Helicopters were developed and built during the first half-century of flight, with the Focke-Wulf Fw 61 being the first operational helicopter in 1936. Some helicopters reached limited production, but it was not until 1942 that a helicopter designed by Igor Sikorsky reached full-scale production, with 131 aircraft built. Though most earlier designs used more than one main rotor, it is the single main rotor with anti-torque tail rotor configuration that has become the most common helicopter configuration. Tandem rotor helicopters are also in widespread use due to their greater payload capacity. Coaxial"

History of Trumbull, Connecticut Trumbull, a town in Fairfield County, Connecticut, in the New England region of the United States, was originally home to the Golden Hill Paugussett Indian Nation, and was colonized by the English during the Great Migration of the 1630s as a part of the coastal settlement of Stratford. In May 1725, the northwest farmers of Stratford"
"Berliner Helicopter The Berliner Helicopters were a series of experimental helicopters built by Henry Berliner between 1922 and 1925. The helicopters had only limited controllability but were the most significant step forward in helicopter design in the USA until the production of the Vought-Sikorsky VS-300 helicopter in 1940. The 1922 flights of the Berliner and the de Bothezat H1 were the first by manned helicopters. Emile Berliner, an inventor famous for his invention of the flat gramaphone record, had experimented with intermeshing helicopters as early as 1907. The initial design was underpowered and called for a lighter engine. Berliner developed"

This resulted in three prototypes. The first was built in 1927 and made its first flight in 1929. Nicolas Florine built a helicopter with two rotors in tandem, turning in the same direction. To balance the reaction torques, he used his principle of inclining the axes of rotation of the rotors with respect to each other. After the implementation of scale models, one of which weighed 36 kg and left the ground"

Patents were granted to von Baumhauer for his cyclic and collective controls by the British ministry of aviation on 31 January 1927, under patent number 265,272. In 1927, Engelbert Zaschka from Germany built a helicopter, equipped with two rotors, in which a gyroscope was used to increase stability and serves as an energy accumulator for a gliding flight to make a landing. Zaschka's plane, the first helicopter, which ever worked so successfully in miniature, not only rises and descends vertically, but is able to remain stationary at any height."

Newton Williams of Derby, Connecticut, had lifted its operator (Williams) ""from the ground on three occasions"" at Berliner's laboratory in the Brightwood neighborhood of Washington, D.C. Between 1907 and 1926, Berliner dedicated himself to improving the technologies of vertical flight through the development of a light-weight rotary engine, which he improved upon throughout the 1910s and 1920s. With R.S. Moore, also a Scientist and Inventor, as his chief assistant, Berliner obtained automobile engines from the Adams Company in Dubuque"
"Wright brothers to pursue the dream of flight. In 1861, the word ""helicopter"" was coined by Gustave de Ponton d'Amécourt, a French inventor who demonstrated a small steam-powered model. While celebrated as an innovative use of a new metal, aluminum, the model never lifted off the ground. D'Amecourt's linguistic contribution would survive to eventually describe the vertical flight he had envisioned. Steam power was popular with other inventors as well. In 1878 the Italian Enrico Forlanini's unmanned vehicle, also powered by a steam engine, rose to a height of , where it hovered for some 20 seconds after a vertical"

In 1911, Slovenian philosopher and economist Ivan Slokar patented a helicopter configuration. The Danish inventor Jacob Ellehammer built the Ellehammer helicopter in 1912. It consisted of a frame equipped with two counter-rotating discs, each of which was fitted with six vanes around its circumference.

The first flight turned out to be surprisingly successful for a machine that had been built without prototyping.
