(Indian Institute of Science, 2006-11-17)This thesis presents the results and analyses of computational studies on certain problems of combustion instability in solid propellants. Specifically, effects of relaxing certain assumptions made in previous models of ... -
A Computational Study of Structural and Thermo-Mechanical Behavior of Metallic Nanowires
(2018-04-11)This thesis is an attempt to understand ways to improve thermo-mechanical and structural properties of nano-structured materials. A detailed study on computational design and analysis of metallic nanowires is carried out. ... -
Constrained Adaptive Control of Nonlinear Systems with Application to Hypersonic Vehicles
Constraints in input, output, and states are evident in most of the practical systems. Explicitly incorporating these constraints into the control design process leads to its superior performance in general. Therefore, ... -
Constrained Optimal Guidance Design of Interceptors for High-Speed Ballistic Targets
In this thesis, optimal control theory has been applied to design constrained terminal guidance algorithms for interceptor to destroy incoming high speed ballistic targets. There exist several optimal guidance algorithms ... -
Continuous-Curvature Path Planning Using Four Parameter Logistic Curves
Autonomous vehicles perform time and cost effective operations with minimal or no human effort and hence, have the potential to be used in civilian, commercial and military applications. Pertaining to these applications, ... -
Control and Safety of Multi-UAV Systems for Collaborative Payload Transportation and Target Tracking
Unmanned aerial vehicles (UAVs) have been widely used in reconnaissance, remote sensing, disaster relief, and agricultural applications. Many applications require multiple UAVs to cooperate to complete the assigned tasks. ... -
Control of Alternating Flow Phenomena in Transonic Shock Wave Boundary Layer Interactions Over Payload Region of a Generic Launch Vehicle Model
During the transonic phase of a launch vehicle’s ascent, aerodynamic loads peak due to high freestream dynamic pressure and angle of attack. In addition to steady loads, significant pressure fluctuations arise from Shock ... -
Control of shock-induced vortex breakdown in Transonic regime on a slender delta wing body configuration using blowing
Modern high speed aircrafts feature highly swept and low aspect ratio wings, mainly to increase the critical Mach number and reduce the wave drag. A special case of swept wings is wings with triangular planform commonly ... -
Cyclic Pursuit : Variants and Applications
(2018-02-11)The classical n-bugs problem has attracted considerable attention from researchers. This problem stems from the study of movement of a group of animals. In the context of multi- agent systems the problem has been modelled ... -
Decentralized Sustainable Energy Planning For Tumkur District, India
(2010-02-18)The energy-planning involves finding a set of sources and conversion devices so as to meet the energy requirements/demands of all the activities in an optimal manner. This could occur at centralized or decentralized level. ... -
Decongestion Strategies for Dense Urban Airspace
With the rapid growth in the number of uncrewed aircraft systems (UAS) being deployed for on-demand delivery applications, severe congestion is anticipated in the low-altitude class-G urban airspace. Thus, there is a need ... -
Deformation-based Topological Lattices and their Edge States
Topological elastic metamaterials (TEMs) represent a novel class of elastic materials known for their unique ability to localize vibration energy at boundaries, maintaining robustness against system disorders. These ... -
Delamination Modeling and Detection in Composite Structures
(2017-12-12)Composite laminated structures are prone to delamination. Rotorcraft flexbeams, apart from many other aerospace primary load carrying members are made up of composite laminated structures. A delaminated primary load carrying ... -
Demonstration Of Supersonic Combustion In A Combustion Driven Shock-Tunnel
(2011-01-17)For flights beyond Mach 6 ramjets are inefficient engines due to huge total pressure loss in the normal shock systems, combustion conditions that lose a large fraction of the available chemical energy due to dissociation ...
