Piezoceramic Dynamic Hysteresis Effects On Helicopter Vibration Control Using Multiple Trailing-Edge Flaps
(2009-07-14)
Helicopters suffer from severe vibration levels compared to fixed-wing aircraft. The main source of vibration in a helicopter is the main rotor which operates in a highly unsteady aerodynamic environment. Active vibration ...
Weighted Least Squares Kinetic Upwind Method Using Eigendirections (WLSKUM-ED)
(2009-06-24)
Least Squares Kinetic Upwind Method (LSKUM), a grid free method based on kinetic
schemes has been gaining popularity over the conventional CFD methods for computation
of inviscid and viscous compressible flows past complex ...
Shock Tunnel Investigations On Hypersonic Separated Flows
(2009-08-11)
Knowledge of flow separation is very essential for proper understanding of both external and internal aerothermodynamics of bodies. Because of unique flow features such as thick boundary layers, merged shock layers, strong ...
Super-Convergent Finite Elements For Analysis Of Higher Order Laminated Composite Beams
(2009-08-12)
Advances in the design and manufacturing technologies have greatly enhanced the utility of fiber reinforced composite materials in aircraft, helicopter and space-
craft structural components. The special characteristics ...
Aerodynamic Analysis Of Grid Fins Using Analytical And Computational Methods
(2009-07-16)
Grid fins (lattice fins) are used as a lifting and control surface for highly manoeuvrable missiles. Grid fins also find their applications for air-launched submunitions. The main advantages are its low hinge moment ...
Combustion Instability Screech In Gas Turbine Afterburner
(2009-08-04)
Gas turbine reheat thrust augmenters known as afterburners are used to provide additional thrust during emergencies, take off, combat, and in supersonic flight of high-performance aircrafts. During the course of reheat ...
An Anti-Skid Brake Controller For A Fighter Aircraft With An Elastic Strut
(2009-04-29)
This thesis deals with the design of an anti-skid brake controller for a generic fighter aircraft. Antiskid brake controllers prevent wheel locking and maximize the coefficient of friction between the tyre and the ground, ...
Studies On Impinging-Jet Atomizers
(2009-05-06)
Characteristics of impinging-jet atomizers in the context of application in liquid propulsion systems are studied in this thesis. A review of past studies on impinging jets revealed the necessity of a correlation in terms ...
Linear Instability Of Laterally Strained Constant Pressure Boundary Layer Flows
(Indian Institute of Science, 2007-03-26)
The linear instability of laterally diverging/converging flows is an important aspect towards understanding the laminar-transition process in many viscous flows. In this work the linear instability of constant pressure ...
Analysis Of Multiply-Connected Acoustic Filters with Application To Design Of Combination Mufflers And Underwater Noise Control Linings
(2008-10-01)
This thesis endeavors towards developing various concepts employed in analysis and
design of acoustic filters for varied applications ranging from combination mufflers for automobiles to complex networks of gas carrying ...
