Description

The present invention relates to an apparatus for transporting people or goods provided with means of air propulsion and capable of moving over the surface of a body of water.

There are already known devices of this type such as hydrofoils and hydrofoils.

The latter are generally designed as boats fitted with hulls floating on water at rest and capable of moving on or just above the surface of the water.

However, these known devices, in order to be able to hover in difficult conditions due to the surface state of the water surface, in rough seas eas for example, call upon complex structures and organs and expensive. In any event, their displacement can only take place within certain limits of the surface state of the water body
The present invention relates to an alternative embodiment of such devices capable of numerous applications and whose performance is at least equal to that of known devices, without increasing the structure and therefore the cost thereof.

To this end, according to the invention, the apparatus for transporting people or goods provided with aerial propulsion means, composed of at least one fuselage and a supporting structure made up of at least two pairs of wings arranged symmetrically with respect to the fuselage, the distal ends of the wings of each pair being connected to a common lateral tapered body, said apparatus being associated with support means allowing it to move over and rest on an aquatic surface, is characterized in that that said support means consist of at least three floats forming a lift base, at least two of which are constituted by the tapered lateral bodies integral with the distal ends of the wings and in that each pair of shafts is movable in rotation and deformable relative to the fuselage and is associated with damping and return means
Thus, the device is capable of moving on a body of water almost regardless of the surface condition thereof. Indeed, thanks to the articulated and damped connection of the lateral common bodies (by which the device carries on the water), the device is capable of absorbing the shocks due to the waves. In the case of significant differences in level, the device can even ricochet on the water.

In addition, the profile of the lateral tapered bodies is designed so as to have the maximum lateral lift and minimum resistance to advancement.

In order to increase the flexibility of the supporting structure and therefore the possibilities of shock absorption, the wings are articulated on the fuselage. The root joints can also be associated with damping and return means.

Preferably, the distal ends of the wings are articulated on the corresponding common body along two distinct axes of articulation, parallel and vertically offset.

The supporting structure then presents from the front, on each side of the fuselage, the shape of a quadrilateral.

According to a preferred embodiment, the damping and return means are associated with the articulations of the two lateral bodies on the corresponding wings.

Advantageously, the damping and return means associated with the tapered lateral bodies are arranged, for each pair of wings, on the outside of the corresponding articulation relative to the wings.

This arrangement makes it possible to obtain better damping conditions and deformability of the structure.

Similarly, the front carrying body is articulated on at least one vertical leg secured to the front of the fuselage, and the damping and return means are arranged, for example behind the axis of articulation.
Preferably, the lateral and front tapered bodies form a support plane on the aquatic surface, substantially horizontal when the machine is stationary on a body of water.

In order to achieve good performance, particularly with regard to the stability of the device, while reducing friction during the flow of water, the lateral and front tapered bodies are of substantially flat and elongated shape with an axis aligned with the aerodynamic flow, the lateral bodies being inclined relative to the vertical, the front body being substantially horizontal and provided with a stabilizing keel.

The apparatus according to the invention is also capable of flying by taking off from the water without radical transformation of its structure, the latter being for this purpose formed of lift wings making it possible to ensure the lift necessary for the evolution of said device in the air.

 I1 is possible to design this structure of temptation so that below a given speed of advancement, the apparatus moves on the surface of the water like a hydrofoil or a hydrofoil and that beyond this speed limit, the aircraft takes off and flies in the manner of an aircraft.

In order to adapt the apparatus more completely to the flight, it comprises means for adjusting the dihedral formed by the wings and the fuselage in the plane of rotation.

The invention will be clearly understood in the light of the accompanying drawings.

Figures 1, 2 and 3 schematically show an embodiment of an apparatus according to the present invention, respectively in plan view from the side, and from the front.

Figure 4 shows schematically from the side the lifting principle of the device according to the invention.

Figure 5 is a diagram showing the principle of deformation of one of the wing structures of said apparatus.

The apparatus in 1 exemplary embodiment presently described; is of the type provided with a supporting structure made up of two superimposed wings. On each side of the fuselage 1 are arranged two wings 2, 3, 4 and 5. The distal ends of each pair of wings are integral with a lateral body common to each pair and bearing the respective references 6 and 7. In each pair wing, one wing is secured to the fuselage in the lower part thereof, while the other wing is connected to the upper part of the fuselage and behind the lower front wing in the direction of the nut - also air. In front view, the wings of a couple, the lateral bodies and the fuselage thus form a sort of quadrilateral.

