| Module Title: | Electrical Propulsion |
|---|
| Language of Instruction: | English |
|---|
| 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. |
