Abstract

The invention relates to a hydro-aircraft consisting of a hybrid single-shell craft having a large wing area, the lower and/or side and/or rear areas of which include one or more inclined flexible skis or blades. The skis and the wing surfacea lift the craft as it moves forward and maintain the craft above water. Once cruise speed has been reached the skis engage with the crests of the waves and maintain the height as a function of the power supplied by a power unit. Increasing the power makes it possible for the craft to fly.

Description

AEROHIDRONAVE

FIELD OF THE INVENTION.- In ships and aircraft.

STATE OF THE TECHNIQUE.- Current ships have difficulties in reaching high speeds due to the state of the sea, the existence of floating objects and propulsion systems. Improvements have been made with the catamarans, but there are still some drawbacks. The present invention solves or reduces said problems.

OBJECT OF THE INVENTION

Obtain a hybrid vehicle, simple, economical, safe, practical and very high speed, which competes with airplanes over short and medium distances.

Get a vehicle little affected by the waves and the objects that float on the water and that is very stable.

Ensure that the ship's contact with the water is minimal, very slippery and cushioned, especially when the ski is supported at a delayed point very distant from the center of gravity.

Provide a ship that can fly, especially if the state of the sea is very rough, and preferably land in sheltered areas of the coast.

DESCRIPTION OF THE INVENTION.- The aerohydronave of the invention consists of a hybrid monocoque ship with a large alar surface that carries in its lower and / or lateral and / or posterior zone one or more fins and slopes, flexible and inclined, skis and alar surface during the advance of the ship lifts it and keeps it out of the water, once the high cruising speed is achieved, the skis rest on the crests of the waves and maintain the height depending on the power applied by a power group. Increasing the power the ship can fly The lower and lower lateral area of the ship can be covered with sheets or thin rods, flexible and inclined instead of the fins or skis.

The skis can be subdivided by their lower zone into small skis.

The skis can only be placed in the lower and lower rear lateral area of the ship, and they rotate or lean around their attachment point, they can also be placed only in the lower rear area helping to support the ship as an airplane. They can be extended and retracted by means of hydraulic hammers.

The lower area of the skis has a sliding film that reduces frictional resistance with water.

The propulsion can be by gas turbines driving air or by paddle wheels driven by different types of engines, gas turbines, diesel, etc. The system used will depend on the required speed. The air can be propelled inside multiple fins or hollow skis. The air flow in its displacement drags the water increasing the displaced flow and therefore the propelling power. The turbines are placed high and protected from the entry of water through filters. You can also place the wings in high area.

In a third propeller variant, the ship carries in its lower zone three or more uprights or inclined ducts whose interior, by means of a pump or turbine, sucks, stores in a tank and drives the water on which it is sailed or flies over its ends , the suction is carried out through the front area through a grid and the drive through the rear area. It can be used in shaky waters. A variant performs the suction for one amount and sends it for another. The uprights have an aerodynamic profile, of little resistance to the advance. The water outlet is carried out in the form of a water jet through a nozzle, it can also be done through slits or grooves that produce a greater reaction or use of the impulse.

Sensors can detect the height of the ship, acting on the depth controls depending on the state of the sea or water, keeping the ship at a safe height. You can also measure the height of the ship with respect to the crests of the waves and in the same way you act on the controls. In flight, it uses conventional gyroscopic flight systems of airplanes.

The uprights can be tilted by rotating around its upper end, or its central area. They can have a flexible and rotating part. The inclination of the uprights also benefits from the impact with floating objects. The benefit of the present invention, with respect to the rough sea, impact with objects, etc., will be all the greater the larger the dimensions of the ship.

Take advantage of the advantage and ease of propelling air over water, which in turn increases the reaction of the ship.

The lower area of the skis may be covered with longitudinal channels on whose front areas air is blown.

Operation: At rest, the ship is suspended by its hull, as it advances with its thrusters, alar surface and skis, it affects the water creating an upward force that elevates the ship totally or partially from the water depending on the type of solution desired. The ship rises to a height outside the water in which the lift forces are matched with its weight, from that moment the ship moves propelled in the water and supported by the alar surface in the air and the skis in the water, the stabilization is controlled by the fins and by the side skis. The alar lift can be between 70% and 90% and that of the fins or skis in the water between 30% or 10% of the total weight of the ship, so if the ship rises excessively it loses the lift of the skis and descends, staying at an intermediate height in which the total lift always equals the weight of the ship. Increasing the power the ship can fly.
