Embodiment Construction

[0030] refer to Figure 1-7 . The aircraft rotary folding wing retractable detection device of the present invention comprises a movable outer wing shape-preserving frame 1, a movable working ladder 2, a wingtip folded in place detection platform 3, a central wing dummy, a laser tracker 7, a double row guide rail 8 and a three-coordinate Posture adjustment POGO columns9. The central wing dummy includes a middle and outer wing dummy 4 , a connecting piece 5 on the central wing dummy and a bracket 6 for the central wing dummy. The bottom of the central wing dummy bracket 6 is equipped with leveling anchor bolts 10, which simulate the space attitude of the central wing box, the middle and outer wings, and the fuselage, and serve as the main load-bearing structure of the wing; the three-coordinate attitude adjustment POGO columns 9 are placed in double rows On the guide rail 8, it is used to support the outer wing during transportation and attitude adjustment; and the movable wi...

Abstract

The invention discloses a detection device and method for folding and unfolding of a rotary folding wing of an airplane.The detection device and method are used for solving the technical problem of poor practicability of an existing detection device for folding and unfolding of a rotary folding wing of an airplane.According to the technical scheme, the detection device comprises a movable working ladder, a wingtip folding in-place detection table, a central wing false part, a laser tracker, double guide rails and three-coordinate posture adjusting POGO columns.The central wing false part comprises a middle-outer wing false part, a central wing false part upper connector and a central wing false part bracket.By means of the detection device and method, a planned folding path can be detected, the folding and unfolding properties of the folding wing can be accurately acquired, reliable data can be provided for design of a folding mechanism to serve as a practical design basis, and practicability is high, wherein the folding and unfolding properties include the wing surface appearance accuracy and jump in the unfolded state of the folding wing, the folding and unfolding stability, the multi-intersection point insertion and connection robustness, the wingtip in-place condition in the folded state and the like.

Description

technical field [0001] The invention relates to a detection device for retracting and deploying rotating folding wings of an aircraft, and also relates to a detection method for retracting and deploying rotating and folding wings of an aircraft. Background technique [0002] Rotary folding wing aircraft are widely used in shipboard equipment due to their small parking space. Due to the frequent times of wing folding and retracting, the strength requirements of the folding parts are extremely high, and the retractable space is limited. Therefore, it is necessary to detect and verify the performance of the wing folding path and the folding and retracting process. The folding wings are divided into outer wings and middle and outer wings. The middle and outer wings are connected and fixed with the central wing, and the outer wings can be rotated and folded through a specific mechanism.
