Problems solved by technology

[0002] The canopy and the fuselage of the current combat aircraft are separated. In an emergency, the canopy is thrown away to form an escape channel for the pilot to escape. However, with the use of stealth combat aircraft, the use of cockpit The cover and the fuselage are separated, the stealth effect is relatively poor, and the stealth performance and structural force transmission of combat aircraft cannot be effectively guaranteed

Embodiment

[0036] Such as figure 1 The shown escape canopy structure includes a hatch frame 1 with an integrated structure with the body, and the hatch frame 1 is an escape passage opened on the top of the body, and the escape passage is located in front of the driver in the body. At the same time, the edge of the escape channel extends vertically downwards to form a downward flange and then forms the hatch cover frame, which can ensure that the later separation bolt assembly 2 can be fixedly connected to the lower flange of the hatch cover frame, so as to facilitate the hatch The cover 5 is fixedly connected to the hatch cover frame through a separate bolt assembly 2, specifically, there are multiple separate bolt assemblies 2, which are evenly distributed on the flange of the hatch cover frame, so as to ensure the fixed connection of the hatch cover. When separating, the separation bolt assembly is separated at the same time; the hatch cover 5 that is sealed and connected to the hatch ...

Abstract

The invention belongs to the technical field of airplane protection lifesaving, and provides an escape canopy structure and a canopy separation bolt throwing method. The escape canopy structure comprises a hatch cover frame integrated with a machine body and a hatch cover connected to the hatch cover frame in a sealed mode, wherein the hatch cover is movably connected with the hatch cover frame through a rear hinge mechanism, a plurality of separation bolt assemblies for fixedly connecting the hatch cover with the hatch cover frame are arranged on the inner side surface of the hatch cover frame, and the separation bolt assemblies are automatically separated to separate the hatch cover and the hatch cover frame when an airplane encounters an emergency; and a throwing rocket for throwing thehatch cover separated from the hatch cover frame is fixedly arranged on the inner side surface, which is away from the rear hinge mechanism, of the hatch cover. By means of the impact force generatedafter the separation bolt assemblies explode, the cabin cover can be pushed to ascend, the canopy is facilitated to rotate, and interference with an airplane body is avoided; and the hatch cover canbe thrown more timely and quickly, and a safety guarantee is provided for pilots in the escape process.

Description

technical field [0001] The invention relates to the technical field of aviation protection and lifesaving, in particular to an escape canopy structure and a canopy separation bolt throwing method. Background technique [0002] The canopy and the fuselage of the current combat aircraft are separated. In an emergency, the canopy is thrown away to form an escape channel for the pilot to escape. However, with the use of stealth combat aircraft, the use of cockpit The cover is separated from the fuselage, and the stealth effect is relatively poor, which cannot effectively guarantee the stealth performance and structural force transmission of the combat aircraft. In order to achieve this purpose, the canopy and the fuselage are connected by a separate bolt assembly, which can ensure the airtight connection between the canopy and the fuselage, and at the same time, the separate bolt assembly can realize automatic separation. In the actual process, the canopy is The main problem to...
