So, adding fuel from a low power setting, temperatures spike as you add fuel at low turbine rpm, and cool as the turbine spins up. The turbine feels HEAVY to slow-moving air with little dynamic pressure, so the turbine is at first sluggish, slow to spin up!īut as the speed picks up and the airflow with it, the turbine seems comparatively lighter compared to the airflow moving through it and responds much more quickly! The turbine is slow to respond at low power settings, since not enough air is racing through to rapidly change the turbine speed.

That engine is all about having enough AIRFLOW moving through it to balance the FUEL FLOW to keep the temperatures under control. Well, the PT-6 engine has a distinct feel to it to operate. but the engine just FEELS right.īut how does an engine FEEL right in a simulator? Not only are the fuel flow and efficiency now correct. I got the RECIP engine performance dialed in when flying recip engine airplanes like the Cirrus SR-22 and Columbia-400, and now I’m dialing in the TURBOPROP performance now that I’m flying a turboprop! Thanks to LOTS OF FLIGHT-test IN N844X, which has a PT6, I am getting that engine just right in X-Plane! So, here is the new stuff done for 11.00 so far in the flight and systems modeling area! Thanks to a few hundred hours of flight experience in my Lancair Evolution so far, I am really improving the flight model in X-Plane in the area of PT-6 engines, electrical, and pressurization systems!Īnd, while in the systems code, I’ve improved a lot of other systems simulations as well, which is always fun.

New flight-modeling stuff done recently for 11.00:
