History
The Vertol 107 was developed for the tender of the U.S. Army for a transport helicopter and made its first flight under the name YHC -1A on 22 April 1958. Overall, it can carry 25 passengers. The hull was designed so that on the rear ramp bulky cargo or light off-road vehicles may be invited. As a Navy helicopter he has the ability to land on water with minimal swell, without the need for additional swimmers must be attached. The hull is sealed accordingly. In order to reduce crew workload automatic trim and flying blind instruments are installed.
The U.S. Army was interested only in the larger successor model, the CH -47 Chinook. The U.S. Navy, however, took interest in the CH/UH-46, whereupon the improved CH/UH-46 D was developed with new turbines. Through repeated improvements of the engines and avionics of the F CH/UH-46 was currently running the E program, which provides to bring all A- models on the E- standard. The Navy studied the helicopter 4 September 2004 finally made , the USMC is planning a complete replacement by the tilt rotor Bell - Boeing V-22 in 2014. Until the last production in February 1971 524 Sea Knights were built.
Outside the U.S., the CH- 46 CH -113 Labrador and CH- 113A Voyageur used in the Canadian Navy and Coast Guard under the designation. In the Swedish Navy under the name HKP -4, both models use Rolls- Royce turbines. Other users are Japan (military ), Saudi Arabia and Thailand, as well as various airlines such as New York Airways and Pan Am.
Kawasaki produces the CH -46 under license and sells it under the name KV-107/II to civilian operators, where it is used among other things as rescue and fire- fighting helicopter.
