Application and analysis of the Prandtl Bell Spanload

Robb, Caleb
This thesis focuses on exploring the potential applications of the Prandtl Bell Spanload concept. The initial objective of this study is to assess the feasibility and benefit of implementing spanloading in a flying-wing concept aircraft. Substantial design efforts were dedicated to developing a comprehensive plant model, which served as the foundation for conducting dynamic simulations of the aircraft. During these simulations, an issue arose concerning the overestimation of roll-yaw coupling effects. To address this concern, an alternative force-moment prediction method was investigated for potential use in future simulation endeavors. Furthermore, this research extends to the application of the Prandtl Bell Spanload concept in the design of a novel propeller concept, which underwent rigorous computational testing. The project has advanced to the experimental phase, indicating progress in practical implementation.
