 * Leonardo da Vinci made the first blueprints for what looked like a helicopter, but was described as an “aerial screw”. ****Until recently, helicopters were the only flying vehicle that could achieve vertical lift-off. ****Modern day helicopters are used for carrying things, for military, for rescuing, and for just plain old transportation. ****Leonardo da Vinci said that he designed the helicopter for transportation. ** ** The rotor on the helicopter is what causes the forward motion. ** **Leonardo’s design did not work. **


 * Helicopters have three main rotors. ****At first the helicopter didn’t look like it would fly. ****A helicopter has four flight control inputs: the cyclic, the collective, the anti-torque pedals, and the throttle. ****The inventor of the first working helicopter was Paul Cornu. ****A helicopter has three basic flight conditions: hover, transition from hover to forward flight, and forward flight. ****Paul Cornu’s design stayed in the air for about one minute. ****The **** main limitation of a helicopter is that it bad at ****landing. ****Paul Cornu gets the credit for creating the helicopter. **[[image:realorfake2013/fake_helicopter_crash.JPG width="336" height="252" align="left"]]
