The report presents the results of a series of tests in the supersonic wind tunnel at the University of California at Los Angeles to evaluate the stability of the data recovery vehicle being developed for the Hyper-environment Test System 609A. The tests, which were conducted at M 2.87 confirmed that the vehicle with the blunt base was stable at alpha 180 degrees. This stability was eliminated by the addition of a cruciform fin configuration to the aft surface of the reentry body. Author
