Embodiment Construction
[0024] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.
[0025] like figure 1 ,to Figure 4 As shown, a water rudder declination angle measurement device includes a fixing mechanism 1, an RVDT sensor 2, a rotating table 4, an adapter 5, 8 balance balls 6, two guiding mechanisms a8, two guiding mechanisms b9, and a fixed The rod 10; the adapter 5 is connected with the guide mechanism a8 and the guide mechanism b9 at equal distances and intervals. The rotary table 4 and the adapter 5 are equidistantly separated by four balance balls 6; The concave cavity at the bottom of the adapter 5 is matched with the shape of the water rudder rotating shaft...

The water rudder deflection angle measuring device of the present invention belongs to the field of aircraft system debugging, and relates to a water rudder deflection angle measuring device; comprising a fixing mechanism (1), an RVDT sensor (2), a rotary table (4), an adapter (5), 8 balance balls (6), guide mechanism a (8), guide mechanism b (9), and fixed rod (10); the present invention can directly measure the deflection angle of the water rudder through the water rudder rotating shaft, and its volume is small, and can be installed in In the narrow space of the cabin, since the rotation of the rotating shaft is directly measured, the attitude and vibration of the aircraft will not affect the measurement results, thereby reducing the necessary preconditions for the measurement. The device has simple and ingenious structure, high measurement accuracy and efficiency, low manufacturing cost, and is easy to popularize and apply in various aircraft factories and maintenance units.
Description
technical field [0001] The invention relates to a water rudder declination angle measuring device, which belongs to the field of aircraft system debugging, and relates to a water rudder declination angle measurement device. Background technique [0002] At present, amphibious aircraft at home and abroad need to travel and turn on the water surface, so they are all designed with water rudders, and the water rudders and their control systems need to calibrate the deflection angle of the water rudders after installation. Because the structure around the rudder is far away, there is no neutral point as a reference for positioning. The usual method is to level the aircraft, lead the trailing edge point of the water rudder to a drawing board by means of a plumb line, rotate the water rudder to the limit, and then lead the declination position at this time to the drawing board in the same way. Measure the distance between two points on the drawing board to get the deflection angle...
