OBJECTIVES AND CONTENTS
Objectives of the Course Unit:	This course aims to teach the operating principles, performance analysis, and structures of gas turbine engines. By understanding the components and functions of gas turbine engines, students will grasp the maintenance and repair processes.
Contents of the Course Unit:	This course is designed to provide the basic theoretical background that licensed aircraft maintenance technicians should have about gas turbine engine systems. The content is structured according to the Part-66 Module 15 standard in accordance with the SHT-66 Instruction published by DGCA and EASA Part-145 maintenance practices. In this part of the course, the basic physical concepts, engine types, performance criteria and main structural components that constitute the working principle of gas turbine engines are discussed in general terms. Within the scope of Gas Turbine Engines I course; the relationship of physical quantities such as force, work, power, energy, speed and acceleration to engine operation; structural characteristics of turbojet, turbofan, turboprop and turboshaft engine types; thrust parameters, specific fuel consumption and engine efficiencies affecting engine performance; intake systems and ice protection structures; operating principles of axial and centrifugal compressors and basic characteristics of the combustion zone are explained at technical level. This chapter aims to provide maintenance technicians with a holistic understanding of gas turbine engine systems and the ability to apply this knowledge in maintenance activities. It also provides a solid foundation for the following technical modules.
