I have been trying to tune the flight dynamics of an aircraft in FSX.

 

It is a turboprop aircraft that must have reverse thrust. The file that I started from did not have reverse thrust that I could see.

 

In the aircraft.cfg file the following entry was present:

[Propeller]

prop_reverse_available  = 1

 

I have added the following entry:
[TurbineEngineData]
reverser_available     = 1

 

The desired effect is almost complete. The aircraft does stop after I have cut the fuel (F1) and applied reverse thrust (F2), and this help, but not fast enough. Is there a setting where I can increase the reverse thrust or increase the fraction reverse thrust is of normal forward thrust?

As far as I know the reverse should be proportional to the power of the engine and a max reverse thrust scalar as to how effective the reverse thrust is.

 

something like this under General Engine Data:

min_throttle_limit = -0.4                       //Minimum percent throttle.  Generally negative for turbine reverser

 

this should have an effect as to the reverse thrust.

 

 

there are more options you can edit such as propeller, turbine engine data, and turboprop engine sections that will also yield a different result, its all about the culmination of all those parameters that will effect both forward and reverse thrust.

Thaks, I will give it a try. Normally if you are stationary and you apply full reverse the aircraft is suppose to taxi slowly bakwards. My above mentioned setting does not do that yet. It only stops the aircraft, but still not fast enough.

In [propeller] section try setting minimum_reverse_beta to a negative value as well as prop_reverse_available = 1.

 

The default Beech King Air 350 has minimum_reverse_beta = -14.0

 

Incidentally, does the aircraft you are modelling actually have thrust reversal as as opposed to propeller reversal?

It is a Turboprop so it must be similar than the Kingair.

You misunderstand The Kingair gets its reverse thrust from the propeller - not by changing the direction of the jet exhaust. That was what you were attempting by setting reverser_available = 1. It won't have a reverser available
