Abstract

The invention belongs to the technical field of airplane strength tests, in particular to a central wing test supporting device comprising bottom beams (1), press beams (2) and posts (8), which are welded to form an integral structure. One ends of acting tubes (3) are connected to the bottom beams (1), and the other ends are connected to loading cases (4); the loading cases (4) comprise ribs (13), wall boards (14) and beams (15) which are fixedly connected through bolts; the loading case segments (4) and external wing dummy parts (6) are connected through corner cases (5) of the loading case segments (4); the external wing dummy parts (6) and test parts (7) are connected through supporting clamps including first supporting clamps (9), second supporting clamps (10), third supporting clamps (11) and fourth supporting clamps (12). The device is capable of testing a central wing independently and simulating an airplane body supporting the central wing and is simple in structure and low in cost.

Description

technical field [0001] The invention belongs to the technical field of aircraft strength tests, and in particular relates to a central wing test support device. Background technique [0002] During the aircraft manufacturing process, the central wing crosses the middle fuselage to connect the left and right outer wings into a whole. The main function of the central wing is to balance and transfer the load from the outer wings. When testing the central wing, in order to make the supporting simulation realistic and simple, a section of the fuselage is usually taken as the support. The connection joints and connection areas between the central wing and the outer wing are genuine, and the outer wing is a dummy. For the test piece with only the central wing, how to simulate the support of the fuselage to the central wing is the key point and difficulty of the test success or failure, and there is no relevant technical solution disclosed at home and abroad.
