In a companion paper, presented as Part 1 (121(99)3, page 377-383), the objectives, justification, and approach of the small gas turbine engine starting improvement study have been described. Given that the Aerodynamic Turbine Engine Code (ATEC) was used in the study, the Part 1 paper also documented the mathematical models and the numerical methods employed in the simulation. A one dimensional dynamic gas turbine engine model, ATEC, was configured to represent the gas generator of the General Electric CT7-5 and was used to explore improved starting methods. The model indicated that, for ground starting, early ignition provided the greatest improvement in starting followed by a combination of increased bleed and a higher fuel flow. Ground level testing indicated that the most substantial improvement in starting was increased bleed, higher fuel flow, and variable geometry rescheduling to control the operating line location. Model altitude windmill restarts indicate the most effective method of improving restart capability is to reduce required torque (removal of auxiliary power). However, this option was not confirmed due to the inability to implement this change in the test cell. Test results indicate that only reduced start bleed and an increased fuel accelaration schedule will improve windmill starting capabilities. Improved starting was predicted using the simulation; however, the magnitudes of the improvement were underpredicted. The model was considerably more sensitive to configuration changes in inlet guide vane, stator vane, and minimum fuel flow enrichment than the engine test results indicate is appropriate. A successful engine simulation for use in starting studies requires accurate information for each engine component, reflecting component operation across the operating range of interest. It is difficult to calibrate in the windmill/low speed range where little or no information exists. This region is important for starting studies. Additional model calibration will be required to incure the simulation accurately reflects the engine.
