ELECTRIC MOTOR DRIVEN LUBRICATION PUMP AND LUBRICATION SYSTEM PROGNOSTIC AND HEALTH MANAGEMENT SYSTEM AND METHOD

摘要

An aircraft lubrication supply system health and prognostic system and method includes supplying a pressure signal representative of lubricant pressure, a temperature signal representative of lubricant temperature, a speed signal representative of motor rotational speed, and one or more aircraft condition signals representative of one or more aircraft operating conditions to a system characterization model of at least portions of the lubrication supply system. Simulation response data representative of at least the pressure signal, the temperature signal, and the speed signal are generated, and lubrication supply system health is determined based, at least in part, on the simulation response data.
