Breakup Behaviour Of Liquid Sheets Discharging From Gas Centered Swirl Coaxial Atomizers
(2011-04-06)This thesis aims at studying the breakup of swirling liquid sheets discharging from the outer orifice of gas centered swirl coaxial atomizers. Such atomizers are considered as propellant injection systems for semi-cryogenic ... -
Efficient Trim In Helicopter Aeroelastic Analysis
(2011-04-06)Helicopter aeroelastic analysis is highly complex and multidisciplinary in nature; the flexibility of main rotor blades is coupled with aerodynamics, dynamics and control systems. A key component of an aeroelastic analysis ... -
Aeroelastic Analysis And Optimization Of Composite Helicopter Rotor With Uncertain Material Properties
(2011-04-06)Incorporating uncertainties in the aeroelastic analysis increases the confidence levels of computational predictions and reduces the need for validation with experimental or flight test data. Helicopter rotor blades, which ... -
Experimental Study Of Large Angle Blunt Cone With Telescopic Aerospike Flying At Hypersonic Mach Numbers
(2011-04-06)The emerging and competitive environment in the space technology requires the improvements in the capability of aerodynamic vehicles. This leads to the analysis in drag reduction of the vehicle along with the minimized ... -
Development Of Gyroless Attitude And Angular Rate Estimation For Satellites
(2011-04-06)Studies aimed at the development of indigenous low cost star tracker and gyroless attitude and angular rate estimation is presented in the thesis. This study is required for the realization of low cost micro satellites. A ... -
Experimental Investigations Of Aerothermodynamics Of A Scramjet Engine Configuration
(2011-04-06)The recent resurgence in hypersonics is centered around the development of SCRAMJET engine technology to power future hypersonic vehicles. Successful flight trials by Australian and American scientists have created interest ... -
Time Scale Separated Nonlinear Partial Integrated Guidance And Control Of Endo-Atmospheric Interceptors
(2011-03-17)To address the concern of classical guidance and control designs (where guidance and control loops are designed separately in an “outer loop – inner loop” structure), integrated guidance and control (IGC) ideas have been ... -
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 ... -
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, ...
