Embodiment Construction

[0024] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0025] This patent provides a highly reliable and lightweight drag parachute connection device, which mainly solves the problem of direct transmission of variable concentrated force and instantaneous separation, and ensures that forced separation can be achieved when the concentrated force is too large. The device requires simplicity, reliability and light weight.

[0026] The patented invention mainly includes a short frame 1, a resistance parachute joint 2, a fixed parachute throwing assembly 3, and the fixed parachute throwing assembly 3 is composed of a U-shaped ring 6, a racer bearing 10, a journal 5, a lock nut 8, a parachute throwing fire Artifact 9 and main umbrella connecting pin 11 form. Its working principle is: the concentrated force of the main parachute is transmitted to the drag parachute joint 2 through the main parachute connect...

Abstract

The invention relates to the technical field of drag parachute mechanisms, in particular to a high-reliability lightweight drag parachute connecting device. The high-reliability lightweight drag parachute connecting device comprises a short frame, a drag parachute joint and a fixed parachute jettison assembly, wherein the short frame is of a rectangular structure; the drag parachute joint is of an open-side triangular structure; the two ends of the drag parachute joint are fixedly installed at the two ends of the short frame correspondingly; a through hole is formed in the top of the drag parachute joint; the fixed parachute jettison assembly is fixedly installed in the through hole of the drag parachute joint; a main parachute connecting band is arranged at one end of a main bearing beam of an external machine body for fixed connection, a main parachute connecting pin penetrates through a through hole in the main parachute connecting band, and through vertical locking of a split cotter, fixed connection of the fixed parachute jettison assembly and the main bearing beam of the external machine body is achieved. The high-reliability lightweight drag parachute connecting device achieves direct transfer and instant separation of variable concentrated force and can ensure the effect that forcible separation can be achieved when the concentrated force is too high, and according to the requirements, the device is easy and convenient to use, reliable and low in weight.

Description

technical field [0001] The invention relates to the technical field of a drag parachute mechanism, in particular to a highly reliable and lightweight drag parachute connecting device. Background technique [0002] The drag parachute is also called a drogue parachute, and it is usually composed of a main parachute, a guide parachute, a parachute cover and a connecting device. Its function is to decelerate the aircraft by increasing the aerodynamic resistance of the aircraft when it lands. When landing, the aircraft opens the parachute hatch, the pilot parachute falls out first, and the parachute cover is pulled out under the action of the airflow, so that the main parachute is gradually opened, and aerodynamic resistance is generated to slow down the aircraft. After reaching a certain speed, in order to avoid the friction of the canopy on the ground and avoid the influence of the aircraft being dragged twice under the condition of strong wind, the drag parachute needs to be t...
