Mechanical question: How to adjust the axial and radial bearing capacity of the vertical axis wind t

Can I ask if the poster specialized in mechanics or wind energy?

If it is the latter:

There is no theoretical relationship between the radial force and the axial force. The radial force is calculated from the thrust moment generated by the wind acting on the entire wind. turbine. , if you have the resistance coefficient of the wind turbine, know the incoming wind speed and the wind receiving area, you can approximately calculate the wind moment, and the resistance coefficient can be calculated in the wind tunnel through the model .

The fan only weighs 300N...

If you want to ask questions, then the conditions are probably not all given.

The strong wind speed at a certain location is 20 m/s, the air density is p=1.3 kg/m3 and the effective wind receiving area is a wind turbine is S=20 m2. For example,

add The reason for the indie engine roompendant for the pressurized air fan is to ensure that the pressurized air fan is not damaged by wind, rain, foreign objects, etc., and can work reliably in the event of fire. Where it is necessary to install a pressurized air ventilator on the upper part of the building due to conditions, measures should be taken to prevent smoke from escaping from the air inlet of the ventilator. air under pressure.

Give you a rough calculation method: fan power = 1/2*Cp^P*S*v^3. Among them, Cp is the utilization rate of wind energy. the current fan is 0.35 ~ Between 0.4, then the fan power = 0.5*0.4*1.3*20*12*12*12=898.56W. The fan power is always lost. If your energy production efficiency is 80%, then it is 898.56. *80%. First of all, it should be noted that once the wind turbine exceeds the rated speedwind (generally 7 to 8 meters per second), certain measures will be taken to stabilize the generator power. So this does not mean that the higher the wind speed, the higher the power of the generator.
