説明
This paper investigates helicopter rotor instability coupled with its support structure. The modal analysis is executed for a system of four rotor blades which permit a hub motion, a lagging motion, and a flapping motion. Then, an approximate formula is derived for estimating the rotor speed where the ground resonance modes become unstable. The possibility of instability is also proved by taking account of the aerodynamic coupling between the whirl modes and the scissors modes, where this possibility is not trivial because each mode is neutrally stable.
