Onboard Propellant Gauging For Spacecraft
(2009-08-04)
Estimation of the total mission life of a spacecraft is an important issue for the communication satellite industries. For accurate determination of the remaining mission life of the satellite it is essential to estimate ...
Spontaneous Crack Propagation In Functionally Graded Materials
(2009-10-28)
Functionally graded materials (FGMs) are composites that have continuously varying material properties, which eliminate undesirable stress concentrations that might otherwise occur in layered composites. The concept of ...
Mode-3 Asymptotic Analysis Around A Crack Embedded In A Ductile Functionally Graded Material
(2009-09-15)
Functionally graded materials (FGMs) are composites with continuous material property variations. The distinct interfaces between the reinforcement and the matrix in classical composites are potential damage initiation ...
A High-Resolution Procedure For Euler And Navier-Stokes Computations On Unstructured Grids
(Indian Institute of Science, 2006-07-20)
A finite-volume procedure, comprising a gradient-reconstruction technique and a multidimensional limiter, has been proposed for upwind algorithms on unstructured grids. The high-resolution strategy, with its inherent ...
Experimental Investigations Of Surface Interactions Of Shock Heated Gases On High Temperature Materials Using High Enthalpy Shock Tubes
(2009-05-12)
The re-entry space vehicles encounter high temperatures when they enter the earth atmosphere and the high temperature air in the shock layer around the body undergoes partial dissociation. Also, the gas molecules injected ...
Experimental And Theoretical Studies On Jet Acoustics
(Indian Institute of Science, 2006-12-14)
A systematic research on aeroacoustics conducted around the world for the last few decades has revealed various inherent characteristics of the jet noise radiation. However, a lot more needs to be done for the theoretical ...
NEW PERSPECTIVES FOR ANALYZING THE BREAKUP, ENVIRONMENT, EVOLUTION, COLLISION RISK AND REENTRY OF SPACE DEBRIS OBJECTS
(Indian Institute of Science, 2005-03-10)
In the space surrounding the earth there are two major regions where orbital debris causes
concern. They are the Low Earth Orbits (LEO) up to about 2000 km, and Geosynchronous Orbits (GEO) at an altitude of around 36000 ...
Intraseasonal Variability Of The Equatorial Indian Ocean Circulation
(Indian Institute Of Science, 2004-10)
Climatological winds over the equatorial Indian Ocean (EqlO) are westerly most of the year. Twice a year, in April-May ("spring") and October-December ("fall"), strong, sustained westerly winds generate eastward equatorial ...
Impact of Orography on the Simulation of Monsoon Climate in a General Circulation Model
(Indian Institute of Science, 2005-02-28)
Orography plays a major role in the general circulation and climate of the tropics. Although many works have been done on the impact of global orography on summer monsoon, the previous studies have examined the impact on ...
Analysis Of Coupled-Resonator Slow-Wave Structures For Traveling-Wave Tubes For Aerospace Applications
(2009-04-30)
Through continued innovation and growth, traveling wave tube amplifiers (TWTAs) remains the microwave power amplifiers of choice in a wide range of high power microwave and millimeter-wave applications specifically for ...
