In this episode, we examine how the Wright Brothers’ first powered flight in 1903 laid the groundwork for helicopters and vertical lift aircraft. We detail how manufacturers like Sikorsky, Bell Helicopter, Airbus Helicopters, Leonardo Helicopters, and Russian Helicopters have advanced rotorcraft design. The script explains how helicopters generate lift with spinning blades, manage drag, thrust, and weight, and why they do not need runways. It covers how autorotation works to allow emergency landings when engines fail. Real-world uses are highlighted, including air ambulances, military transport, firefighting, live traffic reporting, and offshore oil operations. The episode also discusses future developments like tiltrotor aircraft and electric or hybrid engines aimed at expanding helicopter performance and reducing environmental impact.
