IFOS proposes to develop a test rig sensor suite to measure pressures/acoustics, static and dynamic strains and temperatures for advanced propulsion systems such as that used for NASArsquo;s Space Launch System (SLS) and SpaceXrsquo;s Starship IFOS will leverage off its experience in the turbine engine industry and harsh environment sensors. The system incorporates multiplexed optical fiber sensors adapted to measuring temperature, dynamic pressure/acoustics, static and dynamic strain at high sampling rates. Compared to existing ground testing technology, the system has greatly simplified design, reduced size, and expanded sensing capability in terms of number of sensing points, multi-functionality and overall precision. Phase I will demonstrate feasibility and Phase II will develop and deliver an engineering prototype for transitioning to NASArsquo;s test rigs. The proposed test rig sensor suite will assist rigorous ground testing to. It will faciltate minimization of test program time, cost, and risk including mitigate propulsion system risks inherent in spaceflight as well as meet existing environmental and safety regulations.
