Why do helicopters always have a set of two blades?
Helicopters have 2 sets of blades to keep the helicopter balanced. This is due to the unique shape of the helicopter.
How many blades does fastest helicopter have?
Helicopters created nowadays generally have 2 or 3 blades. The fastest recorded helicopter has 3 blades. as it revolves more pressure is put forth and therefore the helicopter travels faster
How many rotors does the helicopter have?
Helicopter can have 2 blade, 4 Blade, 6 Blade, 8 Blades. Selection of this Blades depends up on the Power Rating. For a small 2 Ton H/C, it can have 2 Blades. 5 Ton H/C can have 4 Blades etc..
How does the helicopter stay stationary in the air?
Two things keep a helicopter flying, and another keeps it flying straight. To take off: 1) The blades are shaped like the wings of an airplane and create a difference in pressure (high underneath the wing, low above). This difference in pressure "pushes" the helicopter upwards (lift). But because of gravity, however, there might not be enough lift to take off from the ground. 2) In order to take off, the blades must rotate at supersonic speeds (to be stronger than gravity's push downwards), this make it possible to gain altitude. To "Fly:" 1) A helicopter's blades in air act like a boat's propeller in water. If the blades rotate at an angle, it will start moving. To make the helicopter hover, the blades must be perfectly straight up. At the same time, the rotating blades make the helicopter itself rotate the other way (about the axis of rotation). In a GPS, the helicopter would not be going anywhere like this (with no angle on the blades), but the Direction at which it is looking will be changing in circles 2) Helicopters need a way to fix this crazy-out-of-control spinning. They can use a tail rotor for this, but they can also use a "twin" set of blades that rotate in opposite directions (counter-rotating blades). With the addition of counter-spinning blades, now the GPS will be pointing at 1 direction. in summary: 1) By keeping the blades rotating fast enough to be lifting with the same force as gravity is pushing down, the altitude is kept the same. 2) By keeping the Blades from spinning at an angle, the Helicopter does not move to the sides. 3) By using a counter-rotating blades set, the helicopter is able to keep looking at one direction. with these 3 things, Helicopter are able to hover in air, and their GPS can be kept and a fixed height, at fixed position on a map, and at a fixed direction.
Why does some Russian military choppers carry 2 blades?
Blades on a helicopter provide both lift and thrust, therefore, the more blades, the more lift and speed can be obtained. IT should also be noted that more horsepower is needed for the additional blades so it can be a trade off in fuel consumption.
Can oswald fly in epic mickey 2?
Yes, trailers of the game show Oswald flying using his ears like helicopter blades.
Why a helicopter chopper?
Q: Why is a helicopter called a "Chopper"? A: I think the names comes from the sound of the blades make: whop-whop or chop-chop. FYI, the helicopters that have the loud popping of the blades are usually a 2-blade of the Bell Helicopter design. The multi-blade helicopters do not have a sound as distinctive as the Bell helicopters. The sound comes from the blade striking the vortex generated by the blade ahead of it.

How helicopter flies?
First you need to understand lift and how it is generated. If you do a google image search for "airfoil" you can see what it looks like. The top has a curve to it and the bottem is flat. As the airfoil passes through the air, lets say at a speed of 1, the air going over the top of the airfoil must travel at a higher rate of speed, maybe 1.5, that the air giong under the flat bottem. This is known as Bernoulli's Principle or lift. Now, if you take 2 or more long thin airfoils or blades and attach them to a center mast and provide a means for them to tilt and twist you have a basic rotor head of a helicopter. As the blades are spun through the air they create lift, much like if you have your hand out the car window. If you incrase the pitch of the blades by twisting them so the front edge goes up you get more lift and the helicopter goes up. If you tilt the blades to the left, fore example the helicopter will go left. Everything has an equal and opposite reaction. In this case if you turn the rotor blades to the left or counter clockwise the body of the helicopter (fusealage) will want to turn to the right. This is where the tail rotor comes into play. It pushes air to the left to keep the fusealage from turning. If you want to turn the helicopter to the left then you would incrase the pitch of the tail rotor blades to over come the twisting force of the helicopter. To turn to the right you would reduce the pitch of the tail rotor blades and let the helicopter twist agians the main rotor.
