Zaschka became one of the first German helicopter pioneers. His machine is a striking representative of the Rotationsflugzeug (Zaschka calls it "rotating airplane"). Chief Engineer Engelbert Zaschka pursued in 1929 in Berlin, the approach of the folding-Zaschka three-wheeler. This city car concept was aimed to be cost effective and space saving by the vehicle could be folded after use sparingly. In 1934 Engelbert Zaschka completed a large human-powered aircraft. He was an inventor who held numerous international patents as it related to the helicopter
From 1921 till 1925 the design department of Orionette AG für Motorfahrzeuge in Berlin (Berlin SO 26, Oranienstr. 6) headed by Engelbert Zaschka, also produced some interesting unorthodox designs. Orionette is a historic German motorcycle brand.
The space and parking problems of the metropolitan areas was recognized in the 1920s. In 1929 Engelbert Zaschka invented a three-wheeled car in Berlin. Zaschka's car was a folding three-wheeler, designed so that it could be taken apart within 20 minutes. The car could be "knocked down" into three main sections. It was capable of a speed of from 25 to 30 miles an hour. The automobile of Engelbert Zaschka exhibited features that were important to U.S. inventor and architect Richard Buckminster Fuller and his Dymaxion car in 1933.
