The High-Speed Helicopter
Helicopters are good for hauling cargo and rescuing mountaineers.
But if you need to cover a long distance fast, you'd be better off
taking a plane, as helicopters today struggle to top 180 m.p.h.
(290 km/h). Sikorsky's X2 Technology helicopter aims to annihilate
that speed barrier. Unlike ordinary choppers, which pair a single
rotor on top with an antitorque tail rotor, the X2 has two main
rotors spinning in opposite directions and an airplane-like propeller
at the rear. This highly stable setup should allow the X2 to cruise
at a zippy 290 m.p.h. (467 km/h) — about the same speed as
some small turboprop planes. Don't expect to see this real-life
Airwolf hovering above your house anytime soon, however: the chopper
will be tied up in tests for the next decade.
