The Effects at a Mach Number of 6.86 of Drag Brakes on the Lift, Drag, and Pitching Moment of an Ogive Cylinder

J. A. Penland, D. E. Fetterman

Abstract

Memorandum presenting results of three-component force tests of a cylindrical body with an ogival nose equipped with panel-type drag brakes each covering approximately 21 percent of the body circumference and located on opposite sides of the body at the rear end. Results regarding the drag brakes in the horizontal plane, drag brakes in the vertical plane, comparison of drag brakes, and minimum drag are provided.
