Effectiveness of adaptive flight planning in the occurrence of total loss of thrust due to bird strike
As of today, more than 96 percent of air travelers are transported on twin-engine jets. Although contemporary twin-engine jets are more reliable and efficient than yesterday’s three- and four-engine jets, they have reduced engine redundancy. A statistical analysis of the FAA Wildlife Strike …

Optimal Control in Aircraft Trajectory Planning
… geometric constraints but also full six-degree-of-freedom dynamics, actuator limits, and mission- or safety-driven performance objectives. This thesis investigates optimal control as a refinement tool for trajectory-planning problems that are typically addressed using geometric or search-based …

Autonomous Underwater Vehicle (AUV) Propulsion System Analysis and Optimization
One of the largest design considerations for autonomous underwater vehicles (AUV's) that have specific mission scenarios is the propulsive efficiency. The propulsive efficiency affects the amount of power storage required to achieve a specific mission. As the efficiency increases the volume of …

A Computational Framework for Simulating Entanglement-Based Drone Countermeasures with Flexible Filaments Immersed in Viscous Flow
… for modeling the coupled dynamic interactions of highly flexible slender filaments immersed in a viscous flow and their entanglement with themselves and moving structures. This work is motivated by a novel drone countermeasure that entangles propellers with flexible filament clouds, inducing a …

A STUDY ON THE PHYSICS OF ICE ACCRETION IN A TURBOFAN ENGINE ENVIRONMENT
Numerous turbofan engine loss of thrust control events have led to a theory that ice is accreting on initially warmer than freezing internal engine hardware and affecting normal operation. The phenomenon is termed ice crystal icing. Previous ice crystal icing research on a simple airfoil …
