HELICOPTER WITH CIRCULAR ROTOR ARRANGEMENT
Document Type and Number:
WIPO Patent Application WO/2008/141401
Kind Code:
A1
Abstract:
Synthetized helicopter, concerns of a vehicle, the most simple as possible, which uses various protected lateral helix, instead of only one, great and very big above it, normally called propeller, seen in a common and conventional helicopter. These helix around it can be replaced by jets, above or/and the side, for propelling and direction. It uses some light metal or fibre, light and resistant. Its principal objective is to make the flight much more simple, specially because it has many helix around it, in substitution of the great propeller above the vehicle, and this simplicity makes it easy to be driven by person, to be in need for this only a few controls from the driving cabin, making it possible to go up and down in anywhere.

CLAIMS

SYNTHETIZED HELICOPTER, characterized to be a simple vehicle that can raise in the air with the help of many propelling little helices in substitution of the great propeller above any common helicopter, but in this case these helices can be substituted by jets feed by proper fuels. In this project nothing is predetermined, not even the size of the helices, the jets, or the size of the body of the vehicle, or the exact form of it, since this body (or driving cabin), can be round or on plan sides, in square, hexagon, octagon shape, etc. It can be metallic or some kind of light and strong fibre. It is fixed only the idea of the vehicle lifting in the air, somehow like conventional helicopter, but with the great difference of not having the great helix (propeller) above, let's emphasize. So, it's characterized to have many helices, or jets, installed around, instead of only one above (propeller). Its assembling, or mounting, is in concordance with the basic necessity, and basic idea. Some cramps, fixers, and mechanic supports have not been represented here to be traditional and mechanic principles, known by any mechanist. This project is characterized, also, to have its helices protected against any possible personal accidents. It is characterized also by the fact that all its lateral helices, or jets, must be upper the central gravitational point of the vehicle, to set up its well balanced situation into the air. It is characterized also by its facility of getting up or down, lifting or descending, evem among trees, for the reason of not having the great and above propeller.

Description:

helicopter with circular rotor arrangement

solicitation of patent of invention of an apparatus, a vehicle similar to a conventional helicopter, with the difference of not having the helix above, normal on a common helicopter, and having an extremely and secure mobility. The description of working operation of this apparatus (vehicle) is the following: FIGURE 01 - This figure shows the principles of working operation of the synthetized helicopter. This consists of a vehicle built in fibre or metal, modern and light elements, what is much important, having around it several helices revolving to provoke a flux, a flowing of air down, propelling the vehicle up without the great helix required on a normal helicopter, helix this normally called propeller. In this figure (01) the arrow 02 shows the vehicle itself. It consists of a wrapper made of light fibre or metal. Its size is not specified, since it can be built in accordance with each necessity. Here it is shown internally with a space enough for one person. The arrow 03 shows the door of the vehicle, to get inside it. The arrow 01 shows arrows that represent the course of the wind generated by the helices around the vehicle (04), and the helix 06, above, which impels and drive the vehicle. The arrow 05 represents a support and connection through which passes the axes and controls to the helix 06. FIGURE 02. This figure shows the same vehicle, with more explanatory details. In it, the arrow 02 shows again the vehicle itself. The arrow 08 shows a seat inside the vehicle, where the driver sits down in front of the controls which can be seen in front and below the seat. The arrow 07 shows the motor of the vehicle. 17 shows a gear box to connect the gyrating axis that comes from the motor to the helix (12) of direction for the vehicle, 14 shows two gearings connected in 90° to transmit the gyrating movement of an axis that comes from the motor and lead to the helix 12, above the vehicle. The arrow 13 shows a "knee" of gears, just as the same in 14, and these, with the purpose of leading the movement from the motor to all the helices around the vehicle, here represented by only two of them, at the left (15) and at the right (also 15) of the vehicle. This "knee" of gears at 90° is represented more clearly at the right of the vehicle (13 and 14). 05 shows the axis used to move the helix 12, to move and drive of the vehicle, through another "knee" of gears, like 14. 06 shows the axis used to transmit the movement of the motor to many helix all around the vehicle, and represented only by the helix 15, at the left and the right of the vehicle. 10, at the right and the left, show two of the many axes of the helices around the vehicle, a good number of them, as they can be seen at the figures 03 and 04. The number 10 shows, too, the central axis, which moves all the lateral helices. The arrows 11, at the left and the right, represent little gears fixed at the central axis (10) to gyrate the

helices 15 all around the vehicle. These little gears (11) are moved by the greater gear (09) fixed at the central axis. This axis and these gears are fixed at the gear 16, which is moved by the little gear (18) that moves with the movement of the axis 06. FIGURE 03 AND FIGURE 04. - These figures show the synthetized helicopter seen from above. The arrow 02, in both figures, shows the body of the helicopter,itself and exactly. In the figure 03, this body is round. The figure 04 shows that this body can be done with sides (flanks). In this case it has 08 sides (flanks), but it can have more or less than this number of sides. The arrow 01, in both figure, shows circles around the body of the helicopter. They are not circles, really. But theses represent the gyratory movement of the helixinas around the body to make it lift like a common helicopter, what is the aim of this demand for a patent. Thus, these circles are helices fixed in the outside of the apparatus. The arrow 04 shows the great gearing, or an iron chain, similar to those used in bicycles, used to transmit the gyrating movement from the motor (IN THIS

