An AH-1G Cobra Helicopter minus the tailsection was mounted in a vertical position by personnel at the Ware Simulation Center, Rock Island Arsenal, and the response of the fuselage to various applied loads was then measured. The response, measured as deflections in the direction of applied load, will be used by Bell Helicopter Company for the validation of their NASTRAN math model of the Cobra Helicopter. Initial results of the test indicate good agreement between the experimentally measured deflections and the math model predicted deflections.
