Normal-space propulsion system.

— In-Game Description

Thrusters are what propels a ship when flying in normal space. Upgraded thrusters can accommodate heavier ships, increase ship speed and improve manoeuvrability. If you go over the Engine Optimal Mass, you will be unable to travel at the top speed of the craft until you lower your mass.

Theory based on player-gathered data Edit

A ship's top speed is based on the ratio of optimal mass of the equipped thrusters to the total mass of the ship. This ratio is only linear in the case of C-rated thrusters. A- & B-rated thrusters are positively concave, meaning that they benefit more from a total mass lower than optimal mass and have less of a disadvantage from a total mass higher than optimal mass. D- & E-rated thrusters have the opposite effect.[1]

At a total mass identical to the optimal mass of the equipped thrusters, a ship's top speed will always be identical to the advertised speed, no matter the rating. This does not mean that a higher rated thrusters won't have a benefit over lower ratings, as they have a higher optimal mass.[1]

Power Distributor rating and class appears to have no effect on top speed (outside of it's mass), but the number of pips allocated to engines do. Top speed per pip allocated is a linear function, meaning that 2 pips will have a speed exactly between 4 pips and 0 pips, but the speed modifier of 0 allocated pips depends on a hidden value belonging to the ship, as can be seen in the table below.[1][2]

Type-9 Heavy 0.305
Type-7 Transporter 0.335
Hauler 0.350
Type-6 Transporter 0.410
Anaconda 0.445
Sidewinder MkI 0.450
Adder 0.455
Asp Explorer 0.480
Cobra MkIII 0.500

Viper MkIII 0.625
Orca 0.665
Imperial Eagle 0.700
Federal Assault Ship 0.710

Imperial Courier 0.785
Fer-de-Lance 0.845
Vulture 0.905

Thruster effect on ship agility in the form of pitch, yaw & roll speed as well as acceleration has yet to be determined.[1]
