Abstract
Description
Technical Field
[0001] This utility model relates to the field of aircraft maintenance technology, and in particular to an aircraft control surface angle measuring ruler. Background Technology
[0002] In the field of aircraft maintenance, the deflection angle of control surfaces (such as ailerons, elevators, and rudders) directly affects flight safety and handling performance.
[0003] Traditional measurement methods often use laser measuring instruments. Although they are fast, they are not portable, and the equipment is large and heavy (usually ≥3kg). They need to be transported in special protective cases and are difficult to adapt to confined spaces or high-altitude operations. They rely on electricity and require continuous power supply (battery or external power source). Their battery life is insufficient in extreme environments (such as high altitudes or deserts). They are also susceptible to interference from strong light and vibration, which can cause data fluctuations or calibration failures. Utility Model Content
[0004] To address the issues of poor portability, reliance on power, and susceptibility to environmental factors when maintenance personnel use laser measuring instruments to measure aircraft control surfaces, this application provides an aircraft control surface angle measuring ruler.
[0005] The aircraft control surface angle measuring ruler provided in this application adopts the following technical solution:
[0006] An aircraft control surface angle measuring ruler includes a measuring ruler body, which includes a vertical side, a horizontal side, a first inclined side, and a second inclined side. The vertical side and the second inclined side are located on opposite sides of the measuring ruler body. The horizontal side is located between the vertical side and the second inclined side and at the bottom of the measuring ruler body. The first inclined side is located between the vertical side and the second inclined side and at the top of the measuring ruler body. An angle ruler, which is an arc-shaped plate, is integrally formed on the measuring ruler body and is located between the first inclined side and the second inclined side. The angle ruler has graduations. A protrusion is integrally formed on the measuring ruler body and is located between the vertical side and the second inclined side.
[0007] Preferably, the measuring ruler body has a through groove that extends through both surfaces of the measuring ruler body.
[0008] In summary, this application includes the following beneficial technical effects:
[0009] This utility model provides an aircraft control surface angle measuring ruler. During operation, simply attach the measuring ruler tightly to the elevator so that the protrusion on the measuring ruler body is inserted into the groove of the elevator to measure the deflection angle of the adjustment tab (TAB). The operation is simple and easy to carry, thus improving the problems of poor portability, reliance on power, and environmental influence when maintenance personnel use laser measuring instruments to measure aircraft control surfaces.
