Abstract

The invention discloses a full-aircraft drop test device and a full-aircraft drop test method and relates to the technical field of aircraft drop test. The full-aircraft drop test device comprises a support structure which is used for supporting a full-aircraft test model; an elevating system which is fixed on the support structure and is connected with the full-aircraft test model and is used for lifting or dropping the full-aircraft test model; a force measurement platform which is fixed on a test ground and is arranged in accordance with a landing gear of the full-aircraft test model and is used for supporting the dropped full-aircraft test model. According to the full-aircraft drop test method, the drop test of a full-aircraft test model is completed by means of the above full-aircraft drop test device. The invention is advantageous in that the invention can quickly adjust the attitude of the full-aircraft test model, has simple structure and low manufacturing cost, and can be applied to different types of full-aircraft test models.

Description

technical field [0001] The invention relates to the technical field of aircraft drop tests, in particular to a whole-aircraft drop-shock test device and a whole-aircraft drop-shock test method. Background technique [0002] In the whole aircraft drop test, the attitude of the aircraft needs to be adjusted several times for different test conditions. In order to meet the installation requirements of different attitude angles of the aircraft, it is necessary to complete the design of the landing gear installation fixture according to the size of the test model in the current domestic and foreign tests, so that it can simulate the test requirements of the landing gear of the aircraft at different attitude angles. [0003] This test method has the following characteristics: First, the workload of this method is extremely large, and the fixture needs to be precisely designed during the test design stage, which increases the design workload; secondly, it is necessary to check the ...
