The science of an airplane: it works by generating lift-an upward-pushing force that overcomes its weight and sweeps it into the air. The science of a helicopter is exactly the same as Advantages and disadvantages of helicopters.How Sikorsky designed the modern helicopter rotor.Picture by Shannon Renfroe courtesy of US Navy and Flickr.
