Design and Testing of a Hovercraft with Electroaerodynamic Propulsion
… makes MSD thrusters well-suited for use in EAD hovercraft, where generating sufficient pressure is crucial for hovering. This study explored the feasibility of a wire-to-airfoil corona discharge MSD thruster powered hovercraft through a scaled-down prototype and final design. The hovercraft was …

SPH Simulation of Fluid-Structure Interaction Problems with Application to Hovercraft
A Computational Fluid Dynamics (CFD) tool is developed in this thesis to solve complex fluid-structure interaction (FSI) problems. The fluid domain is based on Smoothed Particle Hydro-dynamics (SPH) and the structural domain employs large-deformation Finite Element Method (FEM). Validation tests of …

Modification of a Full Scale Personal Hovercraft to Support Research in Dynamics and Control
… this thesis are to modify a full-scale personal hovercraft to perform autonomous maneuvers on flat ground, develop a first principles of the craft, and present data on the vehicle behavior in field trials. The hovercraft, initially designed for manual control by a rider, was modified both …

Multirobot Tethering for Localization and Control
… of particle filter estimation techniques on a hovercraft vehicle. The marginally stable dynamics of a hovercraft require reliable state estimates for proper stability and control. We use the Monte Carlo localization method, which implements a particle filter in a recursive state estimate …

Handling hovercrafts : designing a project curriculum to introduce girls to mechanical engineering
… girls' interest in design and manufacturing. A hovercraft design contest was chosen as the basis for the project because of the range of concepts it encompasses and because the competitive nature of the project would encourage cooperation and motivation among the students. To test the project's …

The commercial and technical evolution of the ferry industry 1948-1987
… came the innovation of roll-on, roll-off and the hovercraft, with ports undergoing change scarcely less extensive. The thesis examines the basic structural changes that affected the industry, specifically the process that resulted in the establishment of privately-owned firms in situ, the …

A Greedy Search Algorithm for Maneuver-Based Motion Planning of Agile Vehicles
… the goal. Using simulations of a four-thruster hovercraft, AD-Lib is compared to existing suboptimal search algorithms in both known and unknown environments with static obstacles. AD-Lib is shown to be faster than existing techniques, at the expense of increased path cost. The motion planning …

A model predictive control approach to a class of multiplayer minmax differential games
… is a custom-built robotic testbed named HoTDeC (Hovercraft Testbed for Decentralized Control). The outdoor testbed involved full-sized US Naval Academy patrol ships, and the experiment was conducted in Chesapeake Bay in collaboration with the US Naval Academy. The scenario used involved one ship …
