Problems solved by technology

This is due to the heavy weight of the propeller blades (approximately 11 tons) so that the centrifugal forces at high RPM become very large and it is not economically viable to design these blades for winds exceeding 25 m / s

Embodiment Construction

[0083] Today's wind turbines include propellers that are driven by airflow (ie, wind). When the wind increases, more kinetic energy can be used to drive the propeller blades, but because the propeller blades are large and heavy (each blade is about 11,000 kg), when the wind speed exceeds a certain level (depending on the strength of the blade and its installation on the shaft) When installing strength), the rotation must be stopped to prevent centrifugal force from damaging the blades. Therefore, the air turbine stops its work, and a lot of wind energy is wasted. On the other hand, when the wind is too weak (approximately 4 m / s or lower), the available kinetic energy is too small to turn the huge air turbine, so the huge propeller cannot be operated. The present invention overcomes these obstacles and explains how to make the air turbine of the present invention compact and generate more electricity in weak and high-speed winds.

[0084] In addition, it is worthwhile to install a ...

Abstract

The invention provides an application and device of air internal energy. A method of converting the internal energy of air into useful kinetic energy based on the flow of air through a generally tapered nozzle which, due to the reduced cross-section of the nozzle, accelerates the air thereby increasing its kinetic energy . The increase in kinetic energy is equal to the decrease in the internal energy (ie temperature) of the air. A turbine is arranged inside the nozzle to convert the kinetic energy of the airflow into mechanical energy, which is converted into electrical energy or transmitted into the gearbox to provide driving torque. Devices using this method can utilize natural wind as the source of air flow or use artificial air flow devices. Devices incorporating means for artificially generating airflow can be used as engines for land and sea vehicles and aircraft. As the air temperature in the nozzle decreases, moisture condensation occurs and liquid water can be stored for further use.

Description

Technical field [0001] The invention relates to a method and a device for increasing the kinetic energy of a gas and generating electrical or mechanical energy through the kinetic energy. Background technique [0002] Nowadays, wind turbines are very common in windy areas. Its design is similar to the propeller of an aircraft. The wind turbine is installed on a high tower facing the natural wind. The natural wind rotates the wind turbine, and the rotation drives the generator to generate electricity. A minimum wind speed of about 4 m / s is required to start the propeller rotation. The electricity generated by the generator is then used by the owner of the wind turbine or delivered to the grid. [0003] A good example of such a product is a product made by a major manufacturer in the field. The following data describes a 2 MW generator. [0004] Diameter: 80 meters [0005] Swept area: 5,027 square meters [0006] Number of blades: 3 [0007] Tower data: [0008] Axle height (appro...
