Description

Aerofoil theory; Flat plate lift and drag; Aerofoil lift and drag; Predicting aerofoil data with Xfoil; Boundary layer theory; Aircraft performance; Stability and control in flight; Wind tunnel testing; Glider design, build and test; Propeller design; BEMT method; High speed (compressibility) effects; Wheeled ground vehicles: load transfer, tyre design, traction and rolling resistance, aerodynamics, suspension, steering, and potential flow.

This course teaches the fundamental understanding, and some of the design skills, required for aerodynamic design in the aviation and automotive industries, with relevance also to the wind and hydroelectric power industries. The course strengthens skills required for almost any industrial application with moving fluids.

For the Mechanical Engineering Aerospace Minor, students must select two of the following options: ENME404, ENME460, ENGR401, and Special Topics 2024 ENME422 and ENME488.
