Info

the simulation is transportable to any platform. More digital and analog hardware can beimplemented in the simulation allowing further research into futuristic cockpit displays orimbedded avionics. Due to the networking capability of the simulation, simulators can beadded as long as there is enough bandwidth. Desktop simulators or other analogsimulators can be added to the simulation to develop a simulation arena.1.2 SoftwareThe simulation integrates C-code with Matlab’s Simulink S-Function AppliedProgrammer’s Interface (API). Simulink’s Graphical User Interface (GUI) allows theuser to see the variables flow through the simulation. At any time, the user can monitor orgraphically display one of the variables and plot it as a function of time. This is far betterthan debugging in most common compilers since Simulink allows the programmer to seethe variables in real-time. Simulink also allows the simulation to be broken down intosubsystems and individual simulation models. These models can be individually tested oradded to a completely different simulation.Simulink’s S-Function API allows any C-Code to be integrated into thesimulation. This allows the implementation of other API’s into the simulation. OpenGVSis another API that uses OpenGL code to generate a Realtime Scene Management forThree-Dimensional Visuals. OpenGVS has specific functions that enable the threedimensionalenvironment to be changed such as camera position, lighting, and visibility.1.3 PhEagle Archive2
The simulation laboratory needs to continue its ongoing development. This meansthat running and developing the simulator needs to become easy to learn in the shortesttime possible. The development of the PhEagle Virtual Library enables senior projects,thesis work, research, and simulation models to be well documented, stored, and easilyaccessible, so students can begin where the last student finished. This will allow thesimulator’s development to be ongoing and keep up with industry. Included are tutorialsand demos, which teach the students how to create a simulation and learn differentaspects of the simulator. The Pheagle Operations Manual thoroughly describes how torun the simulator and how to test and calibrate any of the hardware, instruments, orsimulations.1.4 Research ObjectivesThe initial goal was to develop a visual systemfor the simulator that led to the development of anInstrument Landing System (ILS) Simulation. Beforethis could happen, the simulator had to be moved intothe new Northrop Grumman Aerospace SystemLaboratory in the Advanced Technology Laboratories(ATL) building at Cal Poly, San Luis Obispo, shownin Figure 1. This led to the development of the newFigure 1:Advanced Technologies Laboratories(ATL)simulation laboratory.In order for the ILS simulation to work, an adequate engine model had to bedeveloped. Also the ILS and CDI instruments were not working at the time of3
