Marcel Leyat

Marcel Leyat was an engineer, inventor, aviation pioneer, and aeronautical and automobile manufacturer. He graduated from the École Centrale Paris in 1907. From 1908, he worked for the Société Astra and built a biplane glider called the Quand Quelle. In 1909 he targeted "the first powered crossing of the English Channel", but Louis Blériot succeeded on July 21, three weeks before his De Dion-Bouton 5 hp powered plane completed a flight of at elevation on August 15. In 1910, he built a propeller-driven biplane long and wide. He obtained the FAI pilot's license in 1911. During the First World War, he built several aircraft, including a "living wing" bomber. In all, he designed and built around thirty different aircraft up to World War II.

Description

The first model was called Hélica, also known as 'The plane without wings'. The passengers sat behind each other as if they were in an aircraft. The vehicle was steered using the rear wheels and the car was not powered by an engine turning the wheels, but by a giant propeller powered by an Scorpion engine. The entire body of the vehicle was made of plywood, and weighed just 250 kg, which made it dangerously fast.

Performance

In 1927, a Hélica reached the speed of at the Autodrome de Linas-Montlhéry circuit. Leyat continued to experiment with his Helica. He tried using propellers with two and four blades.

Production

Between 1919 and 1925, Leyat sold 30 vehicles.