The aircraft is provided at the front of its fuselage with two fins 8 and 9; propulsion means 10 are arranged in the rear near the tail.

The apparatus according to the invention is designed as a hydroplane or a hydrofoil resting on a body of water and liable to move on the surface thereof.

To this end, the device comprises three support bodies made up of floats and making it possible to support the device when it is on the surface of a body of water; - two of these floats are formed by the lateral bodies 6 and 7 disposed at the distal ends of each pair of wings, while the third float is constituted by an additional body 11 before and has substantially at the front end of the fuselage.

According to a feature of the invention, the lateral thrust bodies 6 and 7 are mounted articulated on the wings.

Preferably, the front body 11 is also mounted articulated on the front legs 12 secured to the fuselage nose 1 as shown in the appended figures. Return means 13, 14, 15, 16, 17, made up of suspension elements, are associated with the articulations between the floats 6, 7, 11 and respectively the wings and the legs 12.

These return and damping means 9 are formed of springs and hydraulic dampers for example.

It will be understood that thanks to the deformable structure and having great elasticity, the apparatus thus produced is capable of withstanding the stresses due to waves during its movement over the water.

The apparatus is designed so as to constitute a hydrofoil or a hydrofoil. In this case, the wings do not constitute lifting elements properly speaking, but can be used for the purpose of taking up part of the weight of the fuselage and of controlling the stability of the trajectory, and finally as a means of suspension.

In this hypothesis, the wingspan, the thickness and the depth of the wings are no longer determining criteria and it is possible to design such an apparatus whose main function would be to ricochet on the water by means of the floats 6, 7 and associated with the absorbing means
Of course, this device can fly if the wings have been designed for this purpose and if the speed reached is sufficient.

When moving on the surface of the body of water, lateral stability is ensured by the joints and the suspension members associated with the parallelogram constituted by the lateral floats and the wings; the longitudinal stability is ensured by the front suspension and the adjustment of the stabilizing front fins 8 and 9, the lateral float bodies 6 and 7 (as well as the submerged keel with which the front float 11 is provided) ensure the continuity of the trajectory followed by the hydrofoil or hydrofoil.

At high speed, the aquaplanning effects are coupled with a lift effect of the lower and upper profiled wings of each pair of wings. Stability at high speed is obtained by a cone effect generated by the aerodynamic lift of the front wings and ailerons, and by the aquaplanning effects giving the horizontal reference and damped by the suspension devices provided for this purpose. adjustment of the devices allowing great stability at high speed can be either fixed during manufacture, or modulated using a servo pilot associated with a gyroscope for example, so as to allow a high speed movement in ricochets in a safe and stable
The apparatus according to the invention can also be designed in the form of a seaplane, therefore capable of flying and taking off and landing on a water surface.
To this end, the wings of the supporting structure are produced in the form of lift wings.
Preferably, the wings are such that the values of the moment of inertia and of the lift, both varying as a function of the longitudinal distance along the wing, are maximum in a zone of the wing other than at the root .

Such wings were described in the French brevei application in the name of the applicant filed on March 9, 1982 under the number 82 03 961.

The wings can be mounted articulated on the fuselage of the aircraft, so that each pair of wings forms with the corresponding float element a deformable parallelogram whose deformation movements are limited by the suspension means arranged either in the vicinity of the float elements as already described, either by means of diagonal shrouds or any other device capable of limiting in damping the deformations of the parallelogram (constituted by the wings and the lateral bodies 6 e 7) due to impacts during landing and / or takeoff
The lift wings are advantageously made @ so that below a certain speed limit the apparatus cannot take off, thus evolving on the surface of the water like a hydrofoil or an airboat, while beyond the speed limit, the lift effect is sufficient to cause the aircraft to take off, then flying like a seaplane.

In order to improve the flight performance of the aircraft, the latter includes means for adjusting the inclination of the wings relative to the fuselage in the plane of rotation. These means are actuated just after takeoff for example and allow the shape of the deformable parallelogram formed by the supporting structure to be modified and this deformation to be maintained in a given position. The adjustment is for example made possible by means of means oleo-pneumatic type variable damping
In the case where the wings are articulated on the fuselage, and the fact that their other end is also articulated on the lateral float element, it is desirable to provide additional damping means and / or stiffeners associated with the articulations of the wings on the fuselage in order to avoid too pronounced deformation of the parallelogram formed by the support structure.

