  • Members of the Everett Wind Energy Team (EWET) discuss the design, construction, and testing results of their vertical axis variable pitch wind turbine. WSU mechanical engineering student Kaleb Willis explains turbine design. EvCC electrical engineering student Sam Ayars discusses the electrical components of the turbine.Sarah Hastings, recent WSU graduate in mechanical engineering, talks about the diagnostic process.
    The turbine was designed as the team's entry in the 2021 Collegiate Wind Competition. EWET is a collaboration of students of Washington State University Everett and Everett Community College.

    Excellent. Just a thought for an addition to reduce rotational drag is to add light, aerodynamic plastic(?) coverings to the arms without impacting functioning. Great work to all of you.

    Hi I really enjoyed this video! My team and I are trying to build a VAWT for our final mechanical engineering project. We were wondering how the main shaft that rotates with the blades is attached to the rest of the system? A response would be much appreciated thank you

    you could have done it completely mechanical, the wind vane would be a rudder and it would rotate the eccentric disc accordingly but its a good idea in general.

    I think that this is a great piece of job. Correct me if I'm wrong, when you use speed multiplying gears, you need more torque, right? But from only three blades i don't think it's enough, actually. What about using 6 - 7 blades? Could this work to increase the exposure to the wind and so give more torque? Thanks! Cheers!

      exactly, they need more area to increase the torque, more blades or larger ones

    Does your unit provide pitch which is positive and negative ? you will need it

    Each addition, each gear, represents an approximate loss in efficiency of ten per cent. Ideas for masking or feathering vanes on the retreating side continue to come up over the years. The system for feathering has to work against air friction on the far side, work which is subtracted from the total available. Unless the gain in improved utilization of the wind covers or more than covers the total in losses, the additions cannot be justified. Real figures are required

    Good Concept it needs just some adjustments. I wonder if the SolidWorks design is free to access?

    I appreciate that you want your design as compact as possible but I would nevertheless suggest that you increase the diameter of your rotor so that you up the torque it generates. Personally I prefer VAT's because of all the advantages they present, particularly two points, (1) Being able to place them closer together with the space efficiency that results from that and it's ramifications. (2) They are more friendly to wildlife particularly birds. (3) Because they are small, they lend themselves better to domestic use and should be able to provide an higher output that a similarly sized HAT.
    All the best with your project.

      Pieter, Thank you for your comment. The turbine was made for the Collegiate Wind Competition, which dictates that the rotor be 45 cm. The reason for this is that in the competition, the turbines from the various teams are tested in an NREL wind tunnel, built specifically for the contest.

    you are a perfect example of over engineering the mechanical solution to a problem...... even if you get it to work in the disipline in which you have started. The cost of research and development and added manufacturing costs have to be implemented into retail sales making it a super expensive solution..... but I suppose this is what modern academia preaches to its clientel... over paying youths . . . didn't you ever see good will hunting?

    Silly boys! I've built VAWTs for over 50 years. I found out early on, USEABLE power from average (12-knott) wind, was possible by using my turbines to compress air.
    I then use that stored compressed air against either pistons or through a tangential-flow turbine (Pelton wheel) to create any voltage / amperage I want, safely, down on the ground in my shop.

      the pitch regulation you have made is very excellent,and i am major in CFRP blades, in fact ,it is easy to make a CFRP blades,we do not need complex laboratory,just epoxy and carbonfibre, i am very expected for next year and your CFRP VAWT!

    Respect and admiration for the video, period. However if you would only stop for a moment to make some basic math calculation you will find out that way before building the prototype. You may not even need to do the math, just looks other prototypes that already exist and find out how much power they output and why, and you will save yourself a lot of time and headache and more likely you would have build a prototype with all those considerations. There is so many wrong things with your prototype and your analysis that is hard to start commenting or suggesting. I just would recommend you to research and document yourself and learn some math and basic physic in order to have a more productive journey. Every one is welcome to play the engineering game, but knowing some math and building an knowledge as foundation will help you go far.

    Two items, you have to add more blades, Helix design blades are more efficient.
    Aerodynamically you have to add end caps to increase the efficiency by 4%.
    The biggest problem with verticals is the generator being too large for blade size.

    Check out Peter Sharps patent on his cycloturbine. Blade pitch is passively controlled , no power needed to change pitch. It is awesome. Patent 4334823
