NASHVILLE, Tenn. — The U.S. Army has decided to shelve its Advanced Chinook Rotor Blades it was developing as part of the Boeing-manufactured CH-47F cargo helicopter’s latest upgrades due to issues that cropped up during testing, according to Brig. Gen. Robert Barrie, the program executive officer for Army aviation.
In 2020, the service was dealing with excessive rotor blade vibrations from the ACRBs as it headed into a limited-user test scheduled for early 2021, so the service decided to cancel that test until it had worked through the issues.
A report from the Pentagon’s chief weapons tester noted vibrations present in ground, hover and forward flight that could pose “safety of flight risk.” Boeing pushed back against the claim it posed a safety risk, but the company did acknowledge vibration issues.
