Application of Randomized Algorithms in Path Planning and Control of a Micro Air Vehicle
(2018-06-25)
This thesis focuses on the design and development of a fixed wing micro air vehicle (MAV) and on the development of randomized sampling based motion planning and control algorithms for path planning and stabilization of the ...
Effect of Favourable Pressure Gradient on Turbulence in Boundary Layers
(2018-07-16)
This thesis explores the effects of favourable pressure gradient on the structure of turbulent boundary layers (TBL). In this context, the structure of three types of boundary layers namely a zero-pressure-gradient ...
Sliding Mode Control Based Guidance Strategies with Terminal Constraints
(2018-07-23)
In the guidance literature, minimizing miss distance along with optimizing the energy usage had been an objective for several decades. In current day applications, additional terminal performance such as impact angle and ...
Differential Games Guidance Laws for Aerospace Applications
(2018-07-26)
This thesis addresses several aerospace guidance and decision making problems using both no cooperative and cooperative game theoretical solution concepts in the differential games framework. In the first part of the thesis, ...
Synchronized and Balanced Collective Formations in Multi-Agent Systems
(2018-07-14)
Multi-agent systems possess improved robustness properties over single agent systems, and hence, are more desirable for various engineering applications, where it is required for the multiple agents to move in a formation. ...
An Integrated Estimation-Guidance Approach for Seeker-less Interceptors
(2018-07-16)
In this thesis, the problem of intercepting highly manoeuvrable threats using seeker-less interceptors that operate in the command guidance mode, is addressed. These systems are more prone to estimation errors than standard ...
Experimental Studies on the Effect of an Upstream Periodic Wake on a Turbulent Separation Bubble
(2018-06-26)
The object of the present work is to experimentally study the case of a turbulent boundary layer subjected to an Adverse Pressure Gradient (APG) with separation and reattachment. The effect of unsteadiness on turbulent ...
Experimental Analysis of Shock Stand off Distance over Spherical Bodies in Hypersonic Flows
(2018-07-18)
One of the characteristics of the high speed ows over blunt bodies is the detached shock formed in front of the body. The distance of the shock from the stagnation point measured along the stagnation streamline is termed ...
Experimental Investigations of Leading Edge Bluntness in Shock Boundary Layer Interactions at Hypersonic Speeds
(2018-07-20)
Shock Boundary Layer Interactions (SBLIs) and shock-shock interactions are some of the most fundamental problems in high speed aerodynamics. These interactions are of particular importance in scramjet intakes at hypersonic ...
Ultrasonic Guided Wave Based Models, Devices and Methods for Integrated Structural Health Monitoring
(2018-01-31)
Structural Health Monitoring (SHM) systems for future structures and vehicles would involve a process of damage identification and prediction of certain quantities of interest that concerns the function and safety. This ...
