Abstract: A lubrication system is disclosed. The lubrication system may be used in conjunction with a gas turbine engine for generating power or lift. The lubrication system utilized a flow scheduling valve which reduces lubricant flow to at least one component based on an engine load. The lubrication system may further include a main pump which may be regulated by an engine speed. Thus, a lubrication system which provides a lubricant to engine components based on the load and speed of the engine is possible. The system may improve efficiency of the engine by reducing the power previously spent in churning excess lubricant by at least one engine component as well as reducing the energy used by a lubricant cooler in cooling the excess lubricant. The lubricant cooler size may also be minimized to reduce weight and air drag due to the reduced lubricant flow.

Abstract translation: 公开了润滑系统。 润滑系统可以与用于产生动力或升力的燃气涡轮发动机结合使用。 润滑系统使用流量调节阀，其基于发动机负载减少至少一个部件的润滑剂流量。 润滑系统还可以包括可以由发动机转速调节的主泵。 因此，可以基于发动机的负载和速度向发动机部件提供润滑剂的润滑系统。 该系统可以通过减少先前由至少一个发动机部件搅拌多余的润滑剂而减少先前消耗的功率并且降低润滑剂冷却器在冷却多余润滑剂时使用的能量来提高发动机的效率。 润滑剂冷却器尺寸也可以最小化，以减少润滑剂流动导致的重量和空气阻力。
