Question:
What sort of tank configuration would supply fuel to the
pumps in a spacecraft at all times even when there are no gravitational or
inertial forces acting, if the supply need only be enough to start and run
the rocket engines for a short time? This tank is not to be part of the
main fuel tank.
In brief the problem is therefore how to get enough fuel to the engines
in order to start them when the fuel is free to float around in the tanks.
Replies:
For a liquid fuel you may be able to use a bladder, which essentially is
like a balloon and always squeezes the fuel.
