In the 1900s, France spent a significant amount of money on airplane development ($22 million compared to one-half million by the U.S.) Believing propeller power was the most efficient means of moving a vehicle, entrepreneurs built propeller-powered cars. This one-of-a-kind Helicron was discovered in 2000 in a barn where it had been placed by the original owners in the late 1930s. The Rosengart chassis, suspension, and brakes are original although the builder turned the frame around 180 degrees to allow the rear wheel to steer. This meant significant modifications needed to be made to the chassis. After discovery, the Helicron was completely rebuilt using many of the original components. Unfortunately, the original motor is lost to time; in its place is a 1980s Citroen GS 4-cylinder motor that will propel this 1,000 pound vehicle to 75 mph. The original builder's plans to produce this car were never accomplished.
This car was built in France in 1932. Following the First World War it was not uncommon for recently displaced airplane engines to look towards the burgeoning automobile industry for more lucrative employment. As in this example, a few entrepreneurs developed propeller-powered cars with the notion that a propeller was an efficient means of moving a vehicle. This one-of-a-kind, propeller driven car was discovered in a barn in France in 2000, having been placed there by the original owner in the late 1930's.
It was completely rebuilt but many of the mechanical components are original, including the frame, wire wheels, dashboard, steering wheel, steering gear, brake pedal, light switch, headlights, and the type plate.
The wood frame was sandblasted and treated, the steering gear was rebuilt, and the interior was upholstered. The car steers with the rear wheels and only those wheels have springs. It is currently equipped with a Citroen GS engine with the propeller coupled directly to the crankshaft.
This Helicron passed the French safety inspection in 2000 and is approved for use on the roads. When the wooden propeller is spinning at full rpm, this little 1,000-pound boat-tailed skiff can hit freeway speeds exceeding 75 mph. As you might expect, this is the one and only Helicron in existence. © 1998-2009. All rights reserved. This material may not be published, broadcast, rewritten, or redistributed.
