Embodiment 1

[0054] This embodiment provides an aircraft (for example, titanium alloy aircraft) tail compartment, see figure 1 , comprising an engine 4, a framework sheathed outside the engine 4 and a skin sheathed outside the framework, the framework includes at least five support frames 1 coaxially arranged, empennage connecting columns 3 arranged on the outer peripheral surface of the support frame 1 and located at For the truss 2 between two adjacent support frames 1, except for a support frame 1 located at the rearmost end of the tail tank, the outer peripheral surfaces of the other support frames 1 are provided with empennage connecting columns 3, which are fixedly connected with the empennage, and the empennage The connecting column 3 is arranged obliquely relative to the vertical direction.

[0055] Compared with the prior art, in the aircraft tail compartment provided by this embodiment, the number of support frames 1 is at least 5, and except for a support frame 1 located at the ...

Embodiment 2

[0057] This embodiment provides a method for assembling an aircraft tail compartment, see figure 2 For the assembly of the aircraft tail compartment provided by embodiment one, the above-mentioned assembly method includes the following steps:

[0058] Step 1: Position the support frame on the assembly frame, and fix the truss between two adjacent support frames;

[0059] Step 2: Put the skin between the skeleton of the tail cabin of the aircraft and the assembly frame;

[0060] Step 3: The skin is fixedly connected (for example, riveted) to the skeleton of the aircraft tail compartment to form the aircraft tail compartment;

[0061] Step 4: Remove the tail cabin of the aircraft from the assembly frame, and perform finishing treatment on the connecting column of the tail.

[0062] In the prior art, the processing of the empennage connection column is usually before the assembly of the aircraft tail compartment, that is to say, the support frame has been processed before the ai...

Abstract

The invention discloses an aircraft stern compartment and an assembly method thereof, belongs to the field of aircraft assembly, and solves problems of low assembly precision of the aircraft stern compartment and unstable connection between the aircraft stern compartment and an empennage in the prior art. The tail cabin comprises an engine, a framework arranged on the outer side of the engine in asleeving mode and a skin arranged on the outer side of the framework in a sleeving mode, wherein the framework comprises at least five supporting frames which are coaxially arranged, besides the supporting frame located at the rearmost end of the tail cabin, tail wing connecting columns are arranged on the peripheral faces of the other supporting frames, and the tail wing connecting columns are fixedly connected with a tail wing. The assembling method comprises the steps that the supporting frame is positioned on the assembling jig; the skin is placed between the framework of the aircraft stern compartment and the assembly fixture; the skin is fixedly connected with a framework of the aircraft stern compartment to form the aircraft stern compartment; and the aircraft stern compartment isdetached from the assembly fixture, and the empennage connecting column is subjected to finish machining treatment. The aircraft stern compartment and the assembling method thereof can be used for assembling aircrafts.

Description

technical field [0001] The invention belongs to the field of aircraft assembly, and in particular relates to an aircraft tail compartment and an assembly method thereof. Background technique [0002] Aircraft assembly is the main link of aircraft manufacturing, and the effective control of assembly coordination accuracy is one of the key technologies in large aircraft manufacturing. The assembly coordination accuracy of the aircraft fuselage directly affects the overall shape and size matching performance, flight safety and structural fatigue life. The aircraft panel is the most basic typical structure in the fuselage structure, and its assembly accuracy directly affects the assembly quality of subsequent components and final assembly. [0003] The structure and coordination route of aircraft components are complex, and the quality of shape assembly is difficult to control. The traditional dimensional chain method mainly considers the rigidity deviation, and the accuracy i...
