CLF3 Transpiration Cooled Thrust Chamber Flow Minimization.
Abstract
This report describes the CTF Transpiration-Cooled Thrust Chamber Flow Minimization Program. The objective of the program was demonstration of the minimum coolant flow rate required for the CTF-cooled nickel chamber that had been built and tested on the Advanced Cooling Program. An existing transpiration-cooled thrust chamber, constructed with nickel platelets, was refurbished and tested at 1000 psia chamber pressure, 1000 lb thrust using CTF/MHF-3 as propellants and CTF as the transpiration coolant. Eight short-duration tests were made. The program goal of operation with 16% of total propellant flow used as coolant was not achieved. However, additional data were obtained on the effect of coolant flow rate on wall surface temperatures and on performance. Predictions of the performance loss due to the coolant at low coolant flow rates were verified. (Author)
