Description
Technical field
The present invention relates to rocketsonde technical fields, and in particular to rapid deployment object umbrella under a kind of high-altitude low density condition
System.
Background technique
Near space environmental parameter is directly measured using rocketsonde, is most effective Atmospheric sounding in upper air means, is
The accurate true environmental parameter for measuring local height also needs to provide for sonde to fill in addition to sonde carries out special designing
The local height layer residence time divided, while unnecessary interference can't be caused to sonde.
It is equipped using the meteorological sounding rocket detection system of parachuting sonde, is flown by sending out system completed 25 at present
Row interpretation of result, high-altitude low-density aerodynamic conditions are faint, and body-parachute system reduction of speed effect shows slightly insufficient after Separation, and flight is to wanting
When seeking height 60km~70km, sonde reduction of speed cannot be met the requirements very well, and there are apparent Aerodynamic Heatings to influence for detection data
Deng interference, detection accuracy is influenced.
Summary of the invention
In view of this, can be realized object the present invention provides rapid deployment body-parachute system under a kind of high-altitude low density condition
The rapid deployment of umbrella system simultaneously enhances system reliability, meets 60km~70km Atmospheric sounding in upper air demand.
Specific embodiments of the present invention are as follows:
Rapid deployment body-parachute system under a kind of high-altitude low density condition, including actively carried along pull-type parachute system, effectively
Lotus, buffer strip and snub rope；
Payload, actively along pull-type parachute system, is actively passed through along pull-type parachute system slow by snub rope's connection
It rushes band to connect with external rocket body, using payload as power source, parachute is actively straightened, make actively along pull-type parachute system
System orderly expansion.
Further, the active includes: main chute, pack, umbrella rope packet, umbrella rope fixing belt, rotation along pull-type parachute system
Adapter and lead top rope；
Main chute includes canopy and umbrella rope, and the canopy folding is placed in pack, and canopy top is by leading top rope and pack bottom
Portion's connection, using umbrella rope by pack package；
Umbrella rope packet is fixedly connected with pack, is limited by umbrella rope fixing belt in umbrella rope after the umbrella rope doubling outside pack
It wraps, umbrella rope end portion connects the snub rope by rotary joint；
After umbrella rope is straightened, pack is opened, canopy pull-out, breaks lead top rope under external force, and canopy and pack are completed to divide
From canopy expansion.
Further, the main chute uses disk-gap-band parachute.
Further, the top rope that leads is using cotton cord.
The utility model has the advantages that
1, the present invention replaces extractor parachute using payload as power source, and parachute is actively straightened, keeps body-parachute system fast
A possibility that orderly expansion of speed, the umbrella rope avoided generates winding during being straightened, improve parachute-opening reliability；Drop is quickly straightened
Umbrella is fallen, the time has been saved for the expansion of parachute system, in same discharge point height, effective work of sonde can be improved
Make height.
2, the present invention is actively simple and reliable for structure along pull-type parachute system, and occupancy inner space is small, and versatility is stronger.
3, the present invention uses disk-gap-band parachute, and developed area is big, being capable of rapid deployment in the environment of high-altitude low density condition.

Specific embodiment
The present invention will now be described in detail with reference to the accompanying drawings and examples.
The present invention provides rapid deployment body-parachute systems under a kind of high-altitude low density condition, as shown in Figure 1, including actively suitable
Pull-type parachute system, payload, buffer strip 10 and snub rope 6.
Actively along pull-type parachute system include: main chute, pack 1, umbrella rope packet 2, umbrella rope fixing belt, rotary joint 5 and
Lead top rope 11；Main chute is disk-gap-band parachute, including canopy 3 and umbrella rope 4, and the top of canopy 3 is connect by leading top rope 11 with 1 bottom of pack,
Folding is placed in pack 1, using umbrella rope 4 by 1 package of pack；Be sewed with umbrella rope fixing belt in 1 lid of pack, umbrella rope packet 2 with
Pack 1 is sewed together, and the limit of umbrella rope fixing belt is passed through after 4 doubling of umbrella rope outside pack 1 on umbrella rope packet 2, can be with
Guarantee to open package again after 4 overall length of umbrella rope is straightened, it is ensured that umbrella rope 4, canopy 3 can push down drawing sequential deployment.4 end of umbrella rope passes through rotation
Adapter 5 connect snub rope 6, rotary joint 5 can n × 360 ° rotation, n represent circle number, for eliminate payload rotation imitate
Fruit.
As shown in Fig. 2, payload includes instrument stand 7, sonde 8 in the present embodiment, instrument stand 7 is connected by instrument stand
Rope 9 and sonde 8 connect.Instrument stand 7 connects the actively rotary joint 5 along pull-type parachute system by snub rope 6, actively suitable
The pack 1 of pull-type parachute system is connect by buffer strip 10 with the piston 14 being arranged in rocket cabin 12, is had on buffer strip 10
Five equally distributed buffering knots, reduce maximum impact suffered by buffer strip 10, guarantee the structural reliability of body-parachute system.Using having
Load is imitated as power source, parachute is actively straightened, makes actively orderly to be unfolded along pull-type parachute system.
Workflow is as follows: as shown in figure 3, after separation igniting, the separation of rocket head body is acted in 15 expansive force of priming system
Under, lining tile 13, body-parachute system release cockpit by piston 14, and piston 14 is prevented, and body-parachute system continues to move, and pack 1 is restricted
Also prevented in piston motion stroke, later sonde 8, instrument stand 7 inertia force effect subumbrella rope 4 by successively in an orderly manner from
It pulls out, be straightened in umbrella rope packet 2, after pack 1 is opened, canopy 3 is pulled out from pack 1, is straightened, and breaks the top of canopy 3 and 1 bottom of pack
Lead top rope 11, canopy 3 is separated with pack 1, rocket body, and body-parachute system starts free-falling, the opening rapidly of canopy 3, body-parachute system
It reduces speed now until reaching the speed of the needs of sonde 8, sonde 8 starts to work normally, and acquires local weather information.
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.
