      I was thinking of that the whole episode long. ANY stable rocket needs a center of mass directk in the line of your thrust vector. That, or incredibly complex stabilization techniques ala SpaceX.
      Just looking at the steel beam on the grill, it's clear the team *tried*, but this is something that really could have used an aerodrome engineer consult.

    Honestly I would've liked to see it fly as far as possible...but it seems it was front heavy or the rockets caused it to torque around its CG-maybe if they laid the rockets horizontally it could've worked but it might've fish-tailed then....still amazing and enjoyable episode, they're a great team.

    Ramp needed to be thicker & it needed a small extension at the front, at a shallower angle, to stop the car bottoming out when it hit the base of the ramp, which made it to bounce up of the ramp & lose traction on the surface & caused it to flip more than fly

    Stacking the rockets vertically means the thrust wasn't inline with the centre of gravity of the car, resultng in asymetric thrust. They should have know this and corrected for it!

    The berm should have been able to resist shear force. Bags laying loose on top of a flat surface doesn't really work. Even then I don't think it would have caused a jump. The problem with the Myth is that it entirely depends on the configuration of the rockets. As you can see in the second test even when it's airborne it still turns downwards, which shows the total force is acting above the center of gravity of the car. If they placed the rockets such that the force acts slightly below the center of gravity they would have easily seen it go very far. If they did some aerodynamic modeling they could have predicted this far better.

    • @81formann

      Exactly. This is one of the episodes that just breaks the whole show. Their knowledge of physics are more than enough to understand something this simple. Even if this wasn´t true, they have actual rocket engineers helping them. This is far from advanced physics. Even a 12yr old would do a better job after playing around with Kerbal Space Program for a couple of hours.
      This is at best lazy and shoddy work. I don´t care about the reasons, I care about misleading and/or false information being spread by people who not only should, but in all likelihood _do_ know better.

      Came here to say the same ;-) That berm was nothing but a few inches of sand vs. one ton of metal at 200mph. I would expect even a berm made of concrete or metal would just have been pushed into the ground instead of bumping the car up. Just too much downward force.
      The problem here is weight more than placement of the rocket. Due to all the precautions and safety, the weight would probably be much higher than at the "original" car (if it even existed). The rockets would probably be fixed to the roof and not inside, which might cave in a bit to the back and give the rocket power an angled upward force that could help it take off on a small (and non-yielding) bump.
      That said, I do not think the myth is real, just because it takes serious work to combine a rocket engine and a car and not just make it shear off all welds or clamps or screws and fly away leaving the car a crispy wreck on the road.

    • @ab_c4429
      @ab_c4429 7 หลายเดือนก่อน +1

      @@rwandaforever6744 If the myth explicitly made clear the rocket was mounted on top of the roof, there is no way it could ever lift off. I don’t find it far fetched to believe someone could have made this by themselves though. It’s the combination of very unlikely things that makes the myth busted. But I’m not very satisfied with the way they bust this myth.

  • @saardean4481

    i think if the ramp had a bit of a flatter angle and was longer it would fly further. The front suspension bottomed out on the ramp if i am not mistaking

    • @grnbrg
      @grnbrg 7 หลายเดือนก่อน +4

      And a stronger deck -- at @47:09 you can see the the front left wheel was pushed through the surface of the ramp. a singe layer of OSB just wasn't enough. And although tumbling was inevitable, this might have induced a forward pitch force that lead to the fact that the car was rotating toward the ground as it left the ramp...
      It's easy to armchair quarterback something like this a decade later, though. Hindsight is 20/20 and all that. :) Still one of the cooler episodes.

    to all those comments about how to rockets were positioned wrong and the thrust wasn't centered: yeah, true for sure but what else they could've done? if you're gonna stack rockets horizontally, then you gotta cut the whole back of the car. you can't put them on the ground, putting to sides would've been even more problematic, so you put them either high above or vertical at the back. in the original jato myth, i suppose they were mounted on the top anyway. so there's like literally no practical way to make a missile out of a car. it's not an aircraft, it's bound by the ground and you can't center the thrust like that
    p.s: i think the first car could've went straight longer if adam didn't lose control. but the second was inherently hopeless and jaime did the best possible job

    For me the center of mass wasn't calculated well enough. But the ramp was not build optimal either. The car lost a lot of speed at the first part of the ramp, and flew from the middle of it. A less steep entrance to a gradual inclining angle would've been a more disirable trajectory. It was quite entertaining never the less.

    They did not line the center of thrust and center of mass properly, ask any Kerbal Space Program player. Center of thrust was higher than the center of mass, pushing the car over. One rocket less on top and it would've flown beautifully.

    • @magnemoe1

  • @Crwydryn-x3r
    @Crwydryn-x3r 7 หลายเดือนก่อน +4

    This is what the Mythbusters were best at: magnificent experiments designed to fail.
    In the myth the rockets were strapped to the roof of the car, closer to the car's center of gravity than rockets at the rear. At high speed the resistance of air against the belly of the car could have pushed the car upwards as the weight of the engine was pulling the nose down, resulting in a good pitch. That could have happened if lift-off had occurred at a very high speed, much higher than in the experiment. Cars of the 1960's were not designed for good aerodynamic behavior. Driven fast enough, they could have lifted off by themselves because of turbulence under the car.

      @adam-kx7du 7 หลายเดือนก่อน +1

      Quite the opposite, the front was too light, so it allowed the rockets to push it down. If it were heavier, it would have had more momentum, and it would have been harder to disrupt said momentum

      @ab_c4429 7 หลายเดือนก่อน +1

      The problem wasn't the distribution of weight on the car (forward backward c.o.g. movement), but rather the height at which the resultant force acts with respect to the vertical c.o.g. In this case it was above, causing it to nose dive. To make a claim about the horizontal c.o.g. you would need to know the aerodynamic center first.

After all the years of car myths, I'm staggered they disn't think about the suspension bottoming out and the HUGE counter weight making contact with the wood. Damn, SO close to getting a decent flight path but still very worth it 🙌
