CH-47F Update
A recent article in Defense News covering development of the CH-47F Block II
https://www.defensenews.com/land/202...to-major-test/ There was a lot of surprise when the Army passed on mass production of the latest variant of the Chinook, this article starts to flesh out the reasons for this decision. The main take away is: The new Advanced Chinook Rotor Blade, or ACRB, on the CH-47F Block II aircraft “produces excessive vibrations in ground, hover, and forward flight that may cause a safety of flight risk,” the report stated. “Aircrews reported prolonged fatigue and other physiological conditions due to excessive vibrations following a developmental test flight using the redesigned ACRB’s.” This program can be added to Boeing’s ever growing list of recent design failures (737 Max, KC-46, Starliner, SB-1: etc). |
