> If those helicopter blades spin 40x faster than a real chopper at sea level air pressure on earth, the turbulence alone would disintegrate the flywheel and blades and destroy the whole thing. So how did they test it?
The obvious method would be a large vacuum chamber, evacuated enough to simulate martian atmospheric pressure.
Your post was sneering at the idea of it being real, and I generally don't click on video links without a clear idea of what they are (because video is a low-information-0er-time, high-emotional-engagement medium, and experience has proven that it's almost never worth doing) and I'm even less likely to do so with the implied content from the rest of your post.
AVR = Augmented Virtual Reality. It's like CGI on steroids, crack, and speed at the same time.
People still have the naivete to trust things because they are on a screen. Preconceived notions cause one to mentally miss or gloss over the great artistry and manipulation in AVR cartoons.
The vid is worth the few minutes. It is a half decent scientific experiment that shows how rocket propulsion really works, and it shows an extra factor left out of the Newton's law argument: Ejective oxidation cannot occur without atmospheric containment pressure. Countless experiments have proven this. Buyer beware what they show you on a screen.
Can't reply to your other post unfortunately, but that's not true about rocket propulsion not working in a vacuum. You just have to mix the fuel with an oxidizer if oxygen isn't available. (EDIT: Or just use a method of propulsion other than combustion, but they are usually not as effective)
