So what I know, is that as the airship rises, air density decreases because of altitude, which means the airship becomes as heavy as the air it displaces, where it won‘t generate any lift.
But what I also know, is that at that point the pressure inside the airship is higher then atmospheric pressure.
Now to my question:
Is the pressure inside the airship the main factor which makes the whole airship heavier compared to the low pressure atmosphere?
And would releasing gas from the airship, to neutralize pressure differences, make the airship lighter again compared to the air it displaces?
Could you gradually adjust the pressure of the lifting gas, so it keeps the same pressure relative to the atmosphere while still retaining its lower density to lift the airship all the way to the edge of the atmosphere, or atleast close to it?
