Criteria for Contamination Level in Flight Control Systems 680190

This paper presents a new concept and technique for solving the problems associated with the prediction and control of flight component failures which are attributed to contamination of the power transmission fluid in the servo actuating subsystem. Basically this technique assumes that these failures are probabilistic. Mathematical models are then established and comparisons made between calculated and measured values of contamination in a system to determine the degree of acceptability of the fluid.
