Abstract

It the utility model is related to a kind of vertical recovery system of rocket, recovery tunnel including being arranged at underground, and the two-stage buffer subsystem in adit opening and tunnel enters row buffering, rocket caused by water filling prevents boost motor backflash in tunnel damages, by the above-mentioned means, the utility model can be as the vertical recovery tunnel of rocket, and without being changed greatly to rocket, rocket posture and position are adjusted by the boost motor for reclaiming level, it is fallen into tunnel and recycles, reduce rocket launching cost.

Description

A kind of vertical recovery system of rocket

Technical field

A kind of vertical recovery system of rocket is the utility model is related to, belongs to aerospace field.

Background technology

Rocket is carried in the early stage of development, in order to reach the purpose smoothly launched, each space power all disregards cost.With boat The development of its technology, each space power gradually start to consider launch cost problem, and low cost transmitting turns into space transportation system Development trend.

As the Overseas New carrier rocket using SpaceX Fa Erken Launch Vehicle Series as representative enters international commercial hair Market is penetrated, the price advantage that China's Long March series rockets possess in the past no longer exists.In addition, American Association transmitting alliance meter Draw and be greatly reduced current transmitting price before the year two thousand twenty, Europe and Japan are also all manufactured into setting about a new round and reduce rocket The work of sheet and launch cost.Therefore, there is an urgent need to carry out carrier rocket low-cost design technical research in China.

Vehicle, which is reused, can be achieved " being used for multiple times, expense is shared equally ", be reduce space launch cost main path it One, it is to realize the basis that carrier rocket is reused to carry out sub- level recovery technology.China does not currently possess carrier rocket level still Recovery ability.It is contemplated that design a kind of carrier rocket level recovery method.

Utility model content

In order to solve the above technical problems, the technical scheme that the utility model uses is：A kind of rocket, which vertically reclaims, is System, including recovery tunnel, it is characterised in that the recovery tunnel is arranged at underground, and adit opening is parallel to the ground, in inverted cone Body structure；Adit opening covers first-level buffer net, and level 2 buffering net is set in tunnel, sets fixation to grab rake between two-stage buffer subsystem；

Tunnel side wall accesses filling pipe outside tunnel, and level 2 buffering side off the net discharges water, and prevents high temperature from exploding；Tunnel peripheral hardware Put signal lamp；

The recovery system also includes the recovery boost motor being arranged on rocket, is connected to by screw bar member outside rocket Wall.

Preferably, the recovery tunnel depth 100-150m, it is ensured that whole recovery rocket can be stood in tunnel.

Preferably, the adit opening diameter 30-40m, tunnel base diameter 10-15m is reclaimed.

Preferably, spacing 30-40m between the two-stage buffer subsystem, filling pipe entrance are located at level 2 buffering side off the net, water Face height distance level 2 buffering net at least 20m.

Preferably, the first-level buffer net uses wire netting with level 2 buffering net.

The situation of prior art is different from, the beneficial effects of the utility model are：

1st, to realize that reuse is taken a firm foundation, it can promote sub- level recovery to exist as a general technology Possible overall application in various carrier rocket, it is the cost degradation of China's carrier rocket and improves commercial launch market competition Power provides important way.

2nd, reclaimed using tunnel type, without larger change is carried out to rocket, it is necessary to its outside a small amount of boost motor in field with Ensure the flight course control in removal process.

3rd, tunnel is arranged at underground, and use water is filled, and prevents the excessive accident caused by of being generated heat in dropping process, i.e., It is recovery failure, is exploded in tunnel, tunnel can also effectively reduce impulse radius.

Brief description of the drawings

Fig. 1 is the structure chart of the vertical recovery system of the utility model rocket.

Fig. 2 is the utility model rocket structure figure.

Fig. 3 is that the utility model rocket reclaims complete placement figure.

Embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out Clearly and completely describing, it is clear that described embodiment is only part of the embodiment of the present utility model, rather than whole Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made The every other embodiment obtained, belong to the scope of the utility model protection.

The vertical recovery system of a kind of rocket provided referring to Fig. 1, including recovery tunnel, it is characterised in that the recovery hole Road 1 is arranged at underground, and adit opening is parallel to the ground, in inverted cone body structure；Adit opening covering first-level buffer net 2, in tunnel Level 2 buffering net 3 is set, sets fixation to grab rake 7 between two-stage buffer subsystem；

Tunnel side wall accesses filling pipe 6 outside tunnel, and level 2 buffering side off the net discharges water 4, prevents high temperature from exploding；Outside tunnel Setting signal indicator lamp 5；

The recovery system also includes the recovery boost motor 9 being arranged on rocket, is connected to by screw bar member 8 outside rocket Wall.

Specifically, the recovery tunnel depth 100-150m, it is ensured that whole recovery rocket can be stood in tunnel.

The adit opening diameter 30-40m, reclaim tunnel base diameter 10-15m.

Spacing 30-40m between the two-stage buffer subsystem, filling pipe entrance are located at level 2 buffering side off the net, water surface elevation Apart from level 2 buffering net at least 20m.

The first-level buffer net uses wire netting with level 2 buffering net.

Rocket is with after satellite dropping, adjusting rocket posture by rocket side wall boost motor in removal process, can hang down excessively Under straight and position to recovery tunnel, because rocket bottom boost motor flame temperature is up to 3000-4000 DEG C, fall in adit opening Wire netting can fuse wire netting, reach buffering effect, while two-stage buffering ensure that rocket will not be because during falling Damaged for too fast shaken caused by of falling speed, the water layer in tunnel can cause rocket will not be because of boosting after falling hole The backflash of device and burn recovery rocket, play cooling explosion prevention function, after rocket stabilization dropping place, the fixation on tunnel inwall Rocket can be fixed in recovery tunnel by grabbing rake.

Embodiment of the present utility model is the foregoing is only, not thereby limits the scope of the claims of the present utility model, it is every The equivalent structure or equivalent flow conversion made using the utility model specification and accompanying drawing content, or be directly or indirectly used in Other related technical areas, similarly it is included in scope of patent protection of the present utility model.
