Written tasks have been set requiring learners to describe the principles of jet propulsion and the purpose of three sections of a gas turbine engine, covering (P1 and P3). A sketch is also required to show the working cycle of a gas turbine engine (P2) and this task could be extended to meet M1, which is to explain the working cycle of a gas turbine engine. The assignment should be written in a concise, formal business style using single spacing and font size 12. You are required to make use of headings, paragraphs and subsections as appropriate and all work must be supported with research and referenced using a standard referencing system. Provide a bibliography using a standard referencing system. Principles of Gas Turbine Propulsion 1. Know the basic principles of gas turbine propulsion.

Sonntag R and Bourgnakke C – Introduction to Engineering Thermodynamics (John Wiley and Sons, 2006) ISBN 0471737593 for Engineering Technologists Assignment Brief and Guidance: Scenario: An understanding of the construction and operating principles of aircraft gas turbine engines and knowledge of different types of aircraft turbine engine, their function, construction and installation arrangements, are fundamental requirements for those wishing to practice as aircraft engine technicians or engineers, irrespective of their chosen specialization. Consider yourself as an apprentice and you are about to finish your apprenticeship program in a large aircraft engine manufacturing company. Your line manager has asked you to produce an information leaflet detailing the underpinning principles of engine operation. To do this, it is vital that you should have a sound knowledge and understanding regarding the fundamental principles of turbine engine operation and performance, and about the purpose of different sections of a gas turbine engine. To comprehend your knowledge and understanding, your manager has set a series of tasks for you to complete. Accomplish and submit your answer using an appropriate report format and referencing. Prepared by Nakibul Hussain Nuhash Ref-Ver: 1.0, 30/09/2020 Page 2 of 4 Task 1 (Assessment Criteria P1) Consider yourself working on a Research and Development team, doing research on how to improve the efficiency of a jet engine. You have been tasked to describe the basic principles of jet propulsion using simple equations as per your group. Group A a. Newton’s 2nd law b. Thrust Equation c. Specific fuel consumption Group B a. Mass flow rate b. Thrust Equation c. Kinetic and Thermal Efficiency Task 2 (Assessment Criteria P2 & M1) Most modern passenger and military aircraft are powered by gas turbine engines, which are also called jet engines. The first and simplest type of gas turbine is the turbojet. Your manager has asked you to draw a sketch of the working cycle of a gas turbine engine, as well as explain the working cycle of a gas turbine engine and the relationship between pressure, velocity, volume and temperature. Task 3 (Assessment Criteria P3) Every gas turbine engine has these three sections – a compressor, a combustion section (burner) and a turbine. The compressor, burner, and turbine are called the core of the engine. Describe the purpose of these three sections of a gas turbine engine. Evidence Checklist Summary of evidence required by students P1 Learners have to submit a word process report by describing the principles of jet propulsion using simple equations. Learners are required to sketch the working cycle of a gas turbine engine. Learners have to submit a word process report providing the description of the purpose of three sections of a gas turbine engine. Evidence for M1 would be best obtained by extending the task (sketch) needed for P2, to include the explanation of the working cycle of a gas turbine engine in terms of pressure, velocity, volume and temperature.
