The rocket is the only vehicle that launches the spacecraft in the space. The orientation of the spacecraft in precise position is so crucial. But, the motion of the rocket can be influenced by internal and external disturbances. Furthermore, the rocket is a multi-input and multi-output nonlinear system whose dynamics are unstable and poorly understood. Hence, attitude control of the rocket is ...

Liquid propellant rocket utilizes an engine that uses liquid as a propellant. In rockets, fuel and oxidizer are pumped into the combustion chamber, where they get mixed burned. hydrogen is mainly used fuel, oxygen oxidizer. Slosh can occur with propellants. acts tuned damper helps in reducing dynamic response of vehicle. baffles tanks intelligent control rules guidance system be to this. A pote...

This article reviews and summarizes recent work on flow-structural interaction in solid motors. This interaction is important because it can lead to rocket motor failure. In the first part of the document, an idealized model of the failure mechanism is developed to illustrate in simple terms how such an event can occur. In the second part of this article recently published numerical modeling wo...

Nuclear fission has been used as a reliable source for utility power in the United States for decades. Even in the 1940’s, long before the United States had a viable space program, the theoretical benefits of nuclear power as applied to space travel were being explored [Humble, et. al.]. These benefits include long-life operation and high performance, particularly in the form of vehicle power d...

This study presents an imaging-based deep learning tool to measure the fuel regression rate in a 2D slab burner experiment for hybrid rocket fuels. The is designed verify mechanistic models of reacting boundary layer combustion rockets by measurement rates. A DSLR camera with high intensity flash used capture images throughout burn and are then find calculate rate. U-net convolutional neural ne...

Title of dissertation: A FUNDAMENTAL STUDY OF BOUNDARY LAYER DIFFUSION FLAMES Ajay Vikram Singh, Doctor of Philosophy, 2015 Dissertation directed by: Professor Michael J. Gollner Department of Fire Protection Engineering Modeling the realistic burning behavior of condensed-phase fuels has remained out of reach, in part because of an inability to resolve complex interactions at the interface bet...
