Burning Rate Enhancement Analysis of End-Burning Solid Propellant Grains Based on X-Ray Real-Time Radiography

Physically Based Simulation of Solid Objects' Burning

This paper presents a novel method for realistic simulation of solid objects’ burning. The temperature field is first constructed based on combustion theories. Then, a temperature field motivated interaction model (TFMI) is proposed to simulate the interactions between the fire and the objects during burning. In TFMI, the decomposition of the objects is modeled by improving the level set method...

On burning regimes and long duration X-ray bursts

Hydrogen and helium accreted onto a neutron star undergo thermonuclear burning. Explosive burning is observed as a type I X-ray burst. We describe the different burning regimes and focus on some of the current inconsistencies between theory and observations. Of special interest are the rare kinds of X-ray bursts such as carbon-fueled superbursts and helium-fueled intermediately long X-ray burst...

A novel technique for the continuous evaluation of a burning rate of solid rocket propellant by using IR thermography

In this study, a novel technique for evaluating continuously burning rate of cylindrical cores made of a solid homogeneous propellant is presented. The propellant core was placed in the tube made of pyrolytic graphite (pyrographite). The burning rate of the rocket propellant has been determined by monitoring the burning front/zone movement on the external surface of the pyrographite tube by usi...

High-pressure Burning Rate Studies of Solid Rocket Propellants

Increased rocket motor performance is a major driver in the development of solid rocket propellant formulations for chemical propulsion systems. The use of increased operating pressure is an option to improve performance potentially without the cost of reformulation. A technique has been developed to obtain burning rate data across a range of pressures from ambient to 345 MPa. The technique com...
