Abstract : This report presents the estimated stability and control characteristics of the Lockheed XQ-5 Supersonic Target Drone. The test vehicle is of conventional design except for the ramjet engine mounted on a strut below the fuselage. Boost of the test vehicle to ramjet engine operating Mach number is accomplished by two underwing mounted solid-propellant rocket bottles. Boosters are ejected at rocket burnout and the ramjet engine supplies thrust for the vehicle during the climb to altitude, course cruise, and terminal phases of the flight, until fuel exhaustion. Recovery of the vehicle after fuel exhaustion is accomplished by deployment of parachutes. Control of the vehicle is provided by an autopilot which actuates an all-movable horizontal stabilizer and conventional aerodynamically balanced outboard ailerons. Longitudinal control is accomplished by stabilizer deflection and lateral or roll control by aileron deflection. Directional or heading control is accomplished by combined stabilizer and aileron deflection as a rudder is not incorporated in the design. (Author)
