Advantages of two-blade wind turbines compared to three-blade wind turbines

With 2 blades, installation and transport costs are lower than those with 3 blades. In addition, the tip speed ratio of the 2 blades is higher than that of the 3 blades. If it is used to generate electricity, the gearbox speed increase ratio is lower than that of 3 blades, so the cost. of the gearbox is less.

ps

The hub structure of the 2-blade is special, with a rocker structure, and the fatigue problem is more serious than that of the 3-blade. Each therefore has its advantages and disadvantages.

What will happen if a wind turbine blade falls?

In this accident, the wind turbine blades were placed on a truck due to the force of the wind. The blades are too long and the volume far exceeds the body. Due to the structure of the truck, the tail of the wind turbine blades hangs very low and the rear truck can easily touch the blades.

According to online media, a serious traffic accident occurred at a traffic light intersection in Bucheng County, Shaoyang City, Hunan Province. It turned out that a van hit an A. The truck was carrying wind blades, and the wind blades were directly inserted inside the van, causing a serious traffic accident that killed a person and injured one.

According to information collected, the truck carrying wind turbine blades stopped at a traffic light intersection.

Since the wind blades are so huge, even if a large truck is used to transport them, the size of the wind blades far exceeds the vehicle body.

At that time, a van was coming from the opposite direction. When the van on the opposite side turned left and entered the intersection, for some unknown reason, it suddenly hit thisyou huge blade of wind. force of the wind The blades passed directly through the window of the minivan, directly causing the tragedy of one death and one injury.

Some netizens claimed that the van hit the wind blades. It may be that when the van was turning left at the intersection, it was in a blind spot and did not see the blades before hitting it.

Of course, some netizens think it's because the truck lowered the tail of the wind blade too low. If the tail of the wind blade does not go very low, then it is impossible for the van to do so. turn around. Contact with wind blades.

Of course, there is currently no confirmed explanation as to why the van hit the wind blades. Additionally, there were no reports of anyone breaking any traffic laws during this incident. It should therefore not be ane case of traffic violation.

But we must also take this as a warning. We must pay attention to road conditions when we set off, and for the sake of our own safety, we must also obey the traffic laws.

If a wind turbine blade falls, it will affect the safe operation of the unit. As a key part of a wind turbine, the quality of the blades directly affects the operating efficiency of the unit. Because the blades are exposed to the air year-round and are eroded by wind loads and the environment, they are easily damaged. damage continues to develop under the action of alternating loads. Eventually, the blades break, affecting the unit's safe operation. When one of the blades breaks, it will cause an impact on the other blades.
