The invention relates to wind energy and shipbuilding concerns the construction of the rotor and the traction and control devices, and wind turbines that use the Magnus effect. The technical result consists in increasing lift at 30-50% expanding direction control capabilities and reducing the lift on the rotor energy input provided by the fact that in the composite type Magnus rotor comprising a cylinder and the end plates according to the invention, the cylinder formed of several cylindrical bodies with a height equal to the height of the cylinder, each of the bodies has a side closed shell rotatable body secured to the end plates, the rotor is provided with a vane and can rotate around its central longitudinal axis, and between the cylindrical bodies along their entire length in front part of the rotor and flow dividers are placed in the rear part - otvoditeli stream.
DESCRIPTION OF THE INVENTION
The invention relates to shipbuilding and wind energy, and concerns the construction of the rotor and traction control devices, and wind turbines that use the Magnus effect. It allows to increase the lift force is not less than 30-50%, the possibility to extend the direction control lift, lower energy cost to operate the equipment.
Known adopted a prototype rotor Magnus, comprising a cylinder and end plates (YS Kryuchkov and other wings of the oceans -.. L .: Shipbuilding, 1983, p. 158).
Prototype Disadvantages: relatively small lifting force and high energy consumption in the cylinder rotation.
The technical result of the device - an increase of lift by 30-50%, the extension direction of the management capabilities of lift, lower energy costs for rotation of the rotor.
The technical result is reached by that in an apparatus comprising a cylinder and the end plates, the cylinder is made of multiple cylindrical bodies with a height equal to the height of the cylinder, each of the bodies has a side closed shell rotatable body secured to the end plates, the rotor is provided with a vane and can rotated about its central longitudinal axis, and between the cylindrical bodies along their entire length in front (bow) of the rotor placed in the flow dividers and rear - otvoditeli stream.
It is known that Magnus lift rotor and perpendicular to the direction of flow is
R = 
2xV 2 SC y
where V - flow rate; S - area of the diametrical section of the cylinder; With in - the lift coefficient. In particular, C = 8.10 in the cylinder at a linear velocity of rotation V sp = (3-4) V. With further increase due to increase in V bp, usually not economically feasible, it requires energy to rotor disproportionately increase in C. The lifting force is generated due to the pressure difference (vacuum) from the stream to the left and right halves of the cylinder. The pressure pa left half proportional to (V + V bp)2, and on the right - the value (V BP -V) 2.

The proposed rotor (for example, in Figure 1) rotational speed for different parts of the rotor are independent from each other, unlike the Magnus rotor, so therefore can be matched to the vacuum pressure on the right side is equal to the bullet, depression and on the left - maximum technically feasible. In this case, the lifting force will be proportional to the rotor R max = (V + V levbp)2, where vr V lev - speed of the left shell of the body. The claimed device differs from the prototype in that: 2. Each side has a cylindrical body closed flexible envelope rotatably - move in a closed circuit. 3. The cylindrical body attached to the end plate. 4. The rotor has a feathered device and can be rotated around the central longitudinal axis of the rotor. 5. At the front (fore) of the rotor over the entire length of cylindrical bodies placed incoming flow divider. 6. At the rear (aft) of the rotor over the entire length of cylindrical bodies fitted otvoditeli flow. Other close analogues were found. The device illustrated by a drawing, which shows a composite rotor (side view) and its cross-section. The device 1 comprises two end plates, the cylindrical body 3 side shell 4 in the closed bodies 3, vane 5, 6, a central longitudinal axis, the flow divider 7, otvoditel stream 8, rollers 9, the base 10. |
The device operates as follows. The device 1 will be stirred to their base 10, such as a vehicle. With wind vane rotor 5 is rotated around the central longitudinal axis 6 and is set in the direction of fluid flow (air and water). The incident on the rotor 7 divider splits the flow, at the same time depending on the shape divider, flow around cylindrical body, will create the velocity field and pressure conducive to increase the lifting force of the rotor. Side sheath 4 on cylindrical bodies 3 are rotated counterclockwise (drive not shown) using, for example, the rollers 9 themselves body secured to the end plate 2 and thus remain stationary. At the same time for maximum lifting force linear speed of rotation of the right body is selected from the condition that the vacuum pressure on the body, and the rotation speed is given as much as possible to the left of the body. 8 provides a flow Otvoditel mainly the smallest resistance of the rotor and increases the lifting force of the rotor.
Prikidochnye evaluation show that the linear left body shell rotation speed equal to 3/4 the velocity of flow, the rotor lift increase to 33-50%. It can be assumed that the energy consumption for rotating the rotor proposed skins compared to the energy required to rotate the rotor Magnus cylinders to be several times smaller.
If you have more than two cylindrical bodies through proper allocation of bodies and their forms, and selecting appropriate rotation speeds possible to change the direction and created lift.
