Abstract

The utility model relates to an emergency landing airdrop apparatus used by the personnel on an airdrop plane under the condition of the fact that a plane hedgehops. The utility model solves the problem that the personnel are easy to damage when an airdrop cabin heavily impinges. The apparatus is mainly characterized in that the outer surface of a spherical personnel cabin is covered by an aerating spherical touch type structure. The sporting windward resistance and the rolling resistance of the apparatus play a role of uniform speed reduction in the horizontal direction. In the vertical direction, the apparatus also has a good deceleration function and a buffer action. A top universal shaft frame is arranged in the cabin, which can ensure that the personnel cabin is stable when the apparatus rolls.

Description

Emergency landing apparatus

The utility model is to drop the employed dropping gear of persons on board about air force's penetrator under extreme low-altitude situation.

All adopt parachute when supply dropper aircraft carries out airborne assault in the operation DZ sky at present, shortcoming is for guaranteeing parachute-opening, 180～300 meters of supply dropper aircrafts in the sky, combat zone, be subject to ground small arms fire shooting with 130 joints than low velocity flight; in 20 to 30 seconds decline at a slow speed, easily hit after the paratrooper disembarks; people are studying near-earth air-drop scheme always,, increase sudden to break away from the tracking of radar and ground firepower effectively when maneuvering target.Have two kinds in the prior art, a kind of is the near-earth traction system, utilizes the ground cable wire to slow down, and a kind of is the low-altitude parachute traction system.Consult 52 pages of Air International 1991 10 phases, both actual features are the same, all be highly to drop personnel compartment at near-earth (overhead 5 meters) by aircraft, slow down by brake cable or parachute, though the parachute traction system is better, but common shortcoming is cable wire or parachute deceleration only to play a major role before personnel compartment is hit ground, and this time only has 0.2～2.0 second on this height, remaining horizontal velocity and nearly whole vertical speed are just main to rely on personnel compartment to realize with ground-surface 0～0.2 second bump, be easy to cause the personnel's of dropping from the air injures and deaths and lose fighting capacity, this scheme is very high to drop altitude and landing site requirements in addition, and success ratio will be very low under the operation circumstances.

The purpose of this utility model is to landing impact excessive problem in order to solve in the air penetration cable wire or the existing personnel compartment of low-altitude parachute traction system, guarantees that personnel are injury-free when near-earth drops, and improves near-earth air-drop personnel's implementation condition.

The utility model is achieved in that air-drop personnel and seat is fixed in the gyro versatile spindle system by spherical hard shell containing, constitutes the air-drop personnel compartment; The whisker type structure that covers with gas generator bottle, loading line and rectangular distribution on the hard shell surface constitutes the deceleration buffer system.

It is inflatable that the whisker type structure is made by airtight fabric, props up fork by mobile jib and top and forms, collapsible before the inflation;

Whisker type structure inflation back mobile jib can be along the expansion of hard shell Surface Vertical direction, and a fork interconnects composition net dress spherical surface body perpendicular to the fork that mobile jib is adjacent the antenna structure;

Hard shell be branch half or have the gangway, personnel enter can be with its locking in the duricrust;

Hard shell and personnel compartment seat are separately fixed on two separate axles of versatile spindle framework;

The center of gravity of air-drop personnel and seat is away from the intersection point of versatile spindle system, when hard shell during along arbitrary directional rolling personnel can remain a settling position;

Hard shell and antenna structure can be made with transparent material.

During near-earth air-drop beginning, airborne personnel enter the duricrust cabin and with its locking, when the duricrust cabin rolled out body, gas generator was worked automatically, launch the whisker type structure rapidly, begin after contacting to earth to roll, and personnel can jump out out of my cabin rapidly when stopping.

Adopt the utility model, the soft landing that the personnel that can realize directly do not contact to earth, advantage is outstanding when near-earth drops.The momentum of the vertical direction the during air-drop of its near-earth can be by the air resistance of antenna body motion and the elastic extenuation after contacting to earth, eliminated the vertical impingement phenomenon of air-drop personnel compartment in brake cable or the low-altitude parachute traction system, so the flying height to air-drop need be strict with, meet needs under battle conditions; The main deceleration direction of near-earth air-drop is a horizontal direction, the utility model has aerodynamic resistance properties similar to parachute and antenna that self adaptation resistance regulatory function is arranged on each sense of motion, the more important thing is that spherical antenna structure has good rolling resistance property, but the elimination of level bump prolongs moderating process; Do not limit with the utility model air-drop personnel place of landing, desert, Gobi desert, jungle, hills, marsh, the water surface all can, very strong comformability is arranged; Adopt the whisker type structure, available a small amount of gas is full of in a short period of time than large space, increases motion and rolling resistance, improves buffering effect, and viability is strong.

Specific embodiments signal of the present utility model as shown in the figure.

Fig. 1 is the longitudinal sectional drawing of a kind of concrete structure of the utility model;

Fig. 2 is transverse cross-sectional view of the present utility model (unaerated of antenna structure is attached to the hard shell surface).

Fig. 3 is that the situation arranged evenly that fork (9) constitutes a kind of embodiment of netted sphere is propped up on the surface of inflation antenna structure of the present utility model.

Launch with reference to well-distributed type inflatable antenna structure shown in Figure 1 (1) Surface Vertical direction along hard shell (3) after inflation; But hard shell has the gangway (2) of locking, there are gas generator bottle (8) and a corresponding loading line (not shown) and a versatile spindle framework (5) (6) in its inside, air-drop personnel (4), lie on the seat (7) with safety strap, and seat is fixed on wherein (6) of versatile spindle system.Prevent that along any personnel can keep settling position when rolling when this dropping gear lands,, this device can steadily be slowed down rapidly because the damping of facining the wind of gas filed antenna structure reaches in the damping in roll partly of contacting to earth.
