Functionality and mechanics
Repulsor engines use stacked tidal gravity generators which create asymmetrical gravity fields that push and pull a ship through space in a desired vector, all without the need for reaction mass or conventional exhaust. An extremely sophisticated application of gravitics, these engines are powered by a ship's pinch fusion reactors. Modern repulsor engines are finely tuned and expected to operate for years without maintenance refreshes. However, the repulsor engines on older, vestigial warships—such as the drives outfitted on the Hekar Taa-pattern blockade runner—are cruder pieces of technology, requiring constant monitoring and adjustment to operate at full power.
