Analytical Study of Inflight Thrust Reversers. Volume I

摘要

Mathematical models are developed for predicting the flow fields within and external to a thrust reverser when it is deployed in flight, and the forces and moments induced on the aircraft by virtue of these flow fields. The method used are largely two-dimensional in nature, but contain empirical corrections to account for three-dimensionality. Although no testing was accomplished under this contract, the analytical predictions are compared with existing test data. A method of evaluating stowed reverser losses is given, twin-jet and unsteady flow effects are discussed and a test/analytical program is outlined which is aimed at further improving and verifying the results of the study. This volume contains the technical discussion and results of the analytical effort. (Author)
