Fuel

In order to use thrusters, you will need to create at least one Fuel Tank and Fuel Reservoir.

Fuel Tanks

Fuel tanks are the physical components which comprise Fuel Reservoirs, from which thrusters consume fuel. Fuel Tanks are defined by their fuel mass, tank shape, and priority. The fuel mass includes only propellant, as all dry mass (and inertia) should be included in the Spacecraft Mass properties.

The tank shape is used to dynamically calculate the inertia of the spacecraft as the fuel mass changes. Currently, the fuel is assumed to be uniformly distributed within the tank. Tanks can be spheres or spherocylinders (a cylinder with hemispherical caps).

Assign a priority to each tank, as tanks with higher priority will be drawn from first. Tanks with equal priority will be drawn from simultaneously at equal rates.

Fuel Reservoirs

Fuel Reservoirs are an abstract collection of Fuel Tanks from which thrusters draw. When creating a Fuel Reservoir, select the tanks that comprise it, which are listed in the Fuel Tanks table.
