Helicopters don't just have 3 blades. It depends on the size and Weightlifting capability. Small helicopters such as a Robinson R22 have only 2 blades, the military Merlin has 5 and the Chinook has two rotors with usually 3 blades each.

Why do wind mills have only three blades?
Having three blades is a common design choice for wind turbines because it provides a good balance between efficiency and cost. Three blades are able to capture a sufficient amount of wind energy to generate power while keeping the overall cost of the turbine lower compared to having more blades. Additionally, three blades create a more stable and quieter operation compared to turbines with other numbers of blades.
Do windmills have three or four blades?
Four
What is the difference between fans with 3 and 4 blades?
nothing a fan with three blades is just weaker and smaller than a fan with four blades! <3
What is the ideal number of blades on the wind turbines?
Three
Why are wind turbines three bladed when more blades should catch more wind?
the reason there is only three blades is because four blades would add weight and wind resistance, in some countries they use two or four bladed turbines though. \
What size blade is on a 325 John Deere?
The regular deck on a 325 is 48" with three blades (You can only buy blades in sets of three from John Deere.) The standard blade is 16.6 inches in length.
How many blades on a wind generator produce the fastest speed?
Wind generators with fewer blades typically produce faster speeds as they have less drag and are more efficient at capturing wind energy. However, the exact number of blades that produce the fastest speed can vary depending on the specific design and conditions of the wind turbine. Generally, turbines with either two or three blades are commonly used for their balance of speed and efficiency.
Why does windmill have only 3 blades?
Windmills typically have three blades because it strikes a balance between efficiency and cost. Three blades have been found to be the most efficient design for capturing wind energy while minimizing material and construction expenses. Additionally, a three-blade configuration allows the windmill to operate smoothly and withstand varying wind conditions.
Why do fans have 3 wings?
An electrical fan can have two, three or four blades. The main thing is that the number of blades must be balanced to avoid juddering.
How many number of blades are there on a wind turbine or windmill?
Most modern wind turbines have three blades. This configuration has been found to be the most efficient for capturing wind energy while minimizing noise and vibration. Some smaller turbines may have fewer blades for specific applications.
How often do you sharpen your mower blades?
Probably every two to three years.
