I want a developer who is quite familiar with simconnect/fsx related programming in order to create a realistic startup sequence for my Alouette III project:
http://www.fsdeveloper.com/forum/threads/alouette-3.431494/
Willing to discuss a decent price for this one job only.
Description/Insight about the project as per member on FSDeveloper: ROY HOLMES
Here is what I have found, well not really, it just confirmed what I know.
In the basic older legacy Bell 206. Starting is done by turning on the fuel cut-off. The thing gets to 100% rotor almost immediately, and settles at about 30% torque. That is the extent of the start procedure.
If you add the turbine tables, introduced in FSXA for the EH-101, to the air file and do nothing to the config file, the start procedure is the same but the engine/rotor lacks stability.
If you add the EH-101 style "Helicopter" and engine entries to the config, you can start each engine separately and it will perform according to the Governor PID settings in the config file. The EH-101 original settings were terrible, it used to have N1 hunting and never seemed to settle down to a steady torque. MS never really finished that helicopter before they published FSXA and then laid off the team.
However, with the engine type as 3, the "throttles" (mixture control) have no effect other than a fuel cut-off. So you can start the engine but it immediately tries to govern the rotor at 100% RPM through torque build up in the Proportional Integral Derivative (PID) controller which is part of the simulator software. The rotor brake can not be toggled to prevent N2 starting to rotate the rotor. Without using something like SimConnect you can not do more than just start each engine which starts the rotors.
If you use the engine as type 5 Turboprop, the mixture control can be leaned at about 10% which will reduce the torque and RPM for taxying and this works to some extent when the helo has turboprop engines, though you seem to need a propellor section in the config file. But, it starts and runs the rotors like a turboprop airplane.
The Robinson model has a clutch. You start up the piston engine, rotors do not turn until you engage the clutch. But I have never got that running with any kind of turbine engine.
So, like every one else who does not use SimConnect or something not "natural" to the sim, you can not have engine start without rotor turning except by blipping the rotor brake and that gives wierd negative torque readings.

PLEASE PM if you need to understand the problem in more detail.
