Abstract : The estimated performance capabilities of the Lockheed XQ-5 Supersonic Target Drone based on predicted aerodynamic characteristics are presented. Maximum speed and altitude of the vehicle are presently limited by the guaranteed flight envelope of the powerplant to a Mach number of 2.7 and an altitude of 60,000 feet. The operational duration of flight meets the design requirement of 9.3 minutes at a Mach number of 2.7 and an altitude of 60,000 feet. The operational duration of flight meets the design requirement of 9.3 minutes at a Mach number of 2.7 at 60,000 feet. From an air launch at 30,000 feet, the vehicle is capable of attaining a maximum speed of Mach number 2.7 at 60,000 feet, achieving a maximum range of 275 nautical miles, and accomplishing complete recovery of the vehicle with no significant damage to the powerplant, airframe, or equipment. Maximum range is extremely sensitive to cruise altitude as evidenced by the fact that maximum range is reduced from 275 nautical miles for a cruise altitude of 60,000 feet to 77 nautical miles for a cruise altitude of 25,000 feet. Excellent maneuverability potential is indicated by the fact that 2.25 ''g's'' normal accelerating force is abailable at Mach number 2.7 at an altitude of 60,000 feet. (Author)
