  7. Abstract:
  8. In this project Sharif Gas Turbine laboratory turbojet engine, and the turboshaft engine which is designed based on the turbojet gas generator are statically and dynamically modeled and required functions for turboshaft control are extracted. In static modeling a repetitive process is applied to reach static operation points. Static operation line and static characteristics of turbojet engine are extracted and compared to relevant sources. In dynamic modeling of turbojet engine a lumped volume is allocated to each component of engine and gas dynamic equations are solved in this volume along with individual performance map of engine components to acquire output characteristics in each time step. Dynamic model performance in constant fuel consumption of the engine is compared to static model result to assure dynamic model performance. In the next stage turboshaft engine dynamic model is produced using the codified method for turbojet engine and dynamic performance of turboshaft engine in power mode is compared to dynamic performance of turbojet engine. In the final phase of the project necessary function for control of turboshaft engine are extracted using Hammerstein-Wiener method
