The PT6-62A turboprop engine, which is the power plant of KT-1, was developed to predict steady-state behaviors using the SIMULINKÂ® for the steady-state performance simulation. The S I M U L I N K model consists of subsystems to represent engine components such as intake, compressor, combustor, compressor turbine, power turbine and exhaust nozzle. Performance parameters calculated using the S I M U L I N K model were compared with the results using the G A S T U R B model for validation. Steady-state performance analysis using the developed SIMULINK model was performed. Performance parameters, such as the mass flow rate, the compressor pressure ratio, the fuel flow rate, the specific fuel consumption ratio and the turbine inlet temperature, were conducted to evaluate the validity of the SIMULINK model in various cases. The first case was the uninstalled condition at various altitudes from sea level to 9144m (30000ft) with fixed M.N.=0. The second case was the installed condition at various altitudes from sea level to 7620m (25000ft) with fixed M.N.=0. The third case was the installed condition at altitudes of 1524m (5000ft) and 3048m (1000ft) and at the M.N.= 0.1, 0.2 and 0.3 in ECS operation.
