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.
In my opinion it's so that everyone adheres the the sci-fi religion, rather than their Creator. Just one lie of many about the heavens to keep people ignorant.
Oh I just googled the ceiling height of helicopters and it said 25000 feet max, and Everest is 29k. Apparently they had some modified helicopter that landed on it, but it had to be done under perfect conditions, and you are asking for a disaster with repeated attempts. But ya, the fake Martian atmosphere would be impossible to fly anything.

All true.

It is impossible to fly anything anywhere that doesn’t exist. You can fly plenty of stuff on devon island ;)
I get it, but it's literally 1/50th the air pressure of the top of Everest. That's pretty damn close to a vacuum. There is no air to displace. I don't think you could blow a feather with a 100mph wind at that pressure.
Devon Island, anyone?
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?

They don’t. It’s astroturfed and retarded.
You should mock people who believe that.
They are fucking stupid and acting as useful idiots.
Shill.
Actually, this isn’t quite right.
Helicopters can (and have) landed on the top of everest, drones have also been flown there.
Space is still fake and gay though.

I really want to go to devon Island and get some selfies with a red filter.

are these African helos or Western European helos?
YUGE asswhole! XD
How stretched is it?? D:

Lol, I think they just flew a drone in northern Canada or greenland and put a red filter on but ya.
You cannot be that fucking stupid.
Can you?
Great point.
