Constructor & Destructor Documentation

◆ Fadec()

Fadec::Fadec ( Bus *  prmBus,

int  prmAxis,

◆ ConnectComponent()

void Fadec::ConnectComponent ( std::string  name,
std::string  guid 
)

we aren't doing anything with the GetFloatPtr yet... it should signify if it is powered or not!

not sure how to handle program delay but it can jack with the numbers

bird injestion test

I think it is easiest for the selected side to just have control these are the request values which will show on the instrumentation
























special case, the X-55 throttle always starts at 0.5 until you move it... and the first frame always gets 0.0 for some reason

http://stackoverflow.com/questions/12943420/c-winapi-removing-a-flag-from-a-dword-bitwise-operator

engine starter

at 0% it is 100%, at 50% or higher it is 0%, non-linear?

should be about 7 seconds to 20%

igniters on

igniters off

what to do with igniters? continuous ignition?

compression break compression ratio between front and back, inside combustion vs. bypass?















energy transfer between N1 and N2

windmill test

rolling friction

air friction

What can cause flameout? too much water? too much air for too little FF? Too cool of ITT?

have to redo this... it would interrupt a normal start by cutting fuel flow at 120 degrees!

meter TLA flow based on N2?

could check that the ignitor wasn't on?

I have FCOM questions regarding CRJ200 ignitors - A and B are both high tension? or is one low tension? continuous runs both A and B but we alternate A or B each start!

see if ignitor lights it by random

combustion drives both shafts

Diffuser

  • N1 has actual rotation (setState) and sensor (currentState)?
  • N1 sensor is attached to N1 and relays the speed
  • N2 has actual rotation and temperature
  • N2 sensor is attached to N2 and relays the speed ITT sensor is attached to N2 and relays the temp
  • starter is connected to N2 Jet pipe afterburner? (uses a lot more fuel) EGT sensor? AVM (vibe, usually two per engine, higher of the two readings) Reverser/VTOL deflection/redirection reverser door, vtol duct, servo



    so starters, need components for those and we get pointers eventually we will have dependency on fuel line which is dependant on fuel pump and fuel in reservoir


    relative wind from the front (based on how far open it is) adds to pressure that we can create based on density 20% of the power is from the combustion, 80% is from the air N1 and N2 are not physically connected N2 is at 60 and N1 is at 25 at idle at SLP? 7% N2 we get ignition, 20% N2 we get fuel flow... if no light in 5 seconds we abort 50% N2 ignition off, starter cutout

    two buttons at front of unit could be reversers... only work on ground ATTCS handles TOGA is automatic N1 differential of 15%, windshear, or thrust levers past 100% stop (must be in idle) start (initiate start sequence, alternates fadec channels each start), run... ignition -off disregarded WOW, auto (fadec controlled), ovrd (continuous when engine is in RUN mode)
    air inlet temp T2 for fadec,
