Embodiment Construction

[0092] The present invention will be further described below in conjunction with specific examples.

[0093] See Figure 1-13 , in the first preferred embodiment of the present invention, a fastening structure of a fighter cockpit transparent part of the present invention includes a body 1 and a cockpit transparent part 2 installed on the body 1; the periphery of the cockpit transparent part 2 is combined with a border 3 . An installation structure matching the body 1 is formed on the frame 3. The frame 3 includes a pressing component 31 and a fastening component 32. The pressing component 31 and the cabin transparent part 2 press the fastening component 32 to generate prestress and then fasten the cabin transparent part 2. . Among them, the fighter can adopt such as figure 1 Shown adopts the structure of whole cockpit transparent part 2; Also can adopt as Figure 8 Shown adopts the structure of multi-piece cockpit transparent part 2. see Figure 14-17 , for the convenie...

Abstract

A fastening structure for a transparent member of a fighter plane cockpit and a fastening method therefor. The fastening structure comprises an aircraft body (1) and a cockpit transparent member (2) installed thereupon; the periphery of the cockpit transparent member (2) is fitted with an edge frame (3), said edge frame (3) comprising a compression component (31) and a fastening component (32). The combined pressure on the fastening component (32) of the compression component (31) matched to the cockpit transparent member (2) creates a prestressing force which serves to fasten the cockpit transparent member (2). The present fastening structure is very strong, and has a wide range of application.

Description

technical field [0001] The invention relates to military aircraft such as various fighter jets in the field of national defense construction, in particular to a fastening installation structure and a fastening method for a transparent part of a fighter cockpit. Background technique [0002] The transparent parts of the fighter cockpit generally include the fixed windshield transparent part and the movable canopy transparent part. At present, the integral canopy that combines the two is not uncommon. Under the current situation, military aircraft has become an important manifestation of a country's military strength, and the transparent cockpit as an important optical structural part on a fighter must have the following functions: firstly, it is called a structural part, and must have sufficient strength. To withstand the cockpit pressure of fighter jets, aerodynamic loads, body structure loads and bird impact loads, etc.; the second is that as a transparent observation windo...
