Claim 1
Independent Claim
97 words
The method of subjecting an aircraft store to a simulated vibracoustic environment to determined structural integrity of the store comprising; subjecting a surrogate store to an actual inflight vibrational environment; recording the vibrational responses of the surrogate store; placing a store to be tested in an acoustic chamber; coupling acoustic energy at a given frequency to the chamber; measuring the vibrational response of said store while the acoustic energy is coupled to said chamber and adjusting the acoustic level until the vibrational response equals that previously recorded when the surrogate store was subjected to an inflight environment.
