America’s Rocket Propulsion Test Complex at NASA’s John C. Stennis Space Center (NSSC) has played a crucial role in the rocket engine development for over 50 years. Engines for all manned Saturn V and space shuttle flights were tested at NSSC.
Today, the center supports a variety of programs including testing of engines for the Delta launch vehicle and the next-generation engines that will carry humans to space. Accurate measurement of the rate of an engine’s fuel/oxidizer consumption is important towards understanding the performance parameters of the engine. Flow meter signals often have overshoot, ringing and noise on the pulse signal, which makes reliable triggering and frequency measurement extremely difficult.
Testing of rocket engines used for critical spaceflight missions requires accurate, reliable measurements. When the legacy signal conditioning systems at the NSSC rocket engine test stands were ready for an upgrade, Precision Filters’ 28000 system with 28524 Frequency to Voltage Converter and 28608B Filter/Amplifier was selected.
