LLE Review, Volume 106 83 Introduction Inertial confinement fusion (ICF) is an approach to fusion that relies on the inertia of the fuel mass to provide confinement. The confined fuel must reach a high temperature and density to produce enough D + T $ a(3.5 MeV) + n(14.1 MeV) reactions so that the total energy released is much larger than the driver energy required to compress the fuel. The cap...

This paper discusses a set of experiences I had in developing ROCKET, an early application generator in the area of rocket flight mechanics at the Rand Corporation. It begins by describing a precursor system I worked on at General Dynamics. It also covers some experiences with the interactive Graphic ROCKET followon, and POGO, an early GUI builder. It concludes by relating these to the recent M...

Perchlorate, an iodide uptake inhibitor, is increasingly being detected in new places and new matrices. Perchlorate contamination has been attributed largelyto the manufacture and use of ammonium perchlorate (the oxidizer in solid fuel rockets) and/or the earlier use of Chilean nitrate as fertilizer (approximately 0.1% perchlorate). However, there are regions such as the southern high plains (T...

We have recently introduced several important improvements in the measurement of distillation curves for complex fluids. The modifications provide for (1) a composition explicit data channel for each distillate fraction (for both qualitative and quantitative analysis), (2) temperature measurements that are true thermodynamic state points that can be modeled with an equation of state, (3) temper...

The Mineral and Mining industry is a huge energy requiring sector which demands connections to viable electric power origin reference. With the upsurge of these mineral requests decreasing valued grades ores, aspiration approximated sky-rocket 36% by year 2035. It even projected accelerate geometrically from fact that sophistication powering mine locations speeds up stability into necessity app...

an internal ballistics model has been developed for performance prediction of a solid propellant rocket motor. inthis model a 1-d unsteady euler equation with source terms is considered. the flow is assumed as a non-reacting mixture of perfect gases with space and time varying thermo physical properties. the governing equations in the combustion chamber are solved numerically by using the stege...

Paraffin wax has been identified as a hybrid rocket motor fuel, which offers enhanced regression rates and improved combustion performance. While various investigations into the performance of this class fuels are being conducted around world, consideration its structural is often overlooked. The research presented here establishes simplified, yet accurate method defining paraffin fuel grain to...

High-density fuel candidates have been synthesized in up to 90%yield from β-pinene, a renewable strained bicyclic compound derived fromwood and plant sources. The process is based on the heterogeneous acidic catalysts Montmorillonite-K10 and Nafion, which promote selective isomerization and dimerization of pinenes under moderate conditions (100 C and atmospheric pressure). Montmorillonite-K10 w...

The showerhead is the most common type of injector used in hybrid rocket motors due to its design and manufacture simplicity. main drawback showerheads (SH) relatively low performance terms combustion efficiency because poor atomization liquid oxidizer. This study investigates problem enrich technical literature by presenting detailed experimental data on injectors a series static firing tests ...
