Assessment Description: * indicates an assessment task which must be repeated if a student misses it due to special consideration

Propeller Assignment: This assignment on Propellers will be in a Report form and includes the results of the lab and the propeller performance calculations.

Gas Turbine Assignment 1 : Gas turbine engine cycle calculation: selection and design.

Gas Turbine Assignment 2 : Gas turbine off-design performance

Quiz 1 and 2: Exercise to be solved independently during the tutorial and handed in (Open Book)

Tutorial Exercises: Solution of one tutorial question per tutorial as specified by the unit coordinator at the end of the tutorial

Gas Turbine Lab Report: Report on the lab on the micro turbine including performance calculations and operating line. Due 1 week after the actual lab. Lab runs in multiple weeks. Students will be assigned a specific session.

Final Exam: The exam consists of 2 parts:

Part A Exercises: The student takes a two hours examination at the end of the course. This is worth 15% of the total marks. This part of the exam is open book and written.

Part B Theory: The student has an oral exam on the theory of the UoS. Each student will prepare and answer 2 questions and discuss/explain the answer to the UoS Coordinator.

You must get 50% in the final exam to pass the unit, regardless of the sum of your individual marks.

There may be statistically defensible moderation when combining the marks from each component to ensure consistency of marking between markers, and alignment of final grades with unit outcomes.

The penalty for lateness is 5% per day.
