INCREASED COOLING OF TURBINE ENGINE OIL

A method of operating a gas turbine engine powerplant for an aircraft to decrease maintenance time for the aircraft engine includes the step of increased cooling of the engine oil at the end of the cruise operative condition and at the beginning of idle descent to overcool oil and components in cont...

Zusammenfassung:	A method of operating a gas turbine engine powerplant for an aircraft to decrease maintenance time for the aircraft engine includes the step of increased cooling of the engine oil at the end of the cruise operative condition and at the beginning of idle descent to overcool oil and components in contact with the oil during the descent mode of the aircraft. Méthode d'exploitation d'un groupe motopropulseur à turboréacteur d'avion permettant d'en réduire le temps de maintenance et consistant à accroître le refroidissement d'huile dès la fin du vol de croisière et le début de la descente afin d'abaisser fortement la température de l'huile et des éléments de l'avion en contact avec l'huile.
