Rotorcraft - Wikipedia
网页A rotorcraft or rotary-wing aircraft is a heavier-than-air aircraft with rotary wings or rotor blades, which generate lift by rotating around a vertical mast. Several rotor blades mounted on a single mast are referred to as a rotor .
Helicopter rotor - Wikipedia
网页On a helicopter, the main rotor or rotor system is the combination of several rotary wings (rotor blades) with a control system, that generates the aerodynamic lift force that supports the weight of the helicopter, and the thrust that counteracts aerodynamic drag in …
What is the difference between a propeller and a rotor?
网页Short answer: A propeller is used to propel something, the force at stake being called thrust. Thrust is usually horizontal (but not always, think about rockets). This device comes from the navy domain. A rotor of a rotorcraft is used to control anything, including the altitude, the generated force being called lift.
Main Rotor System | Flight-Study
网页Main rotor systems are classified according to how the main rotor blades are attached and move relative to the main rotor hub. There are three basic classifications: semirigid, rigid, or fully articulated. Some modern rotor systems, such as the bearingless rotor system, use an engineered combination of these types.
Helicopter - Rotor, Flight, Design | Britannica
网页2024年8月12日 · 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.
2.1.2: Rotorcraft - Engineering LibreTexts
网页2024年6月26日 · A rotorcraft (or rotary wing aircraft) is a heavier-than-air aircraft that uses lift generated by wings, called rotor blades, that revolve around a mast. Several rotor blades mounted to a single mast are referred to as a rotor.
An Introduction to the Different Types of Rotorcraft
网页2021年5月19日 · The most common type of rotorcraft is a helicopter. Even if you’re unfamiliar with rotorcraft, you’ve probably seen a helicopter before. Helicopters are aircraft that feature engine-driven rotor that spins during flight. With their spinning rotor, they can fly forwards, backwards, upwards and downwards.

Helicopter Aerodynamics - Aircraft Theory of Flight - Aircraft …
网页One method that is used on a helicopter to counteract torque is to place a spinning set of blades at the end of the tail boom. These blades are called a tail rotor or anti-torque rotor, and their purpose is to create a force, or thrust that acts in the opposite direction of the way the helicopter is trying to rotate.
