Learning goals:

The student must be able to:

  1. 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)

  2. 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)

  3. Calculate power, torque from brake mean effective pressure and engine dimensions for diesel engines

  4. 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)

  5. 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

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

  7. Explain and describe transmission systems, their components

  8. Make a shafting system strength and vibration analysis

  9. Explain reasons for application of controllable pitch propellers, understand construction of cpp

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