One of the main goals of robotics research is to give physical platforms intelligence, allowing for the platforms to act autonomously with minimal direction from humans. Motion planning is the process by which a mobile robot plans a...
At the beginning of this century, some societies have shifted, or at least recognized the need to shift, towards a more renewable way of living, this shift has initiated a movement to reduce the carbon footprint, and new standards are...
Vortex asymmetry develops on slender bodies at high angles of incidence, leading to large side-forcesand yaw moments even in symmetrical flight conditions. This unexpected side force can be large for the control surfaces to produce a...
A device that can be used to attenuate noise generated in an engine nacelle of an aircraft is an acoustic liner. A conventional single degree of freedom (SDOF) acoustic liner is comprised of a perforated face sheet, honeycomb cells, and...
At high angles of attack, asymmetric vortices are formed on the leeward side of flight vehicles with pointed forebodies due to the random surface imperfections near the forebody apex. These vortices induce adverse side forces and yaw...
Legged mobile robots have a number of distinct advantages over wheeled or flight-enabled platforms, including optimal foot placement and task- or terrain-specific gait strategies. When analyzing a legged robot, the use of reduced order...
Fluid dynamic characterization of shock impingement on a flat surface has been studied extensively, whereas the material behavior induced by the shock has largely been ignored. The focus of this study is mainly on the material and...
Pressure-gradient-induced (PGI) turbulent separation bubbles (TSBs) are a common occurrence in various fluidic devices and systems. When a separation bubble forms due to an adverse pressure gradient as opposed to a geometric...
Everyday animals maneuver through complex unstructured environments provided by the natural world. One way in which we can study these behaviors in animals is by partitioning the natural world into differing domains and analyzing the...
Active flow control (AFC) has the potential for substantial performance gains and meeting the challenges of next-generation high-lift aircraft. High-lift wings employ multi-element trailing edge flaps during takeoff and landing. When the...
The need for increased efficiency and performance of high-speed aircraft has led to the need for a reduction in aircraft weight. One option is to use thinner and lightweight skin panels at different regions of the aircraft, such as the...
Polytetrafluoroethylene (PTFE) is a thermoplastic polymeric material that is chemically inert, vacuum compatible, has a low surface energy, and has a large operating temperature range due to its high melting temperature. PTFE is also the...