FIG. 5 very schematically shows in front view the possibility of deformation of one of the pairs of wings of the hydrofoil or hydrofoil, in response to the stresses due to the waves (low position) and in the phase of high speed flight (high position).

Also, according to an alternative embodiment of the apparatus, the wings are fixedly secured to the fuselage, that is to say without freedom of movement.

In this case, the own elasticity of each wing can be modulated if necessary by associating their own elasticity with the suspension means arranged at the joints between the wings and the corresponding float element, to ensure a deformation of the structure of the corresponding wings and in order thus allowing a suspension effect capable of responding to the stresses due to the waves or to the forces during the landing (seaplane).

It may be advantageous, in the case where the wings are rigidly linked to the fuselage a to provide elastic suspension means allowing limited relative movement of each wing relative to the fuselage
These elastic suspension means consist for example of a cylinder in which a piston is able to move (integral with a rod connected to the wing) against a spring, for example, deformable for a force given The cylinder chamber can also be connected to a hydraulic or hydro-pneumatic pressure circuit.

It is also possible to provide means of high banners capable of reinforcing the structure of the wings, in particular in the case where this structure is articulated on the fuselage.
Of course, the invention is not limited to the appended drawings and to the description which accompanies them, but on the contrary covers all variant embodiments
In particular, the lower and upper wings can be superimposed or offset one on the other forwards or backwards with respect to the air flow.

The means of suspension can be associated not with the lateral floats, but with the articulations of the wings relative to the fuselage
The device is likely to be amphible, the floaters then being fitted with retractable wheels
The figures show a preferred embodiment of said floaters of elongated shape with an axis parallel to the flow and substantially planar. This adjoining makes it possible to ensure increased lateral stability due to the original inclination of the plane of the body with respect to the horizontal.

In addition, the damping means 17 associated with the tapered front body li can be arranged, either forward or backward (as shown in the figures), of the axis of articulation of said body 11 on the front legs 12.

In the case where the structure comprises shrouds, the return damping means 13, 14, 15, 16 corresponding to each pair of wings, are associated with the shrouds, the length of which then varies to allow the deformation of the structure. The shrouds can also be designed to participate in the lift in the event of a device capable of flying
The apparatus according to the invention is likely to comprise several pairs of wings on each side of the fuselage, as shown in FIG. 6. In this embodiment, the single front body disposed under the fuselage is not essential, stability on the water (or the ground) being ensured by the front side bodies associated with the rear side bodies.

Similarly, as shown in FIG. 7, the apparatus can consist of two parallel fuselages 22, 23, connected by crosspieces 24, 25, of lift or not, and on the outside of which are arranged pairs of wings as previously described.

It should be noted, with reference to FIG. 5, that the deformation of each pair of wings, causes a variation in the inclination of the corresponding lateral tapered body (in the hypothesis of the figures where the two wings of each pair are of unequal length and the lateral bodies are inclined).

In the low position (P1 or P2), the tapered lateral body 7, referenced respectively 71 and 72, is inclined on the horizontal, that is to say on the surface of the water, thereby ensuring that the device, when moving over the water surface, satisfactory lateral stability. The positions P1 and P2 correspond to the responses of the structure to the stresses of the waves in the phase of displacement on water (hydrofoil or hydrofoil) or landing (seaplane).

The high position P3 corresponds to the flight phase (seaplane), the lateral tapered body 7 (referenced 73) is, in this configuration of the wing structure, almost horizontal, thus adding its intrinsic lift properties to those of the structure of wings.

Advantageously, the apparatus comprises means for placing in the high or low position, and relative blocking around in the selected position a in order to allow a slight movement around said position. This relative blocking is such that it allows for example in the low position (hydrofoil, hydrofoil) the deformation of the structure a and in the high flight position a small deflection.

The front body 11 may be constituted by a floating body provided with means for detecting and measuring the acceleration, which is a function of the force of the impacts received by said corE and therefore by the device a and connected to the adjustment means. in position of the articulated wing structures in order to ensure an optimal configuration of these according to the importance of the shocks and the angle of incidence of the waves on the device.

According to the embodiment shown in Figures 6 and 7, it is advantageous to design the fuselage or fuselages as a succession of elongated modules assembled to each other and forming the fuselage so as to ensure aerodynamic and mechanical continuity of the latter. .

This gives great flexibility in manufacturing and use.
