Because the airplane must have airflow over it's wings to get lift. Helicp[ters get lift from the main rotor turning
the difference between an helicopter creating lift and an airplane creating lift is simple. an airplane creates lift by moving forward and its wing that has an aerofoil shaped will create lift. this gives the lift for the airplane and to fly. for helicopters, instead of the aerofoil is fix like an airplane, the aerofoil wing is rotating and create lift. that is why the helicopter does not need to move forward to gain momentum to create lift. by rotating the aerofoil (the blade) the helicopter can creates enough lift to lift up the helicopter.and that's how it fly..
It flies Like an Airplane and Hovers Like a Helicopter... or if the engine has enough power to it, and the pilot brings it up to a 90 degree climb, lets it slow down, then adjusts the throttle to hover the plane...
just like an airplane
The Harrier, informally referred to as the Jump Jet
Some people say that flying an airplane would be like riding a bike and flying a helicopter is like riding a unicycle in comparison.
A helicopter uses Benoullis principle in the exact same way as an airplane does. A helicopter has a wing just like an airplane's wing. The major difference being that instead of pushing the wing forward through the air, a helicopter swings the wings around above its head.
If the center of gravity is too far forward, the airplane may become difficult to control, with a tendency to pitch down uncontrollably. This can lead to instability and potential loss of control in flight. Pilots must ensure that the center of gravity remains within the specified limits for safe operation.
there is no way to fly without a machine like a airplane or a helicopter even a jetpack
A helicopter is a flying vehicle that uses rotors on the top of it. It is able to fly by simply taking off vertically, instead of having to traffic through a runway, like an airplane.
a bee moves by flapping its dead wing fast to fly which acts like a helicopter!
A VTOL (Vertical Take Off and Landing) aircraft is one that can takeoff and land like a helicopter, but fly like a plane. A good example is the V-22 Osprey.
To fly, helicopters have a Propeller. Airplanes have an engine that provides thrust to push it through the air, which forces air over the wings and create lift that allows the plane to climb. Helicopters have a main propellor blades that turn about a vertical axis. This large rotor provides the Lift and forward motion to the helicopter. It also has a smaller rotor at the tail that counter acts the torsional forces created by the torque of the main rotor. An autogyro is a type of helicopter that has a propellor that pulls it forward through the air. This forces air to go through the top main rotor(like on a helicopter) and this main rotor produces the lift for the autogryo.
