Lofty and Chop Jock.....so if the engine(s) are running, producing power, thus providing rotation to the Main Rotor Blades....what happens if the Rotor Blades contact some unmoving...substantial object? We would have to assume the Rotor Blades would slow down....thus be turning slower than the Pilot selected RPM...right?
After hitting that substantial object...what damage to the aircraft would occur?
Would the engines continue to run?
Would the engines, if still running, be trying to move the Rotor Blades, Rotor Head if no blades, Transmission if no Rotor Head?
