Interesting Helicopter and Fixed-wing Facts for Dickinson, ND

Igor Sikorsky is considered to be the \father of helicopters not because he invented the first. He is called that because he invented the first successful helicopter

The record for the fastest helicopter in the world is held by the Sikorsky X2 which during a flyby over Florida United States clocked 258mph (416kph). But this was beaten recently. On June 7th 2013 the X3 blew through the previous air speed record for helicopters by cruising at 255 knots (293 MPH) during a 40-minute flight over Southern France near Istres.

Helicopter Facts for Dickinson, ND

In order to fly, an object must have “lift”. Lift is what pushes something upwards. Lift is made by wings (rotors). Wings have a curved shape on top and are flatter on the bottom. This specific shape makes air flow over the top of the wing faster than under the bottom of the wing. The faster air on top of the wing makes suction on the top of the wing and the wing moves up. Airplanes get lift from their wings. A helicopter's rotor blades are spinning wings. A helicopter moves air over its rotor by spinning the blades. The rotor makes the lift that carries the helicopter up. One problem associated with helicopter rotor blades occurs because airflow along the length of each blade differs widely. This means that lift and drag fluctuate for each blade throughout the rotational cycle, thereby exerting an unsteadying influence upon the helicopter. The autogiro had a rotor that functioned something like a windmill. Once set in motion by taxiing on the ground, the rotor could generate supplemental lift; however, the autogiro was powered primarily by a conventional airplane engine.
