Problems solved by technology

[0003] At present, the fuel flow rate, spray cone angle, distribution unevenness and other tests of fuel nozzles are generally carried out independently with independent test equipment. In order to improve test efficiency, some manufacturers often hope that these three tests can be completed on one tool platform. In addition, now Some test fixtures are generally only designed for a single fuel nozzle, and cannot perform related tests on the fuel manifold. Therefore, it is urgent to design an integrated fuel nozzle test platform

Abstract

The invention belongs to the technical field of an aeroengine, and discloses a fuel nozzle testing platform. The fuel nozzle testing platform comprises a stand with a floor, a trunk pipe testing device which penetrates through the floor, a maldistribution degree testing device, a spraying cone angle manual measuring device and an automatic measuring device. The trunk pipe testing device and the maldistribution degree testing device are vertically arranged. The spraying cone angle manual measuring device and the automatic measuring device are parallelly arranged next to the long side of the rectangular floor. The trunk pipe testing device, the maldistribution degree testing device, the spraying cone angle manual measuring device and the automatic measuring device form a U-shaped path. The width of the U-shaped path is 700-900mm. The maldistribution degree testing device, the spraying cone angle manual measuring device and the automatic measuring device respectively comprise a testing clamp for mounting a single nozzle clamp or a trunk pipe nozzle clamp. The floor is provided with a plane rack which extends at the long side of the spraying cone angle manual measuring device and is used for placing a changed testing clamp. The side surface of the stand is provided with a lifting mechanism for climbing the floor by an operator.

Description

technical field [0001] The invention relates to the technical field of aero-engines, in particular to a fuel nozzle test platform. Background technique [0002] The fuel nozzle is the core component of the combustion chamber of an aero-engine, and its fuel flow rate, spray cone angle, distribution unevenness, etc. will directly affect the starting time and efficiency of the product. [0003] At present, the fuel flow rate, spray cone angle, distribution unevenness and other tests of fuel nozzles are generally carried out independently with independent test equipment. In order to improve test efficiency, some manufacturers often hope that these three tests can be completed on one tool platform. In addition, now Some test fixtures are generally only designed for a single fuel nozzle, and cannot perform related tests on the fuel manifold. Therefore, it is urgent to design an integrated fuel nozzle test platform. Contents of the invention [0004] The technical problem solved...
