	Encyclopedia: Impulse drive (Site not responding. Last check: 2007-10-09)
		Impulse engines may also be a type of nuclear pulse system such as suggested for the real-life projects A Redstone rocket, part of the Mercury program A rocket is a vehicle, missile or aircraft which obtains thrust by the reaction to the ejection of fast moving exhaust gas from within a rocket engine.
		On Constitution-class starships the impulse engines were on the aft edge of the saucer section; on later Galaxy-class starships the main impulse engine is actually four grouped engines located on the aft of deck 23 of the engineering hull.
		Impulse engines may be used to propel the ship and as a power source at the same time; they can also be used to maneuver a ship and keep it aloft in planetary atmospheres, even if it does not have an aerodynamic shape.

	TrekWars - The Furry Conflict: Impulse Drive Propulsion
		Although the design specifics of impulse engines may vary from culture to culture, there are four primary components that remain essentially the same through all of them: fuel storage, reactors, the space-time driver coils (cochrane coils), and the exhaust assembly.
		Notwithstanding the fact that all of these components are critical to operation of an impulse drive unit, the space-time driver coils, or cochrane coils are what allows vessels to achieve speeds and accelerations that would have otherwise been fuel prohibitive by Newtonian thrust-based systems such as ion drives.
		In theory, this property of impulse drives could be used to propel a ship as fast as.99c, but because it is a sublight drive, ships operating under impulse power are still subject to the rules of relativity, meaning issues with time dilation can become a serious factor.

		An impulse applied to a body causes its momentum to change and is equal to that change in momentum.
		A stimulus from the environment may cause impulses to be sent from the receptor receiving the stimulus, along a sensory neurone, and to the brain or spinal cord.
		A nerve impulse is an area of a neurone which has an altered electrical potential, commonly described as an area of depolarization.

	Starship Drives
		Impulse drive is the standard motive system for slower-than-light manoeuvering for all star vehicles.
		Using simple hydrogen isotopes, impulse drives maintain a "hot fusion" reaction, similar to the fusion reaction in stars, that provides the energy needed to accelerate a spacecraft across interplanetary distances.
		The ramscoop section of the impulse drive is also composed of electromagnetic field generators -- on small ships, these are in fact the same generators as those used for the engine section.

	Impulse Drive
		The Impulse drive is a propulsion system that works on the classical Newtonian reaction principle and is used for subphotonic flight.
		The field conductors accelerate the particles to the speed of light, until the particles are forced to leave the spaceship through the field nozzles.
		The Impulse drive technology allows acceleration values in the order of 700 km/s2 and maximum velocities close to the speed of light.

	impulse drive
		The standard Impulse fusion reactor as used in the Galaxy class Starship is a sphere six meters in diameter, constructed of dispersion-strengthened hafnium excelinide.
		Actual Impulse flight performance is therefore dependent not only on the specifications of the fusion reactors, but also on the capabilities of the driver coils.
		In theory, the coil alone could be used to drive the ship by simply adjusting the mass so that the velocity reaches the desired level.

		Any ship with Impulse Drives can apply as much of their free thrust-up to the total-through their impulse drives to perform any maneuver they so choose.
		Note however that, unlike ships utilizing bio-drives, ships with Impulse Drives may purchase additional thrust and over-thrust their thrusters, though this requires a critical check just as is used for standard thrusters that over-thrust.
		Impulse thrusters are not applicable targets for called shots should the called shots optional rule be in play.

	Defiant Power Allocation
		The warp drive, shields, phaser arrays, and cloak are built directly into the warp nacelles, and derive power directly from plasma generated in the matter-antimatter driven warp core.
		As impulse and warp drives are not used at the same time, the swap group is normally connected to whichever power source is not being used for propulsion.
		Fusion should be used to drive the swap group when under high speed warp drive, to reduce the load on the warp system.

		Possibly warp drive was even known as soon as the schism between Vulcans and Romulans occurred 2000 years ago.
		The "simple impulse power" statement by Scotty can be interpreted in that the ship has an impulse (=fusion) reactor as a power source, which would have nothing to do with the type of its engines.
		This ship had warp drive which was necessary to reach the Neutral Zone, but could not use it while cloaked because of the enormous power consumption of the cloaking device.

	Station Information - Impulse drive
		In the science fiction (like the Star Wars and Star Trek universes), the impulse drive is the sub-light speed engine that the starships use when they are not travelling at warp speed or in hyperspace.
		According to the show, "full impulse" is light speed (300 thousand kilometres per second) so half impulse would be 150 thousand km/s.
		Let's assume the Enterprise was at a standstill to begin with, and that it took fifteen seconds to reach half-impulse speed.

	Star Trek: Federation Propulsion Technology
		There is some debate as to whether Federation impulse drives must accelerate a starship in conventional space physics fashion, as opposed to simply initiating the space warpage that allows them to reach high relativistic speeds and bypassing the normal acceleration curve requirements.
		Impulse fighters can easily outmaneuver capital ships (as seen in "Sacrifice of Angels"), so this allows us to determine that capital ship acceleration is between 10 km/s² and 15 km/s².
		It is possible that impulse drive doesn't allow sufficiently fast direction changes to be used alone in combat maneuvers.

	Impulse drive
		In the show, the impulse drive is the usual propulsion system used for sub-light-speed movement and orbital or docking manoeuvers.
		Such a drive would provide a purely electrical propulsion system requiring no reaction mass, i.e.: no propellant of any kind, which would be mostly useful to reduce the weight of space probes.
		Professor James Woodward of California State University Fullerton has acknowledged to be working on one type of impulse drive based on the same principles, for a NASA long range study of promising new technologies.

		Control of the impulse engines is maintained by computer automation and crew command input.
		Each engine has four parts; the impulse reaction chamber, the accelerator/generator, the driver coil, and the vectored exhaust director.
		Because of the nature of the energy released during the fusion process, the impulse propulsion system needs slightly more maintenance than the warp propulsion system, even though warp engines are a million times more energetic than impulse engines.

		One of the stranger facets of Romulan history is the idea that the species did not have warp drive until after their encounter with Kirk in the episode "Balance of Terror".
		Scotty's use of the words 'their power is simple impulse' has been widely misinterpreted and misquoted as 'they have only impulse drive' or 'they do not have warp drive', or some equivalent variant.
		It is certainly within the bounds of possibility that the ship in Balance of Terror had no warp drive, and indeed it is possible that the Romulans as a species had no warp drive until after this episode.
