Abstract
Description
Technical Field
[0001] This application belongs to the technical field of aircraft spoiler opening and retraction movement inspection test technology, specifically relating to an aircraft spoiler opening and retraction movement inspection test device. Background Technology
[0002] The aircraft spoiler has two fork-shaped control joints in the middle and single-ear suspension joints at both ends. The single-ear suspension joints at both ends are hinged to the wing via pins. The supporting ends of the two fork-shaped control joints are also hinged to the wing via pins. The hinged ends are hinged to the spoiler control mechanism on the wing via pins. The pilot drives the spoiler to deflect through the spoiler control mechanism, causing the spoiler to open and close, thereby increasing wing drag and reducing lift, thus achieving the purpose of deceleration and controlling the aircraft's attitude. It is an important component related to aircraft flight safety. Conducting retraction and retrieval operation inspection tests to verify whether the joints will jam and whether the spoiler will deform after repeated retraction and retrieval is of great significance.
[0003] Currently, most tests on the opening and retraction of aircraft spoilers use the spoiler control mechanism on real aircraft to open and retract the spoilers. This mechanism is complex, inconvenient to install, occupies a lot of space, and has high testing costs.
[0004] This application is made in view of the aforementioned technical deficiencies.
[0005] It should be noted that the above background information is only used to assist in understanding the inventive concept and technical solution of this invention, and it does not necessarily belong to the prior art of this application. In the absence of clear evidence that the above information was disclosed on the filing date of this application, the above background information should not be used to evaluate the novelty and inventiveness of this application.
