Random Vibration Above 2000 Hz: Deriving and Verifying an MPE for Engine-Proximate Components

The Problem Here is a problem that comes up more often than the standards would suggest. An engineer is deriving a random vibration maximum predicted environment (MPE) for launch vehicle components mounted very close to the engines. Accelerometer data from engine test stand and stack tests show significant broadband energy above 2000 Hz, with peaks ... Read more
