Detailed Description

The invention is further described below with reference to the figures and examples.

As shown in fig. 1 to 4, a hard drag parachute pack comprises a hard barrel 2, the top of the barrel 2 is slidably hung on a sky rail 3 in a parachute cabin, a through hole for penetrating through a drag parachute connecting hanging ring 13 is formed in the front end face of the barrel 2 (the drag parachute pack is conveniently separated during parachute throwing), the rear end face of the barrel 2 is provided with an opening, the opening is sealed by a pack buckle 10, a pack pulling rope 7 and a plurality of soft pack blades 12, the roots of the pack blades 12 are fixed on the edge of the opening, a ring 9 is arranged at the movable end, one end of the pack pulling rope 7 is provided with a contact pin, and the other end of the pack pulling rope is provided with an elastic buckle; during packaging, the packaging buckles 10 penetrate through all the circular rings 9, two ends of each packaging buckle 10 are simultaneously inserted by the inserting pins, the elastic clasps are hung on the umbrella cabin door, and the inserting pins can be driven to be pulled out of the packaging buckles 10 after the umbrella cabin door is opened. The hard cylinder body 2 is not easy to deform, so that the appearance forming degree of the drag parachute is not influenced, and the drag parachute is suitable for various drag parachutes; the hard cylinder bodies 2 are adopted, the cylinder bodies 2 are not interfered with each other, and can be closely arranged, so that the space utilization rate of the airplane is improved; the shape design of the cylinder body 2 can be flexibly carried out according to the size and the position of the umbrella cabin space, so that the structural design of the airplane is simplified; this umbrella package can be dismantled fast, even package stay cord 7 goes wrong when throwing and putting, also can take off the elasticity and detain, manual operation, use easy maintenance.
