Abstract
The invention discloses a safety speed-reducing device for a rocket, which comprises a speed-reducing section shell (5), a parachute (4), a powder box (1), a piston (2) and tail wings (3), wherein the speed-reducing section shell (5) is cylindrical in shape; four tail wings (3) are uniformly distributed outside the speed-reducing section shell (5); and the powder box (1), the piston (2) and the parachute (4) are arranged in the speed-reducing section shell (5) in turn. When the rocket is needed to be slowed down, powder in the powder box (1) is ignited; the high-pressure fuel gas is generated when the powder is burned; the piston (2) is pushed by the fuel gas and the parachute (4) is pushed out of the speed-reducing section shell (5) by the piston (2); the piston (2) is used for braking at a raised platform at the tail part of the speed-reducing section shell (5) and the parachute (4) is opened, so that a safety speed-reducing function is achieved; the fuel gas is separated from the parachute (4) by the piston (2), so that the parachute (4) is prevented from being damaged by the fuel gas; and the safety speed-reducing device for the rocket is simple in structure and high in reliability.
Description
Technical field
The present invention relates to a kind of safety speed reducer, particularly a kind of safety speed reducer that is used for rocket.
Background technology
Present airborne aircraft deceleration device comprises: braking section housing, mechanical gear, transmission device, drag parachute or flap; Through mechanical gear and transmission device active force is sent on drag parachute or the flap; Open drag parachute or flap, increase the effect that front face area plays deceleration.This apparatus structure is complicated, and gear is prone to break down.
Summary of the invention
The object of the present invention is to provide a kind of safety speed reducer that is used for rocket, the problem that the existing deceleration device complex structure of solution, gear are prone to break down.
A kind of safety speed reducer that is used for rocket comprises: braking section housing, parachute also comprise: medicine box, piston, empennage.The braking section housing is cylindric, and the afterbody of braking section housing has a circle boss, and the internal diameter of boss is less than the internal diameter of braking section housing; Four empennages are evenly distributed on the braking section hull outside, and fix with braking section housing screw, and medicine box places in the braking section housing; One end of medicine box is concordant with the top of braking section housing, and piston places in the braking section housing, and closely contacts with the other end of medicine box; Parachute places the braking section housing, and the umbrella line is connected between parachute and the piston.
When rocket need slow down, the fuse of rocket provided ignition signal and lights the powder charge in the medicine box, and the powder charge burning produces high-pressure gas, and combustion gas promotes piston; Piston promotes parachute, and parachute is released the braking section housing, and piston is braked at braking section housing afterbody boss place; At this moment, parachute opens in air, plays the effect that safety is slowed down; In this process, piston is isolated with combustion gas and parachute, avoids parachute to be destroyed by combustion gas.
The present invention is simple in structure, and reliability is high, has solved existing aircraft deceleration device complex structure, and gear is prone to cause the problem of fault.

The specific embodiment
A kind of safety speed reducer that is used for rocket comprises: braking section housing 5, parachute 4 also comprise: medicine box 1, piston 2, empennage 3.Braking section housing 5 is cylindric, and the afterbody of braking section housing 5 has a circle boss, and the internal diameter of boss is less than the internal diameter of braking section housing 5; Four empennages 3 are evenly distributed on braking section housing 5 outsides, and fix with braking section housing 5 screws, and medicine box 1 places in the braking section housing 5; One end of medicine box 1 is concordant with the top of braking section housing 5, and piston 2 places in the braking section housing 5, and closely contacts with the other end of medicine box 1; Parachute 4 places braking section housing 5, and the umbrella line is connected between parachute 4 and the piston 2.
When rocket need slow down, the fuse of rocket provided ignition signal and lights the powder charge in the medicine box 1, and the powder charge burning produces high-pressure gas, and combustion gas promotes piston 2; Piston 2 promotes parachute 4, and parachute 4 is released braking section housing 5, and piston 2 is braked at braking section housing 5 afterbody boss places; At this moment, parachute 4 opens in air, plays the effect that safety is slowed down; In this process, piston 2 is isolated with combustion gas and parachute 4, avoids parachute 4 to be destroyed by combustion gas.
