Abstract
The utility model discloses a novel annular stable speed-reducing umbrella adopts the canopy of sewing up the back for ellipsoid, and the shape ellipsoid of canopy leads a rope one end to connect the umbrella top, and the other end links to each other with umbrella rope convergent point, through leading a rope pull-down umbrella top. Adopt the utility model discloses a scheme has improved the aerial stability of stable drag parachute, can solve the parachute soldier and fall freely for a long time when jumping to open by high, the phenomenon of parachute soldier rotation.
Description
Technical Field
The utility model belongs to paratrooper umbrella application, especially a novel annular stable speed reducing umbrella.
Background
The stabilizing parachute has the functions of stabilizing and decelerating, namely adjusting the air posture of a parachutist and reducing the parachute opening speed of the main parachute.
When the parachuting speed of the airborne troops is not less than 320km/h, the stable speed reducer is adopted to carry out secondary parachute opening, the parachute opening speed of the main parachute can be reduced to 220km/h, and the parachute opening dynamic load of the main parachute can reach the range which can be borne by a human body. The traditional stable speed-reducing umbrella adopts two plane circular umbrella covers to splice and sew, and after the stable speed-reducing umbrella in the air is decelerated for 4s to 5s, the main umbrella is opened.
The umbrella shape of the existing stable speed-reducing umbrella adopts a plane extension structure, the umbrella cover at the bottom edge is closed, and the projection area is small, so the resistance characteristic is lower and is about 0.7. The existing parachute jumping mode is short in stabilization time and unobvious in rotation phenomenon, and when the parachute jumping mode with high jumping and low opening is adopted, long-time rotation easily causes dizziness of a parachutist, and parachute jumping safety is affected.
Disclosure of Invention
An object of the utility model is to provide a novel annular stable parachute.
Realize the utility model discloses the technical solution of purpose does: a novel annular stable speed-reducing umbrella adopts an umbrella coat which is in an ellipsoidal shape after being sewn, the umbrella coat is in an ellipsoidal shape, one end of a pulling top rope is connected with an umbrella top, the other end of the pulling top rope is connected with a converging point of the umbrella rope, and the umbrella top is pulled downwards through the pulling top rope. The shape of the canopy is 7:10 ellipsoid, namely the shape of a short axis and a long axis which are 7:10 ellipsoid.
Compared with the prior art, the utility model, it is showing the advantage: (1) the ellipsoidal umbrella shape improves the stability of the stabilizing drogue. (2) The resistance coefficient is increased by pulling the umbrella top down.
Drawings
Fig. 1 is a schematic structural view of the shape of the stabilizing umbrella of the present invention.
Figure 2 is a schematic view of the shape of an ellipsoidal canopy.
Detailed Description
The invention is further described with reference to the following figures and examples.
The shape of the stable umbrella canopy of the utility model is shown in figure 1 after being filled, and the shape of the stable umbrella canopy 1 is 7:10 ellipsoid when not pulling the top.
The shape of the stable speed-reducing umbrella canopy 1 is a 7:10 ellipsoid (a part of which is cut), and the structure is shown in figure 2. The ellipsoidal umbrella coat has better stability. The drag top of the stable speed-reducing umbrella is increased by pulling the umbrella top down through the drag top rope 2, one end of the drag top rope 2 is connected with the umbrella top, and the other end is connected with a convergence point of the umbrella rope 3.
When the parachutist jumps at high and opens at low, the posture of the parachutist is stabilized in the air, and the possible autorotation phenomenon is eliminated. The invention improves the resistance characteristic coefficient of the stable deceleration umbrella, and the area of the stable deceleration umbrella is reduced by about 18 percent compared with the common stable umbrella under the condition of achieving the same deceleration effect. The utility model discloses a sew up the back and be the canopy of ellipsoid, aerial stability is high, through the pull-down canopy top, increases the resistance characteristic of stabilizing the parachute, and the resistance characteristic coefficient of canopy multiplicable to 0.85.
The utility model mainly adopts an ellipsoidal canopy structure and a method of pulling down the canopy top, thereby improving the stability of the stable speed-reducing umbrella and increasing the resistance coefficient; the stability of the parachute in the air is improved, and the problems that the paratroopers fall freely for a long time and rotate when the paratroopers jump from high to low in an airborne state can be solved. And the verification of dummy airdrop test and real person trial jump is also carried out, and the verification of the use of a certain type of active-service main battle paratrooper umbrella is also carried out.
