An example of a wind turbine, this 3 bladed turbine is the classic design of modern wind turbines Wind turbine components : 1-Foundation, 2-Connection to the electric grid, 3-Tower, 4-Access ladder, 5-Wind orientation control (Yaw control), 6-Nacelle, 7-Generator, 8-Anemometer, 9-Electric or Mechanical Brake, 10-Gearbox, 11-Rotor blade, 12-Blade pitch control, 13-Rotor hub
The same design is used on all four sides and transmits wind and gravity loads to the four support stilts. There is also a fifth support column in the center. In July 1978, a possible structural flaw was discovered in Citicorp Center , a skyscraper that had recently been completed in New York City .
A windpost is a structural item used in the design and construction of masonry walls to increase lateral wall stability and protect them against damage from horizontal forces imposed by wind pressure, crowd or handrail loads. [1]
A vertical wind tunnel (VWT) is a wind tunnel that moves air up in a vertical column. Unlike standard wind tunnels, which have test sections that are oriented horizontally, as experienced in level flight , a vertical orientation enables gravity to be countered by drag instead of lift , as experienced in an aircraft spin or by a skydiver at ...
For example, the wind tunnel at Peenemünde was a novel wind tunnel design that allowed for high-speed airflow research, but brought several design challenges regarding constructing a high-speed wind tunnel at scale. However, it successfully used some large natural caves which were increased in size by excavation and then sealed to store large ...
These columns had capitals of a design now sometimes known as "Tower of the Winds Corinthian", a "late variant form" lacking the volutes ordinarily found in Corinthian capitals. [12] The capital on the roof, which supported the Triton weather-vane, used the same form; the broken lower part of this remains in place.
IEC 61400 is a set of design requirements made to ensure that wind turbines are appropriately engineered against damage from hazards within the planned lifetime. The standard concerns most aspects of the turbine life from site conditions before construction, to turbine components being tested, [ 1 ] assembled and operated.
A diagram of a panemone whose wind-catching panels are arranged to turn edge-on to the wind when moving against the wind's thrust, and side-on when moving downwind to harness the wind's motion. A panemone windmill is a type of vertical-axis wind turbine. It has a rotating axis positioned vertically, while the wind-catching blades move parallel ...
