- Helicopter - Wikipedia
A helicopter is a type of rotorcraft in which lift and thrust are supplied by horizontally spinning rotors This allows the helicopter to take off and land vertically, to hover, and to fly forward, backward and laterally
- Helicopter | Facts, History, Types | Britannica
A helicopter is an aircraft with one or more power-driven horizontal propellers or rotors that enable it to take off and land vertically, to move in any direction, or to remain stationary in the air
- How does a helicopter work? - Explain that Stuff
The science of a helicopter is exactly the same as the science of an airplane: it works by generating lift—an upward-pushing force that overcomes its weight and sweeps it into the air Planes make lift with airfoils (wings that have a curved cross-section)
