Description

TECHNICAL FIELD

[0001] The utility model relates to the field of aerospace and aviation, in particular to general aircraft. BACKGROUND

[0002] The general aircraft is provided with a luggage compartment, which is a fuselage space for placing luggage. SUMMARY

[0003] The utility model solves the technical problem of how to facilitate the fixing and installation of the luggage compartment on the fuselage.

[0004] To solve the above technical problem, the utility model provides the following technical scheme: a general aircraft composite material luggage compartment, which comprises a cabin body and a fixed edge, the cabin body and the fixed edge are integrally formed, the fixed edge is fixedly connected with the fuselage, the fixed edge is located at the front end of the cabin body, the outer diameter of the fixed edge is larger than that of the cabin body, a plurality of embedded fixing rings are arranged on the fixed edge and are distributed in the circumferential direction of the fixed edge, and the connecting pieces matched in the fixing rings are used to fix and install the fixed edge on the fuselage.

[0005] The outer periphery of the fixed edge is matched with a rubber lining, which can not only protect the fixed edge but also make the fixed edge and the fuselage stably fit when the fixed edge is pressed on the fuselage by the connecting pieces, thereby facilitating the stability of the luggage compartment.

[0006] A reserved recess structure is arranged on the cabin body and extends forward to the fixed edge. The reserved recess structure leaves space for the installation of an air conditioner.

[0007] A ventilation hole is arranged on the side wall of the cabin body, and an insect screen is arranged in the ventilation hole.

[0008] A reserved maintenance opening is arranged on the side wall of the cabin body, and a detachable maintenance opening cover plate is matched with the reserved maintenance opening. As an option, the maintenance opening cover plate is detachably connected with the cabin body through a threaded connecting piece.

[0009] A copper foil adhesive tape is attached to the outer bottom surface of the reserved maintenance opening, the copper foil adhesive tape is located on the outer wall of the cabin body and surrounds the reserved maintenance opening. A copper foil adhesive tape is attached to the bottom surface of the maintenance opening cover plate, and the copper foil adhesive tape faces the outside of the reserved maintenance opening. The copper foil adhesive tape has the function of signal removal and lightning protection.

[0010] As an improvement, the cabin body is provided with an extended cabin extending rearward. The outer diameter of the extended cabin is smaller than that of the cabin body, a step is formed between the extended cabin and the cabin body, and the ventilation hole is arranged on the step. The extended cabin increases the space of the luggage compartment and facilitates the placement of more luggage.

[0011] As an improvement, the luggage compartment comprises, from inside to outside, a glass fiber layer, a hybrid fiber layer, a foam sandwich layer, and a carbon fiber layer, that is, each side wall of the luggage compartment comprises, from inside to outside, a glass fiber layer, a hybrid fiber layer, a foam sandwich layer, and a carbon fiber layer in sequence. Specifically, the luggage compartment comprises, from inside to outside, one glass fiber layer, one hybrid fiber layer, three foam sandwich layers, and two carbon fiber layers.

[0012] The luggage compartment of the utility model is not only convenient for installation, but also convenient for installation of an air conditioner. The multilayer structure of the luggage compartment itself can improve its rigidity and tensile strength. BRIEF DESCRIPTION OF DRAWINGS
