/** Propulsion management class.
|
|
The Propulsion class is the container for the entire propulsion system, which is
|
|
comprised of engines, and tanks. Once the Propulsion class gets the config file,
|
|
it reads in the \<propulsion> section. Then:
|
|
|
|
-# The appropriate engine type instance is created
|
|
-# At least one tank object is created, and is linked to an engine.
|
|
|
|
At Run time each engine's Calculate() method is called.
|
|
|
|
<h3>Configuration File Format:</h3>
|
|
|
|
@code
|
|
<propulsion>
|
|
<engine file="{string}">
|
|
... see FGEngine, FGThruster, and class for engine type ...
|
|
</engine>
|
|
... more engines ...
|
|
<tank type="{FUEL | OXIDIZER}">
|
|
... see FGTank ...
|
|
</tank>
|
|
... more tanks ...
|
|
<dump-rate unit="{LBS/MIN | KG/MIN}"> {number} </dump-rate>
