he Boeing CH-47 Chinook is an American twin-engine, tandem-rotor, heavy-lift helicopter developed by American rotorcraft company Vertol and manufactured by Boeing Vertol (later known as Boeing Rotorcraft Systems). The CH-47 is among the heaviest lifting Western helicopters. Its name, Chinook, is from the Native American Chinook people of modern-day Washington state. The Chinook was originally designed by Vertol, who had begun work in 1957 upon a new tandem-rotor helicopter, designated as the Vertol Model 107 or V-107. Around the same time, the United States Department of the Army announced its intention to replace the piston engine-powered Sikorsky CH-37 Mojave with a new, gas turbine-powered helicopter. During June 1958, the Army ordered a small number of V-107s from Vertol under the YHC-1A designation; following testing, it came to be considered by some Army officials to be too heavy for the assault missions and too light for transport purposes. While the YHC-1A would be improved and adopted by the Marine Corps as the CH-46 Sea Knight, the Army sought a heavier transport helicopter, and ordered an enlarged derivative of the V-107 with the Vertol designation Model 114. Initially designated as the YCH-1B, on 21 September 1961, the preproduction rotorcraft performed its maiden flight. In 1962, the HC-1B was re-designated CH-47A under the 1962 United States Tri-Service aircraft designation system. he Airbus Helicopters H215 (formerly Eurocopter AS332 Super Puma) is a four-bladed, twin-engine, medium-size utility helicopter developed and marketed originally by Aérospatiale, later by Eurocopter and currently by Airbus Helicopters. It is a re-engined and more voluminous version of the original Aérospatiale SA 330 Puma. First flying in 1978, the Super Puma succeeded the SA 330 Puma as the main production model of the type in 1980. Since 1990, Super Pumas in military service have been marketed under the AS532 Cougar designation. In civilian service, a next gener
