Jan 10, 2025 · A helicopter is an aircraft with one or more power-driven horizontal propellers or rotors that enable it to take off and land vertically, to move in any direction, or to remain stationary in the air.

Airbus helicopters are an essential tool for first responders, firefighters, public service operators and military customers flying critical missions across the globe.

Apr 20, 2022 · A helicopter's main rotor is the most important part of the vehicle. It provides the lift that allows the helicopter to fly, as well as the control that allows the helicopter to move laterally, make turns and change altitude. To handle all of these tasks, the rotor must first be …

Jan 10, 2025 · Helicopter - Rotor, Flight, Design: Unlike fixed-wing aircraft, the helicopter’s main airfoil is the rotating blade assembly (rotor) mounted atop its fuselage on a hinged shaft (mast) connected with the vehicle’s engine and flight controls.

Jan 11, 2023 · The science of a helicopter is exactly the same as the science of an airplane: it works by generating lift—an upward-pushing force that overcomes its weight and sweeps it into the air. Planes make lift with airfoils (wings that have a curved cross-section).

A helicopter is a type of rotorcraft in which lift and thrust are supplied by horizontally-spinning rotors. This allows the helicopter to take off and land vertically, hover, and fly forward, backward, and laterally.

Jun 7, 2023 · The helicopter is unarguably the most versatile flying machine ever created by humans. Helicopters have advanced to the point where they are essential in modern civilization. They have changed the aviation industry and expanded the range of possible uses for aircraft.

May 21, 2014 · A helicopter is a type of aircraft that uses rotating, or spinning, wings called blades to fly. Unlike an airplane or glider, a helicopter has wings that move.

Learn about helicopter types and models used in the military, firefighting, private charters, and more. We also cover popular models and use cases.

A helicopter is an aircraft that is lifted and propelled by one or more horizontal rotors—each of which comprises two or more rotor blades. Helicopters are classified as rotary-wing aircraft to distinguish them from fixed-wing aircraft (or airplanes). The word "helicopter" derives from the Greek words helix (spiral) and pteron (wing).
