New Type Gyro Plane Tested on Electric Rail Carriage (Jan, 1932)
New Type Gyro Plane Tested on Electric Rail Carriage
AS interesting as is the new type of gyro plane now undergoing exhaustive experiments in France, the method of testing is perhaps of even more interest.
The trial carriage is electrically driven and attains a speed of from 60 to 80 miles an hour on rails. By means of measuring instruments on the carriage, the wind pressure, lifting power, derivation of lift, and the stresses on various parts are registered.
The plane itself is of the conventional type, except for a pair of large propellers, which turn in opposite directions, mounted on a stub shaft above the plane. These propellers work by wind pressure.
