Ignition system. Exhaust and cooling system. Lubricants and fuels. Lubricating system. Monitoring engine parameters and work on the ground. Inspection of engine and its components according to the criteria set by the manufacturer. Engine storage and shielding. Engine conservation and deconservation, its components and systems. Fundamentals of propeller theory. Propeller construction. Control of propeller pitch. Propeller systems (synchronisers and synchrophasors, anti-icing and deicing systems etc.). Propeller maintenance, storage and conservation.


Knowledge of the working principles of aircraft piston engines, their performances and structure. Competence for applying acquired knowledge in the piston engine maintenance technology.

Learning outcomes:

Having passed the exam, the student will be able to: 1. Define basic concepts related to the operation of piston engines: power, torque, specific fuel consumption, engine rotation speed, compression ratio, working capacity, compression volume, octane rating, mixture richness, degree of thermal efficiency. 2. Explain the working principle, identify the difference between the ideal and real cycles, and define mechanical losses in an engine. 3. Describe main engine parts, and connect them into assemblies, e.g. engine mechanism, distributor mechanism etc. 4. Analyse working principles, sketch and explain the engine system scheme, e. g. fuel system, exhaust and cooling system, lubrication system. 5. Explain the propeller structure and systems, define the control of propeller pitch, analyse the methods for propeller maintenance, storage and conservation. 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.
