Dynamics And Stability Of A Launch Vehicle
(2011-07-08)
Stability is an important criterion in the design and performance of launch vehicles. Present day launch vehicles have become more and more flexible due to the constraints of weight reduction, necessarily imposed for ...
An Investigation of Architectures For Integration Of Stand-Alone INS And GPS Navigation Systems
(2009-07-08)
Inertial navigation systems (INSs) have the well-known advantages of being self-contained, weatherproof, jam-proof, and non-self-revealing while providing stable navigation information with little high-frequency noise. ...
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 ...
Breakup Behaviour Of Liquid Sheets Discharging From Gas Centered Swirl Coaxial Atomizers
(2011-04-06)
This thesis aims at studying the breakup of swirling liquid sheets discharging from the outer orifice of gas centered swirl coaxial atomizers. Such atomizers are considered as propellant injection systems for semi-cryogenic ...
Dynamic Response Of A Satellite With Flexible Appendages And Its Passive Control
(2010-11-25)
Most present day spacecrafts have large interconnected solar panels. The dynamic behavior of the spacecraft in orbit can be modeled as a free rigid mass with flexible elements attached to it. The natural frequencies of ...
Autonomous Landing Of Unmanned Aerial Vehicles
(2010-03-26)
In this thesis the problem of autonomous landing of an unmanned aerial vehicle named AE-2 is addressed. The guidance and control technique is developed and demonstrated through numerical simulation results. The complete ...
