How Do Helicopters Fly Without Wings?
Engineering tons of metal to fly straight up is no easy feat. Here's how helicopter blades make vertical flight a reality. Why Flying Makes You Feel Sick ...
==========
Helicopters kinda look like fat bugs lying on their backs flailing their legs around… so how exactly can they fly with more precision than an airplane? Airplanes fly because their wings are curved on the top and flat on the bottom, allowing them to harness the Bernoulli Principle. With speed, the air passing over the wing is less dense than the air under it, creating lift. Helicopters have rotor blades that also create lift. As the blades spin they move the air. Less dense air passes over the blades with denser air passing underneath it. Put that way it sounds simple, but it’s far more complicated, because while airplanes get lift naturally by moving through the air helicopters have to constantly generate it themselves. This is how they can takeoff and land vertically, and also fly bac...
