Description
Technical Field
The invention relates to the field of aircraft engine inspection, in particular to an aircraft engine blade integrity condition inspection system and an aircraft engine blade integrity condition inspection method.
Background
Modern airplanes are complex in structure and frequent in use, and the flight safety of the modern airplanes is influenced by various factors, such as damage to internal structures of airplane engine blades caused by too high rotating speed and too high temperature; or because of foreign objects such as: the impact of stones, gravel, metal objects, birds and the like causes damage to the external structure, so that cracks, chipping and the like occur. After the engine blades are damaged, the power of the engine is reduced, the thrust or the pull of the engine is further influenced, the airplane enters an unsafe state, the completion of a flight task is slightly influenced, and the safety of the airplane and drivers and passengers is even endangered in severe cases.
Therefore, in the maintenance and inspection work of the aircraft, great importance is placed on whether the engine blade is damaged or not and on the evaluation and inspection of the damage condition, and the clear and specific requirements are placed on the work in the military and civil aviation aircraft maintenance regulation. However, in the maintenance practice of aircraft engines, the inspection work of the integrity of engine blades of some models is limited by the internal space of the aircraft and the engines, personnel cannot or have difficulty in approaching to perform visual inspection, and the inspection work can be completed only by means of professional equipment. The existing professional inspection equipment is an endoscope (a hole detector), a camera is installed on the endoscope, the camera can enter the engine through a special window to inspect blades, but the inspection range of the camera is small, so that the efficiency is low, the inspection equipment is only suitable for inspecting local and key parts, and the inspection equipment is not suitable for inspecting the blades of large-range and general parts, such as partial turbojet, the air inlet of a turbofan engine and the integrity of the blades at an air outlet.
The previous inspection work of relevant parts is completed manually, and the specific method comprises the following steps: the inspection personnel carry lighting apparatus to bore and carry out visual inspection in engine intake duct or the spray tube, because engine intake duct or spray tube inner space are narrower, the inspection work receives the limitation more, has influenced the inspection quality of blade to a certain extent, mainly concentrates on following three aspect: firstly, the inspector can only take a fixed posture and cannot change the angle to observe the intact condition of the blade, so that a certain inspection blind area is formed; and secondly, the inspection cannot be carried out or the inspection quality is reduced under the extremely severe environmental conditions. For example, when an airplane just lands, the temperature in an air inlet and a nozzle is high, and inspectors cannot enter the air inlet and the nozzle to inspect blades in a period of time, so that the time for preparing for next-time motor service is increased; the environment temperature is low in winter, the dressing of inspectors is thin, the body heat loss is fast, the work is difficult to last, and the inspection quality is influenced to a certain extent; and thirdly, part of inspection personnel with fat body types cannot drill into the air inlet channel or the spray pipe to complete the blade inspection work, only can search people for inspection instead, and objectively cause the inspection quality to be reduced. Therefore, the method for checking the integrity of the blades of the aircraft engine, which can guarantee the quality to the maximum extent, is fast and efficient, and a set of system for checking the integrity of the blades is constructed urgently.
