Six Degrees of Freedom Modelling & Simulation of Aerospace Vehicles

Course Description

As modeling and simulation (M&S) is penetrating the aerospace sciences at all levels, this two-day course with presenter Prof Allen Greenwood, 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 lets you duplicate the trajectories on your PC (requires FORTRAN or C++ compiler). With the supplied textbook "Modeling and Simulation of Aerospace Vehicle Dynamics" and the prototype simulations you can build your own 6 DoF aerospace simulations.

Target Audience

This course is valuable for engineers tasked to employ, modify or develop detailed aerospace vehicle simulations and to conduct performance evaluations. Some familiarity with vehicle dynamics and control is assumed, but no prior knowledge of simulations is required.
