A Study of the Jet Stretcher Concept for Angle-of-Attack Testing

摘要

The feasibility of using a porous, axisymmetric jet stretcher for angle-of-attack testing of missiles having aft-located engine inlets was demonstrated. Initially, an analytical technique was developed for evaluating the performance of a jet stretcher and was applied to a small-scale experimental jet stretcher system for test body angles of attack of 4 and 8 deg. For each test body angle of attack the analytical technique was used to determine the optimum position of the jet stretcher and the regions on the jet stretcher that require porosity. (Author)
