| DESCRIPTION | This study-unit is made up of three main parts: - The introduction of the fundamental concepts and laws governing thermo-fluids. - The application of such laws to the gas turbine engine and the role of various engine components. - The overall performance of gas turbines. The study-unit covers: - The fundamental concepts of Ideal gas laws; - The fundamental concepts of Energy and momentum conservation and Newton's laws of motion; - The fundamental laws of thermodynamics; - The concepts of thermodynamic efficiency and thermodynamic cycles; - An overall description of different gas turbine architectures; - Detailed description of the main components and the role of materials; - Overall gas turbine theory and performance; - Gas turbine parameters and efficiencies in the context of propulsion; - The Atmosphere and its effects on engine performance; - Gas Turbine Performance Simulation; - A look into future engine concepts and their intended benefits. Study-Unit Aims: This study-unit provides the student with an overall view of the gas turbines and their application as a propulsive power plant in aircraft. The student following this study-unit should develop an appreciation for this technology and its contribution to aviation. The study-unit will focus on design and performance of gas turbines and demonstrate the challenges in achieving higher efficiencies and greener travel. Specifically this study-unit aims to: - Describe the thermodynamics of gas turbine theory; - Describe the role of the main components and its principles of operation; - Highlight the relationship between gas turbine parameters such as specific fuel consumption and specific thrust; - Describe the overall gas turbine theory and calculate performance as a result of the components working together. Learning Outcomes: 1. Knowledge & Understanding: By the end of the study-unit the student will be able to: - Explain and calculate the state of gases based on the ideal gas laws; - Describe the laws of conservation of energy; - Describe Newton's laws of Motion; - Describe the laws of thermodynamics and calculate states based on thermodynamic cycles; - Explain the general gas turbine architecture and power plant derivatives; - Describe the role of the main components, operation and limitations; - Explain important parameters in the context of gas turbine performance and propulsion (SFC, bypass ratio, propulsive efficiency, core thermal efficiency); - Calculate the expected gas turbine performance based on a given set of parameters; - Explain how the atmosphere is modeled to describe operating conditions; - Explain the effects of atmospheric conditions on gas turbine performance; - Describe future thermodynamic concepts and future trends in gas turbine design for improved efficiency in the context of increased environmental awareness. 2. Skills: By the end of the study-unit the student will be able to: - Assess general thermodynamic knowledge and their role in gas turbines; - Compare different gas turbine architectures; - Assess the role of different gas turbine components; - Analyse efficiency terms and important gas turbine parameters; - Assess the performance of a gas turbine at a given condition; - Compare emerging concepts in the context of aviation/environmental awareness; - Apply the achieved scientific knowledge to their day to day activity.
