Definitions
- the present invention relates to a lift turbine system that generates aerodynamic lift using a blade and converts the generated lift into a rotational force to turn a generator, and more particularly to a lift turbine system using a wide wing span of a two-dimensional blade.
- the inventor has filed a lift energy system with PCT application date, May 12, 2000, PCT application number PCTZ JP 00/03047.
- One energy source of this lift energy system is a lift tarpin system that drives an automatic rotor to advance in the atmosphere and causes autorotation with lift that acts on the wing, and turns the generator with the resulting torque.
- This lift turbine has many advantages such as 10,000 times the capacity of a wind turbine, and the ability to simultaneously produce and supply clean power, and is expected for early commercialization.
- fixed wings are also widely used, and the main wing of an aircraft is a fixed wing.
- the advantage of fixed wings is that a wide wing, a large wing area, and high-speed motion generate a large amount of lift.
- the wing of an airplane is a lifting device that lifts the airframe and heavy objects, so the wing is used horizontally to generate upward lift, but when using the wing as a lift generating device other than for flight purposes, lift is It is possible to generate in the horizontal direction and convert the generated lift into a rotational force.
- the present invention aims to provide a fixed blade utilization lift turbine system focusing on the lift mass generation capability of an aircraft wing, and to provide it as an energy source of a lift energy system together with a rotary blade utilization lift turbine of the prior application. Disclosure of the invention
- the fixed wing of the wing of a fixed wing aircraft is vertically erected, and the upper and lower sides of the wing are fixed to the ceiling and floor of the wind tunnel to form a two-dimensional wing,
- Two-dimensional bladed turbines having a two-dimensional design, and a number of cyclical Gottingen type wind tunnels including a turbine blade and a fan in a wind tunnel, an annular wind tunnel arranged in an annular shape, a lifting turbine and a ring wind tunnel are suspended and fixed.
- It consists of a rotating frame that rotates horizontally around the central axis, a gear mechanism, a generator mechanism, and an operation control mechanism, and it circulates with a strong wind with a blower and blows a strong wind at the wing leading edge. It is a two-dimensional wing lift turbine system characterized by generating lift in the same tangential direction, rotating a bin, rotating the generator with the torque obtained, and generating electricity.
- Two-dimensional wings are used in the present invention. Two-dimensional wings with infinitely long wings do not exist in reality, but in a wind tunnel, they can create conditions close to that. This wing is called a two-dimensional wing, and the wing of an airplane with a finite wing width is called a three-dimensional wing. Comparing the two-dimensional and three-dimensional wings, there is no essential difference in achieving the lift coefficient, but there is a critical difference in terms of airflow turbulence and drag. In two-dimensional wings, theoretically there is no induced drag due to trailing vortices and lifting forces due to tip vortices that can not be avoided with three-dimensional wings.
- the lift force divided by the drag force ie, the lift-to-drag ratio
- the lift-drag ratio of this two-dimensional wing is much larger than that of a three-dimensional wing, and it is only a wing that does not have an airframe or tail wing that increases resistance, so the lift-drag ratio is even larger.
- the absence of turbulence in the air flow around the wing of the two-dimensional wing can reduce the cross-sectional area of the wind tunnel, and the air flow rate is inversely proportional to the cross-sectional area.
- the lift force L acting on the fixed wing can be obtained by the following equation.
- Airspeed is the air velocity created by the blower and the speed increasing device, and corresponds to the flight speed of the aircraft.
- the plane In order to fly, the plane must be propelled by a jet engine or propeller, but in the present invention, the wind created by the blower is that, and the input is the horsepower of an electric or hydraulic motor.
- the torque obtained by this two-dimensional wing lifting power bin is the product of the lift generated on each wing and the arm length of the couple, and the product of the number of wings. Also, the power factor is the product of torque and angular velocity.
- the amount of lift generated on the turbine blades is large compared to the total amount of output when dozens of airplanes are simultaneously operating, and because the couple arm of the turbine is long, the torque obtained is very large.
- Fig. 1 shows the entire configuration, in which 11A is a longitudinal sectional view and 11B is a transverse sectional view.
- Fig. 1 _A 1 1 B is the rotating frame 2 that rotates horizontally around the fixed central axis 1
- An annular wind tunnel 3 is suspended, and a two-dimensional wing is fixedly installed in the straight wind path of the wind tunnel, and it is shown that a tarpin is formed in an annular shape.
- the Göttingen-type wind tunnel 3 is a circulating system consisting of a straight air path and a curved air path, and a two-dimensional wing 4 and a speed increasing device 5 in the straight air path, and a blower 6 and a blower 6 in the curved air path. It has a guide vane 7 and built-in.
- the straight air paths are all radially directed to the central axis, and the air flow is also radial.
- the blower 6 illustrates the case where the axial fan is taken in the longitudinal direction, and the longitudinal air path is divided by several horizontal walls.
- the two-dimensional wing 4 is turned to the left and right as shown in Fig. 1B, because the circulating flow is always received at the wing leading edge to generate lift in the same tangential direction. Both wings are located at equal distances from the center of pressure.
- Fig. 1B shows the case where one wing is placed in the straight air path, but it can be increased to two or three.
- the mechanisms that make up this system are all made of lightweight materials and are made extremely lightweight.
- the gear mechanism 8 and the power generation mechanism 9 which are heavy objects are fixed near the central axis, and the operation control mechanism 10 is installed on the ground.
- the present invention generates a large amount of lift using a large number of two-dimensional blades, converts the generated lift into a rotational force and turns the generator, and generates power without combustion, clean, no fuel, and very low cost. It can be mass-produced and supplied, and it can be used to protect the global environment and solve energy problems.
