Mechanical performance test system for general-purpose plane

Abstract

The invention discloses a mechanical performance test system for a general-purpose plane. The mechanical performance test system includes an engine of the general-purpose plane, an engine torque loading device connected with a main landing gear, a front-end loading truss for supporting the engine torque loading device, an actuating cylinder for applying a load, a plane body loading device connected with the plane body of the general-purpose plane and used for transmitting the load applied by the actuating cylinder to the general-purpose plane, a tail supporting device connected with a horizontal tail of the general-purpose plane and a wing supporting device connected with a wing of the general-purpose plane. According to the mechanical performance test system for the general-purpose plane,the application of the full-plane load can be completed only by the adoption of the actuating cylinder, the number of purchased test room actuating cylinders and loading control channels is reduced,the test cost is obviously reduced, the investment of test human resources is saved without a complex adhesive tape sticking process, and the test period is shortened.

Description

technical field [0001] The invention belongs to the technical field of aviation aircraft testing, in particular, the invention relates to a general aircraft mechanical performance testing system. Background technique [0002] Existing general-purpose aircraft are loaded through pallets or adhesive tapes in the structural mechanical performance tests of the whole aircraft. Although the load distribution of the aircraft can be simulated more realistically, this test system is extremely complicated, and the design cycle is long and the construction cost is high. , It is necessary to build a complex truss system, design a multi-stage loading lever, and use multiple actuators to achieve multi-point uniform loading. The test process is complicated and cumbersome, and the test period is long. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. For this reason, the present invention provides a ki...
