SESA2022 Aerodynamics

Module Overview

In this module the fundamental concepts of aerodynamics are introduced. The main focus is on inviscid, incompressible flow, but compressible and viscous effects will be introduced. The lectures are complemented by laboratory sessions with relevance to the taught material.

Aims and Objectives

Module Aims

To introduce a range of core material in aerodynamics, including potential flow, simple theories for 2D aerofoils and 3D finite wings, 1D gasdynamics, real (viscous) flow effects.

Syllabus

Introduction: Fundamental concepts: Velocity field, streamlines & streamfunctions, Euler's & Bernouilli's equations, vorticity & irrotational flow, velocity potential, role of Laplace equation. Flow elements and superposition: Uniform stream, source/sink, line vortex, uniform flow with source, Rankine oval, flow around circular cylinder/doublet, circulation, lifting flow over circular cylinder and Kutta-Joukowski theorem, Kutta condition, method of images. Thin Aerofoil Theory: Vortex sheets, flat plate aerofoil (Glauert intergral, lift-versus-angle of attack, aerodynamic centre & centre of pressure), cambered aerofoil (lift-versus-angle of attack), surface loading/pressure distribution. Finite Wing Theory: Downwash & induced drag, Biot-Savart law, bound vorticity, horseshoe vortex, classical lifting line theory, application to elliptic & general wing planforms. Introduction to compressible flow: Introduction, review of thermodynamics concepts, isentropic flow, speed of sound, Mach number, stagnation conditions, sonic conditions, normal shock waves, entropy considerations. Internal flow: Internal flow with area change, converging-diverging nozzle, choked flow, design condition, critical pressure ratio & mass flowrate, effect of back pressure on nozzle flow.
