Abstract
The present invention relates to method that is a kind of while reducing Parachute Opening impact and reduce parachute level, connection sets several restrainings at the different height of bell, restraining prevents parachute from being fully deployed in one week around parachute, the separator for restraining to be cut off is equipped with restraining, parachute is after pack pull-out, canopy bottom, which inflates to be filled at once, completes the expansion of first order canopy, when a certain speed is surely down to, the separated device cut-out of the restraining of bottom, complete the expansion of second level canopy, restraining is cut off successively from the bottom up afterwards, canopy is set to deploy step by step from the bottom up until parachute is filled completely.The present invention makes parachute change into the expansion in order of increase step by step by all expansion when opening, simple to operate, reliability is high, meets system off-load, the requirement slowed down.
Description
Technical field
The invention belongs to the field of dropping, and in particular to a kind of to reduce Parachute Opening impact simultaneously and reduce parachute level
Method.
Background technology
Parachute be it is a kind of by made of flexible fabric, small volume after soft texture, packaging, be full of after than folding when resistance
Face big tens accompanies even hundreds of aerial delivery provisions accompanied, the object dropped to reduce decrease speed in the presence of parachute, real
Safe falling is showed.
When parachute aerial delivery system is dropped, initial velocity is typically higher, if directly deploying large-scale parachute, due to
Large-scale deployment area is big, and after moment inflation, parachute aerial delivery system can rapidly slow down, equipment, goods and materials and parachute it
Between can produce larger relative motion, bring huge impact, cause to overload.
If the initial velocity of air-drop is higher, in order to reduce Parachute Opening impact, meet off-load, the requirement slowed down, mesh
Preceding to be slowed down step by step, departed from using multistage parachute, final final stage parachute lands.This multi-layer parachute, program are lengthy and tedious multiple
Miscellaneous, reliability is low, and cost is high.
The content of the invention
It is an object of the invention to provide method that is a kind of while reducing Parachute Opening impact and reduce parachute level, make
Parachute changes into the expansion in order of increase step by step when opening by all expansion, reduces the parachute-opening that instantaneous large area expansion is brought
Impact acceleration, it can play and slow down and the requirement steadily landed, it is simple to operate, reliability is high, meet system off-load, slow down
It is required that.
The technical solution adopted in the present invention is：
Method that is a kind of while reducing Parachute Opening impact and reduce parachute level is high in the difference of bell
Connection sets several restrainings at degree, and restraining prevents parachute from being fully deployed in one week around parachute, on restraining
Provided with the separator for restraining to be cut off, for parachute after pack pull-out, canopy bottom inflates the completion that is filled at once
First order canopy deploys, and when a certain speed is surely down to, the separated device cut-out of restraining of bottom, completes second level canopy
Expansion, restraining is cut off successively from the bottom up afterwards, canopy is deployed step by step from the bottom up until parachute is filled completely.
Further, restraining passes through the retainer ring on canopy.
Further, restraining adjustable in length.
Further, it is bound and each selects mutually to fit according to parachute-opening intensity and performance requirement with the canopy not at the same level separated
The material answered.
The beneficial effects of the invention are as follows：
1. the present invention makes parachute change into the expansion in order of increase step by step by all expansion when opening, reduce instantaneous big
The opening shock load that area expansion is brought, because effective developed area increases step by step, therefore deceleration can be played and steadily fallen
The requirement on ground, it is simple to operate, reliability is high compared with multistage parachute, meet system off-load, the requirement slowed down.
2. restraining is limited by retainer ring, will not come off halfway.
3. only needing regulation constraint strip length to adjust developed area, implement simply, versatile, cost is low.
Brief description of the drawings
Fig. 1 is schematic diagram when canopy is the partially unfolded in the embodiment of the present invention.
Fig. 2 is schematic diagram when canopy is fully deployed in the embodiment of the present invention.
In figure：1- first order canopies；2- second level canopy；3- third level canopies；4- fourth stage canopies；5- restrainings；6-
Separator；7- parachutes.
Specific embodiment
Invention is further described with reference to the accompanying drawings and examples.
Method that is a kind of while reducing Parachute Opening impact and reduce parachute level, as shown in figure 1, in parachute 7
Connection sets several restrainings 5 at the different height of canopy, and restraining 5 prevents parachute 7 for 7 one weeks from complete around parachute
Deploy, the separator 6 for restraining 5 to be cut off is equipped with restraining 5, for parachute 7 after pack pull-out, canopy is most lower
Side inflates the completion first order canopy 1 that is filled and deployed at once, and when a certain speed is surely down to, the restraining 5 of bottom, which is separated, to be filled
6 cut-outs are put, second level canopy 2 is completed and deploys, restraining 5 is cut off successively from the bottom up afterwards, canopy is opened up step by step from the bottom up
Open until parachute 7 is filled (as shown in Figure 2) completely.
In the present embodiment, restraining 5 passes through the retainer ring on canopy.Restraining 5 is limited by retainer ring, will not take off halfway
Fall.
In the present embodiment, the adjustable in length of restraining 5.Only need to adjust the i.e. adjustable developed area of the length of restraining 5,
Implement simply, versatile, cost is low.
The canopy not at the same level for being bound the separation of band 5 each selects adaptable material according to parachute-opening intensity and performance requirement
(mainly Air permenbility and intensity index).
The present invention makes parachute 7 change into the expansion in order of increase step by step by all expansion when opening, and reduces instantaneous big
The opening shock load that area expansion is brought, because effective developed area increases step by step, therefore deceleration can be played and steadily fallen
The requirement on ground, it is simple to operate, reliability is high compared with multistage parachute, meet system off-load, the requirement slowed down.
It should be appreciated that for those of ordinary skills, can according to the above description be improved or converted,
And all these modifications and variations should all belong to the protection domain of appended claims of the present invention.
