Directed primarily to those responsible for the specification of loads for solid rocket motors, this report attempts to determine if present load specifications and specification practices are realistic. It concludes that present practices and particularly the resonance dwell requirement are not realistic since they (1) fail to account for the viscoelastic nature of the solid propellant grain, and (2) do not adequately handle the interaction between the rocket, its carrier aircraft, vehicle, etc. A summary of established techniques for predicting vibration environments is given and overall problem of design for dynamic loads is discussed.
