How Can a Helicopter Go Straight up?

How Can a Helicopter Go Straight up?

Helicopters can go straight up or down and hover in the air without moving. They can also fly backwards and sideways. They can even take off or land without a runway!

Instead of regular wings, Helicopters have three or more wing like blades which spin above the helicopter’s body. These are called rotor blades. The rotor blades spin so rapidly that they produce elevation and, in effect, screw upward, lifting the helicopter into the air.

The secret to moving forward (and backward and sideways) is that the rotor assembly can be slightly tilted. When it is tilted forward, the rotor blades pull the helicopter forward. Some helicopters have little tail rotors which enable them to turn right or left. These capabilities make helicopters ideal for many tasks.

Flying helicopters is a lot harder than flying airplanes. Did you realize you need both hands and both feet to fly a helicopter successfully?
