| DESCRIPTION | This study unit discusses the design and operation of the aircraft powerplant. It covers parts of the EASA Part 66 Modules 15 and 17 The study unit provides the following: 1) An introduction of the fundamental concepts and laws governing thermo-fluids. This includes: Potential energy, kinetic energy, Newton's laws of motion, Brayton cycle; The relationship between force, work, power, energy, velocity, acceleration; 2) The application of these fundamental concepts to the gas turbine engine and the role of various engine components. This includes: - The constructional arrangement and operation of turbojet, turbofan, turboshaft, turboprop - The design of the core components of the gas turbine such as the inlet, constructional features and operating principles of the compressor, constructional features and operating principles of the combustor, constructional features and operating principles of the turbine, constructional features and operating principles of the exhaust. 3) The auxiliaries of powerplant installation. This includes: - Auxiliary power units: purpose, operation, protective systems - Configuration of firewalls, cowlings, acoustic panels, engine mounts, anti-vibration mounts, hoses, pipes, feeders, connectors, wiring looms, control cables and rods, lifting points and drains. - Fire protection systems - Engine Monitoring and Ground Operation: Procedures for starting and ground run-up; Interpretation of engine power output and parameters; Trend (including oil analysis, vibration and boroscope) monitoring; Inspection of engine and components to criteria, tolerances and data specified by engine manufacturer; Compressor washing/cleaning; Foreign Object Damage. 4) Propellers: - Fundamentals of propeller theory: Blade element theory; High/low blade angle, reverse angle, angle of attack, rotational speed; Propeller slip; Thrust forces; Torque; Relative airflow on blade angle of attack; Vibration and resonance. - Propeller Construction methods and materials used in wooden, composite and metal propellers; Blade station, blade face, blade shank, blade back and hub assembly; Fixed pitch, controllable pitch, constant speeding propeller; Propeller/spinner installation. - Speed control and pitch change methods, mechanical and electrical/electronic; Feathering and reverse pitch; Overspeed protection. - Propeller Ice Protection: Fluid and electrical de-icing equipment. - Propeller Maintenance: Static and dynamic balancing; Blade tracking; Assessment of blade damage, erosion, corrosion, impact damage, delamination; Propeller treatment/repair schemes; Propeller engine running. - Propeller Storage and Preservation Study-Unit Aims: The aim of this study unit is to introduce aircraft maintenance trainees to the fundamentals of aircraft powerplants.
