Module Title:Electrical Propulsion
Language of Instruction:English
Credits: 10
NFQ Level:7
Module Delivered In 1 programme(s)
Teaching & Learning Strategies: Teaching will be conducted through lectures, practicals and problem-based learning. The Institute VLE will be used to evaluate the student's understanding of the basic concepts during each section, including using class tests. The practical sessions will be used to support the theory.
Module Aim: To provide students with an understanding of how propulsion systems can implement in the age of "more electric aircraft".
Learning Outcomes
On successful completion of this module the learner should be able to:
LO1 Apply the fundamental principles of electrical power generation, distribution, protection and utilization on board aircraft.
LO2 Use computer based engineering tools to evaluate electronically controlled electrical and electronic propulsion systems for aircraft.
LO3 Perform calculations relating to the peformance of air breathing aerospace propulsion systems.
LO4 Develop knowledge and calculate performance of different stages of propulsion systems.
