Detailed Description

Base class for all engines.

This base class contains methods and members common to all engines, such as logic to drain fuel from the appropriate tank, etc.

Configuration File Format:

<engine file="{string}">
    <feed> {integer} </feed>
    ... optional more feed tank index numbers ... 
    <thruster file="{string}">
        <location unit="{IN | M}">
            <x> {number} </x>
            <y> {number} </y>
            <z> {number} </z>
        </location>
        <orient unit="{RAD | DEG}">
            <roll> {number} </roll>
            <pitch> {number} </pitch>
            <yaw> {number} </yaw>
        </orient>
    </thruster>
</engine>

    NOTES:

  Not all thruster types can be matched with a given engine type.  See the class
  documentation for engine and thruster classes.

Member Function Documentation

◆ CalcFuelNeed()

double CalcFuelNeed ( void )

virtual

The fuel need is calculated based on power levels and flow rate for that power level.

It is also turned from a rate into an actual amount (pounds) by multiplying it by the delta T and the rate.

Returns: Total fuel requirement for this engine in pounds.

Reimplemented in FGBrushLessDCMotor, FGPiston, FGRocket, FGTurbine, and FGTurboProp.

Definition at line 93 of file FGEngine.cpp.

  FuelFlowRate = SLFuelFlowMax*PctPower;

◆ Calculate()

virtual void Calculate ( void )

pure virtual

Calculates the thrust of the engine, and other engine functions.
