A famous of these interwar period saucer shaped aircraft designs, has to be credited to Lee Richard. In 1922 this English man invented a circular wing aircraft, known as an Annular Wing. The vehicle had a standard fuselage, but the wing was hoop shaped. It had a top speed of 130 kilometers per hour, and a top taxi speed of 35 kilometers per hour. There is even a scale model if it at a science museum in London.
One of these lesser-known figures, predating was Wright brothers initials flight was August Wilhelm, who was known for making his own concept of flight with saucer shaped vehicles. Zachariae was a mathematician and early aviation theorist, who wrote many scientific papers on using circular wings to provide lift. Unfortunately, none of his theories or hypothesis were ever pursued.
