Example Embodiment

[0016] The present invention will be further described in detail below through specific embodiments:

[0017] See also figure 1 with figure 2 ,among them, figure 1 It is a schematic diagram of the structure of the test loading device for the control system of the aircraft control stick of the present invention. figure 2 It is a schematic diagram of its principle. In this embodiment, the test loading device of the aircraft control lever control system includes a sliding rail 1, a sliding surface 2, a double-acting ball 3, a dummy control lever 4, a hydraulic actuator 5, and a frame 6 containing a sliding surface 2.

[0018] Wherein, the slide rail 1 is a horizontal slide rail, including a heading slide rail and a side slide rail. The heading slide rail and the direction-finding slide rail are arranged on the upper and lower levels, not in the same plane, and they are connected end to end. Form a rectangular box. See also image 3 It is a structural diagram of the sliding rail 1. ...

Abstract

The invention relates to a loading device, in particular relating to a test loading device of an airplane joystick type control system. The test loading device of the airplane joystick type control system provided by the invention comprises a slide rail, slide surfaces, double acting balls, a false joystick and frames comprising the slide surfaces, wherein the slide rail is a horizontal slide rail and comprises a heading slide rail and a lateral slide rail; the heading slide rail and the lateral slide rail are respectively arranged on upper and lower layers, and the heading slide rail and the lateral slide rail are connected end to end; the slide surfaces are elongated slot slide surfaces which are arranged in the frames; the number of the frames is two, and the two ends of each frame are arranged in the slide rail; and the double acting balls are arranged in the slide surfaces, and the centers of the double acting balls pass through the false joystick. The test loading device provided by the invention can be used for finishing the tests of displacement follow-up loading and composite operation loads, thereby more truly simulating the service condition of a joystick, and having greater actual application value.

Description

technical field [0001] The invention relates to a loading device, in particular to a test loading device related to an aircraft control stick type control system. Background technique [0002] Usually, the static and fatigue tests of the aircraft control system are basically a ground strength verification test that is independent of the aircraft body structure and is also very important and directly related to flight safety. [0003] In the past, the control system test was generally a single independent operation test, that is, the respective tests of the steering system of the elevator (or full-motion horizontal tail), aileron, rudder and other control systems. The maneuvering flight of the aircraft (especially fighter jets) reflects that the operation of the control system is often a composite operation. Therefore, a test with both a single operating load and a compound operating load can better reflect the actual operation, and a device is needed to complete this task. ...
