Designing 3kW Vertical Axis Wind Turbine Blade

Click For Summary

Discussion Overview

The discussion revolves around the design of a vertical axis wind turbine blade intended for a generator with a power output of 3kW. Participants explore concepts related to blade design, mechanical functionality, and the challenges associated with maintaining rotational inertia.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • Akmalidin Alimov proposes a blade design that concentrates wind force at a specific point to enhance rotation, particularly at the connection to the rotor, which is made heavier.
  • Some participants express skepticism about the feasibility of maintaining rotation through inertia, noting that this approach may involve complications.
  • Links to other threads and resources on blade design are shared, suggesting that there may be additional insights available from previous discussions.
  • There is a mention of the complexity and cost associated with proper blade design, indicating that it is a detailed process requiring expertise.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the effectiveness of the proposed blade design, and multiple viewpoints regarding the challenges of maintaining rotational inertia are present.

Contextual Notes

The discussion highlights the potential limitations of the proposed design, including mechanical considerations and the need for further exploration of blade design principles.

Hi,

I am designing vertical axis wind turbine for generator with 3kW power. Prior to make big blade I have designed small 3D printable version to test. I want to concentrate the force of wind into one point by making specific blade .It would make the blade rotate even after wind passes. That point which is connection section of blade to the rotor of generator and it is made heavier. I do not know from mechanical point of view if my concept works in a way that I want. Please see the modeled blade and give feedback.

Thank you,
Akmalidin Alimov

It sounds to me like you would like to create a blade design that keeps spinning with inertia which has its complications. Here is a link to another blade design thread, you might find some useful PDFs and comments on blade design there :wink:

Thank you very much!
Do you do blade designs as well? I am looking for a freelancer.

Haha I would argue I am greatly under qualified for such job :DD Blade design is quite a tedious and lengthy process to get right so expect to pay a hefty penny. I had a chance to glance through THIS book at my teachers office and it seemed really rich and well written. It might be of some better assistance.

I see. Thank you anyway !
