About this award
This award to Wask Engineering, Inc., a small disadvantaged business, is for the development of a piezo-actuated throttling valve for use in a 100 lbf liquid oxygen/liquid methane reaction control system (RCS) thruster. The valve is intended to rapidly adjust the propellant mixture ratio to prevent hardware damage and allow continuous throttling from zero to full thrust. The $747,811 Firm Fixed Price contract, awarded by the National Aeronautics and Space Administration (NASA) Shared Services Center, is a Phase II Small Business Innovation Research (SBIR) effort to refine the valve design, verify cycle life, and measure leakage. The valve design is configured for cryogenic propellants and leverages Wask Engineering's prior experience with similar piezo-actuated valves demonstrating long cycle life and low leakage rates.
Description
Wask engineering proposes to refine the design of an piezo actuated throttling valve fabricated in phase 1 that has demonstrated the ability to open within 2.6 msec to meet the requirements of a 100 LBF RCS thruster. This includes verifying the valve cycle life and valve leakage amounts. Similar valves designed by wask engineering have operated for more than 2X109 cycles while maintaining a leakage rate of less than 1X10-3 sccm of he. The current valve design is configured to operate with cryogenic propellants and support the flow rates requried for a 100 LBF liquid oxygen/liquid methane thruster. A piezo actuated valve has many benefits for RCS thrusters. The speed with which the valve can adjust its throttle position means that with two such valves the thruster propellant mixture ratio can be rapidly adjusted to prevent hardware damage. The valves have the ability to continuously throttle over a range of thrust levels, allowing the thruster to operate from zero to full thrust. The piezo crystals use very little power, reducing the overall power consumption, again reducing weight.
