Introduction
General parts or a wind turbine:
TowerRotorNacelle
Awind turbine is a device that converts kinetic energy from the wind intomechanical energy. If the mechanical energy is used to produce electricity,the device may be called awind generator

Introduction
Big wind turbines
Mwatts order
Actual generation : 1-2 Mw
Next Generation: 5Mw
In order to produce energy as an industry
Flying wind turbines will have this use
because of the big amount of energy in
high altitude.

Energy in the windIntroduction
There are 3 factors: Air density:
Relation between density, mass and kinetic energy
Rotor area:
Relation between rotor area, and rotor diameter
Wind speed
This is going to make us choose the kind of wind turbine

Betzs law
Wind Atlas Mathematical calculations
Theory
It represent Speed, Frequency andthe relation between them.
How to measure when the
turbine is moving all the time?
How to control de direction ofthe flying wind turbine?
How flat is the surface:The flatter the better

Betzs law
Wind Atlas Mathematical calculations
Theory
Good measurement in the position withthe rotor will be, will give us a good ideaon the quantity of energy that we canobtain.
The measurements for Flying windturbines are for huge areas.

Mathematical calculationsTheory
Weibull Distribution:In probability theory and statistics, theWeibull
distribution is a continuous probability distribution.Important: Probability
Define wind variation)(this is important because of thedesign and cost)
what is the value of the area under the line?
Same problem: difficult tomeasure

Advantage:Its not a new technology,it is used especially for
offshore wind farms
Disadvantage:Flying wind turbines are
moving continuously,that means hugedifficulties for themaintenance team.

CONCLUSION
Advantages PresentedAt higher altitudes, wind has more power and velocity and is moreconsistently predictable. As power generated goes up because of higher
wind resistance proportional to the cube of relative velocity, morepower can be generated. That works out to be some 8 27 times the
power produced at ground level. The tethers can haul in thekites/balloons housing the turbines during storms or for generalmaintenance work. Less pollution is an advantage, as well as the factthat it will not take up much precious ground space for installation.
Not in every document found this idea go in the same way, some of thewriters have the opposite point of view.
Small improvements mean benefits
