Title: Low-Cost, High-Performance Combustion Chamber for LOX/CH4 Propulsion
Agency: NASA
Contract: NNX10CD15P
Award Amount: $100,000.00
 

Abstract:

Ultramet will design and fabricate a lightweight, high temperature 5-lbf combustion chamber for use with cryogenic liquid oxygen/methane (LOX/CH4) propellant that will deliver a specific impulse of ~355 seconds, an increase over the current 320-sec baseline that will result in a propellant mass decrease of 55 lbm. The material system will be based on Ultramet's proven oxide-iridium/rhenium architecture, which has been successfully hot-fire tested with stoichiometric oxygen/hydrogen for hours. Instead of rhenium, however, the structural material will be a niobium alloy that has excellent high temperature yield strength. With a yield strength-to-weight ratio over 33% greater than that of rhenium at elevated temperature, this niobium alloy will significantly reduce chamber weight. The starting materials are two orders of magnitude less expensive than rhenium and are less expensive than the C103 alloy commonly used in low-performance engines. Aerojet will design the chamber in Phase I and will perform hot-fire testing in Phase II. Phase II will include scaleup of the process and testing of a chamber in the 25- to 500-lbf thrust class, which would be suitable for a reaction control system engine on a lunar ascent/descent vehicle.
