As long as there is air to push, you can push it. That's the theoretical limit. | |

| Jul 11, 2014 at 23:16 | comment | added | Floris | Do you consider a jet engine to be a fancy propeller? In other words - is this about "moving the air around you" versus "relying on the thrust of the expelled propellant" (rocket)? A high bypass jet is really a propeller that is driven by a turbine. Can you clarify what you mean? | |

| Jun 14, 2014 at 14:33 | comment | added | Mike Dunlavey | If we extrapolate from the Helios, no matter how thin the air gets, if you can make a subsonic airfoil light enough, it should be able to be propeller driven. There is a limiting issue, which is that the speed of sound decreases with altitude, so a subsonic aircraft might have to travel very slowly (in indicated airspeed, which is not necessarily slow speed over the ground). | |
| Jun 11, 2014 at 20:27 | comment | added | moose | And I would like to know if I got all factors which determine how high a plane can get. | |
| Jun 11, 2014 at 20:25 | comment | added | moose | No, I just said that current prototypes (or rather: the best I found) can fly at least 29,523m high. I want to know if, for example, we had more efficient solar cells / lighter material they could even get to outer space. I guess not. I guess there might be a hight (below 160,000m) that cannot be reached. | |
