Boeing CH-47 Chinook

The Boeing CH-47 is a twin engine helicopter with tandem rotor design for transportation of troops and weapons. It is also used for medical evacuation, disaster relief, rescue missions, fire fighting, heavy construction and civil development, parachute drops and aircraft recovery.

The initial model 107/YHC-1A was rejected by the US Army because it was too small for the needs of the Army. They needed a large helicopter that could carry heavy cargo, military troops and other equipments. The CH-47 Chinook became the best option for the US Army. It meets the tactical and combat support mission needs of for military forces all over the world

The CH-47A Chinook started its activity in Vietnam with the U.S. Army 1st Cavalry Division in 1965. The CH-47B Chinook was used for the transportation of US troops by the U.S. Army 1st Cavalry Division in Vietnam. It was also used in the Gulf War in 1991, where the CH-47D variant served in the Desert Shield and Desert Storm Operations. Other operations where the CH-47 Chinook was used are the Operation Iraqi Freedom and the Operation Enduring Freedom in Afghanistan. The tasks of the CH-47 Chinook in these operations were troop insertion into fire bases, air assault missions, and later transportation of food, water and ammunition.

The CH-47D saw wide use in Operation Enduring Freedom in Afghanistan and Operation Iraqi Freedom in Iraq. The Chinook was used in air assault missions, inserting troops into fire bases and later bringing food, water, and ammunition. For the CH-47 Chinook protection the US Army uses attack helicopters like the Apache to escort the Chinook.

It is typically escorted by attack helicopters such as the Apache for protection. The CH-47D was particularly useful in the mountainous terrain of Afghanistan where high altitudes and temperatures limited the use of the Black Hawk.

The latest variant of the CH-47 Chinook is the CH-47F which became an advance multimission helicopter and contains a fully integrated digital cockpit management system. Here are the main characteristics of the CH-47F Chinook: Length: Fuselage - 52.0 ft. (15.9 m) Incl. Rotors - 99.0 ft. (30.18 m);Width: 12.42 ft (3,78 m);
Rotor Diameter: 60 ft. (18.29 m);Height: 18.92 ft. (5.77 m); Propulsion: 2 Honeywell 55GA714A
engines, 4,733 shp (3,529 kW) each; Speed: 155 kt (287 km/h); Fuel: 1,034 gal. (3,914 L); Service Ceiling: 20,000 feet; Useful Load: 24,000 lbs. (10, 886 kg); Mission Radius: 200 nm (370.4 km); Max Gross Weight: 50,000 lbs. (22,668 kg); Mission: Transport of troops, artillery, ammunition, fuel, supplies, water in support of combat operations, and civil and humanitarian relief Service Customer: U.S. Army, in service since 1962. The Chinook's powerplant is based on two Textron Lycoming T55-L-712 turboshafts each rated at 3,750 shp for takeoff and 3,000 shp for continuous running

The CH-47 Chinook uses for attack and defensive the M134 7.62 mm (0.308 in) minigun, and M240 7.62 mm (0.308 in) machine gun.

The CH-47 Chinook has two turboshaft engines, positioned on each side of the helicopter's rear end and connected to the rotors by driveshafts. Because of the counter rotating rotors there is no need for an anti-torque vertical rotor. Thus the CH-47 Chinook can concentrate all power for the lift and thrust. The two engines are complementary (if one fails the other can drive both rotors.

Boeing has build also built a commercial version of the Chinook: , the Boeing -Vertol Model 234, used around the world for construction, forest fire fighting, logging and supporting petroleum exploration operations. Here is a list of the civilian models of the Chinook: model 234LR (Long Range) -used for commercial transportation (all-passenger, all-cargo or cargo-passenger); model 234ER (Extended Range) -used for commercial transport; model MLR (Multi Purpose Long Range) -used for commercial transport version; model 234UT (Utility Transport) -used for utility transportation; model 414 (also known as the CH-47D International Chinook) -this is the international export version of the CH-47D.

The CH-47 Chinook came in different improved models starting with CH-47A. The effectiveness of the Chinook has been continually upgraded by successive product improvements, the CH-47A, CH-47B, CH-47C, CH-47D, MH-47D, MH-47E, CH-47F, MH-47G and HH-47. Many product improvements have more than doubled the Chinook's lift capacity since its inception.

The amount of load a cargo helicopter can carry depends on the model, the fuel on board, the distance to be flown, and atmospheric conditions. It was in 1976 the Army recognized that that the Chinook fleet was rapidly reaching the end of its useful life and signed a contract with Boeing to significantly improve and update the CH-47. A total of 472 CH-47A, B, and C model Chinooks were converted to CH-47D's. Current versions of the CH-47 Chinook are being produced under license in Italy and Japan in addition to the CH-47D and MH-47E being produced in the United States. User countries include Australia, Egypt, Greece, Iran, Italy, Japan, Morocco, Netherlands, Singapore, South Korea, Spain, Thailand, Turkey, UK and USA.

The US Army and all other Forces around the world have found that the CH-47 Chinook is a very helpful aircraft, which proved to be a last minute successful partner in the combat field.
