Every time I rode in a Chinook I always felt as though it was going to tear itself apart sitting on the ground while loading and unloading. Also, one of the weirdest feelings is riding in a helicopter and it's flying diagonally (not quite straight not quite sideways) as it relates to the orientation of the aircraft that throws your sense of direction off. As an infantryman, I'll just walk.

This is true and not true at the same time, the clip of the Chinook destructing was a test done by the US Army. The reason that happens is due to a fault in the AVCS (Active Vibration Control System) there are a few built into the helicopter that measure the vibration and add their own vibration to stabilize the bird while on the ground and in flight.

That’s our tax dollars hard at work!! The US Army and Boeing did that test to determine the effectiveness of an anti-vibration system that was being developed at the time. If I remember correctly it was designed to detect vibrations and then use vibrations to cancel out the vibrations that were initially detected. But it’s exactly what happens when ground resonance is not dealt with by immediately getting the aircraft off the ground!!

Only possible on odd number bladed helicopters, specifically 3 bladed machines. 5 bladed machines like an MD500 do not create enough imbalance between any 2 blades to cause significant ground resonance. Short answer, even number of blades or 5 plus is the way to go.
@chippyjohn1

@@Levi-wk2hg The MD500 can experience ground resonance, but less likely. Smaller lighter blades that are spinning at a higher rpm are less likely to initiate ground resonance, but not impossible. The MD500 has large dampers built into the landing gear for this reason, as well as hard landings.

@krisholden5365

Pre-flight checks have absolutely nothing to do with ground resonance. An aircraft that’s in absolutely perfect working condition can experience ground resonance. It’s a phenomenon that is inherent in certain types of rotor systems and, as stated in the video, with aircraft that have more than two main rotor blades. It’s something that we train to recognize and identify as an emergency with the emergency procedure being to bring the aircraft into a hover immediately upon recognition of the early stages of ground resonance. As soon as the landing gear is off the deck, the resonance will cease and you can gently return the aircraft to the ground. It’s not all that common in most aircraft but there are some designs that are known to experience it much more frequently than others.

The type of rotor system that the Huey (all Bell models, if I’m not mistaken) has is called a teetering rotor system. This is common on a lot of helicopters from a good number of manufacturers. This is the system that allows for mast bumping, which is what you are talking about. Essentially, the aircraft is hanging below the rotor system. Control inputs cause the rotor disc to change its orientation and the aircraft follows shortly after. The issue with this is that the rotor system can become “unloaded” during certain low-g conditions and then your control inputs will not have any discernible effect on the aircraft while the rotor is unloaded. This caused early pilots to put gobs of control inputs into the system and then the rotor disc would essentially travel beyond its intended limits and smack into important components like the mast and the p/c links and the swashplate and everything near it would sort of mush together and then, suddenly, you’re a glider. That’s never a good thing to be in a helicopter.

That is actually something different. Sympathetic Resonance is the main and tail rotor vibrations amplifying each other (usually in a lower "avoidable" RPM range) and can be destructive when allowed to stay in that range for too long.
