The invention provides a control surface rotation angle test system. The system includes four control surface rotation angle test units, four vertical bases, four joint arms, an integrated cabinet anda piece of test system software. Each control surface rotation angle test unit includes three three-dimensional probes which are connected with the corresponding vertical base through the corresponding joint arm. The joint arms are used for driving the three-dimensional probes to rotate and adjusting the positions of the three-dimensional probes of the control surface rotation angle test units tomake a tested part placed within the measurement range of the control surface rotation angle test units. The control surface rotation angle test units project laser light spots to the tested surfaceof the tested part, image the light spots, analyze and calculate the position information of the light spots, convert the position information into an RS485 signal and output the RS485 signal. The control surface rotation angle test system provided by the embodiment of the invention can realize real-time dynamic measurement of the rotation angle of a control surface in a dynamic rotation state, soas to inspect the consistency between the actual rotation angle and the control signal issued by an integrated control computer and complete the function detection of the integrated control computer.
Description
technical field [0001] The invention relates to the technical field of test and measurement, in particular to a rudder surface rotation angle test system. Background technique [0002] As an important part of the aircraft, the control and navigation system mainly includes the integrated control computer, inertial measurement components and steering gear system, etc., and its performance indicators affect the overall performance of the aircraft. [0003] In the past, the test methods were designed and developed for each specific model, the functions were scattered, the test was relatively independent, and the test efficiency was low. At the same time as the development of new models, necessary test methods must be developed to meet the test requirements. Contents of the invention [0004] In order to solve the problem that the current test method is single and the test is complicated, the present invention provides a test method for the rudder surface rotation angle, which...
