A simplified method of lifetime
monitoring of aircraft engines key components suggested, designed to account
for lifetime in case of temporary disability automated software system. The
method is based on use of well-known simple work off counter and allows
partially taking into account the influence of engine operating conditions,
particularly the temperature at the inlet to the engine, on the number of
worked off standard operating cycles . By the example of AI-450-MS major engine
parts showed that the proposed simplified method of monitoring makes it
possible to reduce the errors level of well-known simple work off counter up to
two times.
Key words: lifetime, monitoring,
damaging, resource counter.
