Bipropellant Attitude-Control Rocket (ACR) Plume Contamination Investigation.

Abstract

This report presents the results of the bipropellant Attitude-Control Rocket (ACR) plume contamination investigation. The objectives of this effort were to collect and weigh under vacuum conditions the amount of exhaust contaminant emanating from the nozzle lip (along the nozzle exit plane) at injector hardware temperatures of 40, 75 and 110 degrees F, and identify the contaminant. Tests were conducted under vacuum conditions using a RIE attitude-control rocket engine. The propellants were nitrogen tetroxide (N2O4) and monomethylhydrazine (MMH). The analysis of the test data revealed that more exhaust contaminant will be produced from the nozzle lip at the lower injector hardware temperature. The exhaust contaminant has been identified as monomethylhydrazine nitrate. (Author)
