6 Abstract The Cal Poly Flight Simulation Laboratory was in need of the addition of computercontrolled aircraft in its world environments to allow for handling tasks that would help evaluate the design of the piloted aircraft. A graphical user interface was created using MatLab code to generate the tabular text file of time and space coordinates required by the 3DLinx key frame navigation tool. The resulting program, Chase, is a simple, user-friendly tool allowing for the completion of this task, as well as being able to be adapted to the future needs of the sim.
7 Introduction The Cal Poly Flight Simulation Lab has provided a resource for aerospace engineering students to apply their knowledge of aerodynamics, structures and controls, as well as to develop their computer programming skills. The simulator was built and is maintained by students with an interest in flight simulation. More than just a hobby, however, recent aircraft design students have used the simulator to validate and support their work for submission to the AIAA Team Undergraduate Design Competition. It has also been used to perform grant work for companies such as the Lockheed Martin Aeronautics Company in Palmdale (The Skunk Works) and NASA Ames. The flight sim is run with a MatLab Simulink model. The aircraft controls are modeled through a table lookup system of control coefficients. The coefficients are calculated based on the methods detailed in the design texts by Roskam. The graphical world through which the pilot navigates is modeled in the 3DLinx environment. To improve the functionality of the flight sim, this project is focused on adding additional, realistically behaving aircraft to the flight sim world. These aircraft can be tanker or fighter aircraft. This addition will serve both to increase interest in the simulator and to provide students with a handling task that could be used to evaluate various control system arrangements including stick force feedback and control surface sizing. To make this process as easy as possible, it was decided to implement a graphical user interface (GUI) designed in the MatLab environment to generate the text file of waypoints needed to control an object in the 3DLinx graphics world. These text files can then be easily uploaded to an object in a given 3DLinx world file to create the desired result.
