Spacecraft turbines can operate in one of two modes: closed- and open-cycle. When travelling through [[astrogation]] or during interlunar transit, the turbine operates in a closed cycle, generating a small amount of electricity while returning the cold propellant gas to the reactor for reheating. When at work in the rings, the turbine operates in an open cycle, generating a large amount of electricity and exhausting the waste gas into space. | Spacecraft turbines can operate in one of two modes: closed- and open-cycle.

The primary power generator of fission-powered vessels is typically a thermal-gas turbine that converts the kinetic energy of reactor-heated propellant into electrical energy. Turbines as they exist in Delta-V rely on similar principles to steam turbines, but are much more advanced in their implementation and execution, using expanding supercritical propellant instead of boiling water.

Turbines that are subject to high temperatures produce more immediate power, but are prone to galling. Galled turbines will produce less power overall at standard reactor temperatures, so it's important to maintain them.
Power generation can be increased or accentuated through the installation of an auxiliary power unit.
