Abstract
The objective of this research was to develop a highly precise aerodynamic model of an airship through the utilization of a six degree of freedom Simulink simulation, followed by integration with X-Plane 11 to enable pilot-in-the-loop functionality. This work was inspired by prior research conducted by S. B. V. Gomes on the flight dynamics of airships, with specific reference to the YEZ-2A, an ellipsoid shaped aircraft measuring 425 feet in length and 105 feet in diameter, possessing a gas envelope of 1.7 million cubic feet which permits buoyancy control via ballonets. Our model was generated using the MATLAB programming language, in conjunction with Simulink and X-Plane 11 flight simulation software. We extracted a broad array of aircraft flight parameters from Gomes' wind tunnel test results, enabling us to construct the most accurate model feasible. We imported sixty data sets encompassing maximum control surface deflection and over 30 degrees in both side slip and angle of attack for precise interpolation. Future work will involve the integration of a ground-based tether into the model, which will facilitate ground control, data collection, and power transmission to the airship in real time. This research was instigated by the extensive expertise of Dr. Brandon Buerge at Wichita State University in the field of airships and lighter-than-air vehicles, as well as private sector interest. Airships are ideal for remote, high-endurance, long-range missions, making this research area exceptionally stimulating.
