Propeller And Propeller-In-Wing Thrust Vectoring, Grace G. Culpepper
Propeller And Propeller-In-Wing Thrust Vectoring, Grace G. Culpepper
Honors Theses
This research investigates the efficiency of a vane-based thrust vectoring system set in the wake of a propeller, supporting forward force at a minimum loss in net thrust. The vectoring system itself is placed in both a standalone propeller configuration and a propeller-in-wing configuration. Both static and wind-on force-based experiments are conducted at the University of Dayton Low Speed Wind Tunnel (UD-LSWT) with off-the-shelf R/C propellers. Sensitivity analysis determines both the effect of vane deflection angle on thrust vectoring and the effect of propeller placement with respect to the upper surface of the integrated wing on system performance. Static test …

Development Of A Computational Framework For Estimating Knee Joint Contact Forces In Running, Sean W. Kapp
Honors Theses
The prevalence of running as a form of exercise and the necessity of walking for simple locomotion obscure massive forces and moments within the body. An especial area of concern is the knee, as common among these injuries is knee pain as a result from high impact on the ground or ground reaction forces. These forces are altered by the foot strike pattern of the individual; in this study, either rearfoot strike (RFS) or forefoot strike (FFS). This alteration will impact internal forces conducted upward through the body. Given the complexity of the motion of running and the forces involved, …
