Throttleable to 30% of thrust, sea level version of RL10. Four engines were built and were used on the DC-X and the upgraded DC-XA VTOVL SSTO launch vehicle demonstrators. First flight 1993. Number: 48 . Thrust: 64.70 kN (14,545 lbf). Unfuelled mass: 143 kg (315 lb). Specific impulse: 373 s. Specific impulse sea level: 316 s. Burn time: 127 s. Height: 1.07 m (3.51 ft). Diameter: 1.02 m (3.33 ft). The DC-Y was a conceptual vehicle design and did not use these engines. The RL-10A-5KA was proposed for use on the Kistler K-1 vehicle but was not selected. Thrust (sl): 54.800 kN (12,320 lbf). Thrust (sl): 5,591 kgf. Engine: 143 kg (315 lb). Chamber Pressure: 39.12 bar. Area Ratio: 4. Thrust to Weight Ratio: 47. Oxidizer to Fuel Ratio: 6. Coefficient of Thrust vacuum: 1.5. Coefficient of Thrust sea level: 1.37. Country: USA. Engines: RL-10A-5. Launch Vehicles: DC-X, Delta Clipper, DC-XA. Propellants: Lox/LH2. Agency: Pratt and Whitney.
