Embodiment Construction

[0019] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated.

[0020] Such as Figure 1 to Figure 4 As shown, the emergency exit energy-gathering cutting method provided by the present invention comprises the following steps:

[0021] Step 1: Demarcate the pre-cut emergency exit shape on the fuselage skin 3 by cutting the predetermined route of the cable, and the fuselage skin 3 is also provided with a stringer 4 (here, the stringer 4 can also be a frame). Among them, the shape of the pre-cut emergency exit is usually a rectangle.

[0022] Step 2: Dividing the predetermined route of the cutting cable into a plurality of first cutting segments and a plurality of second cutting segments. Wherein, the first cutting section is the ...

Abstract

The invention relates to the technical field of aviation lifesaving, in particular to an energy-gathering cutting method for emergency exits to solve the problem of difficulty in arranging energy-gathering cutting cables. The emergency exit energy-gathering cutting method includes the following steps: dividing the pre-cut emergency exit shape; dividing the predetermined layout line of the cutting cable into a plurality of first cutting sections and a plurality of second cutting sections; A plurality of first energy-shaping cutting cables and a plurality of second energy-building cutting cables, each of the second energy-building cutting cables is also provided with a protective cover of energy-building cutting cables; The second energy-concentrating cutting cables are respectively arranged on the corresponding plurality of first cutting segments and the plurality of second cutting segments to perform energy-concentrating cutting. The energy-gathering cutting method for emergency exits of the present invention can more conveniently arrange and install the energy-gathering cutting cable, improves the manufacturability of installation on the aircraft, and also avoids the multiple bending of one energy-gathering cutting cable, which affects the reliability of the product. sex.

Description

technical field [0001] The invention relates to the technical field of aviation lifesaving, in particular to an energy-gathering cutting method for an emergency exit. Background technique [0002] At present, the use of energy-gathering cutting technology to form aircraft emergency exits has not been adopted in existing models. In the pre-research project, the formation of aircraft emergency exits by energy-gathering cutting technology has been studied and verified by principle tests. Due to the special long stringer-frame-skin structure of the aircraft fuselage, and cutting an emergency exit needs to span several long stringers or frames, an energy-concentrating cutting cable is arranged on the fuselage structure, which is very long and needs to go through many The secondary bending brings great difficulties to the arrangement of the energy-shaping cutting cables, and it is not easy to implement on the aircraft. Contents of the invention [0003] The purpose of the prese...
