Problems solved by technology

[0003] The deployment of the traditional drogue parachute is to blow up the canopy cover by explosive bolts, so that the drogue parachute is thrown out from the canopy and then unfolded. The explosive bolts and other pyrotechnics used in this method are not suitable for storage, the production cost is high, and there is a certain risk during use. Dangerous, requires frequent maintenance

Embodiment

[0039] Such as figure 1 As shown, the drogue parachute deployment device according to the embodiment of the present invention includes a projectile body 1 , lifting lugs 2 , aviation disconnection 3 , drogue parachute compartment 4 and a drogue parachute deployment mechanism 5 . The drogue parachute deploying device for bombing can open the drogue parachute hatch 19 at a specific height by making the parachute opening mechanism act. The projectile is connected to the pylon through the lifting lug 2 and the airdrop release plug 3. When it is detected that the projectile is detached from the pylon, the drogue parachute will be opened after 3 seconds to reduce the impact of the drogue parachute on the delivery aircraft.

[0040] The working principle of the present invention: the projectile is connected to the hanger through the lifting lug and the airdrop, and when it is detected that the projectile is disconnected from the hanger, the deceleration parachute will be opened after...

Abstract

The invention discloses a mechanical brake parachute unfolding device and unfolding method for a missile, and relates to the field of brake parachutes. The brake parachute unfolding mechanism for themissile comprises a missile body, a lifting lug, an air-drop release plug, a brake parachute cabin and a brake parachute unfolding mechanism, wherein the missile body is connected with a hanging framethrough the lifting lug and the air-drop release plug which are installed on the missile body, one end of the brake parachute cabin is connected with the missile body, the other end of the brake parachute cabin is provided with the brake parachute unfolding mechanism, and the brake parachute unfolding device for the missile can be used for opening a parachute at a specific height in a mechanicalmode so as to open the brake parachute. According to the technical scheme, the brake parachute can be stably and reliably opened, the safety in the using process is guaranteed, and the device can be applied to the civil field.

Description

technical field [0001] The invention relates to the field of drogue parachute, in particular to a mechanical type drogue parachute deployment device and a deployment method. Background technique [0002] With the development of drone technology, airdropping items from drones has become more and more normal. Airdropped items need to be decelerated by a deceleration parachute and then land at a stable speed to avoid damage to the airdropped items. Traditional deceleration parachute needs to be used When the pyrotechnic product opens the umbrella, the pyrotechnic product has unsafe factors and needs to be stored separately, which is very inconvenient to use. Now it is proposed that the parachute can be deployed stably and reliably without the use of pyrotechnics, and it has the function of multiple recycling. [0003] The deployment of the traditional drogue parachute is to blow up the canopy cover by explosive bolts, so that the drogue parachute is thrown out from the canopy ...
