an internal combustion engine or a conventional nozzle drive does not work on the mars, no oxygen. the small heli had electric drive with rotors; then the composition of the atmosphere does not play a role. with very low density, the rotors have to be only large enough to produce

Slide to Mars? At 1/1000 atmospheric density? It’ll be a “Kracher”…

also not, for that the 200 m long, huge wings should have.

the density of the mars atmosphere is only 0.6% of the earth

how often you have to make it clear that a “starship” on the basis of an aerodynamic aircraft on which mars works just as little as a poppy paper flyer.

have you become so far from reality by science fiction that you want to ignore physical laws?

No. For combustion, jet engines need oxygen from the environment. It’s not in space or Mars.

Because he doesn’t have a combustion drive.

Because these rotors are designed so strongly that they still work in an ultra-thin atmosphere. My tip: Take remedies in physics!

The small heli on Mars mission has an electric motor as a drive. Its battery is charged with solar cells.

At least the one small helicopter who has flew on Mars so far had an electric drive (energy supply without air per battery).

Our commercial helicopters are operated with internal combustion engines that also absorb their oxygen from the environment. Another drive is needed for operation in the Mars atmosphere. This could be, for example, an electric motor, an internal combustion engine with oxygen tank or small rocket drives on the rotor blades.

In the very thin atmosphere on Mars, this would be very complex and uneconomical. To do this, one would need such a gigantic runway and runway that nobody would build there.

Helicopters can.

Remember: It is not only the lack of oxygen in the atmosphere that prevents the use of internal combustion engines.

In addition, the Mars atmosphere is very thin, the "air" pressure on the ground is only a 100th of a bar – on earth at 35km altitude.

In order to be able to lift off, an aircraft on Mars needs 10 times the speed on Earth and a correspondingly long runway. They don't exist on Mars.

No.

Jet engines require an atmosphere with oxygen.

Mars didn’t. The Mars atmosphere consists of 96% carbon dioxide.

No even afterburners need air
