Knowledge of the working principles of aircraft jet engines, their performances and structure. Competence for applying acquired knowledge in the jet engine maintenance technology.
Having passed the exam, the student will be able to: 1. Define the basic concepts related to the operation of jet engines: thrust, specific fuel consumption, engine rotation speed, rate of engine pressure increase, BPR, EPR etc 2. Explain the working principle and basic characteristics of jet engines, as well as identify similarities and differences of various types of jet engines: turbojet engines, propeller jet engines, turboshaft, turbofan, single-shaft turboprop engines, dual shaft turboprop engines, single-flow jet engines, dual-flow jet engines etc. 3. Calculate the jet engine thrust, specific fuel consumption, propeller jet engine power, degree of thermal efficiency. 4. Explain the working principle, sketch and describe an engine system scheme, e. g. fuel supplying system, lubrication system, engine starting and ignition system etc. 5. Explain parameters for monitoring engine operation and its correctness, and identify basic indications of engine malfunction. 6. Analyse engine storage and shielding. These learning outcomes contribute to the following outcomes of the study programme of aircraft maintenance: - Complete operating manuals based on the analysis of aviation regulations relating to aircraft maintenance, airworthiness and operating requirements. - Classify the levels of maintenance according to the impact on safety and costs of ordinary and extraordinary maintenance. - Distinguish aircraft maintenance according to MSG-2 and MSG-3 concepts. - Distinguish single parts of an aircraft in relation to the physical laws of flying and functioning of aircraft systems. - Apply standard maintenance procedures prescribed in the aircraft maintenance programmes. - Analyse errors in operational flying from the reliability programme in aircraft maintenance.
