Improving the Reliability of TF50, TF40, ETF40B FADEC

The successful Naval use of the TF50 and TF40 variants as high horsepower power plants has demonstrated a high degree of utility. Engineering analysis has shown that aspects of their design could be improved to increase reliability and increase platform availability while reducing the cost of ownership. As each year passes, electronic systems that can be housed in the current form factor improve in both reliability and capability. With that in mind, TES have developed a field replaceable, foot print and pin compatible upgrade to the existing FADEC (Full Authority Digital Electronic Control). The upgraded unit has all of the capabilities of the old unit with many enhancements. The enhancements include: full rate diagnostics with user controlled viewers, modular design, removal of maintenance prone components, improved statistical analysis, and the ability to extend data collection. The result of these enhancements will not only improve FADEC reliability but will also allow improved engine prognostics and health monitoring.Copyright © 2012 by ASME
