Airfoil Blades, by the wind. A much more effective way to catch the wind is to take advantage of aerodynamic principles, resulting in a capability for much higher rotation speed. The key aerodynamic principle to consider is the airfoil.作者: negligence 時(shí)間: 2025-3-22 04:38
Measuring Performance,on, gearbox ratio, and number of blades. This chapter presents a method and setup for quantifying power output, giving a measurement by which the efficacy of a design can be assessed. Incremental design changes can be quickly tested in a trial-and-error approach that converges to form the best solution.作者: definition 時(shí)間: 2025-3-22 09:23 作者: 錢(qián)財(cái) 時(shí)間: 2025-3-22 15:24 作者: textile 時(shí)間: 2025-3-22 20:02 作者: Indurate 時(shí)間: 2025-3-22 21:52 作者: giggle 時(shí)間: 2025-3-23 03:17

The Generator,or a wind turbine generator. This chapter involves experimenting with generators by working with a LEGO-based design, including the construction of a hand-cranked generator that uses manual motion to spin it. In later chapters, this manual rotation will be replaced by energy from wind.作者: DEAF 時(shí)間: 2025-3-23 11:26
The Gearbox,from the rotational input. This increased rotation speed makes the wind turbine produce a higher electrical output power. Gearbox design involves some complexity in choosing gears as rotation speed and torque must both be managed.

The Vertical-Axis Turbine,en in use are horizontal axis, as that style is more efficient than vertical axis turbines. This difference in efficiency is largely a matter of aerodynamics—horizontal-axis turbines’ blades take full advantage of aerodynamic lift.

The Horizontal-Axis Turbine, power than a vertical-axis design does because the blades catch a much larger area of wind. This area of capture is called the . and is defined by the diameter encircled by the airfoil blades as they spin. For comparison, the swept area of the vertical-axis turbine is the diameter of one cup of the作者: 圖畫(huà)文字 時(shí)間: 2025-3-24 04:27 作者: VAN 時(shí)間: 2025-3-24 10:01 作者: 跳脫衣舞的人 時(shí)間: 2025-3-24 14:02 作者: Hyperalgesia 時(shí)間: 2025-3-24 16:29
