How do helicopter fly?
Answers
Answer:
by the fuel and power.....
Answer:A helicopter remains stationary by balancing the external forces. There are no horizontal forces, as the helicopter is not moving left or right, so there is no drag or horizontal thrust. The blades generate a vertical lift, and when this is exactly balanced with the force of gravity, the helicopter remains stationary
In addition to moving up and down, helicopters can fly forward, backward and sideways. This kind of directional flight is achieved by tilting the swash plate assembly with the cyclic, which alters the pitch of each blade as it rotates. As a result, every blade produces maximum lift at a particular point.
In a few hours, I'll be in the cockpit of a Sikorsky S-76 helicopter outfitted with the company's six-year-old Matrix autonomous flight technology, which was born out of a DARPA program, letting a computer take me on a guided tour of the Housatonic River from about 3,000 feet in the air.
