Embodiment Construction

[0016] Referring to the accompanying drawings, the present embodiment is a schematic diagram of a method for installing a mooring structure on an aircraft composite floor. Bolts 11 can fix the mooring ring seat 1 with the composite material floor 2 , the longitudinal reinforcement 6 , the transverse reinforcement 5 and the reinforcement corner box 7 through the bracket nut 10 .

[0017] The composite material floor 2 is provided with an installation through hole 3. In order to protect the floor and enhance the strength of the installation through hole, it is best to protect and strengthen the installation hole during implementation. In this application, a protective hole bushing 4 is installed in the installation hole. In order to make the grommet liner fit closely with the mounting hole, epoxy sealant is coated around the mounting hole and bonded to the grommet liner 4 . Hole guard bushing 4 is respectively one up and down, supporting use.

[0018] In order to increase the s...

Abstract

The invention discloses a method for mounting a mooring structure on a composite-material floor of an aeroplane. The method comprises an annular mooring base, a longitudinal stiffener, a transverse stiffener, a reinforcing angle box, a supporting stand column and a composite-material floor, wherein the longitudinal stiffener, the transverse stiffener, the reinforcing angle box and the supporting stand column are mutually and fixedly connected into a whole; mounting holes for the annular mooring base are manufactured in the composite-material floor, and the mounting holes for the annular mooring base are overlapped with fixing holes in the annular mooring base; mounting holes in the composite-material floor are overlapped with connection through holes which are formed in the superimposed positions of the longitudinal stiffener, the transverse stiffener and the top of the reinforcing angle box; the annular mooring base is connected and fixed to the composite-material floor, the longitudinal stiffener, the transverse stiffener and the reinforcing angle box through bolts and anchor nuts.

Description

technical field [0001] The invention relates to the technical field of aircraft structure design, in particular to a method for installing a mooring structure on an aircraft composite material floor. Background technique [0002] Frames 7 to 11 of a certain type of aircraft are the cargo compartment area of ​​the aircraft, which is used to store luggage and articles carried by passengers. There is a tethered ring seat installed on the floor of the cargo compartment, and the nylon belt is connected to the tethered ring seat on the floor to secure the cargo to the floor to prevent the aircraft from changing its flight attitude during takeoff, landing or flight. Goods move in all directions. [0003] Since the cargo will move during the flight of the aircraft, the cargo will impact the structure at the mooring ring seat and form an impact force. This requires rearranging and strengthening the structure at the installation of the mooring ring seat to transfer the cargo The imp...
