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:	The course begins with the fundamental operating principles of gas turbine engines (energy conversion, the Brayton cycle) and the structural characteristics of different engine types. Engine performance, power and speed relationships, efficiency parameters, and environmental impacts are addressed. The functions of components such as compressors, combustion chambers, intake systems, and other engine parts are examined. Additionally, the phenomena of "stall" and "surge" in compressors and their effects on engine operating conditions and efficiency are detailed.

KEY LEARNING OUTCOMES OF THE COURSE UNIT (On successful completion of this course unit, students/learners will or will be able to)
Explains the basic operating principles of gas turbine engines; evaluates the relationship between potential energy, kinetic energy, Newton’s laws of motion, and the Brayton cycle.
Analyzes the relationship between engine power, force, work, energy, speed, and acceleration; determines their impact on the design and performance of gas turbine engines.
Compares the structural characteristics of turbojet, turbofan, turboshaft, and turboprop engines; examines the operating principles of each engine type and analyzes their differences in industrial applications.
Defines the performance parameters of gas turbine engines; evaluates the impact of key metrics such as gross thrust, net thrust, converging nozzle thrust, thrust distribution, and specific fuel consumption (SFC) on engine performance.
