Abstract

A general aero-engine on-wing cleaning jet device comprises a narrow-angle fan-type nozzle, a connecting assembly, a wide-angle fan-type nozzle, a first branch pipe, a balancing rod, a three-way joint, a main pipe, a liquid inlet and a second branch pipe. The general aero-engine on-wing cleaning jet device has the advantages that the device can be suitable for on-wing cleaning of multiple models of aero-engines, the technical problems of poor compatibility and large manufacturing difficulty of an aero-engine on-wing cleaning device are solved, and a technical support is provided for improvement of on-wing cleaning efficiency and the on-wing cleaning device.

Description

technical field [0001] The invention belongs to the technical field of aero-engine cleaning, and in particular relates to a general-purpose aero-engine on-wing cleaning spraying device. Background technique [0002] When an aircraft engine works for a long time, the output power of the turbine and the flow quality of the compressor will gradually decrease. This is because the pollutants in the air will enter the engine with the airflow and deposit on the surface of the engine blades, which will change the axial shape of the blades, thereby affecting the intake air flow, compression ratio and working efficiency. Therefore in this case the engine must increase the turbine inlet temperature and accelerate fuel consumption to compensate for the power loss caused by the above pollutants. [0003] Research on aircraft engine cleaning technology has always been a field with potential for development. When the engine blades need to be cleaned, the previous practice is to disassembl...
