Definitions

  • Air cushion vehicles are usually provided with a compressor for generating the required air cushion within a rubber apron and with at least one engine for driving straight and / or cornering.
  • the cornering is generally controlled by a lateral deflection of the air jet of the engine.
  • rudders known from aircraft construction are generally used, which are arranged directly in the air jet of the engines.
  • the invention relates to a control and braking device for a hovercraft, which is provided with at least one engine for generating the propulsion, and a compressor for creating an airbag that can be produced beneath the hovercraft, and in which a rowing device is located in the rear area to control the direction of travel.
  • the object is achieved in that in the rear region of the hovercraft there are two large brake flaps which are located next to one another and can be folded out.
  • the brake flaps are assigned directly to the engines and are partially pivotable over the contour of the hovercraft.
  • two engines are arranged in the rear area of the air cushion vehicle, followed by a negative V-tail with associated rudder elements, the rudder elements of the negative V-tail extending diagonally across the outflow openings of the engines.
  • each brake flap coincides with the corresponding pivot axis of the associated rudder element.
  • the rudder element can be placed on the brake flap when it is open. This makes it possible to largely divert the air flow blown out of the engine, so that a thrust reversal occurs.
  • This reversal of thrust can be metered by adjusting the angle of attack of the brake flap and at the same time tracking the rudder element, so that either an increased braking effect adapted to the requirements or a particularly rapid change of direction of the air cushion vehicle is achieved.
  • the reverse thrust also makes it possible to reverse the hovercraft.
  • the invention and its configurations achieve a maneuverability of hovercraft that is almost comparable to the maneuverability of watercraft. This means that the driving safety of hovercraft is significantly improved, especially at higher speeds.
  • the arrangement of the brake flap on the engine according to the invention can in principle also be used in those hovercraft which are only equipped with one engine. In this case there is no possibility of direction control. However, the other advantages of the invention with regard to the significant improvement in braking behavior are also achieved.

  • This thrust reversal of the air jets of the engines 5, 6 also allows the hovercraft to move backwards in a targeted manner without further ado.

Abstract

La présente invention concerne un dispositif de direction et de freinage pour véhicule à coussin d'air comportant au moins un moteur pour la propulsion et un compresseur pour la création d'un coussin d'air au-dessous du véhicule, un dispositif de gouvernail commandant le sens de la marche étant disposé à l'arrière. Le but de l'invention est de créer un dispositif de direction et de freinage pour véhicule à coussin d'air, permettant d'effectuer des changements de direction ou man÷uvres d'évitement très rapides, ou des freinages rapides. Cette invention est caractérisée par la présence, à l'arrière du véhicule à coussin d'air, de deux aérofreins de grande surface juxtaposées et pivotants (16, 17) directement associés aux moteurs (5, 6). La moitié supérieure arrière du carter (7; 8) de chaque moteur (5, 6) est conçue comme aérofrein pivotant (16; 17), la partie arrière de l'aérofrein (16; 17) étant articulée, de façon à pouvoir pivoter, sur la caisse (1) du véhicule à coussin d'air.
