Technical Field

The invention belongs to the field of air drop, and particularly relates to a method for improving parachute opening synchronism of a multi-parachute system.

Background

Along with large-scale cargo airplane equipment army, air-drop system weight is bigger and bigger, theoretically, use single parachute can satisfy the needs of air-drop system, but discover in the in-service use, when heavier to the system, if adopt single parachute to carry out the system air-drop, can bring a series of problems, for example, the packing of super large-scale parachute, folding, the parachute opening scheduling problem is all more complicated, in addition, in the production and processing, use in the aspect of maintaining, super large-scale parachute is because the area is big, the weight is heavy, all bring very big inconvenience, also promote by a wide margin in use cost. Therefore, under many circumstances, when the aerial delivery system is heavy, the multi-umbrella system is generally adopted for carrying out system aerial delivery, so that a series of problems of processing, use, maintenance and the like are avoided, but the asynchronism of opening the multi-umbrella system is a problem to be solved.

When a traditional multi-parachute system is airdropped, the only related parts among single parachutes are parachute tops, small parachutes are adopted to pull the tops of the parachutes to inflate, during packaging, the single parachutes are packaged by using independent parachute bags, the canopy is placed in the parachute bags after being folded, when the parachutes are unfolded, the canopy is pulled out of the parachute bags to be unfolded and inflated, parachute rope ends among the parachutes are simultaneously connected to an airdropped article fixed end of the airdropped system, a mode of closing the multi-parachutes is adopted, and the parachute opening program is controlled.

When the multi-umbrella system is opened, due to the asynchronism of inflation and unfolding among the multi-umbrella systems, the parachute which is firstly opened and inflated is easily overloaded when being opened, the canopy is damaged, and after all the umbrellas are unfolded and inflated to be full, the performance of the multi-umbrella system is reduced.

Disclosure of Invention

The invention aims to provide a method for improving the parachute opening synchronism of a multi-parachute system, the canopy can be pulled out section by section for inflation, each parachute is ensured to be inflated synchronously until the parachute is fully inflated, the parachute opening synchronism of the multi-parachute system is improved, and the method is simple to manufacture and transform and low in cost.

The technical scheme adopted by the invention is as follows:

a method for promoting the parachute opening synchronism of a multi-parachute system comprises the steps that outer rope buckles are evenly sewn on the periphery of the outer side of a canopy of a parachute along the line, inner rope buckles corresponding to the outer rope buckles in a one-to-one mode are sewn on the inner sides of canopy sleeves, the canopy is arranged in the corresponding canopy sleeves, the corresponding outer rope buckles and the inner rope buckles are connected through connecting ropes, the working length of the connecting ropes is sequentially increased from the bottom edge to the top of the canopy, all the canopy sleeves are arranged in a canopy bag, the canopy ropes of the parachute are arranged in rope sleeves on the outer side of the canopy bag, the top of the canopy is connected with the canopy through strong connecting ropes, and the top of the canopy is connected with the canopy through fixed-force ropes; when the multi-umbrella system works, all the umbrella ropes are pulled out from the rope binding sleeves synchronously, then all the umbrella sleeves are pulled out from the umbrella bag synchronously, and finally all the umbrella coats are pulled out from the corresponding umbrella sleeves synchronously.

Furthermore, the outer rope buckle and the inner rope buckle are respectively positioned on the reinforced belts of the umbrella coat and the umbrella cover.

Furthermore, two ends of the connecting rope are respectively bound with the outer rope buckle and the inner rope buckle through plain knots.

Further, the canopy length exactly covers the length of the canopy from the bottom edge to the top.

Furthermore, the umbrella cover is stacked in the umbrella bag in a Z shape.

Further, the connecting rope is a cotton rope.

The invention has the beneficial effects that:

the working length of the connecting rope is sequentially increased from the bottom edge to the top of the canopy, so that the upper end of the canopy is still arranged in the canopy sleeve when the bottom edge of the canopy starts to be inflated, the canopy can be pulled out section by section to be inflated, the inflation time is prolonged, and each parachute is inflated synchronously until the parachute is fully inflated, so that the parachute opening synchronism of a multi-parachute system is improved, and parachute opening impact overload received when a single parachute is inflated is reduced; the umbrella opening synchronization of the multi-umbrella system can be realized only by additionally arranging the connecting rope, the outer rope buckle and the inner rope buckle, and the umbrella opening synchronization system is simple to manufacture and transform and low in cost.
