In Star Trek, the impulse drive is the method of propulsion that starships and other spacecraft use when they are travelling below the speed of light. Typically powered by nuclear fusion reactions, impulse engines let ships travel intrastellar distances readily. For example, Starfleet Academy cadets use impulse engines flying to Saturn and back. Star Trek collectively refers to a science-fiction franchise spanning six unique television series, 726 episodes and ten feature films in addition to hundreds of novels, computer and video games, fan stories and other works of fiction all set within the same fictional universe created by Gene Roddenberry in the...

There are three practical challenges surrounding impulse drive design: acceleration, time dilation and energy conservation. In the show, inertial dampeners compensate for acceleration. Time dilation would become noticeable at appreciable fractions of the speed of light. Regarding energy conservation, the television series and books offer two explanations: Acceleration is the time rate of change of velocity, and at any point on a v-t graph, it is given by the slope of the tangent to that point In physics, acceleration (symbol: a) is defined as the rate of change (or time derivative) of velocity. ...

Inertial compensators, or inertial dampers (as they are more often called) are fictional devices aboard starships in some science fiction series, including Star Wars, Star Trek, Stargate SG-1 and Stargate Atlantis. ...
- A less-common yet more plausible explanation calls for a gravitational distortion, a wave, through space, which the ship essentially rides. As such, "one half impulse" and "full impulse" measure speed and not acceleration.
Some Star Trek fans claim that impulse drives are actually ion propulsion drives. 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. ...

- Star Trek: The Next Generation Technical Manual indicates that the Impulse engines are Nuclear Fusion engines whereas the plasma from the fusion reactor powers a massive magnetic coil to propel the ship. It is a form of Magnetoplasmadynamic thruster. This is used in conjunction with the ship's warp drive's alteration of the ships relativistic mass, to achieve mid to high sub-light speeds. Thrusters, on the other hand, are closer to the designs of a high efficiency reactant propellant (i.e. a sophisticated rocket engine) and are usually used for high precision maneuvers. Ion propulsion drives are explicitly detailed to be used in Star Trek by Dominion and Iconian Starships and facilities.
- Since a ship travelling at impulse velocities (slower than, but approaching, the speed of light) is still travelling in the normal space-time continuum, concerns of time dilation apply, so high relativistic speeds are avoided unless absolutely necessary; impulse power is therefore customarily limited to a maximum of 1/4 lightspeed. (Warp travel, on the other hand, does not involve time dilation effects.)
Ion propulsion engines use electricity to ionise fuel like mercury or xenon and propel it with a high electric field to generate a low but continuous thrust. Magneto-Plasmadynamic (MPD) thrusters are a form of electric Propulsion which use the Lorentz force (a force exerted on charged particles by magnetic and electrical fields in combination) to generate thrust. ...
