This paper presents the philosophy and requirements for an integrated aerospace dynamic program. This aerospace dynamic program encompasses a full range of dynamic tests and analyses required to evaluate, develop, and qualify an aerospace vehicle.This presentation commences with a brief history of dynamic tests and analyses conducted during the past two decodes and continues with some notes on the development and design of aerospace vehicles utilizing present-day analytical and test techniques.Analyses are required to establish dynamic criteria and structural integrity of the aerospace vehicle. Dynamic criteria include shock, vibration, and fluctuating pressure excitations during various phases of the vehicle’s life. Thus, criteria should be predicted for the transportation phase as well as for the flight mission. Analytical techniques should be used to predict liftoff excitations, aerodynamic excitations, engine transients, ordnance excitations, entry dynamics, and landing dynamics. Dynamic analyses are required to determine structural modes, frequencies, and responses for the evaluation of structural design and guidance system functions. Dynamic response of large equipment masses should be computed. Math models with varying degrees of complexity are required with matching computer programs.Dynamic analyses should be verified by ground test programs and flight test programs. Dynamic measurements should be made during transportation and flight to establish or verify environments and to assess the structural effects. Shock tests, vibration tests, and acoustic tests should be conducted to supplement analytical predictions and to test structures and equipment. Tests are required to verify dynamic environments, structural modes, structural integrity, and dynamic responses of local structure and large equipment masses. Wind tunnel tests should be run to study flutter characteristics of the structure and to refine fluctuating pressure levels in clean areas, protuberance areas, and bow shock areas.The intent of this paper is to provide an integrated dynamic program that combines essential dynamic analyses and tests for the purpose of developing and designing an optimum structure for an aerospace vehicle.
