CHAPTER 1. Introduction: A History of Helicopter Flight. The idea of a vehicle that could lift itself vertically from the ground and hover motionless in the air was probably born at the same time that man first dreamed of flying. Igor Ivanovitch Sikorsky (1955) 1.1. Rising Vertically. Aerodynamics is the science of all flight.
Overview. During the past sixty years since their first successful flights, helicopters have matured from unstable, vibrating contraptions that could barely lift the pilot off the ground, into sophisticated machines of extraordinary flying capability. They are able to hover, fly forward, backward and sideward, and perform other desirable maneuvers.

29 sty 2019 · Coaxial helicopters, tiltrotor aircraft, and compound helicopters are all flying today. Quadcopter helicopters pioneered as early as 1907 in France, and other types of multicopter have been developed for specialized applications such as unmanned drones.
16 paź 2023 · The iconic image of a helicopter, its blades whirring as it gracefully maneuvers through the air, is a testament to human ingenuity and a revolution in flight. But the journey from dream to reality wasn’t always smooth, filled with countless experiments, breakthroughs, and even a few setbacks.
4 paź 2019 · One of aviation's greatest designers, Sikorsky began work on helicopters as early as 1910. By 1940, Sikorsky's successful VS-300 had become the model for all modern single-rotor helicopters. He also designed and built the first military helicopter, the XR-4, which he delivered to the U.S. Army in 1941.
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, to hover, and to fly forward, backward and laterally.
