Pro-Flight has obtained FAA-certification for recurrency flight-training in the Cessna Conquest turboprop, and I have been working rapidly with them over the last few weeks getting X-Plane tweaked to FAA-approval level on the autopilot and engine-management systems. This has resulted in the turboprop engine, electrical, and autopilot systems being completely overhauled, and we have even made the networking a good bit more robust as well (remember, the FAA-certified version of X-Plane actually involves 6 copies of X-Plane networked together) OK, so here is the new engine stuff : - There are now two types of turboprop engines: Free-Turbine and Fixed Shaft. Here is how they work, in reality (and in X-Plane) - The Fixed-Shaft turboprop engine is pretty simple: a turbine spins at insane RPM as fuel is burned in front of it, and that turbine is geared down (a LOT) and a transmission goes right from the turbine to the prop. - This means the prop is hard-locked to the turbine. Whatever percentage of maximum RPM the prop turns, the N1 turns as well. - A perfect lock between prop and turbine. This type of engine is the most efficient since there are no losses in the transmission from the turbine to the prop.
