Content, Learning Outcome and Preconditions


"The module Unsteady Aerodynamics II is concerned with the numerical treatment and the application of the unsteady lifting surface theory deduced in the module Unsteady Aerodynamics I. Thereby, the complete Mach number range is concerned. Besides the motion induced aerodynamic forces, the forces resulting from unsteady inflow (gust) are analyzed. Contents:
- Pressure distribution around the harmonically oscillating airfoil in incompressible and subsonic flow: kernel function of the lifting surface equation, set-up functions of pressure distribution collocation methods, exact solution; rudder oscillations
- Pressure distribution around the harmonically oscillating airfoil in sonic, supersonic, and hypersonic flow
- Lifting surface theory for arbitrary unsteady processes: Fourier synthesis, Laplace transformation, Duhamel synthesis, direct method for supersonic flow
- Plane wing of finite span: kernel functions, collocation methods (subsonic flow), integral method and integral equation method (supersonic flow)
- Interfering lifting surfaces"

Learning Outcome

"After successful participation in the module, the student is able to:
- characterize the pressure distribution resp. air forces for problems, concerning the harmonically oscillating airfoil in incompressible, subsonic, sonic, supersonic and hypersonic flow
- present different calculation methods for solving the lifting surface theory for arbitrary unsteady processes
- apply the integral equation of the unsteady lifting surface theory to determine the pressure distribution around a wing of finite span in subsonic flow
- demonstrate and apply the procedure to determine the unsteady air forces around a wing of finite span in supersonic flow
- analyze the effect of flap and rudder oscillations"
