Vibration Response of Ballistic Re-Entry Vehicles. Volume 1
Abstract
A technique is presented for predicting the vibration responses to re-entry aero-acoustic loading of high beta ballistic vehicles (those having a weight-to-drag ratio greater than 1500). Correlation of predicted responses due to ground acoustic loading and measured data is given and, based on these results, guidelines on the use of the prediction technique for acoustic and aero-acoustic loading are outlined. Computer programs for calculating vibration responses due to reverberant and progressive wave acoustic environments and to aero-acoustic excitations are documented and are available through the Air Force Flight Dynamics Laboratory (FY). Techniques for ground simulation of re-entry vibration response are discussed, and typical component design requirements and test specifications are delineated. The new feature of the technique is the use of finite element methods in deriving component test specifications. These more accurate test specifications will be essential in reducing the number of overdesigned components, thereby decreasing the cost of mission completion.
