ADVANCES IN DESIGN
The most recent high-production variant of Chinook is the CH47F. Equipped with a redesigned modernised airframe, Common Avionics Architecture System (CAAS) cockpit that improves crew situational awareness and the Digital Automatic Flight Control System (DAFCS), which offers enhanced flight-control capabilities for the multitude of conditions in which the helicopter is used, quicker pilot decisions and more accurate handling can be achieved. A reconfigured cabin can be customised with troop seats, litters or auxiliary fuel for any mission. Triple cargo hooks and a broad centre of gravity range make for flexible load lifting. Mounts for fast roping, skis, rescue hoist and three gun positions make the latest CH-47FS highly versatile.
“QUICKER PILOT DECISIONS AND MORE ACCURATE HANDLING CAN BE ACHIEVED”
Single rotor helicopters require a torque regulating vertical rotor, such as a tail rotor, to counteract the yawing movement produced by the single large rotor. The Chinook’s counter-rotating tandem rotors eliminate this requirement, releasing most of the power for lift and thrust and avoiding other tail rotor issues. A small percentage of power is lost due to the transmission complexity and the overlapping rotors A night view of a US Army CH-47 A US Army CH-47 in Botswana.
