NPSNET: Flight Simulation Dynamic Modeling Using Quaternions
NAVAL POSTGRADUATE SCHOOL MONTEREY CA
Pagination or Media Count:
The Naval Postgraduate School NPS has actively explored the design and implementation of networked, realtime, three-dimensional battlefield simulations on low cost, commercially available graphics workstations. The most recent system, NPSNET, has improved in functionality to such an extent, that it is considered a low cost version of the Defense Advanced Research Project Agencys DARPA SIMNET system. In order to reach that level, it was necessary to economize in certain areas of the code so that real time performance occurred at an acceptable level. One of those areas was in aircraft dynamics. However, with off-the-shelf computers becoming faster and cheaper, real-time and realistic dynamics are no longer an expensive option. The realistic behavior can now be enhanced through the incorporation of an aerodynamic model. To accomplish this task, a prototype flight simulator was built that is capable of simulating numerous types of aircraft simultaneously within a virtual world. Beside being easily incorporated into NPSNET, such a simulator will also provide the base functionality for the creation of a general purpose aerodynamic simulator that is particularly useful to aerodynamic students for graphically analyzing differing aircrafts stability and control characteristics. This system is designed for use on a Silicon Graphics workstation and uses the GL libraries. Computer Graphics, Animation, Simulation, Aerodynamics, Quaternions.
