Embodiment Construction

[0021] In order to make the purpose, technical solution and advantages of the application more clear, the technical solution in the embodiment of the application will be described in more detail below in conjunction with the drawings in the embodiment of the application.

[0022] A loading device for an external hang test of an aircraft, comprising an external hang mechanism and a loading mechanism. The external hanging mechanism is used to connect the aircraft body structure, and the loading mechanism is used to connect the test loading equipment. The joints and holes on the loading mechanism are used as test loading parts, and the number and direction are determined according to the characteristics of the test load. Usually, three vertical, two lateral, and one longitudinal loading interfaces and holes are set on the loading mechanism.

[0023] According to the test loading space and the size of the equipment, determine the minimum distance between the joints and the holes o...

Abstract

The invention relates to the field of airplane strength structure tests, in particular to an airplane external hanging test loading device which comprises a plug-in mechanism and two loading mechanisms, the plug-in mechanism comprises a plug-in part and a connector part, and the two loading mechanisms are symmetrically connected to the two sides of the plug-in part. The loading mechanism is provided with a connecting part connected with the external hanging part, a vertical loading plate and a lateral loading plate, the vertical loading plate is provided with at least one group of vertical loading holes for vertical loading, and the lateral loading plate is provided with at least one group of lateral loading holes for lateral loading; and the external hanging part is provided with at least one group of course loading pieces for course loading. The device has the technical effects of effectively reducing the plug-in related difficulty and improving the test efficiency.

Description

technical field [0001] The application belongs to the field of aircraft strength structure tests, and in particular relates to a loading device for aircraft external hanging tests. Background technique [0002] In the structural strength tests of full-scale aircraft such as fighter jets and transport aircraft, the external cockpit test is one of the typical test conditions. The structural strength of the connection area between the cockpit and the aircraft fuselage or wing is assessed, and the cockpit is used as a test loading dummy. External hanging test loads usually include heading, vertical, side loads and pitch, roll, and yaw moments. To ensure load application, at least six loading points need to be set. [0003] Usually, the external dummy parts on the aircraft have different forms and complex structures. After the external test load processing is completed, the loads of each loading point are large and the distances are close, making it difficult to carry out the tes...
