Influence of Turbine Engine Lubricant Load Carrying Ability on Gear System Design.

摘要

The objective of this study was to evaluate the effect of lubricant load-carrying ability on the design of gear systems in aircraft turbine engine accessory and main power transmission gearboxes. Five gearbox designs, representing a wide range of applications and power levels, were analyzed to assess any payoff, in terms of weight reduction and life cycle operating cost, which may be possible through the use of lubricants possessing increased load-carrying ability. The designs included a modern transport engine, JT9D-7, accessory gearbox; a current fighter engine, TF30-P-100, accessory gearbox; a turboprop, T34, main power transmission gearbox; a proposed turbofan, QCSEE, main power transmission gearbox reflecting advanced technology and a helicopter, CH53, gearbox.
