The validity of the reduced-mass method of representing wing-lift effects in free-fall drop tests of landing gears has been investigated by means of tests of a small landing gear in the Langley impact basin. The behavior of the landing gear in the reduced-mass drop tests is compared with results obtained in simulated air-borne impacts, in which wing lift forces were mechanically applied to the test specimen during impact, and with the results of free-fall drop tests with full weight.
