Abstract

Disclosed is an adjustable and fixed aero-engine on-wing washing frame comprising a narrow-angle fan-shaped nozzle, a connecting assembly, a main pipeline and a first pipeline, a liquid inlet is formed in one end of the main pipeline, the end of the first pipeline is connected with the narrow-angle fan-shaped nozzle through the connecting assembly, the main pipeline is a U-shaped pipe, and a balance rod is vertically arranged at the bottom of the U-shaped pipe; a washing frame fixing device perpendicular to one side of the U-shaped pipe is arranged at the liquid inlet end; the communicating position of the first pipeline and the main pipeline is a right angle and is fixed to be a right triangle through the water spraying pipe supporting device. The invention has the beneficial effects that the invention can be suitable for on-wing cleaning of an aero-engine of the same model in different use states, the technical problem that on-wing cleaning equipment of the engines is poor in compatibility is solved, and very small deformation caused by long-term use of air inlet lips of the engines is compensated; very small fitting gaps of the aero-engines in later use of the wing washing rack can be better made up, and reference is provided for improving the washing technology and scientific washing plan arrangement is performed.

Description

technical field [0001] The invention belongs to the technical field of aero-engine cleaning, in particular to an adjustable and fixed aero-engine on-wing water washing rack. Background technique [0002] Aeroengines are the key source of power for aircraft. Pollutants such as sand, dust, and flying insects in the air are fouled in the internal passages, which have a direct or indirect impact on the reliability and economy of the engine. The use experience of military and civil aero-engines at home and abroad shows that in-wing water washing of aero-engines is an important technical means to slow down its performance decline, prolong its full life cycle, and reduce fuel consumption. Due to the fact that the engine does not need to disassemble the engine blades during the cleaning process and is carried out in a cold running state, it can effectively improve engine propulsion efficiency and reduce operating costs. It has been included in aircraft maintenance as a basic procedu...
