Abstract

The invention discloses a flexible folding type parapack, and belongs to the field of packaging. The purpose of the flexible folding type parapack is to solve the problems of accuracy and convenience degree of usage when an airplane paradrops objects. A flexible folding type of the flexible folding type parapack can be used for solving the problems of difficulties in usage and storage. A moving type air filling technology solves the problems of usage of parachutes in the air, and solves the problem that accuracy of parachute drop is poor, and cost can be reduced.

Description

Soft folded formula parapack

Technical field:

The present invention relates to a kind of packing of free-falling body.The packing of the foam material of the automatic inflating that can use when being particularly related to a kind of airplane air dropping article.

Background technology:

The foam packing is mainly XPE, PET, PU, four kinds of EPDM etc.Good buffering is arranged, and fire-retardant, anti-puncture performance can provide defencive function for falling objects.And the automatic inflating functional structure arranged.

Parapack reload request aircraft 80 metre per second (m/s) flying speeds are highly more than 100 meters, object to be thrown in.Waterproof at first after object lands, the pollution of mud etc.When there are the objects such as branch on ground, can not wear out.Most critical is to require in war, and airdrop hardware when the disasteies such as earthquake occur may have military notebook, and mineral water etc. are badly in need of the disaster relief supplies input, and just also requirement is shockproof for this.Easily highly do not open 100 meters left and right when parachute is thrown in addition, or former thereby waft from throwing in the place due to air-flow.The parachute cost is higher again.Now an above difficult problem is badly in need of solving in the air-drop field.To guarantee when dropping for about 100 meters, even weather is more abominable, also can accurately arrives and throw in the place.And object easily opens and uses after dropping to ground.

Description of drawings:

Fig. 1, the layer structure of bag.

Fig. 2, the section drawing of qi of chong channel ascending adversely equipment.

Summary of the invention;

This packing is exactly in order to overcome aircraft 100 meters low-latitude flyings, and parachute is not opened and price is high and a product of design, and this product operation is simple and easy, can open to pack without any need for instrument after landing and get thing.

The scheme of technical solution difficult point has the XPE that has at first selected antidetonation anti-puncture, the materials such as PET, and about 70 kilograms of every cubic meters of density, pulling strengrth is greater than 0.8 MPa, and disruption characteristic is greater than 836.21 newton.Can satisfy air-drop ground shock power.And related to unique campaign-styled self-filler, thus make airdrop hardware utilize the kinetic energy that potential energy changes in the free-falling body process and cause wind speed to raise, thus the automatic inflating function completed.Gas rests in internal airbag, and qi of chong channel ascending adversely valve autoshutdown when the unexpected kiss the earth of object makes the object that is pressed on air bag can not be badly shaken like this.Be provided with in addition slide fastener dress thing mouth, pull head had easily not open do not put.Object lands just can be opened without instrument afterwards with hand.
