They derive lift and propulsion from the rotor
No, airplanes need wings for lift. - Now having said that, aircraft can fly without wings, as they include helicopters, dirigibles and balloons which have alternate ways of gaining lift.
Humans. We don't have wings, but we build airplanes and helicopters.
A helicopter is an aircraft without fixed wings. Helicopters can also be known as rotorcraft.
i dunno the one without wings but i know that the one with wings is a bat! A flying squirrel is a mammal without wings.
Dragonflies cannot fly without wings.
Well, there are helicopters, paragliders, and balloons.
yes. why? because it doesn't have wings.
wings
wings
Because their wings/rotors are able to create an upward force bigger or equal to the pull of gravity.
A helicopter flies do to rotorblades rotating. Most helicopters have two rotorblades, one to lift the helicopter off the ground, and the second, most commonly found on the tail, for stability.
Some creatures can fly without wings by using other methods such as gliding, jet propulsion, or buoyancy.
