Description

Paragliders

The invention relates to paragliders with a narrow elongated, oval, round or square shape, the have special shape and plug stability and are marked © Have sliding properties?

It is known that through the use of paragliders the rate of descent of a parachute system = load without major material expenditure compared to the commonly used parachutes further reduced and at the same time the maneuverability such a system is considerably improved is · The physical cause for this consists in. ,, that the load capacity of such parachutes sum large or predominantly no longer results from drag forces »but from aerodynamic lift forces, which were caused by gliding in a manner similar to that of a glider

The well-known constructions of paragliders are afflicted with disadvantages · With the paragliders, which have buoyancy canopy farms, can either the advance cannot be fully braked without the parachute canopy losing its stability, or additional stiffeners, such as inflatable tubes or stiffeners, have to be used for stabilization made of solid materials, which significantly increase the weight of the parachute. These carrion

Paraglider wrestling are in their functional mechanism very complicated and accordingly prone to failure, and they also require a lot of effort in manufacturing and maintenance.

Paraglider parachutes, which essentially still have round or triangular canopy shapes, do not require any complicated ones Stabilizing devices; but kick the disadvantage here is that the buoyancy conditions are unfavorable and the advance mostly through StruffitJMgsujsienkujug is produced compared to what one to the above-mentioned sliding fallscairmen with auftr cap shapes with a large number of meshes result in a low feed rate

The purpose of the invention is to eliminate the deficiencies listed

The invention is based on the object of providing a sol ~ to create a paraglider with a buoyant, narrow, elongated or oval canopy j is used, but additional stiffening agents are not required, and at all airspeeds lying between zero and maximum speed has a high form and flight stability.

According to the invention the object is achieved in that the parachute canopy in paragliders with schma ^ elongated or oval shape in the direction perpendicular to the normal flight direction from an air-impermeable Strip of fabric, which mainly performs the load-bearing function, and one at the rear Stabilizing fabric strips attached to the edge. This stabilizing tissue stress

Since low air permeability can be produced, it must then be partially or fully carried out by a Schiita

To reduce the flow resistance can also the outer edge of the stabilizing fabric strip is pulled under the supporting fabric strip, what is achieved by special lines or in connection with the use of frames · By this constructive structure, of course, analogously can also be used on square or round parachutes, the parachute canopy has particularly high shape and flight stability and excellent gliding properties.

According to the present invention, the parachute canopy in the transverse direction A - A consists of two fabrics & strips of different air permeability »Sur Er zeiüztinß ainefi aeyodvu ftmi aalian AuPtviohoe muss äa-r * w / vw_

To further improve the aerodynamic efficiency of such a parachute canopy, it is advantageous to Use profile lines 7 * iu, represented by an example in Pig. 6, which are the supporting gevie » fen 1 give the parachute canopy a suitable profile. Instead of these profile lines 7 can also jQövjebespanten 8, represented by an example in Pig. ί, are used, with the help of which the stabilizing Fabric strip 2 can be pulled more under the supporting fabric strip 1 of the parachute canopy Can · If there are no frames 8, the same arrangement of the stabilizing fabric strip 2 can be achieved by special lines 9. In Fig. 4 and Fig. 5 shows this schematically. In this way the sliding properties become such a case screen further improved by redirecting the flow is also used.

All of these construction principles can of course also be applied to parachute canopies of other shapes, &, B to oval, round or square parachute canopies. " With these parachute canopies, especially those with a small diameter, the use of frames 8 is not absolutely necessary, because two profile lines 7 are usually sufficient to exert the necessary profile-forming effect on the supporting fabric part 1.

The basic principles of the present invention are some examples in Pig. 1 to 8 explained in more detail

Pig. 1 shows an example of the basic structure a narrow, elongated parachute according to the invention

The side flaps 6 tighten the Pallschirisliappe in Transverse direction A - Δ, and the stabilizing strip 2, which is pulled down like a bead on the back, prevents it a V-shaped buckling of the narrow, elongated area of the parachute canopy and gives the Paraglider remarkable plug and gliding properties. This enables, among other things, the speed of advance of the parachute from infinitesimally low or even negative values up to to regulate continuously to the maximum value without that loss of stability® occur.

Various possible arrangements are shown in FIGS of support and stabilization surfaces in such shown on a parachute.

In Fig * 6 and 7 the application of the invention Design features on a parachute of oval shape explained using an example. The rear Suspension lines 3 run from the rear of the slot 5 to the base edge 10 formed by the stabilizing fabric strip 2 and from there it becomes a load two Probilleinen 7 used, which to two Punkton 11 of the supporting fabric strip 1 of the parachute canopy get lost·

In a similar way these features are also applicable to round or square parachute canopies Fig * 8 shows e.g. a spread out round canopy, where two profile lines are used
