Helis, January 17, 2020 - Boeing announced successful first flight of a Chinook Block II helicopter equipped with the new Advanced Chinook rotor blades (ACRB).
These new blades adds 1,700 lbs / 771 kgs in lift capability. Developed by Boeing and the US Army, the ACRB is a new fully composite blade with a swept-tip design.
First flew on March 2019, the Chinook Block II is currently completing flight trials. Three Engineering and Manufacturing Development (EMD) aircraft were ordered for the flight test program which eventually will lead to more than 500 US Army’ CH-47F Chinook helicopters to be upgraded to this new configuration.
The CH-47F Block II new features also includes redesigned fuel tanks, a sturdier fuselage, and an improved drivetrain – all aimed at increasing lift capability, especially in high and hot operating conditions, providing commonality across the fleet and creating a foundation for affordable future upgrades.
