Embodiment Construction

[0014] Referring to the accompanying drawings, the flap trailing edge measurement device in the embodiment is composed of a base 1, a rocker arm 2, a scale 3, a measurement pointer 4, a reference pointer 5, and a clip 7. See figure 1 . The lower end of the rocker arm 2 is connected to the base 1, and the scale 3 is fixed on the upper end of the rocker arm 2. Pointer guide rails 10 are provided on both sides of the scale 3. The pointer includes a reference pointer 5 and a measurement pointer 4. The reference pointer 5 passes through the A backup bolt is fixed on the guide rail 10 on one side of the scale, and the measurement pointer 4 is fixed on the guide rail 10 on the other side of the scale through the backup bolt. The body of the measurement pointer 4 is a connecting block 8, and there is a A vertical tapered chute 9 with a narrow top and a wide bottom. There is a slider 12 on the body of the clip 7 , and the slider 12 is embedded in the tapered chute of the connecting blo...

Abstract

A method for measuring the swing error of the trailing edge of an aircraft flap. There is a measuring device. The measuring device is composed of a base, a rocker arm, a scale, a pointer and a clip. The clip of the measuring device is clamped on the trailing edge of the flap to ensure The swing direction of the trailing edge of the flap is consistent with the direction of the scale on the scale. Align the reference pointer with the measuring pointer, apply an upward force to the trailing edge of the flap, drive the clip and the measuring pointer to move upward along the scale, and fix the measuring pointer and the measuring pointer. Finally, by calculating the difference between the reference pointer and the measurement pointer, the maximum swing of the trailing edge of the flap can be obtained.

Description

technical field [0001] This application relates to the field of assembly of aircraft flap control systems, in particular to a method and a device for accurately measuring the swing amount of the flap trailing edge in the simplest way. Background technique [0002] After the assembly of the aircraft flap control system is completed, the flap actuator screw coupler, sliding frame and slide rail will cause the movable gap of the flap due to the assembly error. It is required that when the flap is in any position, the up and down swing of its trailing edge under the action of external force shall not exceed a fixed value, such as 5mm. If this fixed value is exceeded, it will bring safety hazards, especially when the flap swing clearance on one side is out of tolerance, resulting in a large difference in flap swing clearance on both sides, which will affect flight safety. Therefore, the flap swing clearance must be adjusted. Measurement. [0003] There is currently no special t...
