Abstract

The invention discloses an intermediate oil supply device of a fuel oil system, and belongs to the technical field of aviation. The intermediate oil supply device comprises a tank body, an anti-leakage device, an alarm device, an oil inlet, an oil outlet, a supercharging device, a fuel oil blocking device, a settling tank, an oil drain valve and a tank body mounting bracket. The intermediate oil supply device of the fuel oil system has the advantages of being simple and reliable in structure, high in stability and suitable for various flight conditions and flight attitudes, it can be guaranteed that the aircraft fuel oil system supplies oil to a turboprop engine more accurately and stably, and therefore normal and stable operation of the engine is guaranteed.

Description

technical field [0001] The patent of the invention relates to the field of aviation technology, in particular to an intermediate fuel supply device for a fuel system. Background technique [0002] The aircraft fuel system is also called the external fuel system, because there is another system on the engine that delivers the fuel to the combustion chamber, which is called the internal fuel system. The heart of the aircraft - the engine relies on the combustion of fuel to generate heat to do work and propel the aircraft to fly. Fuel is the energy of the aircraft, and the fuel system is the supply system of aircraft energy. [0003] The main functions of the fuel system are as follows: store fuel; safely and reliably deliver fuel to the engine and APU under specified flight conditions; adjust the center of gravity to maintain aircraft balance and wing structure stress. [0004] There are two main types of engines used in general aviation aircraft: aviation piston engines and...
