A Unified, Configurable, Non-Iterative Guidance System For Launch Vehicles
(2011-02-10)
A satellite launch vehicle not subjected to any perturbations, external or internal, could be guided along a trajectory by following a stored, pre-computed steering program. In practice, perturbations do occur, and in order ...
Investigation Of Ramp/Cowl Shock Interaction Processes Near A Generic Scramjet Inlet At Hypersonic Mach Number
(2010-08-05)
One of the major technological innovations that are necessary for faster and cheaper access-to-space will be the commercial realization of supersonic combustion jet engines (SCRAMJET). The establishment of the flow through ...
Multi-Agent Search Using Voronoi Partition
(2010-08-05)
This thesis addresses a multi-agent search problem where several agents, equipped with sensors and communication devices, search an unknown area. Lack of information about the search space is modeled as an uncertainty ...
The Effect Of Energy Deposition In Hypersonic Blunt Body Flow Field
(2010-09-23)
A body exposed to hypersonic flow is subjected to extremely high wall heating rates, owing to the conversion of the kinetic energy of the oncoming flow into heat through the formation of shock waves and viscous dissipation ...
Dynamic Response Of A Satellite With Flexible Appendages And Its Passive Control
(2010-11-25)
Most present day spacecrafts have large interconnected solar panels. The dynamic behavior of the spacecraft in orbit can be modeled as a free rigid mass with flexible elements attached to it. The natural frequencies of ...
Odor Source Localization Using Swarm Robotics
(2010-06-02)
Locating an odor source in a turbulent environment, an instinctive behavior of insects such as moths, is a nontrivial task in robotics. Robots equipped with odor sensors find it difficult to locate the odor source due to the ...
Motion Optimistion Of Plunging Airfoil Using Swarm Algorithm
(2010-06-03)
Micro Aerial Vehicles (MAVs) are battery operated, remote controlled miniature flying vehicles. MAVs are required in military missions, traffic management, hostage situation surveillance, sensing, spying, scientific, rescue, ...
A Study Of A Vortex Particle Method For Vortex Breakdown Phenomena
(2010-07-06)
Vortex breakdown is an important phenomenon observed in swirling flows involving the development of a stagnation point on the axis of the vortex followed by a region of recirculation when the swirl increases beyond a ...
