| 'The Boeing CH-47 Chinook is a versatile, twin-engine, tandem rotor heavy-lift helicopter. The contra-rotating rotors eliminate the need for an anti-torque vertical rotor, allowing all power to be used for lift and thrust. Its top speed of 170 knots (196 mph, 315 km/h) was faster than 1960s, and even many contemporary, utility and attack helicopters. Its primary roles include troop movement, artillery emplacement and battlefield resupply. There is a wide loading ramp at the rear of the fuselage and three external-cargo hooks. It has replaced the CH-54 Tarhe as a lifter.' for more detail,pls click en.wikipedia.org |
