. A full belly pan reduced underbody drag and formed somewhat of a diffuser, but, looking at the elevation drawing with historical perspective, the car would have suffered massive front-end lift at the predicted 180 mph top speed, as did the near contemporary Scarab and Corvette Stingray.
Posted Image

While the body seemed to reflect the best current ideas, that cannot be said of the rest of the car shown in Thatcher’s illustration. I know it seems unfair to criticize a 50-year old design proposal, but was a ladder frame, inboard drum brakes, and semi-trailing arm suspension, front and rear, the best practices in 1958? The car’s mechanical engineering does not seem to exhibit much imaginative thinking, as exemplified by a suspension designed for 0.7g cornering as, to quote from one of the articles, “very few (if any) surfaces allow 1.0 g cornering”(!)

I still wonder how that thing worked. Did any other car company than Opel ever use it?

You should be able to work it out from this schematic. Incoming air is compressed via 'pressure waves' of exhaust gas. It is the notion of the pressure wave that perhaps causes confusion. I do have another schematic on file of the actual pressure wave process, if that is helpful.

Its first public outing, as Marc said, was with the Ferrari at Long Beach in 1981. (Not very successful on that occasion unfortunately). But Ferrari had the system (originally developed for heavy goods vehicles) on the bench as early as 1978.

The September issue of Practical Classics contains a cutaway of the 'Meadows Frisky' (So at least we now know it is out there) :) It also contains a couple of thumbnail sized Dino cutaways!


As does C&SC . I will scan trhe Frisky and post in due course.

Either it is Frisky season. Or this is evidence of a very definite shared editorial policy.

Adding to the collection of James A. Allington illustrations at this forum, here is the BRM F1 of 1964. This can be compared with the previous year's version at Post 2997. The cylinder heads have been changed to move the exhaust ports to the center of the V8, thereby cleaning up the area around the rear suspension.

Seems like it was not hostile at all. Just giving everyone a shot at it before it goes down, which seems reasonable. And, I do my own illustrations, as do quite a few of the members of the group, and it is about sharing the techniques and processes in the art ... not about hiding or "protecting" them.
Too bad you see it as a bit different than that, but that is certainly your right to do so.

Did we have thisone before?

@Mick144: If you don't want anybody to see your artwork, why do you make it in the first place?
Everybody here understands copyright issues. Nobody here understands your attitude. If that Midland F1 would have been in super high resolution ready to be abused to make posters of it and sell them we would understand you.
You don't want your work here? I don't want it either. With your attitude you can stick your work ## #### #### and get lost.
Have a look how much of their work Tony Matthews or Tom West contributed to this forum. I can't remember reading any complains of them about copyright violations of their work here.

You were not accused of anything. (Under your alter ego of 'calandarman') you were asked if the artwork on your site was all done by you. You replied in the affirmative, and your answer was accepted unreservedly. Here is the relevant exchange:

Did you create the art of these race cars or are you printing other people's art? I seem to recognize the point of view of the F1 cars done long ago having studied the same cars for my Historic Grand Prix Project. I am confused. I see you are also selling a cutaway of a lotus who created that?

Jim

Hi Jim

All the art on my site is created by myself! And those cars were created in the last six months or so! Blimey I.ve only just introduced my self and I'm getting the third degree already!

Very good! Can you post the Lotus cutaway? That looks great. Do you work in Illustrator or?

Posted Image Here is the B&W version of the BRM illustrated by James A. Allington and previously shown (colorized) at Post 3980. This image came from the December 1962 issue of Road & Track and is cataloged in this forum's index as a BRM P51. L.J.K. Setright identifies the 1962 BRM as the Type 56 in his The Grand Prix Car 1956-1966. As drawn by Allington this was the final variation of the exhaust headers tried during 1962. No matter how it is identified, this is the car in which Graham Hill won his first Driver's World Championship in '62.

Posted Image Here's another repost, but to a higher resolution, of that made at Post 4226. This is the 1960 Cooper Mk 1 T52 Formula Junior. This came from a reprint made for the Cooper Car Company of an article in the November 11, 1959 issue of The Motor. The illustrator, Brian Hatton, has shown a new product from a racing car company at the height of its success. The drawing shows many of the features for which Cooper was known, and often criticized: rear (actually mid) engine, of course, a frame of curved tubes with bracketry positioned wherever, transverse leaf spring at the rear, and cast magnesium bolt-on wheels with integral brake drums. It also shows a unique item for a single-seat racing car, a left-side located handbrake lever operating on the footbrake pedal (description provided in the reprint). Think about using this item to replace heel-and-toe downshifts and wonder who's steering the car with all appendages otherwise occupied.
