REPORT NATIONAL ADVISORY COMMITTEE FOR AERONAUTICS lack of reliable information on the propeller character- from the ratio between the vertical velocity and true istics, no attempt was made to calculate thrust directly air speed. The attitude of the autogiro was recorded Figure 1—Three-quarter view… … Figure 2.—Swivel suspension for flight-path-angle and air-speed recorder speed to develop varied small amounts of positive tion of the change in flight-path angle from that at the thrust.
