EVALUATION OF GEARED FLAP CONTROL SYSTEM FOR TILTWING V/STOL AIRCRAFT

Abstract

The geared flap control system provides a means for controlling a tiltwing V/STOL aircraft in hover and transition flight without the use of auxiliary systems such as cyclic propeller pitch or tail jets/rotors. The system is based on using the flap as an aerodynamic servo to position the wing relative to the fuselage. Although the system is mechanically simple, the control characteristics are difficult to visualize because of the coupled body dynamics involved. Therefore, a comprehensive analytical and model testing program was performed to evaluate the system.
