The overall design of and Advanced Integrated Propulsion System (AIPS), powered by an LV100 gas turbine engine, is presented along with major test accomplishments. AIPS was a demonstrator program that included design, fabrication, and test of an advanced rear drive powerpack for application in a future heavy armored vehicle (54.4 tonnes gross weight). The AIPS design achieved significant improvements in volume, performance, fuel consumption, reliability/durability, weight and signature reduction. Major components of AIPS included the recuperated LV100 turbine engine, a hydrokinetic transmission, final drives, self-cleaning air filtration (SCAF), cooling system, signature reduction systems, electrical and hydraulic components, and control systems with diagnostics/prognostics and maintainability features.

Major Section

This paper begins by first describing the simplistic requirements of a gas turbine engine; how these requirements are best satisfied, frequently with the aid of electronic control systems; what the trade-off between integrity and reliability means; and finally, but forming a major section, this paper describes in qualitative detail a few of the current programmes for Full Authority Digital Engine Controls (FADEC).

Performance Improvements

This paper describes the design and development of a Digital Electronic Control Unit (DECU) that replaces the existing Analog Electronic Control Unit (AECU) on the M1A1 battle tank’s TEXTRON Lycoming AGT1500 gas turbine engine. This program marks the first application of a digital control on a vehicular gas turbine engine. The DECU preserves all functions of the AECU and is interchangeable, while allowing engine performance improvements, such as 20 percent fuel savings at idle. Diagnostic capabilities, using existing control sensors, were added to identify 90 percent of failed Line Replaceable Units. Controls strategies to achieve these results, such as adaptive routines, and some of the illustrative differences between Analog and Digital control implementations encountered in this application, are discussed.
