Learning goals:

The student must be able to:

·           L1 Explain and apply prime mover (diesel engine, gas turbine) characteristics (drive characteristic (power/torque-speed relation), operational envelope, indicator diagram, bmep, torque-bmep, (indicated and effective) efficiency, specific fuel consumption, specific air consumption)

·           L2 Explain prime mover (diesel engine, gas turbine) construction types (2- and 4- stroke, trunk piston, cross head construction for diesel engines; gasgenerator, free power turbine concept, simple cycle, intercooled regenerative cycle for gasturbines)

·           L3 Calculate power, torque from brake mean effective pressure and engine dimensions for diesel engines

·           L4 Apply  basic thermodynamics to prime movers (diesel engine, gas turbine) to derive p,V-and T,S-diagrams, to calculate energy flows, fuel/air consumption and efficiencies)

·           L5 Explain and apply ideal models of diesel engine and gas turbine cycles (Otto, Diesel, Seiliger, Brayton), compare with actual process, understand differences with actual engine

·         L6 Explain and describe principles of  pressure charging (exhaust gas driven turbo charging in particular) and its influence on overall diesel engine characteristics (bmep; power density with regard to weight and dimensions; torque/power – speed relation)

·           L7 Explain and describe transmission systems, their components

·           L8 Explain reasons for application of controllable pitch propellers, understand construction of cpp

·           L9 Derive propulsor load characteristics (power/torque-speed relation) based on ship resistance characteristics

·           L10 Apply, understand and explain matching of prime mover to propulsor, as well as the influence of operational conditions on ship’s speed, propeller speed and engine loading

·           L11 Describe and explain main and secondary electric power supplies (DC, AC, frequency)
