Abstract:

The objective of this program was to establish a technical data base to support future development of GO2GH2 flight thrusters for a Space Station Auxiliary Propulsion System. Specific issues of concern were thruster performance and cycle life. To address these issues, NASA funded Aerojet to design, fabricate and altitude test two 25-lbf GO2.GH2 thrusters. The first thruster was designed to operate at a nominal mixture ratio OF of 4.0 and expansion area ratio of 1001. It was tested over a range of OF from 2.0 to 8. 0, achieving a range of specific impulse Isp from 440 to 310 lbf-seclbm. The second thruster was optimized for a nominal OF of 8.0 at a lower nozzle expansion area ratio of 301. This second thruster was tested over an OF range of 3.0 to 9.5, achieving an Isp range of 416 to 3323 lbf-seclbm, respectively. At OF 8.0, the Isp was 360 lbf-seclbm, as predicted.
