Aims
This module aims to develop and extend the treatment of fluid mechanics to two-dimensional low speed flow and one-dimensional compressible flow; introduce the concepts of boundary layer theory; sources of drag (particularly aircraft drag); develop thin aerofoil theory and apply to the aerodynamic analysis of aerofoil sections in low speed flow; develop lifting line theory and apply to the aerodynamic analysis of unswept wings in low speed flow; describe the apparatus used and techniques employed in wind tunnel testing, analyse the inviscid aerodynamic performance of an aerofoil section over a range of Mach numbers, from low subsonic to hypersonic conditions.
Learning Outcomes
1.
Analyse the properties of air and the atmosphere.
2.
Calculate the effect of forces on the aerodynamic characteristics of aircrafts/vehicles.
3.
Carry out investigations of the forces on various profiles under subsonic incompressible flow conditions
4.
Apply the aerodynamic characteristics of wings with various profiles under various flow regimes (subsonic incompressible, subsonic compressible, transonic, supersonic).
