Oil tank filling system

The disclosure is entitled oil tank filling system. An oil tank filling system for filling the oil tank of a gas turbine engine that includes an aft core cowl is disclosed. The system includes an oiltank that has an oil tank top and an oil tank bottom and is located within a core of the engine, an oil access port located on the aft core cowl; and an oil tank filling pipe that leads from the oil access port to a tank filling port located at or adjacent the oil tank bottom. The system is configured so that oil that is supplied to the oil access port flows to and into the oil tank using gravitational force. A method of filling the oil tank of a gas turbine engine and a gas turbine engine that includes the oil tank filling system are also disclosed. 本公开题为"油箱加注系统"。公开了一种用于对包括后核心整流罩的气体涡轮引擎的油箱进行加注的油箱加注系统。该系统包括具有油箱顶部和油箱底部并且位于该引擎的核心内的油箱、位于该后核心整流罩上的进油口；以及从该进油口通向位于该油箱底部或邻近该油箱底部的油箱加注口的油箱加注管。该系统被构造成使得供应到所述进油口的油利用重力流至并流入该油箱。还公开了对气体涡轮引擎的油箱进行加注的方法以及包括该油箱加注系统的气体涡轮引擎。
