Abstract

The invention belongs to the technical field of aircraft maintenance and measurement tools, and particularly discloses a universal fixed-wing aircraft control surface deflection angle detection device which comprises an elastic clamping device, the elastic clamping device comprises an upper clamping plate and a lower clamping plate, an upper clamping plate is arranged on the lower portion of the upper clamping plate, a lower clamping plate is arranged on the upper portion of the lower clamping plate, and the upper clamping plate and the lower clamping plate are arranged in an axial symmetry mode. A horizontal sliding rod is vertically and slidably connected to the upper clamping plate, a fixing part used for fixing the sliding rod is arranged on the upper portion of the sliding rod, a horizontal round rod is arranged on the side, away from the upper clamping plate, of the lower portion of the sliding rod, a flat plate is rotatably connected to the side, away from the sliding rod, of the round rod in the axial direction, and a protractor is coaxially and rotatably connected to the side, close to the sliding rod, of the round rod. The protractor comprises an arc-shaped angle plate, the axis of the angle plate coincides with the axis of the round rod, and a gradienter is arranged on the angle plate. The universal fixed-wing aircraft control surface deflection angle detection device is mainly applied to the measurement of the deflection angle of an elevator or an aileron of an airplane, and solves the problems that an angle measuring instrument used in the prior art is tedious to operate and takes a long time in the use process.

Description

technical field [0001] The invention belongs to the technical field of aircraft maintenance measurement tools, and specifically discloses a general-purpose fixed-wing aircraft control surface deflection angle detection device. Background technique [0002] A soft control system is used on a certain type of aircraft. These control cables are made of stainless steel wires. The advantages of stainless steel cables are strong corrosion resistance, but the disadvantage is poor wear resistance. In recent years, with the increase of flight time, the phenomenon of broken wires of the control cables has occurred many times, and even the entire cable has broken. In order to prevent the occurrence of faults, it is necessary to increase the inspection frequency of the control cables. Every time after replacing the broken wire rope or adjusting the tension in different seasons, you must check and adjust the deflection angle of the rudder surface to ensure that the deflection angle is wit...
