Objectives

To offer an integrated understanding of the basic principles of engineering thermodynamics, fluid mechanics and heat transfer, combustion fundamentals and how these principles impact the design and operation of aircraft and their systems.

Learning outcomes
The completion of this course should enable the Aviation Technology students to form a solid foundation for applying these subjects to the topics covered in later modules, as required in their individual programmes. Moreover, the students would gain a coherent understanding of the above mentioned basic subjects in a single module.

Main outcomes:
- Understanding of the basic principles of fluid flow, thermodynamics, heat transfer and combustion as they apply to the aviation industry, aircraft systems and aerodynamic flow.
- Fundamental knowledge of hydraulics and pneumatics so as to be able to understand the operation of aircraft hydraulic systems.
- Understanding of the combustion processes in aircraft engines and the ability to perform combustion calculations.
- Basic knowledge of heat transfer applied to commercial aircraft operations.
- Appreciation of the mechanics of air flow around solid bodies and lifting surfaces across a wide range of speeds and how this sets the scene for aerodynamics and hence flight.

Skills outcomes
Students should gain a sound knowledge of the terminologies used, of the fundamental laws and equations and be able to perform basic level calculations in the key subject areas of fluid mechanics, engineering thermodynamics, heat transfer and combustion.

Students should acquire the ability to identify how the material covered relates to aviation.

Syllabus

Fluid Mechanics
Fundamentals of fluid mechanics: fluid properties, basic dimensions and units, Newton's law of viscosity; fluid statics: Pascal's Law; pressure measurement; fluid dynamics: Bernoulli equation, air speed measurement; flow control: hydraulic pressure transmission and storage systems, valves, pumps, flow metering. Aerodynamics: potential flows: streamlines, vectors, gradients, divergence of flow; flow over immersed bodies: laminar and turbulent flows, Reynolds number, rotational and irrotational flows, boundary layers, pressure gradients, steady and unsteady flow, flow separation, stagnation point, adverse pressure gradients, shock waves. Examples of how the above impact the design and operation of aircraft.

Thermodynamics
Basic concepts of thermodynamics - system, state, state postulate, equilibrium, process, and cycle. Review concepts of temperature, temperature scales, pressure, and absolute and gauge pressure. 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. The physics of phase-change processes. P-v, T-v, and P-T property diagrams. Application of the first law of thermodynamics to control volumes. The total energy carried by a fluid stream and the relationship between internal energy and flow work to enthalpy. Energy balance problems for common steady-flow devices such as nozzles, compressors, turbines, throttling valves, heaters, and heat exchangers. Examples of how the above impact the design and operation of aero engines and other aircraft systems.

Heat Transfer
Concepts applied to aviation - heat transfer of conduction, convection, radiation; thermal and hydrodynamic boundary layers, conduction through multi-layer walls; insulation and thermal expansion of aircraft components. Examples of how the above impact the design and operation of aircraft.

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