Abstract
A steady-state performance simulation program using $EASY5^{(R)}$ on the turboprop engine was developed through in this study. The PT6A-62 turboprop engine which is the power plant of the first Korean basic trainer KT-1, was selected for this study. In order to evaluate the proposed perfrmance model the analysis results of $EASY5^{(R)}$ model were compared with the simulated results by the GASTURB program, which is well blown commercially for the simulation performance analysis at various cases. The first case was the uninstalled condition with various altitudes from ground to 30000ft and flight Mach No. 0. The second case was the install condition with various altitude from ground to M at the maximum take off and the ECS (Environmental Control System) OFF conditions. The third case was install condition with the altitude range from 5000 ft to 1000ft and Mach No. 0.1 to 0.3 at maximum ECS operating condition. It was confirm that the results by the $EASY5^{(R)}$ model were well agreed with those by GASTURB within maximum 5.0%
