#rotor

• Wind turbine — A complex technical installation (wind turbine) consisting of a bladed rotor, a speed multiplier, and an electrical generator, structurally designed to capture the kinetic energy of the wind and transform it directly into useful electrical energy. It represents the fundamental pillar of modern wind power plants destined for clean and renewable energy production.
• Anterotor — Rotating assembly located at the front of an aerial vehicle, propulsion system, or industrial equipment, having the primary role of generating initial thrust or absorbing fluid kinetic air mass. In specialized helicopters or advanced drones, this front rotor provides pitch control.
• Autorotation — An aerodynamic mechanism and emergency flight regime of a helicopter or rotary-wing aircraft, where the main rotor spins exclusively under the action of the ascending airflow, without engine power. This physical phenomenon allows the aircraft to descend in a controlled manner and land safely in the event of a major failure or complete failure of the propulsion system.
