The RC huey helicopter are unarguably one of the most popular helicopters, which was developed by the Bell Helicopters. It was generally referred to as “Huey” and was flown in the year 1956 to serve the US army and other military nations and have been in existence since then. This RC huey helicopter became famous due to its usage in the heavily fought Vietnam war and has featured in many war-movies. The RC huey helicopter has many distinctive features consisting of its twin-blade rotor, round-nose shaped appearance and the loud sound it creates when it is in motion. This helicopter makes these noisy sounds as when it is in forward-flight, the tip of the rotor blade tends to break the sound speed, making a tiny-sonic-boom
When was the RC Huey Helicopter first seen?
The prototype model of this RC huey helicopter was seen its flight in 1956 and after that several turbine-powered-aircraft was ordered by the US military. In the beginning it was designated the H-40 following the USAF designating-system, but later it was revised to HU-1. This aircraft was officially called as “Iroquois”, but the huey name was more popular. The RC Huey helicopter was a huge success no doubt, but the army wanted an improved version so as to be able to ferry more-troops. Bell suggested that the HU-1B-fuselage should be stretched by 41 inches, which will result in more space to accommodate upto 4 seats. With these modifications the seating-capacity increased to 15, inclusive of crew. This enlargement of cabin could accommodate almost 6 stretchers and a para-medic, which is twice than the previous models. In the earlier version of the huey helicopters, sliding-side-doors were present with just one window, but in the improvised version, there were big doors fitted with 2 windows, in addition of a small-hinged-panel along with an optional-window, so as to give access to the cabin. The doors and hinged panels could be removed faster, thereby making way for the RC huey helicopter to be flown in like ‘doors-off’-configuration.
The RC huey helicopters became a status symbol
Further in 1966, Bell-installed 1400 kw T53L-13 engine to give more power to the aircraft. The pilot-tube was re-located to the roof of the cockpit from the nose, so as to prevent any damage while landing. These models was designated as UH-1H. The single-engine UH-1 was followed by the twin.engine UH-1N-twin-huey and later to UH-1Y-venom. The UH-1Y has an elongated cabin, with 4-rotor blade and 2 extra pwerful GE-T-700 engines. The UH-1s components include engine, rotor, main-rotor-blades, transmission, tail-rotor-drive-shaft, and gear-boxes of 42 degree and 92 degree respectively. The transmission consists of planetary-style and minimizes the engine’s-output to almost 324rpm at the main-rotor. The tail rotor drives from the main-transmission through the 2-directional-gearboxes, which is responsible in providing a tail-rotor-speed of almost 6 times than that of the main-rotor so as to increase the tail-rotor efficiency of the RC Huey Helicopter.
