Post Jet engine thrust control
on: July 4, 2012, 10:24

Hi

Well i finally have P3D so i can develop my projects at Milviz for it as well now :D .

So i ran into a bit of a problem....I need to be able to control the net thrust of turbine engines directly. I have my own physics engine planned which will simulate all the thermodynamics involved in order to not only get proper performance at both low and high altitude but also to simulate variable area jet nozzles. However the variable is not settable in Simconnect neither in FSX or P3D and i need to be able to control it for both. Is there any other path that can be taken outside of the SDK?

Thanks

Hi Jonathan,

Setting the nozzle directly is not supported when using our internal airplane implementation. It is tunable as a function of N1 and Mach within the .air file (See JetSample.asm for an example).

If you are using your own "physics engine" for the aircraft simulation using the SimConnect ExternalSim interface, you can set any simvar in order to have them available for other systems, animations, etc... We do not really support external simulation of just a portion of an aircraft's physical simulation, such as plugging your turbine engine model into our aircraft simulation.

I hope this helps.

Not quite...I dont want to control the nozzle, I want to control the thrust of the engine directly. Also i need to do it for both FSX and P3D. This is going a little bit beyond the limitations of simconnect. Sort of a hybrid system....Doing a full on physics engine is rather overkill for my projects and also requires more data on the aircraft than i what i can get hold of.
