Description

The invention relates to a storage space limitation for storage wing vehicles, the wing with the associated mirror surface forms a storage space open in the direction of travel and the wing outer zone Air ducts with exhaust openings to limit storage space for air compressed by a compressor to form an air curtain.

Such a design is known from GB-PS 11 70 747. This makes it possible to increase the usually small ground clearance and the limited maneuverability improve by turning the .Y-axis of the Vehicle is made possible.

The object of the invention is to limit the storage space of the type mentioned at the beginning improve that a production of an air curtain adapted to the operating conditions and a low power requirement is guaranteed. The solution to this problem is at a storage space limitation of the type mentioned provided according to the invention that the Air ducts with the exhaust openings with the interposition of the compressor via switchable Air supplies can be supplied, the compressor in the starting phase via the air supply with the Environment and in the cruise phase via the air supply with the storage space in the area of the Is connected to the stagnation point on the underside of the wing.

This makes it possible to supply ram air that has already been compressed to the compressor in the cruise flight phase, so that there is a correspondingly low power requirement to provide the air curtain with the required Blow out speed. The air cushion that is building up is not in the start phase impaired.

The drawing shows an embodiment of the storage space delimitation according to the invention of a single-leaf Reservoir wing vehicle shown for water operation. It shows

! · 'I g. 2 shows a section through a wing of the Stiiiiflügclfahrzciigcs in the front area with a Air curtain for cruise and

FIG. 3 shows a representation like FIG. 2 with a Air curtain for the start-up process.

The stowage wing vehicle shown consists of a wing I with a fuselage 2 and is in Triangular plan, with the front edges 3 extending downwards and outwards towards the floats 4 and 5 extend. The trailing edges 6 and 7 of the wing 1 unite at a point near the End of the fuselage. They lie in one plane and form the ίο trailing edges of the water slide ^ if there; device swims in the water. The top of the wing 1 is curved in the usual way like a wing. The underside of the wing i is curved upwards, so that by the forward movement of the Stauflügel vehicle creates an air cushion between the wing 1 and the corresponding mirror surface 8 can, as long as the barrage vehicle is in the water and the rear edges 6 and 7 the seal obtain. The air cushion that is formed creates a dynamic pressure as long as the stowage vehicle is in the Moved floor effect area.

A rudder surface 9 is arranged on the fuselage 2 of the ram vehicle, on which the Rudder 10 is located. A horizontal damping surface 11 is on top of the rudder surface attached, this having an elevator 12. In the front part of the fuselage is a guide gondola 13 and an engine 14 is provided. To ensure roll stability, auxiliary wings 15, 16 are on the floating

} o mern 4, 5 attached and provided with rudder surfaces 17, 18, which allow the control of the bank angle.

To the Staurauin over an air curtain 19

increase and thus achieve a higher flight altitude, are in the area of the wing outer zone

J5 air ducts 20,21 arranged parallel to the Rear edges 6, 7 are guided and are connected to exhaust openings 22. The blown air to Formation of the air curtain 19 is taken from the storage space via an air supply 23 for the cruise flight and via a compressor 24 with corresponding feed lines 25, 26 to the air guide tubes 20, 21 fed. It is useful here to draw in the air from near the stagnation point on the underside of the wing remove. For the starting process, on the other hand, ambient air must be used as intake air via the air supply 28 for the compressor 24 can be used.

The exhaust openings 22 can be controllably closed by means of a flap 27 hinged on one side to the wing I. At the same time, the flap 27 can be used as a beam deflector so that the air curtain 19 can be deflected at an angle λ to the center of the wing for the take-off process and thus contributes to the formation of a superimposed static air cushion. During the cruise, the flap 27 is in the position according to FIG. 2 give ^r eight, so that the air curtain 19 is pushed outwardly. In this case, the compressed air is taken from the storage space via the air supply 23, the built-up air cushion not experiencing any noteworthy negative impairment.

The proposed arrangement enables the storage space to be closed by the formation of the air curtain 19 enlarge and thereby reach a higher flight altitude. At the same time, the greater flight altitude a transverse inclination of the device feasible, wherein the

μ air curtain 19 essentially continues to limit the air cushion.
