how helicopter flies?

Answer 1

The helicopter blades act like a giant propellor and generate thrust. By tilting the helicopter slightly forward, some of the thrust holds it up and some of the thrust pushes it forward.

The little propellor at the tail of the helicopter keeps the helicopter going straight. If the helicopter didn't have that small side thrust at its tail, then it would try to spin around like a frisbee.

Answer 2

The rotation of the blades creates a low pressure area above the blades and a high pressure area below them. This causes the helicopter to raise. Same principal as an airplane wing.

Answer 3

the spinning of the rotors creates torque in the form of air being forced down on the ground which makes the helicopter rise. when the helicopter tilts slightly forward the air pushes back causing it to move forward. the rotor on the back is just to stablize the helicopter and keep it from spinning and ultimately crashing.

Answer 4

An airplane flies when air flowing over the wings creates lift. The rotors of a helicopter are the wings. When they rotate and air flows over them, they create lift.

Answer 5

One thing I DO know: the tail propeller on its side stops it from spinning... It still CAN spin, but it's controllable by slowing or speeding up that propeller...

Answer 6

The thingy goes around.
