Aeroelastic Analysis with MSC Nastran Training Course (NAS111)
This course is intended for engineers concerned with structural loads, flying qualities, and aeroelastic stability of flexible aircraft and missiles. The objective of the course is to familiarise the engineer with state-of-the-art MSC Nastran applications in aeroelastic analyses. An overview of the aeroelastic capability is followed by an in-depth discussion of the available aerodynamic theories and the three available aeroelastic solutions: static aeroelasticity, flutter, and dynamic aeroelasticity. Advanced topics include modelling aerodynamic bodies, active control systems, the specification of dynamic loads, sensitivity analysis, and aeroelastic optimisation.
