GUST EXPERIENCE OF A HELICOPTER AND AN AIRPLANE IN FORMATION FLIGHT

摘要

A single-rotor helicopter and an airplane have been flown in formation in rough air for the purpose of measuring and comparing the responses of aircraft to gusts. Rough-air flights were also made by the helicopter alone at several airspeeds over the same ground path.nThe results indicated a somewhat greater gust alleviation for the helicopter than for the airplane over the speed range investigated. In addition, a substantial effect of speed on the normal accelerations of the helicopter due to gusts was observed.
