When was helicopters invented

Civilian versions of the craft were used by ranchers, police departments and the media. Hiller died in The first prototype, designated the HJ-1, flew in Hiller convinced the U. Navy to purchase three of the ramjet-powered helicopters, which the military dubbed the HOE During operation, the small helicopter proved to have some significant problems, however, including the rotor hitting ground personnel and the ramjets creating a bright ring of fire that could be seen easily during night operations.

Air Force and Navy crafted two design studies in for creating a fixed-wing vertical-takeoff-and-landing, or VTOL, aircraft. The goal of the project was to build a fighter that could protect convoys but not require a large landing area. In May , both Lockheed and Convair won contracts to build prototypes of the aircraft, which resembled squat fighter planes standing on their tails.

The Navy, however, gave Convair the only engine rated for vertical takeoffs and landings, allowing its aircraft — the XFY-1 Pogo — to make several vertical ascents and multiple transitions to horizontal flight.

The Lockheed XFV-1 used a less-powerful engine and never made a vertical takeoff, but was fitted with landing gear and made 32 horizontal flights. Kaman took the design and modified it in many ways, but most significantly, he added a jet-turbine engine, replacing the old reciprocating piston engines used by previous helicopters. The addition of the turbine engine made the Kaman K, and future helicopters, safer, more reliable and easier to maintain.

Turbine engines also increased performance, allowing the Kaman K to successfully fly through an intentional loop in March The design, however, had a significant flaw: It moved at only three-quarters of the speed of contemporary rotorcraft.

The idea was first suggested by engineer Charles Zimmerman, who called it the "flying shoes. Army in September to build a variant of the concept, dubbed the "flying platform. Of the six flying platforms built, the whereabouts of four are currently unknown.

Following experiences in the Korean War, the U. Army sought a medical evacuation helicopter for battlefield use. Bell Helicopter won the contract, and the Bell Model had its first test flight Oct. Designated by the Army as the HU-1H — thus the nickname "Huey" — and later designated the UH-1H, the helicopter became a veritable Swiss Army knife: ferrying the wounded, troops and cargo around Vietnam for all branches of the military.

The helicopter also changed the way that troops were mobilized for quick assaults on military targets. Nearly , wounded were transported by helicopter in the Vietnam War, 50 times more than the Korean War.

Army awarded Piasecki Aircraft a contract in to develop a fast, low-flying aircraft that could act as a "flying jeep. The second version of the flying jeep, or AirGeep as Piasecki called it, could fly at over 80 mph and carry five people.

Both versions of the AirGeep were true flying cars, not hovercraft, as they did not rely on so-called positive ground-effect forces to keep them aloft. They did, however, each have powered wheels for maneuvering on the ground. They were also very stable and could be used as weapons platforms. Yet, the Army eventually scuttled the project in favor of more-conventional battlefield helicopter designs. Army requested a new design for a utility transport helicopter in It granted the contract to Sikorsky for its S family of helicopters in December Designated by the Army as the UH "Black Hawk," the helicopter has a unique flattened appearance because of the requirement that it fit in the transport hold of a C Hercules cargo plane without removing the rotors.

The helicopter has a number of interesting safety features, including a crash-resistant cabin, landing gear that can cushion a hard landing, and two engines, either of which can keep the aircraft aloft on its own.

Today, the Black Hawk is the most popular helicopter in the U. Army requested proposals in for a helicopter gunship whose form was dictated less by the Vietnam War and more by the perceived need to destroy Soviet tanks.

Nearly a decade later, the Pentagon granted the contract to aircraft-maker Hughes to build the AH "Apache" helicopter. The development of the Apache was controversial, because it cost far more than previous contracts. During the Persian Gulf War, the helicopter performed well as both a tank killer and fast-assault vehicle.

The V Osprey used tilting rotors to vertically take off and then move to horizontal flight, where it would use its airplane-like aerodynamics to move faster and lift more.

Full-scale development began in with Bell Helicopter and Boeing working on different parts of the hybrid helicopter, known as a tiltrotor aircraft. Although the Osprey completed its first successful test in March , the Pentagon only signed off on production for the aircraft in The inventor says on his website that that the plane, dubbed the Hummingbird, will be able to perform maneuvers impossible for other aircraft — including the ability to hover like a hummingbird. A radio-controlled model of the plane flew in One engineer, Paul Moller, has designed three vehicles that he claims could fit the bill.

In , Moller International settled with the Securities and Exchange Commission for false and misleading statements. In , Stanley Hiller piloted the first helicopter flight across the United States , piloting a helicopter that he invented called the Hiller Young — of the Bell Aircraft company designed the Bell Model 47 helicopter, the first helicopter to have a full bubble canopy and the first certified for commercial use. Paul E. Williams U. Williams patented a helicopter named the Lockheed Model XH It was a compound experimental helicopter, and only 3 units were built.

His invention is the first helicopter as we know it today, and it managed to lift off the ground about 1 foot, for about 20 seconds.

Another French inventor by the name of Etienne Oehmichen is credited with the first helicopter flight carrying two passengers. He did this shortly after winning a prize of 90 for flying his helicopter following a triangular circuit of 1 Kilometer in length. In , toy helicopters were made and were powered with rubber bands, which some of us are old enough to remember playing with. Nine years earlier, a small steam-powered helicopter was invented, but it was made out of new metal and aluminum and never got off the ground.

In , an unmanned steam-powered vehicle rose to 39 feet then hovered for a few seconds in the air. It even took off vertically like helicopters of today do. In , an inventor in Paris built and then flew an electric version of a helicopter with success. In July of in Germany, the maiden voyage of a helicopter took place and even carried humans from one place to another.

The event was later depicted in a movie, although it has since been lost to time. Even Thomas Edison had an interest in helicopters. In the late s he was given money to experiment with the helicopter, but the aircraft he invented exploded and even caused serious burns to one of the workers. Later, a Slovak inventor took what Edison had learned and applied it to his own invention.

Edison attempted to improve on his helicopter in , but the one he invented that time never flew.
