Shock Tunnel Investigations On Hypersonic Separated Flows
(2009-08-11)Knowledge of flow separation is very essential for proper understanding of both external and internal aerothermodynamics of bodies. Because of unique flow features such as thick boundary layers, merged shock layers, strong ... -
Shocks, Shock-Boundary Layer Interaction, And Transonic Flutter
(2017-09-27)Transonic utter is an aeroelastic instability characterized by part-chord shocks over an airfoil and single mode oscillations leading to a drop in the utter boundary. We present a numerical study that examines the influence ... -
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 ... -
Some Experimental and Numerical Studies on Evaluation of Adhesive Bond Integrity of Composites Lap Shear Joints
(2018-03-02)Adhesive bonding which has been in use for long as a traditional joining method has gained ground in the last couple of decades due to the introduction of advanced composite materials into the aerospace industry. Bonded ... -
Spectral Methods for different classes of Partial Differential Equations
The thesis touches numerical solutions and wave propagation analysis using spectral methods for different classes of partial differential equations (PDEs) having applications in various fields. We address the solution of ... -
Speech Signal Classification Using Support Vector Machines
(2011-03-16)Hidden Markov Models (HMMs) are, undoubtedly, the most employed core technique for Automatic Speech Recognition (ASR). Nevertheless, we are still far from achieving high‐performance ASR systems. Some alternative approaches, ... -
Spontaneous Crack Propagation In Functionally Graded Materials
(2009-10-28)Functionally graded materials (FGMs) are composites that have continuously varying material properties, which eliminate undesirable stress concentrations that might otherwise occur in layered composites. The concept of ... -
Spray morphology and droplet characteristics in gas centered swirl coaxial (GCSC) atomizers
Studies on liquid atomization and spray formation in coaxial type atomizers are necessary to improve the performance of liquid propellant rocket engines. Recess ratio, expressed as the ratio of orifice recess length to ... -
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. ... -
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. ... -
