The yacht achieved a dead downwind speed of about 2.8 times the speed of the wind. [1] [18] On June 16, 2012, Blackbird set the world's first certified record for going directly upwind, without tacking, using only power from the wind. The yacht achieved a dead upwind speed of about 2.1 times the speed of the wind. [1]
The rotor-powered InVentus Ventomobile racing at the Aeolus Race 2008 Small wind turbine power output. Rotor-powered vehicles are wind-powered vehicles that use rotors—instead of sails—which may have a shroud around them or constitute an unducted propeller, and which may adjust orientation to face the apparent wind. The rotor may be ...
This list also includes the most powerful onshore wind turbines, although they are relatively small compared to the largest offshore ones. As of June 2024, the most powerful wind turbine in operation is the world's first 18MW semi-direct drive offshore wind turbine, developed by Dongfang Electric Corporation. [1] In October 2024, Dongfang ...
Software helps design wind turbines. There are several aero-elastic packages that are used in this design process. FOCUS6 aids in the design of wind turbines and turbine components such as rotor blades. It was developed by Knowledge Centre Wind turbine Materials and Constructions (WMC) [1] and Energy Research Centre of the Netherlands (ECN). [2]
Wind-turbine blades in laydown yard awaiting installation. The primary application of wind turbines is to generate energy using the wind. Hence, the aerodynamics is a very important aspect of wind turbines. Like most machines, wind turbines come in many different types, all of them based on different energy extraction concepts.
The rotor diameter varies amongst particular versions of turbines. The diameter for version C89 is 89 meters, 93 meters for version C93, 96 meters for version C96, and 99 meters for C99. Blade lengths are 43.2 m for C89, 45.2 m for C93, 46.7 m for C96 and 48.2 m for C100. Liberty Wind Turbines use 4 generators that have permanent magnets.
An airborne wind turbine is a design concept for a wind turbine with a rotor supported in the air without a tower, [1] thus benefiting from the higher velocity and persistence of wind at high altitudes, while avoiding the expense of tower construction, [2] or the need for slip rings or yaw mechanism. An electrical generator may be on the ground ...
