The Reaction Control System (RCS) provides minor adjustments to course when holding position, orbiting planets and when entering / leaving spacedocks and ports. It also is used to make rapid course changes during emergency / evasive manuvers. Thrusters can provide (or assist) Impulse Thrust in the event normal Impulse Engines are damaged, however given their smaller size the vessel would not be capable of reaching the same velocity as normal Impulse.

Each RCS engine consists of a gas-fusion reaction chamber, a magneto-hydrodynamic (MHD) energy field trap, and upper and lower vectored-thrust exhaust nozzles.

Deuterium fuel for each fusion chamber is stored in six immediate-use supply tanks and tied to replenish lines from the main deuterium tank group in the Battle Section. Fuel transfer is managed by three redundant sets of magnetic peristaltic pumps, pressure regulators, and distribution nodes.

Ignition energy for the reaction chamber is provided by a step-up plasma compression generator, and supplied through a standard capacitance tap by the ship's power distribution net. The reaction chamber measures 3.1 meters in diameter and is constructed of Hafnium carbide 0.2 meters thick, with a 0.21cm replaceable inner wall of duranium tritanide. It can withstand a total of 40,000 firings and 5,500 hours operating time before requiring inner wall servicing. (Credit: TNG Technical Manual)

RCS arrays large "main" arrays for direct thrust, and smaller "auxiliary" arrays for smaller adjustments.

  • A 'newton' (abbreviated N) is the amout of force required to accelerate 1 KG at a rate of 1 meter / second / second.
