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. ...
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 ...
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 ...
Guidance And Control Of Unmanned Airships For Waypoint Navigation In The Presence Of Wind
(Aerospace Engineering, 2012-07-25)
Airships are a specific class of Lighter-Than-Air (LTA) vehicles. These vehicles achieve lift mainly through buoyancy; the usually ellipsoidal shaped hull contains a lifting gas such as helium, which produces the required ...
Study Of The Surface Roughness Evolution In Fatigued 316L Stainless Steel
(Mechanical Engineering, 2012-07-25)
Fatigue is a critical design consideration in many aerospace structures. As improvements are sought in overall performance, maintenance requirements, and total service life of modern aircrafts, the demands for fatigue ...
Dynamic Mode Decomposition Of Detonation Waves
(Aerospace Engineering, 2012-07-25)
Dynamic mode decomposition is applied to study the self-excited fluctuations supported by transversely unstable detonations. The focus of this study is on the effect of forcing on the limit cycle solutions. Using DMD, only ...
Hygrothermally Stable Laminated Composites For Optimal Extension Twist Coupling In Closed Cell Configuration
(Aerospace Engineering, 2012-07-25)
An optimization routine utilizing the sequential quadratic programming method is used to develop laminates that are hygrothermally stable in flat-strip configuration and are optimal for extension twist coupling in closed ...
