CH‑47 “Chinook”
CH‑47 “Chinook”
The Boeing CH-47 “Chinook” has tandem rotors,
and twin turbine engines. The Chinook is powered
by two turboshaft engines, mounted on either side of
the helicopter’s rear end and connected to the rotors
by driveshafts. The counter-rotating rotors eliminate
the need for an anti-torque vertical rotor, allowing
all power to be used for lift and thrust. If one engine
fails, the other can drive both rotors. It was originally
designed for the U.S. Army in the late 50’s as a heavy
lift helicopter and was used extensively in Vietnam. The
civilian version of the CH-47 is the Boeing 234.
