Title:
【発明の名称】回転翼航空機用ピッチ制御システムにおける動力学的短縮効果の補正装置および方法
Document Type and Number:
Japanese Patent JP2768827
Kind Code:
B2
Abstract:
A rotor for a rotary wing aircraft includes a rotor shaft driveably connected to a power source, a rotor hub connected to the rotor shaft, rotor arms inclined with respect to a plane perpendicular to the rotor axis and pitch shafts supported on each rotor arm. The rotor arms each support a pitch shaft for pivotable movement about a pitch axis. A pitch beam carries flexures, each connected to a pitch arm at a location offset laterally from the associated pitch axis. The flexures driveably connect the pitch arms to the pitch beam and transmit pitch control motion to the blades as the pitch beam moves along the rotor axis. Each flexure is intentionally displaced by bending radially during installation in a direction that reduces forces among components of the flexure bearings developed during operation.
