Bell 8048

Bell Nitric acid/UDMH rocket engine. Out of production. Used on Agena A, derived from Rascal engine. Regeneratively cooled; used drilled holes to create the same effect as more costly stacked spaghetti rubes. First flight 1959.

Harry Meyers made a major contribution to the development of Bell's Rascal and Agena engines. Although both of these engines were made of aluminum, the Agena started with a thick walled cylinder, and used a series of adjacent 3/16 inch drilled holes to create the same effect as stacked spaghetti rubes. These thrust chambers were coated, and worked well in the Agena engine.

Engine: 127 kg (279 lb). Chamber Pressure: 10.00 bar. Area Ratio: 20. Propellant Formulation: RFNA/UDMH. Thrust to Weight Ratio: 55.3622047244095. Coefficient of Thrust vacuum: 2.03929071027152.
