Maneuvering with Reaction Control System (RCS) Thrusters

Contents

Reaction Control System

Background of RCS

Depending on the starship type, the system consists of a number of thrusters mostly located at the edge of the saucer hull (generic).

Thrusters (aka: Maneuvering thrusters) are used by starships and other spacecraft to make precise movements at very slow speeds in lieu of primary impulse or warp engine use. Thrusters are low-power reaction control jets that may be used for fine positional and attitudinal control, including station-keeping. They are typically used in docking maneuvers.

Thruster systems rely on Newton's Third Law which states: "Every action must have an equal and opposite reaction."

Positively and negatively charged particles are separated. Using a set of magnetic fields, these particles are accelerated to the direction opposite the direction the vessel or other body is trying to reach. Due to the impulse of these particles as they're expelled, a force acts on the body in the opposite direction, equal to the force with which the particles are expelled. As a result, the body is accelerated in this direction.

RCS Thruster Maneuvering

  • Find several graphics of Cubes using 3 vectors/axes (X Y & Z).
  • Upload graphics of Mutara Nebula (Kirk v Khan) maneuvering.

X = Straight Forward & backward; Y = Port & Starboard; Z = Straight Up & Down


To Move:

  • Forward - all Aft Facing Thrusters would activate
  • Reverse - all Fore Facing Thrusters would activate


  • Side Slip to Port - All Starboard Thrusters would activate
  • Side Slip to Starboard - All Port Thrusters would activate


  • Straight Up - All Ventral Thrusters would activate
  • Straight Down - All Dorsal Thrusters would activate


  • To Pivot Left - Fore Starboard & Aft Port Thrusters would activate.
  • To Pivot Right - Fore Port & Aft Starboard Thrusters would activate.


  • To Roll Left - Dorsal Port & Ventral Starboard Thrusters would activate.
  • To Roll Right - Dorsal Starboard & Ventral Port Thrusters would activate.

The Mutara Nebula Incident

Mutara1.jpg
Phenomena like the Mutara Nebula decrease the ability of a spaceship to utilize sensors.

Mutara2.jpg Mutara3.jpg
Kirk orders the Enterprise into the Nebula, where he can even the odds against a "Superior" opponent.
Mutara4.jpg Mutara5.jpg
The Enterprise was able to spot Reliant and get off a few quick disabling shots. Reliant tried to fire torpedoes, but could not lock onto Enterprise, which had already changed course.
Mutara6.jpg Nebula7.jpg
When Spock realizes that Khan is using 2 Dimentional tactics & strategy, Kirk orders a course of "Z -10000 Meters, allowing Reliant to pass overhead. Kirk then orders a return to original course to arise behind the Reliant and

fires, completely disabling Reliant.
