  • actualy it was intentional to show what one little missing tool, from a kit could do to an aircraft. notice the hull markings. this is why they dont let the mechanics leave for the day unless a full tool inventory is done

  • It's a demonstration of ground resonance, please move on...

  • TEST RESULTS:

    FAILURE

  • Bit of duct tape

  • well atleast now they know that helicopters are better off in the air

  • people. If it was being held down, the ropes would be taught. no slack... I think it was because the back rotor was off balance. If you watch the rear rotor spin, you will see that one of the blades is not in line with the other ones. Its extremely subtle, but not much is needed to throw the chopper off balance. It is ever so slightly higher than the other two, and the difference effed it all up. That one blade screwed up the balance of the entire machine, hence the shaking.

  • @AddictedToStangs , yes absolutely, i was dubious about the ground resonance thing and thought the rear rotor looked off balance, the transmission is the part that suffers most, thats some hot fucked pieces laying broken!! well spotted mate, nice to see an intelligent comment rather than "itll buff out" !!!

  • 'Made in China'

  • OK, I wouldn't normally comment on a video but how can anyone think this is due to lift force? The tethers aren't taut :P You'd have to be a complete fool to think this.

  • That should buff right out. lol

  • all filler and no killa........

  • This is not due to upwards thrust but due to ground resonance.This can happen in fully articulated multi-bladed helicopters,

    when the helicopter is running while sitting on the ground even when the helicopter is not strapped.

  • You are very right ! ground resonance

  • Wasnt this a test to see how it would respond without the dampers installed?

  • the beast want to fly !

  • It was made by GM (mark of excellence)

  • That's one hell of an ugly helicopter. Looks like an insect.

  • I dont understand what happend to it? why did it break apart?

  • Google for resonance ;) That's why sometimes even bridges fall apart.

  • resonance, google it, it happend to the bridge in california that colapesed some concept

  • Don't you just love it when two people respond with the same answer?

    I think It fell apart because it was Monday, Google Monday.

  • LMAO!

  • Over stressed. Same thing happens when you cut a square piece out of a coke can, and keep bending it until it snaps.

    Well, same general idea anyway.

  • The rotors are providing massive upwards thrust, while the helicopter is strapped to the ground. Given enough force, the rotor will literally rip itself off of the main chassis of the helicopter, as happened here.

  • looks like it had to use the washroom badly, but since it was tied down, it unfortunately let it all out in the end ='[

  • I lol'd

  • what a waste of i think 10.8mil?

    oh well i bet the guys in charge pissed there pants.

  • Your an idiot shadow.

  • It was in response to the fact that the guy said "what a waste of i think 10.8mil". It's a replica to demonstrate what would happen in a situation where the heli was perhaps accidentaly tethered to the ground. It isnt a proper chinook and definately not worth the amount the guy said it was. And of course the rotors aren't made of carboard, if thats what you were calling me an idiot about.

  • Ground resonance testing.

  • Err...isn't that just a model?

  • Yes, and nobody here realises it.

  • lmao it got its ass blown off

  • Once the thing started yawing side to side like it did it was a dead duck

  • probably he best way to piss well over $1,000,000 or more up the wall

  • aahahaha

  • no skids to disapate the vibrations.

    harmonic amplication to self distruction.

    was this an unexpected outcome?

  • lol thats what happens when you tie it down??

  • The Chinook has proved to be one of the best heavy lifting dual rotor helicopters ever made. Care to mention another one that is better?

  • the rotors had a meeting!

  • No, it's made in Mexico.:]

  • Must be made in China or Taiwan. Good Build Quality.

  • didn't take much to tear the tail off

  • Whoah! What made it cavitate like that? Didn't look like it was running at full power.
