Airfoil and a Turbine Apparatus

NºPublicación: US2019257288A1 22/08/2019

Solicitante:

CAREN MEICNIC TEORANTA [IE]

KR_20190079649_A

Resumen de: US2019257288A1

The present invention provides a turbine airfoil for relative movement in an ambient fluid, and a turbine apparatus comprising at least one airfoil. The airfoil comprises a main spar having two hill formations and discharge means operable to discharge evaporative and condensing fluids outwardly into the ambient fluid flowing over the main spar. The first of these hill formations accelerates the flow of the ambient fluid until it reaches the speed of sound. After the first hill formation the Mach number continues to increase and the evaporative fluid is discharged into the ambient causing the air to cool which accelerates the ambient flow further and decreases the pressure. On the second hill formation the lower pressure causes a thrust. As the flow moves relative to the second hill formation the Mach number decreases and then increases as it descends the second region. A condensing fluid is discharged causing the water content of the air to condense releasing heat which results in a decrease in Mach number and an increase in pressure. The increased pressure on the second hill formation will produce a thrust which can be used to turn a rotor. The present invention provides an airfoil for producing work and power directly from the moisture in the air. It has no dependence on wind speed and its energy source is directly derived from the always available ambient atmosphere.

WO_2017213485_A1

Resumen de: US2019257283A1

The invention relates to wind power and allows effectively convert the kinetic energy of the wind, after its (wind) accelerating, to electrical power. The multi-stage wind turbine, which allows multiple accelerate directed air flow (wind), even of most minimal speed, up to strong wind and convert it's energy into electrical power, is proposed. It is achieved due to modularity of installation, where the wind is accelerated within each module due to the processes of capturing the initial wind flow, injection-ejection and aerodynamic Coanda effect as well, by virtual necks and conical confusors nested one into another. The system of truncated cones and virtual necks with optimum aerodynamic sizes provides the capture of the airflow not only perpendicular to the base of these cones, but also from lateral sides of these cones. Moreover, the area of wind flow capturing by lateral surface of this system, depending on the number of stages, several times exceeds the area of wind flow capturing by base of first confusor from side of wind flow. In proposed installation for increase of output power, three parameters are used at relatively small sizes of airscrew. In this case, the wind flow, which is captured by working part of the wind turbine, is compressed by all sides, increasing the speed of the directed airflow, acting on the airscrew. All turbine stages, except the last stage, represent the not full Venturi tubes consisting of a confusors and virtual necks. The last stage represen

WIND ENERGY AMPLIFIER IN THE FORM OF A ONE-SHEET HYPERBOLOID

NºPublicación: EP3527815A1 21/08/2019

Solicitante:

CALLE MADRID ALFREDO RAUL [PE]

CN_110073099_A

Resumen de: EP3527815A1

The One-Sheet Hyperboloid Wind Energy Amplifier amplifies the wind speed exerted on the wind system propeller, by increasing the pressure and speed of naturally occurring wind. It is possible to increase the speed of wind and, consequently, its force and kinetic energy, by continuously channeling a wind flow passing through a "one-sheet hyperboloid" aerodynamic structure, where the wind flow inflow surface is larger than the outflow surface for the same wind flow.Potential benefits associated with using the Wind Energy Amplifier extend to any wind system intended to harness wind kinetic energy and subsequently convert it into any other type of energy, without being limited or restricted to power generation. However, it is important to note that the greatest potential of the Wind Energy Amplifier lies in improving performance and generating capacity in respect of power produced by wind turbines (power generating windmills).By using the One-Sheet Hyperboloid Wind Energy Amplifier, wind systems in general can increase wind speed and, consequently, increase the power and performance of a wind system, given a predetermined constant or inconstant kinetic wind energy, enabling an increase in the power generated by any wind system in general.
