The size of a helicopter blade affects the speed of rotation by determining the amount of lift generated and the amount of drag produced. Larger blades tend to generate more lift but also experience more drag, which can impact the speed of rotation. Adjusting the blade size can help optimize the balance between lift and drag to achieve the desired speed of rotation.

Does adding mass to a paper helicopter affect the rotation speed of the helicopter?
If you are adding mass to the outside of the blades, it will make the blades rotate much more slowly. However if you add mass to the inside of the blades it will increase the rotational speed, however more force will be needed to start the rotation.
How does the helicopter blade works at when takeoff?
During takeoff, the helicopter blade applies lift by generating upward airflow which creates a pressure difference between the top and bottom of the blade. This pressure difference causes the blade to move upward, lifting the helicopter off the ground. The angle of attack and rotation speed of the blades also play a significant role in generating lift for takeoff.
Do helicopter blades break the sound barrier?
No, helicopter blades do not break the sound barrier. The tips of the blades can approach the speed of sound, but the entire blade does not exceed the speed of sound.
Why a helicopter falling during auto-rotation could reach a terminal speed?
During auto-rotation, a helicopter's main rotor generates lift from the relative wind passing over the blades as the helicopter descends. If the helicopter dives too steeply during auto-rotation, the increased airspeed can cause the rotor blades to stall, reducing lift and potentially allowing the helicopter to reach terminal velocity. At terminal velocity, the forces of gravity and air resistance are balanced, leading to a constant descent speed.
Why a helicopter during autorotation could reach terminal speed with out the pilot changing the controls?
Three forces work here. There is gravity, air resistance and the lift force made by the blades autorotation. When the air resistance and gravity forces are equal in strength, this means that the helicopter has reached its terminal velocity. It cannot fall any faster than it is. As the helicopter is using auto-rotation, the pilot does not need to change any controls because the forces will balance out themselves. The helicopter, with the aid of the still spinning blades of the helicopter, will be able to make a safe landing.

How fast would a helicopter blade need to be to catch the air on fire?
Since air is not inherently flammable, there is no speed at which a helicopter blade would catch the air on fire.
What increases the thrust of an helicopter?
The 'angle of incidence ' of the rotor blades and blade speed.
What is the phenomenon called that limits a helicopter's maximum speed?
Retreating blade stall.
In a wind turbine - does increasing the blade length or decreasing the blade length increases the speed of the turbine?
Decreasing the blade length will increase the rotation speed, and thus the turbine speed ( for constant wind speed ).
How fast will the helicopters go in the future?
Not much faster. True helicopters are limited in airspeed. The helicopter blade can not fly faster than the speed of sound or it begins to flutter and even stall. The advancing blade has to go through the air faster than the retreating blade. The speed of the blade is the sum of the speed of the helicopter in forward flight plus(+) the rotational speed of the turning blades. If they can design a blade that will work at slow speeds and at speeds greater than Mach 1, then maybe they can build a faster helicopter.
Do helicopter blades break the sound barrier?
No, helicopter blades do not break the sound barrier. The tips of the blades can approach the speed of sound, but the entire blade does not exceed the speed of sound.
How does earth's varying orbital speed affect it's rotation?
The earth's orbital speed has no influence or effect on its rotation.
Why a helicopter falling during auto-rotation could reach a terminal speed?

At terminal velocity, the forces of gravity and air resistance are balanced, leading to a constant descent speed.
Why do helicopters fly so slow?
What is the limiting factor for helicopter speed you ask? What happens to the rotor as the velocity of the helicopter increases? The relative speed of the tips of the rotors changes because of the wind speed. On the advancing side of the rotor the speed increases by the speed of the helicopter. On the retreating side of the rotor the speed decreases by the speed of the rotor. One of two things happens as the helicopter reaches a high speed: A: If it is a large rotor, the advancing blade will reach the sound barrier and sap energy from the rotor, slowing it. Significant damage may occur to the helicopter. B: If it is a smaller rotor, the retreating blade will slow to the point where stall occurs, and the helicopter will be forced into a turn while losing altitude and decreasing speed, then it will usually recover if altitude permits. Option B can be mitigated by increasing rotor RPM at higher speeds. In this case the rotor speed becomes the limiting factor, as the centrifugal forces at the root of the blade are quite incredible.

Why a helicopter falling during auto-rotation could reach a terminal speed without the pilot changing any controls?
The helicopter begins to fall because gravity is pulling its weight. As the helicopter accelerates, the air passing past the helicopter creates drag, as the helicopter continues to accelerate the drag Increases until the drag becomes equal to the weight, stopping it from accelerating. Even if the helicopter did not auto rotate it would still reach a terminal speed, however the terminal speed for the non auto rotating helicopter would be a lot higher and the helicopter would take longer to reach this speed.
