Parametric Analysis Of A Detonation-type Turbofan
(Aerospace Engineering, 2012-04-11)
A new type of turbofan which detonates a fuel-air mixture was theoretically found to perform better than a conventional turbofan. A continuous detonation process is described and considered inside the core of the turbofan. ...
Graph Theoretic Framework Based Cooperative Control And Estimation Of Multiple UAVS For Target Tracking
(Mechanical Engineering, 2012-07-25)
Designing the control technique for nonlinear dynamic systems is a significant challenge. Approaches to designing a nonlinear controller are studied and an extensive study on backstepping based technique is performed in ...
Feasibility Study Of T700 Rotorcraft Engine Rotor Supported By Hybrid Air Foil Bearings
(Mechanical Engineering, 2012-04-11)
A potential solution towards light weighted and simple structured turbomachinery lies in elimination of oil-lubrication system. These promising benefits of oil-free turbomachinery have demanded extensive research in the ...
Vehicle Suspension Optimization For Stochastic Inputs
(Mechanical Engineering, 2012-04-11)
In the present thesis, a simulation based numerical method has been proposed for optimization of vehicle suspension system for stochastic inputs from random road surface profiles. Road surfaces are classified in based upon ...
Buckling Analysis Of Thin Plates With Or Without A Hole Under Arbitrary Boundary Conditions Using The Galerkin Method
(Mechanical Engineering, 2012-04-11)
This thesis demonstrates how to find the critical buckling load value of thin plates with or without a hole under different boundary conditions using the Galerkin method. The use of symbolic software is essential due to ...
Investigation Of Instabilities Affecting Detonations: Improving The Resolution Using Block-structured Adaptive Mesh Refinement
(Aerospace Engineering, 2012-07-25)
The unstable nature of detonation waves is a result of the critical relationship between the hydrodynamic shock and the chemical reactions sustaining the shock. A perturbative analysis of the critical point is quite ...
Experimental And Numerical Investigation Of Mass Transfer In Microreactors
(Mechanical Engineering, 2012-07-25)
In this work, two types of microreactors for reactions have been studied, which were involving multiple fluid phases: liquid-liquid (immiscible liquids) phase and gas-liquid phase. Investigation of mass transfer within ...
Estimation Of Aircraft States And Wind Exposure In Aerial Refueling
(Aerospace Engineering, 2012-07-25)
When a tanker and receiver aircraft fly in tight formation in an aerial refueling operation, they are exposed to various sources of wind with varying magnitude and direction. The tanker and the receiver aircraft experience ...
Experimental Feasibility Study Of Radial Injection Cooling Of Three-pad Radial Air Foil Bearings
(Mechanical Engineering, 2012-07-25)
Air foil bearings use ambient air as a lubricant allowing environment-friendly operation. When they are designed, installed, and operated properly, air foil bearings are very cost effective and reliable solution to oil-free ...
Experimental/computational Analysis Of Active Cooling Of Stacked Device Using Multidimensional Configured Thermoelectric Modules
(Aerospace Engineering, 2012-07-25)
Stacked devices are currently used widely because of their smaller footprint and corresponding ability to accommodate heterogeneous devices such as memory and logic and enable a silicon efficiency greater than 100%. This ...
