Contamination Measurements from a 5 lb sub f Thrust Bipropellant Engine - Phase II.
Abstract
A Bipropellant Rocket Engine plume contamination test program was conducted in the Aerospace Chamber (10V) between Sept. 25 and Oct. 20, 1978. During the four week test period a 5- lb sub F thrust rocket engine was fired over a range of engine operating parameters in a cryogenically pumped vacuum chamber where the background pressure was maintained below 1 x .0000001 torr. A vidicon image intensifier coupled spectrometer (VICS) system was used in conjunction with an electron beam to make number density and rotational temperature measurements of gas species (N2, CO, CO2, and H2/H20) in the forward flow region of the rocket nozzle. A photomultiplier tube was used in place of the vidicon to make number density and temperature measurements of N2 in the plume backflow region. Forward flow laser light scattering measurements were made with the VICS system to characterize the particle size and particle number distributions in the plume core. Mass flux measurements were made in the plume backflow region (60 degrees-135 degrees off axis) with cryogenically cooled quartz crystal microbalances (QCM's). (Author)
