Differential Evolution Based Interceptor Guidance Law
(2013-05-29)
Kinematics based guidance laws like the proportional navigation (PN) and many other linear optimal guidance laws perform well in near-collision course conditions. These have been studied thoroughly in the literature from ...
Momentum And Enthalpy Transfer In Packed Beds - Experimental Evaluation For Unsteady Inlet Temperature At High Reynolds Numbers
(2013-06-10)
Solid propellant gas generators that have high gas capacity are used for fast pressurization of inflatable devices or elastic shells. However, many applications such as control surface actuation, air bottle pressurization ...
Measurement Of Static Pressure Over Bodies In Hypersonic Shock Tunnel Using MEMS-Based Pressure Sensor Array
(2013-10-08)
Hypersonic flow is both fascinating and intriguing mainly because of presence of strong entropy and viscous interactions in the flow field. Notwithstanding the tremendous advancements in numerical modeling in the last ...
Experimental Study Of Plasma Actuator Characteristics And Optimization Of Configuration
(2013-06-26)
Plasma actuators are devices which function by creating a discharge in air at atmospheric conditions. These devices have been demonstrated to effectively delay flow separation and enhance the lift- drag characteristics of ...
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 ...
Active Vibration Control Synthesis Using Viscoelastic Damping Phenomena
(2011-07-12)
In this thesis, a new method is followed to design an active control system which imparts viscoelastic phenomenological damping in an elastic structure. Properties of a hypothetical viscoelastic system are used to design ...
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 ...
