Embodiment Construction

[0008] The specific implementation manner of the present invention will be described in combination with the drawings of the invention. Such as figure 1 , the system comprehensively considers the reliable oil supply of the engine 5 and the hydraulic load cooling system 10, and returns the heat dissipation of the engine 5 and the heat generated by the hydraulic load cooling system 10 to the aircraft fuel tank 12 in time. Two fuel pumps 14 are arranged in the consumption fuel tank 1 as hot backup for each other, and an independent suction fuel supply pipeline is also set up, and a check valve of the fuel supply pipeline is arranged on the fuel supply pipeline of the fuel supply pump 14 and the suction fuel supply pipeline 13. Ensure stable and reliable fuel supply to the engine 5 and the hydraulically loaded cooling system 10; a fuel supply cut-off valve 2 is arranged on the fuel supply main pipeline, which can cut off the fuel in the oil supply pipeline leading to the engine 5 ...

Abstract

The invention belongs to the technical field of aviation, and relates to a system for supplying oil to an engine and hydraulically cooling during the engine test. According to the system, fuel is supplied to the tested engine according to the pressure, flow rate and temperature of the engine as requirement, and the fuel absorbing the heat of a hydraulic loading system is timely combined with the returned hot fuel of the engine and then returned to a fuel tank of an airplane together; the measuring precision of the fuel supplied to the engine cannot be influenced by the temperature.

Description

technical field [0001] The invention belongs to the field of aviation technology, and relates to a system that takes into account both the engine oil supply and the hydraulic cooling system during the engine test process. Background technique [0002] In the engine air test, how to meet the functional integrity requirements of the engine oil supply system and the cooling requirements of the hydraulic load system? This is a difficult problem to solve. The system designed abroad can not meet the system requirements. Contents of the invention [0003] The invention can effectively solve the matching problem between the fuel oil supplied by the aircraft to the engine and the fuel supplied to the hydraulic load system for cooling in the air test of the engine. [0004] A system that takes into account both engine oil supply and hydraulic cooling during engine testing. The fuel in the consumed fuel tank 1 passes through the fuel supply pump 14 and the oil supply line check valv...
