FR2541732A1 - Compound anemodynamic motor with its applications to propulsion - Google Patents

Abstract

The invention is a wind machine motor consisting of two rotors with coaxial vertical shafts. The external rotor with its twenty four vanes directed at 50 DEG with respect to the radial vertical planes directs, in all azimuths, the wind onto two of the six vanes of the central rotor, the rotation of which, in a specific direction, generates a centrifugal gyrating flow which leads to the rotation of the "stator". The drive force generated is doubled and may be transmitted to a single drive shaft, by a differential bridge. Driving submerged or airborne propellers, or wheels, this motor may serve to propel ships, airships or motor vehicles.

Description

 The present invention relates to a high and high power wind turbine capable of being applied to the 1 drive of ships; of certain land vehicles and, possibly: airships.

 The technique of wind turbines, in the current state of the recl ches and of the solutions proposed, offers a very wide range of i @ tians, in particular as regards the machines with vertical axis, t @ which are best suited to envisaged applications.

In fact, the devices must be operative in all the azimuthal directions of the winds. The giroustte devices are compatible with practical use. The rotors with pivot blades are of delicate construction and of poor performance. Insuff also, is the performance of the blades of the "SAVONIUS" type, due to braking which is exerted on the passive face. The systems with Stator @ d @@ ector weigh down, in pure loss, the turbines and impose a significant reduction in the diameter of the motor rotors, and, consequently , surface activated blades
The motor which has been designed and which is the object of this invention tends to take advantage of a secondary phenomenon of large-scale wind flow generated by the rotation of a rotor arranged co-exally within a second Rotor driven itself by the centriguge fl @ gyratory generated by the first Rotors
Figures I and Z which represent the device in plan and elevation may, graphically, evoke some analogy with certain turbines of previous designs. The principle and the operation of the compound engine set out below are very different.
Indeed, the two Rotors can rotate freely and independently on the vertical axis (1) .- The ssremier has six blades (2), lé rament curba parts vertically on a hub (3) .- The second consists of two circular plates, sorts of spoked wheels (4), inserted on a hub (5) and supporting a flat annular rim (6) .- The lower plate is secured to the upper plate by twenty four rigid blades (7), inserted vertically on the two rims (6). Made of light alloy they are as thin as possible while having a slightly plano-convex section. Gold tee @@ in the direction of rotation, they form an angle of 50 @ av each of the planes radial (N).

 2 - Propulsion of land vehicles.

 Sand yachting enthusiasts have carried out sport cruises either in tropical regions or in Antarctic regions where wind power can be quite efficient.

 Vehicles, sporty monk, but more comfortable, could be propelled by anemodynamic motors, could therefore be useful in certain windy regions of the globe where the penetration of men industrial is in progress. In the drawing of figure 6, the sails shown in dotted lines shows the difference in size, on the roof of the vehicle fitted with a wind engine. To lower the center of gravity, the upper plate (6) was placed halfway up the shaft ( I) .The significant length of the lower main shaft, suitably shouldered inside the body, makes the overhang mechanically satisfactory, which avoids the addition of support tripods, to the benefit of the weight and the 'aesthetic.

 In terms of prospsctive, the return to air navigation by steerable balloons has been the subject of meints projota realistic.

 If, at sea, there is vernt, there is also at high altitude and anemodynamic engines could find a suitable application to propel economically and without the risks of engine @ thermal, these types of aircraft. - Figures 7 and 8 suggest such an application. To reduce the catch from the side winds, the lift is provided by two oblong flutterers, with the same as @ entional force as a single cylinder of double diameter. As for a marine "catamaran", antretoises (26) (27) (28) connect the two balloons, with a rigid frame and inflated with helium, between them. (24) and (25).

 Two motors, of large diameters and reduced heights are placed above and below in the median part of the machine. Each motor drives an aerial propeller. The rotors (22) and (23) turn in opposite directions to neutralize the gyroscopic effect. The mechanical or electrical transmission components are housed in the compartment (29). The aircraft comprises four landing gears (30).

 The dome (33) houses the cockpit and the passengers are housed in the lower part of each balloon in communicating cabins, naturally helium-tight, with portholes (32).

 The landing gears disrupt, by gravity, the stabilization of the flight of the aircraft, the balance and the horizontality being maintained by a gas pressure dispatching valve towards one or
