Propulsion equipment: Difference between revisions

From EVE University Wiki
Afterburners and microwarpdrives: Noted mass increase and cycle times. Expanded size table to cover Mass and Thrust.
Afterburners and microwarpdrives: moved the sentence on undersized ABs down to the formula paragraph. Noted 500MNs on Capitals.

There are certain Tech 2 ships ([[Interceptors]], [[Interdictors]], [[Assault Frigates]], and [[Heavy Assault Cruisers]]) which suffer less from microwarpdrive signature penalties. These ships are able to take advantage of microwarpdrive speeds, and use them to evade enemy fire. Additionally, ships designed by [[Sansha's Nation]] have a unique bonus to Afterburner speed, allowing them to achieve speeds comparable to those of microwarpdrives, but with none of the drive's penalties.

There are different sizes of propulsion modules based on basic ship hull size. Using an undersized afterburner on a larger ship will cause the speed boost to become much smaller.  
There are different sizes of propulsion modules, intended for use on different sizes of ships.
 
General guideline for module sizes:

:''V_max = V_base × ( 1 + V_bonus × ( Thrust / mass ))''
:''V_max = V_base × ( 1 + V_bonus × ( Thrust / mass ))''


In practice, that last thrust/mass term is almost equal to one when using properly sized modules on Frigates, Cruisers, and Battleships; and the ship's new maximum velocity is about equal to its base velocity multiplied by the bonus of the propulsion module. However, certain exceptionally light-weight ships (like many Triglavian ships) can achieve higher speed bonuses; and heavier-weight ships like Destroyers and Battlecruisers will receive lower speed bonuses than their prop modules would state.

However, certain exceptionally light-weight ships (like many Triglavian ships) can achieve higher speed bonuses; and heavier-weight ships like Destroyers and Battlecruisers will receive lower speed bonuses than their prop modules would state. Also as a result of this formula, using an undersized afterburner on a larger ship will provide only a very small speed boost. In general, the only time this is ever done is in the act of fitting a battleship-sized 500MN microwarpdrive to a capital ship, as a sort of maneuvering thruster used in single cycles improve alignment times.
