FR2482043A1 - Vertical take=off aircraft - has circular aerodynamic frame with feet and air-propulsion drives - Google Patents

Abstract

The vertical take-off aircraft has a circular aerodynamic chassis with top and bottom feet, and one or more air-propulsion units. It can be completely free of any moving parts protruding outwards from it. Removable shutters can be mounted in the feet, in the path of the air jets generated by the propellers, or alternatively the feet can contain compartments with valves giving variable output, for fighting forest fires. The drive can be fixed at any required angle.

Description

 The present invention relates to flying aircraft with vertical takeoff, making it possible to take off vertically or horizontally, to move vertically or horizontally, to be fixed on vertical walls, to land or to land in perilous circumstances, able to transport crews and heavy equipment.

 In devices of this type, the propellers outside the size of the machine are annoying and dangerous for the user, risk of hitting an obstacle.

 On this machine, in the event of impacts, they can only be done on fixed parts, therefore unimportant; no deterioration of the material planned on this subject.

Xi number of grippers in motion, for proper functioning is considerably reduced, in relation to existing devices,
Bulky tail removal; stocky in shape, the machine operates very easily.

 Safety is increased for users, no danger of unprotected moving parts.

 Stability for landing on critical terrain, possibility of fixing on steep or inclined walls.

be
The camouflage of 11 items can be quick and safe.

 This machine moves in the air in any direction, stabilizes, can land in different positions; on steep walls, vacant lots, on rough seas.

 The flying machine comprises a circular chassis or any aerodinamic shape, of low lift, made of light metal of strong resistance. Its propulsion is carried out by one or more propellant turbos attached to the center of the chassis or at the ends, depending on the use of the machine.

The tanks will be inserted into the supports of the adjustable thrusters in order to maintain a constant balance.

The machine has upper and lower legs; in the upper legs can be incorporated cockpit and different compartments; in the lower legs united also compartments will be inserted the function mechanisms for the ballasting of the machine.

The movements of the machine are effected by flaps I5-I6 inserted in the air streams or around a stream of fluid generated by the propellants.

The accompanying drawing illustrates by way of example an embodiment of the machine in accordance with the present description. As shown in FIG. I PL. I and figure 2 PL.I, the machine comprises:
A circular frame I, equipped with a propellant 2, a cockpit 3, propellant mounting assembly serving as a tank 4, four upper feet 5, four lower feet 6, different compartments 7 - 8 - 9 -I0 - II - I2 - 13 - I4, control flaps 15 - 16, doors 17.

This powered assembly has several advantages; designed in this way, the machine will be able to take off vertically, move vertically or horizontally, fix on walls at different angles, either with two of the four lower legs 6, and with the circular beam I; or with them four upper feet 5, and the circular drive I. the doors I7, can be incorporated on each of the upper 5 and lower 6 feet, in order to allow the passage of the users according to the positions of the machine.

In case of chic with the machine, the moving parts: propellant, fins protected by the frame does not risk anything, it is designed for this effect.

Moving the machine through difficult passages poses no problems.

By adding I8 floats, at feet 6, the ditching is identical to the landing.

Said invention can be used for:
National civil deience

- fire department
- air ambulances
- various air transport
- nature protection
National military defense

Mountain rescue
The machine shown in Figure I and 2, is well suited for mountain rescues to recover mountaineers in danger. It will be possible for him to fix himself on the steep walls near the rescue, using his lower or upper feet, depending on the inclination of the wall. Rescuers will be able to exit and return through the corresponding losses.

Shocks caused during rescue by the wind or false maneuvers cannot damage the moving parts protected by the chassis.

Rescue at sea
the machine provided with floats at the lower feet 6, may land on rough seas thanks to its bearing base surface of feet.

Fire department
For the extinction of forest fires, the machine can draw water vertically from water bodies, or from planned reserves supplied by any small watercourse, this to reduce the trajectories. The machine will be able to follow the sinusoids produced by the fire, make a firebreak around a house in danger.

The release can be controlled in flow and stop if necessary.

the water can be replaced by carbon dioxide snow or other product for defense against the hydrocarbon fire.

 maybe built fig. 3 and 4 FL. II, an upper central cSne, serving as a cockpit, a propellant support chassis 3, four propellants 2 (or more) depending on the desired power, a waterproof box 7, for penetration level and flotation, of a truncated lower c8ne 4 serving as a water reservoir, provided with feet 5, for injection of water into the reservoir and discharge of water on the fire. The opening '6, allows the circulation of air to suppress air compression at the time of filling and air depression at the time of release. I1 maybe added a compressor on this opening to increase or decrease the water flow at the time of the release.

The flow rate is also controlled at the time of descent into the product to be loaded, by the weight of the machine, corrected by the valves 2, FIG.5, PL.III; which allows filling. Once the operation is finished, take off the balls I, FIG. 5 PL.III are closed by their own weight, as well as by the pressure of the liquid in the tank, which makes it waterproof.

For the release, it is enough to release from the opening 2, FIG.5 PL.III the ball I, FIG.5, PL.III. in relation to the flow to be obtained by any means allow traction on the axis 3 FIG .5 PL.III which will allow the partial or complete release of the opening, if necessary, the release may be interrupted immediately by practicing the reverse operation which consists in closing the valves.

Air ambulances
Air transport
The machine corresponds to the type of device FIG.I PL.I, adapted to needs.

Nature protection.

 Recovery of vessels in distress; 'mean by this idea, eliminate as much as possible this great plague of time concerning the oil tankers in distress, polluting the seas and the coasts.

 It is conceivable to build a recovery machine, fitted with a boat neck I FIG. 6 PL.IV, empty, rigid, in metal frame, fitted with a control tower 5, water propulsion machinery assembly 6, propeller 7, rudder 8, orientable thrusters 2, all around the hull, two front doors 3, fixed on pivoting axes 9, of hull supports 4, making it possible to consolidate the hull I when empty. The hull supports being disconnected at the time of the penetration of the sinking ship, they offer a resistance allowing centering and support of the ship in question. The design of this machine allows it, thanks to its propulsion to move very quickly on a batten to reach the places of rescue. by winch, after closing the doors, stopping the thrusters, moving the whole by sea.

this machine makes it possible to recover crew, boat, loading and, to avoid any pollution.
