FOR THE WIN(D)
We are a team of four senior engineering students at Loyola University Maryland who are working this year to design a vertical axis wind turbine that is commercially cost effective for a home in an urban environment, specifically the Baltimore area.DESIGN SOLUTIONS
The dc motor will be used to keep the turbine spinning even in times of low wind. Our intended design is to have the motor disengage from the turbine when the wind gets the turbine spinning fast enough (less than 3mph winds are all that is needed to allow the turbine to rotate under its own power). To accomplish this, a microcontroller will beDESIGN ALTERNATIVES
The vertical axis wind turbine (VAWT) has its own unique set of pros and cons too. VAWTs produce less power, but because of their design, they are also placed much lower to the ground. One of the intrinsic benefits of the VAWT is that because the entire shaft rotates, the motors can be located on the ground at the base of the turbine makingfor
DATA ANALYSIS
The coefficient of power is the ratio of the actual power that the turbine produces to the ideal power that can be obtained by the wind turbine. The following equation was used: Where ρ is the air density, A is the swept area of the blades, and vo is the speed of the wind. The tip speed ratio was calculated using the following equation:MEET THE TEAM
As a young Albanian boy, Krisildi wanted nothing more than to be a weather man. He failed at that. After being kicked out of the Academy for Weather, Firefighting, Ukulele, and Law (he failed his firefighting term project and let the school burn down) he decided to enact his revenge on society for letting him down: he would learn to harness the power of the weather and use its force to perform RESULTS - FOR THE WIN(D) Taking the measured results of Hz, speed of the blades (mph), and voltage output (VDC) required some conversions before analysis. Table 2 shows an example of results taken. BACKGROUND - FOR THE WIN(D) Design Alternatives The Darrieus Self-Starting Problem THE DARRIEUS SELF-STARTING PROBLEM The reason the Darrieus is incapable of self starting is because there is an initial rotation velocity of the blades required to create the angle of attack. There are existing methods of correcting this problem like: Darrieus/Savonius hybrid, guide vanes, and folding airfoils. The Hybrid Darrieus/ Savonius allow a smaller Savonius blade profile ENVIRONMENTAL CONCERNS A concern with any form of wind turbine is how it will affect the wildlife, like birds, with which the turbine will share air space.

In order to do this we need to take into account all our costs to build and test our prototype next semester.SAFETY CONCERNS

The first limitation is the Betz Limit. The Betz Limit applies to all wind turbines, whether they are horizontal axis wind turbines or vertical axis wind turbines.

SOCIETAL RELEVANCE
With a decreasing reserve of nonrenewable resources like natural gas and oil and rising utility rates, “going green” is extremely relevant to our current society.For the Win(d)
