Problems solved by technology
This method is more suitable for small aircraft, but for large aircraft, after the aircraft is off the shelf, the water rudder height is relatively high, and the method of passing the plumb line is not easy to implement, and the aircraft needs to be leveled and measured without allowing the aircraft to perform other tasks. affect the measurement results

Embodiment Construction
[0024] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0025] like figure 1 ,to Figure 4 As shown, a water rudder deflection angle measuring device includes a fixing mechanism 1, an RVDT sensor 2, a rotating table 4, an adapter 5, 8 balancing balls 6, two guiding mechanisms a8, two guiding mechanisms b9, and a fixed The rod 10; the adapter 5 is equidistantly and spaced from the guide mechanism a8 and the guide mechanism b9. The rotating table 4 and the adapter 5 are equidistantly separated by four balance balls 6; they are limited by the ring grooves of the guide mechanism 18 and the guide mechanism 29. The concave cavity at the bottom of the adapt...

The invention belongs to the field of aircraft system debugging, and relates to a water rudder deflection angle measuring device. The device comprises a fixing mechanism (1), an RVDT sensor (2), a rotary table (4), an adapter (5), eight balance balls (6), a guide mechanism a (8), a guide mechanism b (9) and a fixing rod (10). The deflection angle of a water rudder can be directly measured througha rotating shaft of the water rudder. The water rudder deflection angle measuring device is small in size and can be installed in a narrow space area in a cabin. Due to the fact that rotation of the rotating shaft is directly measured, the posture and vibration of an airplane do not influence a measuring result, and necessary preconditions for measurement are reduced. The device is simple and ingenious in structure, high in measurement accuracy and efficiency, low in manufacturing cost and easy to popularize and apply in various aircraft factories and maintenance units.
Description
technical field [0001] The invention relates to a water rudder deflection angle measuring device, which belongs to the field of aircraft system debugging and relates to a water rudder deflection angle measuring 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. After the water rudders and their control systems are installed, the deflection angle of the water rudders must be calibrated. Due to the long distance between the structures around the water rudder, there is no neutral point that can be used 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 deflection position at this time to the drawing board in the same way. Measure the distance between two points on the drawing boar...
