Standoff mounting for air data sensing probes on a helicopter

摘要: A standoff arm and probe assembly (20) for a helicopter (10) has mounting (22, 70) that extends outwardly from the body (18, 72) in selected direction, preferably forwardly. The an outer end (24) mounts low lateral speed sensing (26, 88) is positioned with axis substantially parallel to of rotor (12), within downwash region air movement caused by (12). ports (30, 90) are arranged annularly around 88), pressures sensed at annular or peripheral locations on measured determine speeds. Additionally, can mount plurality other sensors (44, 50, 52, 56, 58, 60, 76, 78, 82, 94, 96, 98) such as pilot pressure 82) extending forwardly arm, (50, 78) along side 70), (22) outside temperature (56, 94), ice detectors (58, 96), total (60, 98), if desired.
