An electromechanical parachute opening mechanism

Abstract

The invention discloses an electromechanical parachute opening mechanism, which belongs to the field of model rockets. Mechanism of the present invention comprises electronic cabin, umbrella cabin, parachute. The electronic cabin includes a bulkhead for installing steering gear, an electronic cabin floor, an umbrella cover, a rocker arm and an electronic system; the rocker arm is connected by a small rocker arm and a large rocker arm through printed parts; the electronic system is composed of a barometer , single-chip microcomputer, step-down module, steering gear, etc.; the umbrella cabin is composed of laminates, spring barrels and springs; the spring is installed in the spring barrel and protrudes from the top plate; the two parachutes are stacked together In the umbrella cabin, one is hung on the small rocker arm through two metal rings, and the other is directly tied to the bottom of the umbrella cabin; thin carbon rods are added to the outside of the umbrella cabin and the electronic cabin, and covered with skin, so that The altitude measurement is accurate, and the thin carbon rods keep the shape of the rocket body, reducing the drag of the model rocket when it flies. The invention can reliably open the parachute at a specified height, and can separate the load from the parachute after returning to the ground.

Description

technical field [0001] The invention relates to the field of model rockets, in particular to the technical field of a highly reliable parachute opening mechanism. Background technique [0002] Nowadays, model rockets can be seen in various model airplane competitions and performances. In the prior art, the common ways to open the parachute of model rockets include gunpowder delayed explosion and purely mechanical parachute opening. These parachute opening methods have one or more of the following disadvantages: [0003] Said gunpowder delayed explosion and umbrella opening is easy to cause the umbrella cloth to burn because the temperature rises sharply when opening the umbrella, causing the rocket to crash. In addition, explosive parachute opening has very high requirements on the airtightness and temperature resistance of the rocket body, which are not easy to achieve in the field of model rockets. [0004] Although the purely mechanical parachute opening has a simple st...

AI Technical Summary

Problems solved by technology

[0003] The delayed explosion of the gunpowder and the opening of the parachute can easily cause the umbrella cloth to burn due to the sudden rise in temperature when the parachute is opened, causing the rocket to crash

In addition, explosive parachute opening has very high requirements on the airtightness and temperature resistance of the rocket body, which are not easy to achieve in the field of model rockets

[0004] Although the purely mechanical parachute opening has a simple structure, it cannot control the height of the parachute opening at will

[0005] The parachute opening mechanism of the existing carrier model rocket basically only considers the separation of the rocket body load and the parachute drop, and does not consider the separation of the load and the parachute when returning to the ground
