This module is not approved as a discovery module

Module summary

This module aims to introduce the students to:(i) the fundamental scientific principles which underpin the design and operation of aircraft,(ii) the methods used to communicate technical/engineering data and(iii) the wider factors that must be considered when designing aircraft.Each of these aspects will be firstly presented to the students and then they will be given the chance to incorporate them in hands-on design activities.

Objectives

The module aims to equip students with an understanding of the fundamentals of fluid mechanics, thermodynamics, heat transfer and combustion and to relate these to aviation through laboratory investigations and a design project. The labs will also focus on the development of the students' technical skills and the design project will also focus on consideration of social, environmental and ethical impacts.

Learning outcomes
At the end of the module, students should be able to:
1. Describe and explain the basic principles of fluid mechanics, thermodynamics, heat transfer and combustion.
2. Perform basic level calculations in fluid mechanics, thermodynamics, heat transfer and combustion.
3. Gather information, reference and critically assess this in the form of a literature review.
4. Follow experimental procedures.
5. Analyse, present, model and critically assess experimental data.
6. Use word processing and spreadsheet software to prepare technical or laboratory reports.
7. Understand plagiarism and how to avoid it.
8. Combine the knowledge/skills obtained in previous learning outcomes and apply them to aircraft design.

Skills outcomes
Students acquire the following competencies in the module. In each case, the means of acquiring the competency is shown. These competencies correspond with those specified in "The Accreditation of Higher Education Programmes", Third edition, Engineering Council, 2014. . P = practiced ACTIVELY, F= Formatively Assessed, S = Summatively Assessed.

Review concepts of temperature, temperature scales, the zeroth Law. Overview of the four laws. Pressure, and absolute and gauge pressure. Forms of energy, the concepts of heat and work and the associated terminology. The first law of thermodynamics, energy balances, and mechanisms of energy transfer to or from a system. The flow energy of a fluid. Energy conversion efficiencies, pumps and turbines. The physics of phase-change processes. P-v, T-v, and P-T property diagrams, saturation properties. Property tables. Moving boundary work. Energy balance for closed systems. Internal energy, enthalpy and specific heats for ideal gases, liquids and solids. Conservation of mass, mass and volume flow rates, incompressible flow. Energy of a flowing fluid. Mass and energy balances for steady flow processes. Steady-flow devices such as nozzles, compressors, turbines, throttling valves, heaters, and heat exchangers. Examples and application to aviation and aircraft systems throughout.

Heat Transfer
Relationship between thermodynamics and heat transfer, overview of heat transfer mechanisms: conduction, convection, radiation - significance in aviation.
Heat exchangers: classification, co- and counter- flows, shell and tube heat exchangers, compact heat exchangers, fouling, design and analysis of heat exchangers, the Log Mean Temperature Difference Method, selection of heat exchangers.
Examples and application to aviation and aircraft systems throughout.

Combustion
Focused on aero engine applications. Combustion chemistry, fuel chemistry, characteristics of gasoline, kerosene, diesel and alternative fuels, combustion principles in internal combustion engines, combustion thermodynamics, calculation of combustion temperature, use of conventional thermodynamic tabulations, engine emissions. Examples of how the above impact the design and operation of aero engines.

Technical Skills
