The Ho III d Motorglider
Troubles plagued the project in the beginning, and it was October before the first powered flight was made. Constant engine problems kept the machine on the ground most of the time, and not until a larger engine with 50% more power was installed, did our troubles subside. From then on, the licensed workmen in the plant were encouraged to fly it, and considerable flying time was accumulated. In February 1943, I had the opportunity to demonstrate the Ho III before Professor Prandtl. While I explained my bell shaped lift distribution theory, Scheidhauer made a very convincing flight demonstration of its forgiving slow flight behavior, by doing whip stalls at hangar roof level. This resulted in a for us very favorable report from the professor to the Air Ministry. |
