Top 5 Facts: Helicopters

Da Vinci

The first reference to a rotor system is credited to inventor Leonardo da Vinci, who designed an ‘aerial screw’ in 1480. No full-scale variant was constructed during his lifetime.

Steamed

The word ‘helicopter’ was coined by French inventor Gustave de Ponton d’Amécourt, who used it to name his small, steam-powered rotorcraft.

Untethered

The first helicopter to achieve completely untethered flight was the Cornu in 1907, which managed to hover one foot above the ground for 20 seconds.

Fastest

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).

Phileas

The current world record speed for an eastbound round-the-world helicopter trip is 85 mph (137 kph). The record was set by Edward Kasprowicz in an Augusta A109S Grand.

    Fascinating stuff, but is that right about Phileas? 220mph is 136kph?

      Apologies, John, that was incorrect. The speed has now been changed. Cheers for pointing it out :-)

    Sorry, couldn’t help it. Even in these days of text-speak and Twittering, I am condemned to have errors jump out at me from the page.
