Description

Quick parachute for air drop

Technical Field

The invention relates to the field of air material transportation, in particular to a quick parachute for air drop.

Background

The parachute is a deployable aerodynamic speed reducer which is inflated and deployed relative to the air movement by utilizing the principle of air resistance. Modern parachutes are aerial vehicles that safely descend persons or things from the air to the ground. Mainly made of flexible fabric. The air-drop flight training device is equipment for air-drop soldier combat and training, lifesaving and training of aerospace personnel, training, competition and performance of parachutists, air-drop supplies and aircraft recovery.

At present, after the parachute is opened, the falling speed is usually 8m/s, relatively speaking, the falling speed is slow, the falling time is too long due to too slow falling speed, the falling time is too long due to too long stay in the air, the landing time of the air drop is long, and the landing position deviation is large, so that the parachute capable of rapidly falling is urgently needed.

Disclosure of Invention

The technical problem to be solved by the invention is as follows: overcomes the defects of the prior art and provides a quick parachute for airdrop.

The technical scheme adopted by the invention for solving the technical problems is as follows: the utility model provides a quick parachute of air-drop usefulness, includes fixed canopy and the parachute line that sets up, the canopy constitutes for the umbrella stick that many crosses interweaved, and 1cm is no less than at the interval of umbrella stick, and the umbrella stick is a textile material who is the bar, and the cross interweaves and is similar to the mode that bamboo article was made to original bamboo chip, and adjacent umbrella stick position sets up one on the other.

Furthermore, the width of the umbrella strips is at least 40cm and less than 20 cm, the umbrella strips are difficult to interweave, and the delay time is too long.

Further, the number of the umbrella bars is 6 ~ 12, and the umbrella bars are a total number, generally in the horizontal and vertical directions, and the interleaving method is the prior art.

Furthermore, the number of the umbrella strips is even and the umbrella strips are arranged conventionally.

Further, the umbrella stick length is 250cm ~ 350 cm.

Further, the center of the canopy is provided with an umbrella top hole for improving stability.

Furthermore, be equipped with the connecting band between the adjacent umbrella stick, when not having the connecting band, the umbrella stick word is independent, has certain inclination after being full of the air, and the angle diverse, so increase the connecting band on each umbrella stick, be that each umbrella stick becomes a whole, reduces the rotation of parachute.

Furthermore, the umbrella strips are fixedly connected through sewing, and the crossed and interwoven positions of the umbrella strips are fixedly connected through sewing, so that the umbrella strips are ensured to be fixed with each other.

Further, the number of the umbrella strips is 12, the spacing between the umbrella strips is 5cm, and the area of the umbrella cover is 0.9m²The width of the umbrella stick is 40cm ~ 50 cm.

Further, the umbrella stick is a 43mm cotton silk ribbon.

The invention has the beneficial effects that: according to the invention, through the crossed parachutes, a certain gap exists between every two parachute strips, so that the landing speed can be effectively improved, the time in the air is saved, the landing deviation is reduced, and the time of airdrop in the visual field of enemy is also reduced.

Detailed Description

The invention is further explained with reference to the drawings and the embodiments.

Example 1

Referring to fig. 1, the rapid parachute for air drop comprises a canopy 1 and a parachute cord 2 which are fixedly arranged, the canopy 1 is composed of a plurality of crisscross umbrella strips 3, the number of the umbrella strips 3 is 12, the interval of the umbrella strips 3 is 5cm, the width of the umbrella strips 3 is 40 ~ 50cm, the length of the umbrella strips 3 is 300cm, the umbrella strips 3 are crisscross interwoven in the central area of the canopy 1, and the umbrella strips 3 are splash-proof high-strength nylon cloth.

The umbrella rope 2 is fixedly arranged in the umbrella strip 3 in a penetrating way, the umbrella strip 3 can be of a two-layer structure, when the umbrella strip 3 is fixed, the umbrella rope 2 is arranged in the umbrella strip 3, and can be spliced, glued and the like. The umbrella cord 2 is preferably arranged on the middle line of the umbrella strip 3. The umbrella strips 3 are fixedly connected through sewing, the crossed and interwoven positions of the umbrella strips 3 are fixedly connected through sewing, so that the umbrella strips 3 are ensured to be fixed with each other, and the positions of the adjacent umbrella strips 3 are arranged one above the other.

The above is the embodiment corresponding to the figure, wherein the total number of the umbrella strips 3 is 6, 8, 10 and 12, and most preferably, more or less than all of the umbrella strips have certain defects; the width of the umbrella strips 3 is at least 40cm, the umbrella strips are less than 40cm and are difficult to interweave, and too much delay time is caused; the spacing of the umbrella strips 3 is not less than 1cm, the spacing is too small, the resistance is too large, the purpose of quick falling is difficult to achieve, and the umbrella strips 3 can be made of other materials, such as fibers and the like.

Referring to fig. 2, in the parachute of the present invention, it is preferably connected to the airdrop box in such a manner that the airdrop box has four lateral sides connected to the parachute lines 2 of the present invention as shown in the drawing, and when each lateral side is connected to a plurality of parachute lines 2, the connection point is preferably on a horizontal straight line, and of course, the parachute lines 2 of each lateral side may be on one point, but there is no horizontal straight line as shown in the drawing, and the parachute is easily shaken when it is airdropped in the air.

The working principle and the using method of the invention are as follows: according to the invention, through the crisscross umbrella strips 3, and a certain gap exists between the umbrella strips 3, by taking the specific embodiment of the attached drawings as a reference, the canopy 1 has an interval of one fifth of the area, the air permeability is far greater than that of a traditional parachute, the falling ripening speed of the traditional parachute is generally 8m/s, the parachute of the invention can reach 16m/s under the same condition, the falling time is greatly reduced, the gas fluidity is good, the airdrop smoothness is high, the airdrop exposure time in the air is reduced under the condition of the landing impact which can be borne by the airdrop, and the landing accuracy is improved.

The using method of the parachute is consistent with that of the traditional parachute, the parachute is connected with the air-drop box and pushed out along with air-drop, and the parachute can be opened when a certain speed is reached, which is the prior art, so that redundant description is omitted.
