What will helicopters look like in the future?
UNLIKE a helicopter, aeroplanes are inclined to fly, Harry Reasoner, a veteran American newsman, wryly observed after watching choppers in action during the Vietnam war. He wrote:
For now, companies that make helicopters think their machines have a long life ahead of them. Batteries are currently unable to provide electric rotorcraft with extended flight times or the ability to carry heavy loads. And many helicopter missions are still likely to require crew on board—think of winchmen for an air-sea rescue. Nor would most hovering drones stand a chance in the intense storms and blizzards that helicopters sometimes have to fly into.
An older and bigger tilt-rotor called the V-22 Osprey is produced by Bell in partnership with Boeing. This too is faster and can travel farther than a standard helicopter. It is used by the US Marines. The V-22, however, tilts both its rotors and engines. The V-280 simplifies this design and reduces the amount of weight that has to be rotated by having the engines remain in place and tilting only the driveshafts and rotors.
