Standoff Target Tracking Guidance using Line-of-Sight Distance Bifurcation
Unmanned aerial vehicle (UAV) applications that continue to receive significant attention are target acquisition and tracking. There exist many paths to track a stationary target from a prescribed altitude. The most widely ... -
Strength Prediction And Fatigue De-Bond Growth In Bonded Joints In Metallic And Composite Structures
(2013-05-23)Large scale structures such as those in aerospace flight vehicles are made in parts and assembled. Joints are inevitable in these systems and they are potential threats to the structural integrity of the flight vehicles. ... -
Stress-Assisted Pitting Corrosion Studies in Metallic Structures Using Advanced Modeling Methodologies
Pitting corrosion poses a significant threat to deepwater oil and gas production facilities, yet our current understanding of its impact on specific systems such as steel catenary riser (SCR), tensioned leg platforms (TLP), ... -
Structural Health Monitoring Of Composite Helicopter Rotor Blades
(Indian Institute of Science, 2007-04-18)Helicopter rotor system operates in a highly dynamic and unsteady aerodynamic environment leading to severe vibratory loads on the rotor system. Repeated exposure to these severe loading conditions can induce damage in the ... -
Structural Health Monitoring Of Composite Structures Using Magnetostrictive Sensors And Actuators
(2009-07-14)Fiber reinforced composite materials are widely used in aerospace, mechanical, civil and other industries because of their high strength-to-weight and stiffness-to-weight ratios. However, composite structures are highly ... -
Structural Health Monitoring Of Thin Plate Like Structures Using Active And Passive Wave Based Methods
(2013-07-03)Aerospace structures comprising of metals and composites are exposed to extreme loading and environmental conditions which necessitates regular inspection and maintenance to verify and monitor overall structural integrity. ... -
Structural Health Monitoring with Laser Doppler Imaging of Ultrasonic Guided Waves
This thesis deals with ultrasonic guided wave based non-destructive inspection and health monitoring of aircraft structural components using a non-contact sensing scheme based on laser Doppler scanning imaging technique. ... -
Structural Modeling And Analysis Of Insect Scale Flapping Wing
(2013-06-04)Micro Air Vehicles (MAVs) are defined as a class of vehicles with their larger dimension not exceeding 15 cm and weighing 100 gm. The three main approaches for providing lift for such vehicles are through fixed, rotating ... -
Structural Modeling and Damage Detection in a Non-Deterministic Framework
(2018-05-08)Composite structures are extremely useful for aerospace, automotive, marine and civil applications due to their very high specific structural properties. These structures are subjected to severe dynamic loading in their ... -
Structural sensitivity of the precessing vortex core instability in swirled jets
This thesis performs an LES study of the flow through a swirling nozzle. The nozzle has one single stream with swirl being generated by vanes mounted on an axially aligned centrebody. The end face of the centrebody ... -
Structure Of Sink Flow Boundary Layers
(2011-03-17)The work reported in this thesis is an experimental and theoretical investigation of the so-called sink flow boundary layers. These are two-dimensional (in the mean), favourable-pressure-gradient (FPG) boundary layer flows ... -
Structure of Turbulent, Swirling Round Jets
The present study deals with the numerical analysis of the effect of the swirl in the self-preservation region of the turbulent round jet. However, a large number of literature exists for the analysis of near-exit regions—very ... -
Studies On Impinging-Jet Atomizers
(2009-05-06)Characteristics of impinging-jet atomizers in the context of application in liquid propulsion systems are studied in this thesis. A review of past studies on impinging jets revealed the necessity of a correlation in terms ... -
Studies on Non-Destructive Evaluation of Friction Stir Weld Discontinuities with Probability of Detection
Friction stir welding(FSW) is a solid-state metal joining process which is currently being considered for joining of aerospace components. The zones associated with FSW are distinctly different from the fusion weld and ... -
Studies On Shock Wave Attenuation In Liquids
(2013-06-11)The attenuation mechanism of shock waves of arbitrary strength propagating in air has been reasonably well understood. On the other hand, very little is known about the precise mechanism of shock wave attenuation and energy ... -
Studies On The Combustion And Gasification Of Concentrated Distillery Effluent
(Indian Institute of Science, 2007-04-24)The need for effective disposal of huge volumes of industrial waste is becoming more challenging due to expected imposition of stringent pollution control regulations in the near future. Thermochemical conversion, particularly ...
