The CH-47 Chinook, the workhorse of the US Army, is manufactured by the Boeing Vertol company. The Chinook has served as the prime mover for the US Army and other military forces for decades. Its principal missions include transport of troops, artillery, ammunitions, fuel, water, barrier materials, supplies and equipment on the battlefield. Other missions include medical evacuation, aircraft recovery, fire fighting, parachute drops, heavy construction, civil development, disaster relief, and search and rescue. In the US Army National Guard and among international customers, Chinooks often expend the majority of their flight hours on these latter missions. The CH-47 is a twin-engine, tandem rotor helicopter designed for transportation of cargo, troops, and weapons during day, night, visual, and instrument conditions. The aircraft fuselage is approximately 50 feet long. With a 60-foot rotor span, on each rotor system, the effective length of a CH-47 (with blades turning) is approximately 100 feet from the most forward point of the forward rotor to the most rearward point on the aft rotor. Maximum airspeed is 170 knots with a normal cruise speed of 130 knots. However, speed for any mission will vary greatly depending on load configuration (internal or external), time of day, or weather conditions. CH-47 Chinook (wallpaper 4).

The minimum crew for tactical operations is four, two pilots, one flight engineer, and one crew chief. For more complex missions, such as NVG operations and air assaults, commanders may consider using five crew members and add one additional crew chief. Development of the medium lift Boeing Vertol (models 114 and 414) CH-47 Series Chinook began in late 1956, when the Department of the Army announced plans to replace the H-37 helicopter, which was powered by piston-driven engines, with a new, turbine-powered aircraft. A design competition was held and, in September 1958, a joint Army-Air Force source selection board recommended that the Army procure the Boeing Vertol medium transport helicopter. However, the necessary funds to proceed with full-scale development were not available and the Army vacillated in its design requirements. There were those in the Army who felt that this new helicopter should be a light tactical transport aimed at the mission of the old H-21's and H-34's and, consequently, sized for approximately fifteen troops. Another faction believed that the new transport should be much larger to serve as an artillery prime mover and have minimum interior dimensions compatible with the Pershing Missile system. This "sizing" problem was a critical decision. CH-47 Chinook (wallpaper 4). CH-47 Chinook aircraft images wallpaper gallery 4. CH-47 Chinook airplane pictures and images collection 4.
