Aerodynamic Investigation of the Influences on a Submissile Flight Characteristic of (1) Body Ventilation and (2) a Panel Flying in Its Vicinity.

Abstract

In an attempt to explain observed submissile flight anomalies occurring during the Flight Demonstration Program of Assault Breaker Development, an aerodynamic investigation was conducted. Two wind tunnel tests were made: one investigated effects of submissile body openings with possible air flowthrough, and the other a submissile and a cover panel in close proximity - as might occur during ejection. Selected data from these tests are presented herein to illustrate these influences on the submissile's flight responses in the ejection plane. Test results revealed decreases in total normal force and fin lift with corresponding stability changes due to the existence of body slots, and the cover panel's presence produced flowfield changes that were equivalent to submissile attitude changes of approximately four degrees.
