You realize they say the surface of Mars is 50 times less dense than the top of Everest right? And I don't recall any drones (with rotors) flying around on Everest. I don't know why I try, you seem to side with main stream opinion on all issues.
Congrats on admitting that you know absolutely nothing whatsoever that I have ever said. Your inability to comprehend aeronautics is your problem, not mine or the world’s in general.
Go fly a drone on Everest, then. No one is stopping you. You’re not listening and you don’t give a shit about truth. Space is real and you’re a psychopath.
Let's see it on a vacuum chamber on earth. GRanted we have more gravity as the story goes, but my money says it wouldn't be able to take off at 3psi. How does such a light machine achieve that kind of rotation?
Honestly at mars pressure, at mars pressure I don't think it would take off even if the blades went 100 times faster.
Helicopter lift is a well known equation you can play with at home.
Figure out the coefficient of lift, the hardest figure out since it's based on blade design.
Multiply that by surface area, fun fact modern helicopters are so heavy the flexible blade bends into a downward cone, losing up to 5% of it's surface area.
Multiply that by one half of air density. This is also what creates a flight ceiling, and low moisture and tempatures actually improve air density.
Finally multiple that by velocity squared, which is the largest variable used for helicopter flight.
As long as Lift exceeds your weight, you fly upwards. And that's all there is to it.
Something worth noting is how air density is halved, a '100' reduced to '50' isn't a 50% loss but 25%. Likewise velocity is multipled by itself, increasing speed from a '5' to a '7' isn't a two point gain, it's nearly doubled. The blade speed is extremely important.
It's also why those $5 helicopter toys suck. They have one speed, quickly moving high into the air from the higher lift generated while taking off. Their upwards speed actually pushes them higher than than they should go so they start to fall back down, zig zagging up and down (often crashing) because they don't softly adjust their speed like pilots have to. It's a lot like taking a ball and holding it down in a pool, letting it go makes it shoot clear out of the water and then it falls back in and bobs for a bit. For thirty bucks you can get a super basic cheap helicopter toy that lets you control velocity, allowing you to control the fourth part of the equation and achieve smoother flights.
Then you can work on moving up to larger, more expensive, drones as you start to grasp the basics of flight. It's how most people are learning about helicopters these days.
The helicopter is 4 pounds. The rotors move at 2600 RPM and the tips hit Mach 0.7. Mars is also only .38g. It works out.
Neat, so you refuse to say the Sun exists?
Thanks; you’ve outed yourself better than I ever could.
The sun in it's form that has been shoved down our throats since birth doesn't exist.
It's more likely a localized light source within out "atmosphere. Not a gorillian miles away.

I bet you they tested it there, yeah.
You realize hard drives can spin at 15,000 RPM, right?
