The Influence of Aerodynamic Decelerators on Supersonic Wakes: With an Application of the Gas Hydraulic Analogy

摘要

Two-body performance characteristics can be predicted with a reasonable degree of accuracy for deployable aerodynamic decelerators operating in conventional supersonic wakes. However, under certain geometric and flight conditions, the decelerator can modify the base flow region of the forebody, thus invalidating the performance prediction techniques. A literature review, supplementary wind tunnel tests, and a large number of shallow water tow table tests were performed to obtain a description of the process of wake modification and identify those parameters that influence the process.
