Maintaining clamp for jet braking C duct of civil aviation passenger plane

Abstract

The invention discloses a maintaining clamp for jet braking C duct of a civil aviation passenger plane. The clamp comprises a horizontal tray, a support track arranged on the tray, at least three locking clamps arranged on the tray, at least three columns and upper locking clamps correspondingly located on the columns. The support track is circular and is matched with the shape of a torsion box V-shaped groove of the jet braking C duct to support the torsion box V-shaped groove on the top face of the support track. The columns are located on the periphery of the support track and distributed along the circle to form a working space in enclosing mode used for vertically placing the jet braking C duct. A clamp opening of the upper locking clamp faces downwards and is used for clamping the back end of the noise reduction inner wall of the jet braking C duct, and a clamping opening of the lower locking clamp faces upwards and is used for clamping the front end of the noise reduction outer wall of the jet braking C duct to fix the jet braking C duct. By means of the maintaining clamp, the jet braking C duct can be well fixed to be maintained. The clamp prevents parts of the jet braking C duct from being deformed and cannot affect plane aerodynamics performance of the jet braking C duct.

Description

technical field [0001] The invention belongs to the technical field of aircraft maintenance, and in particular relates to a repair fixture for a reverse thrust C duct of a civil aviation airliner, and is particularly suitable for overhauling the reverse thrust C duct of a 737 type civil aviation airliner. Background technique [0002] The thrust reverser system of a civil aviation airliner is used to change the exhaust direction of the engine fan (forward) to generate reverse thrust, which helps to reduce the speed of the aircraft when the aircraft lands normally or when the takeoff is interrupted in an emergency. Such as figure 1 As shown, the thrust reverser system of the 737 civil aviation airliner is mainly composed of a translation cover (not shown in the figure) and a thrust reverser C duct. The translation cover can be detachably installed on the thrust reverser C duct. Shaped sound-absorbing inner wall 1, front torsion box 2 located outside the sound-absorbing inner...

AI Technical Summary

Problems solved by technology

And when it is necessary to disassemble, repair or assemble the reverse thrust C duct, because the parts are mainly made of aluminum or composite materials, if there is no special clamp to fix them, it is easy to cause the components of the reverse thrust C duct deformation of
