Problems solved by technology

[0003] However, there is no suitable method in the prior art for the inspection of a huge structure like an airplane, and the method mainly uses manual ultrasonic inspection equipment such as visual inspection and palpation, or liquid immersion inspection and manual scanning.
Any of these methods is inefficient and relies on the feeling of skilled workers in many cases, resulting in problems of low work efficiency and low inspection accuracy.
With these conventional inspection methods, it is difficult to obtain objective data that can analyze and evaluate the history after participating in the voyage, and there is also a problem of quality assurance
[0004] In addition, a part of the prior art implements X-ray body non-destructive inspection, and the X-ray method requires a shielding structure that is not irradiated with radiation, so there is a small body that is limited to jet aircraft and the like, and can only be Issues with conducting inspections at restricted locations

no. 1 Embodiment approach

[0021] The inspection apparatus of an aircraft body according to this embodiment has an inspection vehicle equipped with a laser system, a 6-axis manipulator robot that holds an ultrasonic line array probe, an elevating mechanism that moves the robot in a vertical direction, and a robot that With a horizontal movement mechanism that moves in the horizontal direction, the inspection vehicle can move in front, back, left, and right directions and can freely approach (access) the aircraft body. The inspection vehicle is positioned relative to the aircraft body by means of a laser system. The actions of the above-mentioned robot, the lifting mechanism and the horizontal movement mechanism are controlled by the control device through a wireless remote (remote) transmission system. The ultrasonic waveform data obtained from the ultrasonic line array detector is transmitted to the control device through the wireless remote transmission system, and the calculation is performed accordi...

no. 2 Embodiment approach

[0037] 2nd Embodiment is demonstrated using FIGS. 7-9. Figure 7(a) is a plan view of an embodiment in which two trolleys 11 are arranged side by side and mounted on a horizontally movable horizontal movement mechanism 40, and a laser system and an ultrasonic detector are mounted, and Figure 7(b) is Figure 7(a) side view.

[0038] In addition, since the ultrasonic non-destructive inspection device for an aircraft body according to claim 2 can connect a plurality of vehicles through the horizontal movement mechanism corresponding to the inspection area of ​​the aircraft body, it can efficiently obtain more The advantages of a wide range of inspection data can greatly improve the efficiency of inspection operations.

[0039] 8 and 9 show the configuration using two or four inspection vehicles 10 shown in FIG. 7 . According to this configuration, inspection can be performed at multiple locations while improving inspection efficiency, so the overall inspection time can be shortene...

Abstract

The invention provides a detecting method for airframe and a device thereof which can correctly and high efficiently execute non-destructive inspection for the airframe instead of naked eye inspection and palpation. The device is comprised by: an inspection vehicle 10 capable of moving toward various direction; a laser emitter 32 carried by the inspection vehicle 10 and for irradiating the airframe 1 to be inspected and receiving the reflected laser; a supersonic detector 13 carried by the inspection vehicle 10 and for irradiating the airframe 1 to be inspected and receiving the reflected supersonic; a control device 35 for control the motion of the inspection vehicle 10 according to the signal transmitted form the laser emitter 32, and displaying the supersonic inspection data about the airframe according to the signal comes from the supersonic detector 13.

Description

technical field [0001] The invention relates to an inspection method and device for an aircraft body, which performs non-destructive inspection on the surface of the aircraft body not only in the manufacturing stage of the aircraft but also after entering into the flight operation. Background technique [0002] In the past, aircraft bodies were mainly composed of metal materials mainly composed of duralumin and aluminum alloys or their composite materials. However, recently, from the perspective of flight economy and environmental pollution countermeasures, CFRP (carbon fiber composites) has been adopted in order to further reduce the weight of the airframe. reinforced plastic) material. Generally, the strength characteristics of the CFRP material itself are sufficient as the flight performance, but it is often checked in advance whether there is aging deterioration after participating in the voyage, environmental degradation, or abnormal bonding between CFRP layers caused b...
