Abstract
The utility model discloses a general aircraft lifesaving parachute based on micro-ventilation material, which comprises a canopy, a parachute cord and a parachute bag; the main material of the canopy is made of a micro-breathable material, the width of the canopy is of a multi-taper structure, the taper of the canopy is reduced in sequence, and two wire mesh wedge-shaped blocks are arranged on the lower portion of the rear portion of the canopy. The parachute has the advantages of small volume, light weight, fast parachute opening, reduction of parachute opening dynamic load and suitability for matching with general airplanes.
Description
Technical Field
The utility model belongs to aviation lifesaving field, concretely relates to general aircraft lifesaving umbrella based on ventilative material a little.
Background
The general aircrafts are the aircrafts with the most varieties, the most quantity and the most extensive purposes in the world at present, the general aircrafts in China mostly do not have special matched general aircraft passenger lifesaving parachutes, a passive lifesaving mode of forced landing assisted by energy-absorbing seats is generally adopted in emergency, and the forced landing is influenced by the terrain environment, the pilot driving skill and the psychological quality, so that the lives of passengers are greatly threatened. The military life-saving parachute has the characteristics of high parachute opening speed, high parachute opening height, large area, heavy weight and the like, and is not suitable for the matching requirements of the general plane.
In order to meet the higher requirements of the general aircraft on the volume, the weight and the parachute opening speed of the parachute, the reduction of the air permeability of the canopy material is an option. However, after the small air-permeable and slightly air-permeable textile material is used, the parachute opening dynamic load of the parachute is rapidly increased, the stability performance is deteriorated, and the damage probability of parachute jumping of passengers is increased, which is also the reason that the conventional life saving parachute adopts air-permeable fabric (or dares not to use slightly air-permeable material).
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a general aircraft lifesaving umbrella based on ventilative material a little, this lifesaving umbrella is small, light in weight, parachute opening fast, reduced parachute opening dynamic load, is applicable to supporting general aircraft.
The utility model adopts the technical proposal that:
a general aircraft lifesaving parachute based on a micro-breathable material comprises a canopy, a parachute cord and a parachute pack; the main material of the canopy is made of a micro-breathable material, the width of the canopy is of a multi-taper structure, the taper of the canopy is reduced in sequence, and two wire mesh wedge-shaped blocks are arranged on the lower portion of the rear portion of the canopy.
Furthermore, the umbrella has 20 umbrella cloth widths, and the length of a single umbrella cloth width is 3.6 m.
Further, the air permeability of the fabric of the micro-permeable material adopted by the main material of the canopy under the condition of 200mm water column pressure difference is 20L/m2·s。
The utility model has the advantages that:
the micro-permeable material enables the canopy to be inflated rapidly, not only enabling rapid opening of the canopy (in this embodiment, the average opening time is 1.74s), but also facilitating a reduction in canopy area (in this embodiment, canopy area is only 34.1 m)2) The weight of the umbrella is reduced; the multi-taper arrangement of the umbrella cover enables the umbrella cover to form reasonable closing, reduces the dynamic load of opening the umbrella and ensures the stability of the umbrella, thereby balancing the contradiction between the micro air permeability and the large dynamic load and poor stability of the opening the umbrella; the wire mesh wedge block provides horizontal speed and rotation capacity; the parachute has small volume, light weight, quick parachute opening, reduced parachute opening dynamic load, and applicability toThe airplane is matched with a general airplane.

In the figure: 1-canopy; 2-umbrella rope; 3-braces; 4-umbrella bag; 5-wire mesh wedge-shaped block.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and examples.
As shown in fig. 1 to 3, a general aircraft parachute based on a slightly breathable material comprises a canopy 1, a parachute cord 2 and a parachute pack 4; the main material of the canopy 1 is made of a micro-breathable material, the width of the canopy is of a multi-taper structure, the taper of the canopy is reduced in sequence, and two wire mesh wedge-shaped blocks 5 are arranged on the lower portion of the rear portion of the canopy 1. The micro-permeable material enables the canopy 1 to be inflated rapidly, not only enabling rapid opening of the canopy (in this embodiment, the average opening time is 1.74s), but also facilitating a reduction in the area of the canopy 1 (in this embodiment, the canopy area is only 34.1 m)2) The weight of the umbrella is reduced; the multi-taper arrangement of the umbrella cover breadth ensures that the umbrella cover 1 forms a reasonable closing, reduces the dynamic load of opening the umbrella and ensures the stability of the umbrella, thereby balancing the contradiction between the micro air permeability and the large dynamic load and poor stability of the opening the umbrella; the wire mesh wedge-shaped block 5 provides horizontal speed and rotation capacity; the parachute has the advantages of small volume, light weight, fast parachute opening, reduction of parachute opening dynamic load and suitability for matching with general airplanes.
As shown in fig. 1 and 2, in the present embodiment, the canopy 1 has 20 gores, the total length of a single gore is 3.6m, the width of the bottom end is 0.76m, the length of the first stage is 1.2m, the width of the thin end is 0.05m, the width of the thick end is 0.4m, and the total length of the first stage and the second stage is 2.8 m.
In this embodiment, the air permeability of the micro-permeable material used as the main material of the canopy 1 is 20L/m under the condition of water column pressure difference of 200mm2·s。
As shown in figure 3, when the general-purpose aircraft fails to control in the air and cannot force to land, the passengers on the aircraft can realize safe escape through the life-saving parachute: the airplane passenger jumps away from the airplane by carrying the lifesaving parachute, after the airplane passenger leaves the airplane, the parachute kit 4 is opened by a parachuting personnel through a parachute opening pull ring, after the parachute kit 4 is opened, the parachute kit 1 is guided to be rapidly inflated and fully expanded, the parachute kit 1 and the parachute cord 2 of the main parachute are pulled out through the connecting band and gradually straightened, the main parachute is inflated and fully expanded, the parachuting personnel stably descend by taking the lifesaving parachute, and in the stable descending process, the lifesaving parachute can be controlled by the parachute personnel through the control band of the shoulder straps 3 to avoid obstacles and find the ground or the water surface suitable for landing.
It will be understood that modifications and variations can be made by persons skilled in the art in light of the above teachings and all such modifications and variations are considered to be within the scope of the invention as defined by the following claims.
