Objectives of the Course The aim of this course is to enable students to reach the competence to perform workshop-level applications by teaching the basic working principles, parts, maintenance and repair processes, safety procedures and relevant terminology of the gas turbine engine systems (turbofan, turboprop and turboshaft) used in aircraft.
Course Content This course covers the definition and classification of gas turbine engines, basic thermodynamic calculations, engine performance, recognition of the turbofan, turboprop and turboshaft sections, system controls, maintenance applications, APU systems, propeller control, reduction gearbox, fault diagnosis, workshop safety, and hands-on disassembly–assembly operations.
Course Methods and Techniques Lecture (direct instruction), question-answer, discussion, practice, and design techniques are used.