CASE) to the helices (Ol).The arrow 05 shows the supports, made to support and fix these helices around the helicopter. The arrow 03 shows a protection of metal or steel wire screen around the helices, to protect against personal accident, in the case of touching them. A wire screen or light metal sheet. FIGURE 05. - This figure shows too the body of the helicopter seen from above, but with an appendix (04) that represents the protection support for the helix 05, which will impel and drive the vehicle, while it will be elevated in the air. In this figure the arrow 01 shows the round body, as meant before, the arrow 02 shows the protection in wire screen or steel sheet, for the helix all round the body of the vehicle. The arrow 03 show the movement in semicircle that the appendix of the helix 05 can make to produce the direction to the vehicle. FIGURE 06 - This figure shows the helix, above the helicopter, what guides and impels it. The arrow 01 shows the body of the appendix meant before, a tube, a conduct to protect the axes 02 and 09 - This appendix is fixed at the body of the helicopter. The arrow 02 shows part of the axis (arrow 08), what brings the gyrating movement from the motor. The arrow 03 brings the movement of the internal controls of the vehicle; This movement and control is due to make the drive helix 05 turn to right or to the left, or to ahead, and in this case to propel the vehicle. 06 is the axis for the helix 05. The many other arrows gearings in 90°, or "knees" to transmit the internal movement to the helix 05. These "knees" already detailed in the figure 02. Next to the axis 06 of the helix 05 are used two "knees" to receive by this helix the gyrating movement coming from the motor, and at the same time the driving movement conducted by the "knee" seen just below, next to the segment 09 (segment of axis showed by the arrow 03. This segment 09

(and axis 02) bring the control for driving from inside the vehicle. This movement is shown by the arrow 04.

FIGURE 07 - This figure shows again the body of the synthetized helicopter seen from above, without the driving and propel helix. In this figure the arrow 01 indicates the protection for the helix against personal accidents. In this case only two of them are represented, but there are many of them around the vehicle. 02 represents one of them; 03 represents the central and great gearing, here seen with some drawings of "teeth" in part of it, but theses "teeth" are all around it. This gearing moves the gears (11) and (02) and all of those that round the helicopter. 07 shows one of the emptying (cut away, curved) of the central gearing, to make it the lighter as possible.

FIGURE 08 - This figure shows one of the supports for the helix around the body of the synthetized helicopter. 06 represents the support itself and properly. 05 represents the axis of the helix, seen here in perspective, showing its peels. 08 represents the little gear, fixed at the axis 05. 09 represents a little segment of the great and central gear (arrow 03 of the figure 07) gear this which transmits the gyrating movement from the helicopter.

FIGURE 09 - This figure shows the synthetized helicopter without the direction and propel helix from above the vehicle, but shows two other helix with the same purpose at the side and next to the many helix that round the vehicle. These two helices 01 can work independently from each other. It means, while one of them gyrates its peels in one direction, the other can make it at the opposite course, putting the frontal side of the vehicle at one determinate direction (ahead). After this, both can work in the same direction, propelling the helicopter ahead, and in the desired way (or direction). In this case, the arrow 01 shows a protection for this helix (02).

FIGURE 10 - In this figure, it's seen one of the lateral propeller after the one which is fixed above, seen in previous figures. In this propeller/dirigible helix (since the other one is in the other side of the body of the synthetized helicopter) it is seen the protection in a tube shape (01) to protect against a possible personal accident with the helix (02). 04 represents the helix of the dirigible propeller. 05 represents the protection for all the lateral helix. This is made of a steel sheet or a wire screen in which are fixed all the lateral dirigible propellers. FIGURE 11 — This figure treats of a mechanism that can be next to the gearing box, which connects the movement from the motor to the dirigible helix, on the top of the helicopter, as seen in the figure 02. In this figure (02) the gearing box is the arrow 17. The mechanism in the figure 11 is good to accelerate the rotation of the dirigible helix. It's a cone fixed to an axis, seen in the smaller figure (07), together the figure 11, and below it The axis 03 receives, through the gearing

box (not shown internally here to be a traditional mechanism, known by any mechanist). The force and movement from the motor, and gyrates with it. A smaller wheel receives this gyrating movement and transmits it through the axis 04 to the dirigible helix. The material used in these two pieces have to be suitable. If the cone is made of metal, the one of the wheel must be of rubber, or some plastic, in order to be suitable to each other and change the movement to the axis 04. Through an arc or a "fork" (06), commanded from inside the driving cabin by the pilot, the wheel 05 is able to slip along the axis 04, and clung together to this, making it gyrate together, and transmit the movement, bigger or smaller, to the dirigible helix, provoking on it a small or a big propelling. So, the axis 04 gyrates slower or quicker, as the wheelO5 slips to the part of bigger or smaller diameter of the cone 01, just as it is possible to be seen by the arrows A and B. The arrow 02 represent supports for or of the axis 03 of the cone, and the arrow 08 represents supports to fix the axis 04, which takes the movement, bigger or smaller, to the dirigible helix.
