Ch47 ground resonance
WebJan 6, 2024 · If the Rotor RPM (N R) is low, the corrective action to stop ground resonance is to shutdown the engines immediately and fully lower the thrust to place the blades in low pitch. Shutting down the engines reduces the N R , hence the lift of the blades. The aft rotor head is equipped with centrifugal droop stops which provide … http://www.chinook-helicopter.com/history/aircraft/C_Models/74-22292/74-22292.html
