Random Aerodynamic Oddity of the Day Thread

[freebeard]

It's an aerodynamic oddity becasue it's an air compressor?

Thomas Smith began the Smith Model A Motor Compressor Co when he realized how much air compressors were needed in industry, and construction, by rethinking junkyard Model As

Smith designed a clever system to retrofit a used Model A.

He patented a cylinder head for the car’s 40-horse four-cylinder:
Cylinders one and four burned gasoline, powering the engine as usual;
two and three pumped air into a reservoir tank mounted on the car

It reminds me of the Dunn-Right compressor, also based on a 4-cylinder 40HP base engine.

Maybe the front was lowered/rounded for better visibility?
Still, looks nice

One wonders how well it would fit an F-150.

[cRiPpLe_rOoStEr]

The cab is basically the same of a bricknose or OBS F-150 anyway...

Not sure if that was taken as a priority at the designing stage, but most likely it was easier to mould. The tilt-cowl is a single-piece fiberglass unit.

It never flew. Taxi tests only, and problems with the clutches meant it never made the 1929 race.

Brilliant concept, ahead of it's time?

My thought was an electric conversion would obviate the clutch problem.

Know anybody that makes R/C models?

That looks so strange with the longitudinal leaf-springs, instead of the transverse leaf-springs which were originally fitted to full-size Fords at least until the '40s.

It makes sense. A traverse spring requires a wishbone or radius rods.
