Book Description

The report was undertaken to establish cost-effective recommendations for improving the design life and maintainability of Army gas turbine engine fuel control systems. Army experience indicates that problems with the fuel control account for 10 to 13% of the engine malfunctions and that 30 to 50% of the fuel control removals are unjustified. Data collected during the study indicates that failure modes common to the majority of all present-day fuel controls account for about 25% of the control removals. These failure modes included susceptibility to air and fuel contamination, fuel seal leaks, wear of drive splines, and improper adjustments. (Modified author abstract).
