Fluid-Throat-Induced Shock Waves During the Ignition Transient of Solid Rockets
VR Sanal Kumar,Heuy Dong Kim,B. N. Raghunandan,A. Sameen,Toshiaki Setoguchi,Srinivasan Raghunathan +5 more
TL;DR: In this paper, the authors predict the ignition transient of a solid-propellant rocket motors with a nonuniform port, with sudden expansion and/or steep divergence/convergence or protrusions.
Journal ArticleDOI
Flame Spread with Sudden Expansions of Ports of Solid Propellant Rockets
TL;DR: In this article, it has been shown conclusively that under certain conditions of step location, step height, and port height, which govern the velocity of gases at the step by the partially ignited propellant surface or by the igniter gas Row, secondary ignition can occur far downstream of the step, This is very likely to be within the recirculating Row region.
Journal ArticleDOI
Prediction of Detonation Velocity and N−O Composition of High Energy C−H−N−O Explosives by Means of Artificial Neural Networks

Journal ArticleDOI
Thermoviscoelastic Characterization of a Composite Solid Propellant Using Tubular Test
TL;DR: In this paper, a more realistic experimental method was reported for the characterization of propellants at multiaxial stress conditions using a grain-pressurization test called the tubular test.
Journal ArticleDOI

TL;DR: In this paper, a closed-form analytical model is developed for estimating the 3D boundary-layer-displacement thickness of an internal flow system at the Sanal flow choking condition for adiabatic flows obeying the physics of compressible viscous fluids.
