Are the mass collapse of "typhoon-resistant" wind turbines caused by low-price bidding?

If small circles 5 feet in diameter were to be cut out in a pattern all along the vertical column or pillar that holds up the wind turbine. These small circles cutouts would allow for the high speed typhoon category winds to pass through the wind turbine thereby decreasing the amount of stress on the superstructure. Cutting small circles or holes in a pattern along the vertical column or pillar of a wind turbine is a concept known as "perforation" or "porosity." This design approach can help reduce the stress on the turbine structure during extreme winds, including typhoons. By allowing high-speed winds to pass through the turbine column, the perforations can: 1. *Reduce wind loads*: By providing a pathway for the wind to pass through, the perforations can decrease the pressure difference between the windward and leeward sides of the turbine. This reduction in pressure difference can lead to lower wind loads on the structure. 2. *Decrease turbulence*: The perforations can help to break up the turbulent flow around the turbine, reducing the intensity of the turbulence and the associated loads on the structure. 3. *Improve stability*: By reducing the wind loads and turbulence, the perforations can help to improve the stability of the turbine during extreme winds. However, it's essential to note that the design and implementation of perforations on a wind turbine column require careful consideration of several factors, including: 1. *Structural integrity*: The perforations must not compromise the structural integrity of the turbine column. 2. *Aerodynamic performance*: The perforations should not significantly impact the aerodynamic performance of the turbine. 3. *Maintenance and repair*: The perforations should not create maintenance or repair challenges. 4. *Cost and feasibility*: The addition of perforations should be cost-effective and feasible to implement. Cutting 5-foot diameter circles in a pattern along the vertical column could be an effective way to reduce stress on the superstructure during high-speed typhoon winds. However, it's crucial to conduct thorough engineering analyses and simulations to ensure that the perforations do not compromise the structural integrity or aerodynamic performance of the turbine.
