Boeing has developed a new rotor blades for Chinook Block 2. With the help of advanced manufacturing technologies and material technology, new composite rotor blades of Chinook Block 2 to provide an additional lifting capacity of 680 kilograms.
According to Chuck Dabundo's statement who is Boeing Cargo Helicopters and H-47 Program Manager, Block 2 blades consists of a combination of three separate airfoils, rather than a single airfoil, as opposed to Block 1 blades. The performance of the blades called ACRB (Advanced Chinook Rotor Blade) is further enhanced by the new curved rotor tip. A more aerodynamic design gives the rotors a higher lift, while the design provides less drag force. This development will also increase the fuel efficiency of the helicopter.
