Flutter Susceptibility Assessment of Airplanes in Sub-critical Regime using Ameliorated Flutter Margin and Neural Network Based Methods
(2018-02-17)
As flight flutter testing on an airplane progresses to high dynamic pressures and high Mach number region, it becomes very difficult for engineers to predict the level of the remaining stability in a flutter-prone mode and ...
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 ...
Accurate and Efficient Algorithms for Star Sensor Based Micro-Satellite Attitude and Attitude Rate Estimation
(2018-04-18)
This dissertation addresses novel techniques in determining gyroless micro-satellite attitude and attitude rate. The main objective of this thesis is to explore the possibility of using commercially available low cost ...
Experimental Investigations on Supersonic Ejectors
(2018-04-13)
A supersonic ejector is used to pump a secondary gas using a supersonic primary gas flow by augmentation of momentum and energy in a variable area duct. The internal compressible flow through an ejector has many complex ...
A Computational Study of Structural and Thermo-Mechanical Behavior of Metallic Nanowires
(2018-04-11)
This thesis is an attempt to understand ways to improve thermo-mechanical and structural properties of nano-structured materials. A detailed study on computational design and analysis of metallic nanowires is carried out. ...
Optimal Trajectory Planning for Fixed-Wing Miniature Air Vehicles
(2018-04-02)
Applications such as urban surveillance, search and rescue, agricultural applications, military applications, etc., require miniature air vehicles (MAVs) to fly for a long time. But they have restricted flight duration due ...
Compressible Mixing of Dissimilar Gases
(2018-03-22)
This thesis is concerned with the study of parallel mixing of two dissimilar gases under compressible conditions in the confined environment. A number of numerical studies are reported in the literature for the compressible ...
Analysis and Detection of Ionospheric Depletions over the Indian Region in the Context of Satellite Navigation
(2018-04-18)
Satellites have revolutionized navigation by making it more universal, accessible and ac- curate. Global Positioning System (GPS) is the most widely used satellite navigation system in the world. However, it is prone to ...
Experiments on the Late Stages of Boundary Layer Transition
(2018-03-19)
In canonical boundary layer transition, a uniform laminar flow perturbed by 2-d T-S waves develops downstream into 3-d waves, which eventually break down with turbulent spots appearing. Previous experimental studies have ...
Linear Stability Models for Reacting Mixing Layers
(2018-03-12)
We develop a physics-based reduced-order model of the aero-acoustic sound sources in reacting mixing layers as a method for fast and accurate predictions of the radiated sound. Instabilities in low-speed mixing layers are ...
