Additive Manufacturing of Inconel 718 Cellular Structures
Additive Manufacturing (AM) is getting adopted in various industries like automobile, aerospace, medical, nuclear, defense, and space, amongst many others, in the last five to ten years due to the tremendous advantages of ... -
Advanced Guidance Laws for Field-of-View and Impact Angle Constrained Engagements
This thesis deals with the development of guidance laws for interceptors with seeker field-of-view (FOV) and impact angle constraints. Two classes of guidance problems, namely, field-of- view and impact angle constrained ... -
Analysis of Kinematic Constraints in Fixed-Wing UAV Formation Flying
Rise in autonomy has led to increase in usage of Unmanned Aerial Vehicles (UAVs) for various applications and has allowed the UAVs to perform complex and hazardous missions with ease. Formation of multiple UAVs finds ... -
Automated Meshless CFD Process using Cartesian Point Distribution
The thesis deals with the meshless methods based on generalized finite difference procedure operating on the mere distribution of points. The work per se focuses on maturing the meshless LSFD-U solver as a standard industrial ... -
Blast Mitigation Strategies for Marine Sandwich Structures
Blast mitigation is being researched from the time of world war II. There were full field blast tests and analytical studies on the performance of monolithic structures to mitigate blast load. Sandwich structures were also ... -
Dynamics of Actuated and Interacting Swirl Premixed Flames in Model Gas Turbine Combustors
Lean premixed combustion is preferred in gas turbines because of the reduced (NOx) emissions. However, the combustors operating in lean premixed regime could suffer from problems like flame flashback, flame blowoff and ... -
Electric Field-Guided Alignment of Carbon Nanotubes in Polymer Matrix Composites for Structural Applications
Carbon nanotubes (CNTs) have been extensively researched for diverse applications in recent years. In the present work, the use of low frequency non-uniform alternating electric fields to manipulate the alignment behavior ... -
Evaluation of Hygrothermal Ageing In Cfrp Composite Material: A Study Using Non-destructive Techniques
Advanced composite materials are replacing conventional metals/alloys in aerospace industries due to their excellent strength and stiffness-to-density ratio as well as some other better physical and mechanical properties ... -
Explicit Filtering LES for turbulent premixed flames
Large eddy simulations of a premixed, turbulent, methane-air round jet flame at an equivalence ratio of 0.8 and unburnt gas temperature of 800 K are performed using Explicit Filtering LES (EFLES) method. The nominal inflow ... -
Interaction behavior and droplet characteristics of multi-injector sprays
The injector faceplate of a liquid propellant rocket engine is comprised of numerous single-element atomizers to inject propellants into the engine thrust chamber. The sprays from these single-element atomizers interact ... -
Optimal Numerical Integration Method for Higher Order Polygonal Finite Elements and its application in microstructure modeling
In conventional Finite Element Method (FEM), triangular and quadrilateral elements are commonly used finite elements and their counterparts with tetrahedral and hexahedral elements in three-dimensions to discretize the ... -
Real Time Solutions to Aerospace Optimal Control Problems
A real-time autonomous trajectory generation methodology for aerospace vehicles using pseudo-spectral based global collocation methods is presented in this thesis. The proposed method is formulated in a manner whereby ...
