A turbofan engine includes a fan, compressor, combustor, high pressure turbine, and low pressure turbine joined in serial flow communication. The high pressure turbine includes two stages of rotor blades to effect corresponding exit swirl in the combustion gases discharged therefrom. A transition duct includes fairings extending between platforms for channeling the combustion gases to the low pressure turbine with corresponding swirl. First stage rotor blades in the low pressure turbine are oriented oppositely to the rotor blades in the high pressure turbine for counterrotation.

A turbine nozzle includes a row of vanes joined to radially outwardly inclined outer and inner bands. Each vane has camber and an acute twist angle for importing swirl in combustion gases discharged at trailing edges thereof. The trailing edges are tilted forwardly from the inner band to the outer band for increasing aerodynamic efficiency.

A method and system for assessing whether adjustment factors used in a process for testing or monitoring an operational system need to be updated or changed, as well as changing and updating these adjustment factors if needed or desired. At least one current adjustment factor is selected, along with the relevant data. The relevant data is then analyzed to generate results that are collected so that a determination can be made as to whether the current adjustment factor(s) needs to be changed. If it is determined that the current adjustment factor(s) needs to be changed, an updated adjustment factor(s) is provided to replace it. Preferably, the updated adjustment factor(s) is validated before incorporating it into the testing or monitoring process.
