Available in PDF, EPUB and Kindle. Book excerpt: This research program is designed to address the critical need for data on the gas phase chemistry of solid propellants through the development and application of a Microprobe Mass Spectrometer (MPMS) system. The MPMS systems is being used to study the gas-phase chemistry occurring above solid propellant ingredients and actual solid propellants when they are heated and/or ignited by the heat flux from a Carbon dioxide laser. Currently the MPMS system uses quartz microprobes with orifice sizes of twenty microns which results in a spatial resolution of approximately 100 microns. In addition to the MPMS system, direct and Schlieren photography are being used to study the flame structure and twenty-five micron thermocouples are being used to measure the gas-phase temperature profile. The specific goal of this research is to obtain detailed species profiles of the major reacting species above the surface of the individual propellant ingredients and actual propellants in order to obtain an improved understanding of the controlling chemical processes and of the interactions of binders and oxidizers in heterogeneous propellants. In the testing both heterogeneous and homogeneous propellants are being studied as well as their individual ingredients.

This book was released on 1991 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: This research program is designed to address the critical need for data on the gas-phase chemistry of solid propellants through the development and application of a microprobe mass spectrometer (MPMS) system. The MPMS system is being used to study the gas-phase chemistry occurring above solid propellant ingredients and actual solid propellants when they are heated and/or ignited by the heat flux from a CO2 laser. In addition to the MPMS system, direct and Schlieren photography are being used to study the flame structure and twenty- five micron thermocouples are being used to measure the gas-phase temperature profile. During the last year nearly fifty tests were performed with neat RDX as well as with composite, XM-39 and BLX-9, and double-base propellants, M-9 and JA-2. Measurements of gas-phase species and temperature profiles for neat RDX and tow RDX composite propellants show that while the chemical species detected are similar, the gas-phase structure for these propellants is significantly different. For incident laser energy fluxes above 100 W/sq cm, all three propellants exhibited a primary flame caused by the reaction of CH2O and NO2. The mole fraction of CH2O at or near the sample surface was approximately 0.20 for RDX and XM39 but was about 0.33 for BLX9 due to the addition of CH2O from the decomposition of the BTTN energetic plasticizer. The primary flame products consisted of significant amounts of NO for all three propellants and CO for the composites along with smaller amounts of H2O for RDX and BLX9, CO2 for RDX and XM39, and h2 for RDX.

Download or read book A Study of the Gas Phase Chemistry of Solid Propellants Using a Microprobe Mass Spectrometer (MPMS) System: Initial Development of the MPMS System written by and published by . This book was released on 1990 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: Detailed knowledge of the gas-phase reactions which occur during propellant ignition and combustion are required to understand and model these processes. If detailed models were available, modification of propellant formulations for improved combustion behavior could be achieved with much less trail-and-error testing. Furthermore, detailed models could be used to generate simplified kinetics schemes for use in propellant models. Without a firm basis for these simplified kinetic schemes, the kinetic parameters are often adjusted to fit burning rate and ignition data; thus the propellant models are reduced to sophisticated curve fits to experimental data. The present research program, centers around the development and application of a microprobe, mass spectrometer (MPMS) system to study the gas phase chemistry of solid propellant ingredients and solid propellants during heating by a CO2 laser and during steady combustion. The MPMS system uses quartz microprobes with orifice sizes of 100 microns or less to withdraw gases from the region above the sample material. Through a two stage pumping system, the sample is delivered to a quadrupole mass spectrometer for analysis. Sampling is continuous throughout the combustion event so that species profiles of stable intermediates above the sample are obtained during the experiments.

This book was released on 2012-12-06 with total page 756 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book represents a collection of lectures presented at the NATO Advanced study Institute(ASI) on "Chemistry & Physics of the Molecular Processes in Energetic Materials", held at Hotel Torre Normanna, Altavilla Milicia, Sicily, Italy, September 3 to 15, 1989. The institute was attended by seventy participants including twenty lecturers, drawn from thirteen countries. The purpose of the institute was to review the major ad vances made in recent years in the theoretical and experi mental aspects of explosives and propellants. In accordance with the format of the NATO ASI, it was arranged to have a relatively small number of speakers to present in depth, re view type lectures emphasizing the basic research aspects of the subject, over a two week period. Most of the speakers gave two lectures, each in excess of one hour with addition al time for discussions. The scope of the meeting was limit ed to molecular and spectroscopic studies since the hydro dynamic aspects of detonation and various performance crite ria of energetic materials are often covered adequately in other international meetings. An attempt was made to have a coherent presentation of various theoretical, computational and spectroscopic approaches to help a better understanding of energetic materials from a molecular point of view. The progress already made in these areas is such that structure property (e. g.
