Faster Engine rev up.. How ?

Recommended Posts

Hi,I have application where I want the (piston) engine to rev up/down very fast, to the extent that it immediately follows the throttle setting.Any idea which parameter in the .air file or aircraft.cfg file to tweak for that ?Or is it more complex then I think ??Thanks, Rob Barendregt

You could try toying with these - from fs9 baron 58 aircraft.cfg(piston engine)compression_ratio= 8.0 //Compression ratiofuel_metering_type= 0 //0=Fuel Injected, 1=Gravity Carburetor, 2=Aerobatic Carburetormax_rpm_mechanical_efficiency_scalar= 1.0 //Scalar on maximum RPM mechanical efficiencyidle_rpm_mechanical_efficiency_scalar= 1.0 //Scalar on idle RPM mechanical efficiencymax_rpm_friction_scalar= 1.0 //Scalar on maximum RPM frictionidle_rpm_friction_scalar= 1.0 //Scalar on idle RPM friction(propeller)propeller_moi= 6.9 //Propeller moment of inertiapower_absorbed_cf= 0.9 //Coefficient of friction for power absorbed by propellerAlso in the air file ( if set to fuel injection ) section 545 "engine fuel pressure"Happy HolidaysRegards,Roman
