The present invention provides a kind of secondary parachute-opening safety landing systems in side, including storepipe, hatchcover, parachute, drive end bearing bracket, rear end cap, closing in rope and electronics wire rope cutter；Storepipe side is open, and both ends are closed by drive end bearing bracket, rear end cap, and open side is detachably connectable by hatchcover；Parachute is fixedly connected with hatchcover, and is fixedly connected respectively with drive end bearing bracket, rear end cap by two umbrella bands, while parachute bottom is by rope tightening of closing up；Rope close up across electronics wire rope cutter, electronics wire rope cutter is fixed on parachute；When hatchcover is separated with storepipe, parachute pull-out, when rocket whereabouts reaches certain position, electronics wire rope cutter will close up to restrict and cut off, and parachute opens completely.The present invention can be effectively reduced rocket opening shock, improve rocket safety and reliability.
Description
Technical field
The present invention relates to operation rocketry fields, and in particular to a kind of secondary parachute-opening safety landing system in side.
Background technique
Weather modification is the mankind to produce and living needs are overcome or alleviated by by severe day by human intervention
Natural calamity caused by gas, and then under proper condition, the activity for promoting weather to develop to the direction for being conducive to human needs.Mesh
A kind of important operation means of preceding China's weather modification are exactly to pass through Weather modification operation rocket (hereinafter referred to as " people
Shadow rocket "), catalyst is sowed in target cloud layer to achieve the effect that increase rain, increase snow or hail suppression.Safety landing system is used for
The recycling of rocket remains after the completion of shadow rocket operation is landed rocket remains safely with lower speed using parachute, prevented
Only personnel and facility etc. are damaged.
The safety landing system of tradition shadow rocket is predominantly located in head at present, will even using the principle of rocket pressurized strut
Binding structure destroys, and discharges parachute, realizes parachute-opening.That there are opening shocks is big for this safety landing system, reliability is lower, safety
The problems such as property is not high, the hang time is long.Safety landing system is installed on middle part by another shadow rocket, passes through side parachute-opening
Mode, which discharges parachute, realizes parachute-opening, and rocket remains and ground is made to land at low-angle angle posture, can when alleviating landing
It is endangered caused by energy, but this safety landing system has that the hang time is long, structure is complicated, while also not solving thoroughly
The certainly big problem of rocket remains opening shock.
Summary of the invention
In view of this, can be effectively reduced rocket the present invention provides a kind of secondary parachute-opening safety landing system in side and open
Umbrella dynamic load improves rocket safety and reliability.
A specific embodiment of the invention is as follows:
A kind of secondary parachute-opening safety landing system in side, including storepipe, hatchcover, parachute, drive end bearing bracket, rear end cap,
Close up rope and electronics wire rope cutter；
The storepipe side is open, and both ends are closed by drive end bearing bracket, rear end cap, and open side connects by the way that hatchcover is separable
It connects；The parachute is fixedly connected with hatchcover, and is fixedly connected respectively with drive end bearing bracket, rear end cap by two umbrella bands, is dropped simultaneously
Umbrella umbrella bottom is fallen by rope tightening of closing up；Across electronics wire rope cutter, electronics wire rope cutter is fixed on parachute the closing in rope；
When hatchcover is separated with storepipe, parachute is pulled out, and when rocket whereabouts reaches certain position, electronics wire rope cutter will be received
Mouth rope cutting, parachute open completely.
Further, the detachably connectable mode of the hatchcover are as follows: hatchcover one end is loaded in storepipe by boss
Wall, the other end, which is fixed on, to open the cabin on priming system；The priming system that opens the cabin is fixed on drive end bearing bracket.
Further, it is determined when the position detects predetermined atmospheric value by the pressure sensor in electronics wire rope cutter.
The utility model has the advantages that
The present invention can be effectively reduced rocket opening shock by way of the secondary parachute-opening in side, improve rocket safety
And reliability, while can effectively shorten the rocket remains hang time.
Detailed description of the invention
Fig. 1 is overall structure diagram of the invention；
Fig. 2 is secondary opening process schematic diagram of the invention.
Wherein, 1- storepipe, 2- hatchcover, 3- open the cabin priming system, 4- zigzag shape clip, 5- draw umbrella ring, 6- parachute, 7-
Umbrella connector after rear end cap, 8-, 9- close up umbrella connector, 12- drive end bearing bracket before rope, 10- electronics wire rope cutter, 11-.
Specific embodiment
The present invention will now be described in detail with reference to the accompanying drawings and examples.
The present invention provides a kind of secondary parachute-opening safety landing systems in side, as shown in Figure 1, including storepipe 1, hatchcover
2, open the cabin priming system 3, zigzag shape clip 4, draw umbrella ring 5, parachute 6, rear end cap 7, rear umbrella connector 8, the rope 9 that closes up, electronics cuts
Rope device 10, preceding umbrella connector 11, drive end bearing bracket 12.
The opening of 1 side of storepipe, drive end bearing bracket 12 and rear end cap 7 are fixed on 1 both ends of storepipe by radial screw, open
Mouth side is detachably connectable by hatchcover 2, and 2 one end of hatchcover is loaded on 1 inner wall of storepipe by boss, and the other end is solid by screw
Due on the priming system 3 that opens the cabin, the priming system 3 that opens the cabin is fixed on drive end bearing bracket 12 by zigzag shape clip 4.
Parachute 6 is by drawing umbrella ring 5 to be fixedly connected with hatchcover 2.Parachute 6 has two umbrella bands, is connected respectively by preceding umbrella
Part 11 and rear umbrella connector 8 are fixed on drive end bearing bracket 12 and rear end cap 7, and preceding umbrella connector 11 and rear umbrella connector 8 are a few words
Shape, preceding umbrella connector 11 and rear umbrella connector 8 pass through umbrella band end and are fixed by screws on end cap, while 6 umbrella of parachute
Bottom is by 9 tightening of rope of closing up.The rope 9 that closes up passes through electronics wire rope cutter 10, and electronics wire rope cutter 10 is fixed on 6 bottom edge of parachute.
As shown in Fig. 2, sequence controller provides firing command on arrow after reaching the predetermined time, 3 work of priming system of opening the cabin
Make, hatchcover 2 is opened, while the circuit of electronics wire rope cutter 10 is started to work.Parachute 6 is in 2 pulling force of hatchcover and Aerodynamic force action
Under pulled out inside storepipe 1, umbrella band be straightened and start inflation slow down, due to close up rope 9 by 6 bottom edge of parachute tighten, drop
It falls umbrella 6 not open completely, on the one hand substantially reduces opening shock, rocket remains is on the one hand made to fall with fast speed.It arrives
When up to apart from ground 1km~2km, when the pressure sensor in electronics wire rope cutter 10 detects predetermined atmospheric value, electronics cuts rope
Device 10 is lighted a fire, and will close up 9 cutting of rope, and parachute 6 opens completely, and rocket remains are slowly fallen with smaller speed, until falling
The recycling of rocket remains is realized on ground.
In conclusion the above is merely preferred embodiments of the present invention, being not intended to limit the scope of the present invention.
All within the spirits and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in of the invention
Within protection scope.
