Abstract : Drag brakes are disposed around the rocket nozzle and are normally carried in closed position. The brakes rotate about axes normal to the centerline of the rocket. A spring is used to provide the torque necessary to initiate drag brake opening, and the brakes are held in extended position by the combined effects of the spring torque and the aerodynamic forces. The drag brakes are allowed to open only if an electrical signal is received to actuate a squib or solenoid valve associated with each pair of drag brakes. If no signal is received the brakes will not be extended. (Author)
