Six Degrees Of Freedom Modeling and Simulation of Aerospace Vehicle- D240

Summary:

This is a two-day course. As modeling and simulation (M&S) is penetrating the aerospace sciences at all levels, this course will introduce you to the difficult subject of modeling aerospace vehicles in six degrees of freedom (6 DoF). Starting with the modern approach of tensors, the equations of motion are derived and, after introducing coordinate systems, they are expressed in matrices for compact computer programming. Aircraft and missile prototypes will exemplify 6 DoF aerodynamic modeling, rocket and turbojet propulsion, actuating systems, autopilots, guidance, and seekers. These subsystems will be integrated step by step into full-up simulations. For demonstrations, typical fly-out trajectories will be run and projected on the screen. The provided source code and plotting programs let you duplicate the trajectories on your PC (requires MS Visual C++ compiler, free Express version). Based on these prototype simulations you can build your own 6 DoF aerospace simulations.

Attendees receive all course slides, the C++ source code of the aircraft and missile simulations, and access to the full CADAC++ simulation framework and plotting software used in this course. It is recommended, though not required, that the attendees bring with them Dr. Zipfel’s textbook “Modeling and Simulation of Aerospace Vehicle Dynamics”, 3rd Ed, 2014, published by AIAA.
