SUMMARY OF LOW-SPEED WIND TUNNEL TESTS ON A 12.5(-SCALE MODEL A4D-5 ESCAPE CAPSULE

Abstract

A brief series of tests were conducted on a 12.5%-scale model A4D-5 escape capsule in the Douglas El Segundo 30 x 45-inch low-speed wind tunnel to obtain the aerodynamic characteristics of the basic capsule configuration after ejection from the airplane and to determine the effects of the nose gear door and of various stabilizing devices on the capsule logitudinal, lateral and directional stability. Results of these limited tests indicate that the basic capsule configuration is statically unstable longitudinally and directionally but that sufficient stability can be achieved through the use of stabilizing surfaces with further wind tunnel development. In this connection it would also be noted that the level of required static stability is subject to a dynamic analysis of the capsule motions. (Author)
