Returns

Get the Maximum Thrust Output in Atmosphere

Parameters

runningActive	Set to true if wanting actual thrust from an active vessel in flight
useThrustLimiter	Set to false to ignore thrust limiter setting.

atmTemp	Set to the atmospheric temperature. Default = 310f (temp at KSC on Kerbin)
atmDensity	Set to the atmospheric density. Default = 1.225f PhysicsGlobals.EngineDefaultAtmDensity (sea level on Kerbin) currentMainBody.GetFullTemperature(altitude, atmosphereTemperatureOffset) - pass in for real vessel atmTemp = vessel.atmosphericTemperature part.atmDensity - pass in for real density

Get the Maximum Thrust Output in Vac

Parameters

useThrustLimiter

Set to false to ignore thrust limiter setting.

Returns

Returns a multiplier to fuel flow (and thus thrust). Will only do so if atmChangeFlow is true (in which case flow is modified by atmsopheric density, either linearly or via a curve, that's toggled by useAtmCurve) and/or if useVelCurve is true, in which case it's modified by mach finally, it's clamped to CLAMP so it never quite goes to 0. If neither situation obtains, we just return 1.0.

Returns

fuel flow multiplier

< Get the amount of actual thrust the engines are producing

< calculate heat multiplier, starting at 1.0

< Prevent engines from operating if in high warp. Seems to happen with super low thrust engines, that are below accel detection threshold (Ion Engines)

Sets flameout false and, if the first time, plays FX Hides status line 2.

< Update Connected Resources first, or they'll be off a frame on the guages

< Update the propellant guages after the connected resources

< This yields F-1 like curves where F-1 responserate is about 1.

By default allow restart.

By default allow shutdown.

Atmospheric density will change fuel flow (and thus thrust)

Normally thrust is proportional to density, but we allow tuning. Tuning is especially needed because there's no stratosphere, so temperature keeps decreasing and thus speed of sound keeps decreasing.

Same as atmCurve, but changes Isp not flow

a curve to determine loss or gain of thrust due to changes in atmosphere vs vacuum values are based on ISP to ATM Pressure

tunable clamp. The flow multiplier will never go below this.

do we clamp the return percent to the min ratio (and never request more on followups) or do we request all always, and average?

Temp and module values.

When the flow multiplier goes below this, we "flameout" the engine. NOTE: THIS FIXES ASYMMETRIC FLAMEOUTS.

cap beyond which increases to flow multiplier aren't fully felt (start to taper off)

Sharpness of the tapering off of flow increase beyond cap

Used to display fuel flow to the UI Look into better ways of displaying this perhaps.

KSp fields!

Only used/available in the Part Action Window if nonThrustMotor is true. Set to true will include this motor in the Delta-v calcs.

Should the main throttle be overridable by an axis

If the throttle is overrideable, this is the throttle control

heat multiplier for "over-mach" heat

Thermal limit, in Mach, for the engine. Defaults to VERYHIGH. This is not when the engine blows up, but merely when it starts generating more heat than 'usual'.

What is the density of the mixture.

Multiplier to final flow as calculated

Multiplier to final Isp as calculated

set true to tag this motor as one that can be excluded from delta-V calculations. use for things like separation motors that aren't used for thrusting the rocket

Do we divide the heat produced by the flow multiplier to get the final flux? I.e. do we always produce the same heat for the same throttle setting?

How much of our requirement was met. Starts hidden, shown on activate.

Modifies Isp based on throttle. time is throttle, value is multiplier to Isp

tracking fields for it (default non-displaying)

Modifies Isp based on throttle. time is pressure in atm, value is how much throttling affects Isp (i.e. Isp = input * Lerp(1, throttleIspCurve, throttleIspCurveAtmStrength)

Thrust Vector.

The curve to use

Gui Fields.

Do we use the atm curve? If not, and atmChangeFlow is true, just use atm linearly.

should we use a thrust curve (based on resource remaining) ?

If false, we don't use the new velCurve.

replacement for the existing module's velocityCurve. Note that its x value is Mach, not m/s velocity. High-bypass turbofans will see thrust decrease steadily from static. Low-bypass turbofans and turbojets will see thrust decrease slightly up to about 0.2 Mach then increase steadily until the limit is reached (both in terms of heat, and incoming compression vs compressor compression). Ramjets have 0 static thrust, and do not light until 0.3 Mach or so, but once lit have steadily increasing thrust until Mach 5, when the incoming air can no longer be slowed to subsonic (combustion must be subsonic for ramjets). Thermal limits also apply, of course. For heat limits, see machLimit, below.

Same as velCurve but changes Isp not flow
