Engelbert Zaschka (1896 in Freiburg im Breisgau, Germany – June 26, 1955 in Freiburg im Breisgau, Germany) was a German chief engineer[1], chief designer and inventor.[2] Zaschka became one of the first German helicopter pioneers. He is a striking representative of the Rotationsflugzeug (Rotary-Wing Airplane).[3]

In 1927[4] Engelbert Zaschka of Berlin built a helicopter, equipped with two rotors, in which a gyroscope was used to increase stability and serves as an energy accumulator for a gliding flight to make a landing. Gliding in this case means a straight descent. He wanted to develop an efficient propeller drive.[5] The machine was a combination of an autogyro and a helicopter. The principal advantage of the machine, Zaschka says, is in its ability to remain motionless in the air for any length of time and to descend in a vertical line, so that a landing may be accomplished on the flat roof of a large house. In appearance, the helicopter does not differ much from the ordinary monoplane, but the carrying wings revolve around the body. In 1934[6] he completed a large human-powered aircraft, the Zaschka Human-Power Aircraft.
From 1921 till 1925 the design department of Orionette AG für Motorfahrzeuge in Berlin[7], headed by Engelbert Zaschka, also produced some interesting unorthodox designs.[8] Orionette is a historic German motorcycle brand.
In 1929 he invented a three wheeled car, an automobile which could be assembled quickly in domicile or set aside.[9]
