The concept of the number of wind turbine blades - the strength of the wind turbine. The ratio between the total surface area of the wind turbine blades (projected in the direction of the wind) and the surface area where the wind passes through the rotor (swept rotor surface) is called solidity (or solidity ratio, volume ratio), and constitutes a reference data for wind turbines. ?
These are several types of horizontal axis wind turbines, with schematic diagrams showing four types of wind turbines: single blade, double blade, three blade and multi blade. The method of calculating solidity. of the wind turbine is as follows: S is each the projected surface of the blades in the direction of the wind, R is the radius of the wind wheel, B is the number of blades and σ is the realism ratio. σ=BS/πR2.
A wind turbine is an electrical device that converts wind energy into mechanical work, which causes the rotor to rotate and ultimately produces alternating current. In one wayIn general era, wind energy is also solar energy, so we can also say that a wind turbine is a thermal energy generator that uses the sun as the heat source and the atmosphere as the working fluid.
Help! ! Someone who understands wind turbines can help me with the answer~
Yes, the cabin can rotate and is always facing the wind. The professional term is lace. Of course, the pod will not always rotate in one direction, such as clockwise or counterclockwise. If the wind direction is unlucky, it will always move in the same direction. The fan will rotate at most seven to eight hundred degrees. must also rotate actively, which is called undocking. Prevent the cables inside from being pulled out.
A wind turbine is an electrical device that converts wind energy into mechanical work, which drives the rotationation of the rotor and finally produces alternating current. Wind turbines generally consist of components such as a wind wheel, a generator (including devices), a steering (tail), a tower, a speed-limiting safety mechanism, and an energy storage device.
Detailed information:
The principle of wind power generation is to use wind energy to rotate the blades of the windmill, and then use a multiplier of speed to increase the rotation speed to encourage the generator to produce electricity. According to current wind turbine technology, electricity production can start at a breeze speed of around three meters per second (the breeze level). Wind energy is becoming a craze around the world because it poses no fuel problems and produces no rair pollution.
Generally speaking, a wind turbine is a thermal energy engine that uses the sun as a heat source and the atmosphere as the working fluid. Wind energy uses natural energy. This is much better than diesel power generation. But if used in an emergency, it is still not as efficient as a diesel generator. Wind power is not considered a backup energy source, but it can be used long term.

The front of an electric locomotive is so large that it has great wind resistance. Why not install a wind turbine out front. car to produce electricity and recover energy?
There are many models of wind turbines. From the point of view of structure, they can be divided into those with reducers and those without reducers. It can be divided into fixed pitchand variable pitch, and the stepping method can be divided into hydraulic stepping and electric stepping. In total, there are no less than four or five types. Do you want to design it?
If the mechanism is different, the hub size will be very different. There are several lightning protection systems for wind turbines. The weather mount on top of the machine gun is equipped with lightning rods. are connected to the ground grid by wires. There are metal blocks at the ends of the blades, leading to a ground grid from inside the blade, a lightning protection carbon brush between the wheel hub and the nacelle, and between the nacelle and the nacelle . turn, which reduces contact resistance and improves conductive efficiency. The tower and the tower connection flange are also connected via a flexible wire. There are also lightning protection modules, surge protectors, etc. in the electrical circuit,which can protect and cause lightning. There are many books on this topic, most of them are published by China Electric Power Publishing House. There is a specialty store in Beijing. If I have the CAD drawings, I won't tell you.

Wait~~
Wind coming from the front of the vehicle It is divided into two types:
One is the wind generated by its own kinetic energy (relative wind). Where does this energy come from? It transforms itself into electricity. Do you want to reconv ituse electricity? Isn't it a waste of energy to move around like this?
The second is natural wind from outside, which can be divided into three types: 1. Wind from behind 2. Wind from side 3. Wind from front;
1 can be used; 2 can also be used; 3 can be used, but the available power is estimated to be not very high. Think about how much power such a large wind turbine on the front of the car can generate?
The most important thing is that the first wind is the main wind of the vehicle. The second wind can be almost ignored and serves no purpose.
So, in order not to mess around and waste energy, in reality no one will install a wind turbine on the car.
