Measuring Rotor Dynamics in Cryogenic Turbopumps
Measuring rotor dynamics inside a cryogenic turbopump is one of the hardest sensing jobs in aerospace propulsion. The environment can include liquid oxygen (LOX), liquid hydrogen (LH2), or liquid methane (LCH4), plus high pressure, extreme cold, vibration, and electromagnetic noise. Regardless of these difficulties, engineers still need clean data on gap, speed, and deflection. That … Continue reading
