Theoretical Investigation of the Flutter Characteristics of a Jet-Flap Helicopter Rotor in Hovering and Forward Flight

Abstract

A theoretical study of the aeroelastic characteristics of a jet-flap rotor system in hovering and forward flight was made. The effects of bending- to-torsion frequency ratio, center-of gravity location, elastic-axis position, and advance ratio on the aeroelastic stability of the system were obtained. Also investigated were the effects of control flap frequency and damping and jet blowing coefficient.
