This book was released on 1986 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of aluminum combustion in pure oxygen and mixture (N2-H2- Cl2-O2) at high temperatures and pressures provides a simulation of combustion mechanism study of aluminum powder in solid rocket propellant. Computations were performed for predicting possible intermediate species and products. Emission spectra of important intermediate species were identified by using a spectrometer. Time histories of the AlO emission band show the continuum radiation of Al2O2 in the reaction scheme. The solid and liquid products were observed and analyzed by electron diffraction, X ray diffraction, transmission and scanning electron microscopes. The gaseous products were detected by using infrared spectrometry. These measurements are in good agreement with the computations and provide useful chemical kinetic data. Keywords: Mathematical prediction, Aluminized propellants, Aluminum oxides. (Chinese translations).

This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ammonium perchlorate's burning rate as a function of pressure has an exponent break around 4000 psi where the pressure exponent becomes greater than 1. This causes AP to be highly sensitive to pressure fluctuations that can damage or destroy ammonium perchlorate composite propellant-based solid rocket motors. Studies conducted on AP at these high pressure are few and there is a lack of direct qualitative data due to the challenges posed by the high-pressure environment and optical window structural limitations. This has left the cause exponent break mechanism unknown and difficult to study. The High-Pressure Combustion Lab has built an Ultra-High Pressure Optical Chamber (UHPOC) that allows for optical measurements at these higher pressure regimes. Testing visual measurement techniques using the UHPOC and a telescope zoom lens to take detailed images of the propellant surface during the burn was conducted. Non-aluminized propellant and aluminized propellant samples were tested to observe the mechanisms of aluminum particle combustion in a propellant at high pressures and the behavior of the propellant past the exponent break region. \par At atmospheric, detailed high-speed images on the propellant surface were obtained using a high-powered lamp to light the surface brighter than the flame. At higher pressures, however, the luminosity of the flame was significantly greater than the lamp, creating shadow images of the propellant. Binder agglomerates were observed coming off the surface which increased in size and magnitude as the pressure increased. This is attributed to AP decomposition becoming the dominant burning rate mechanism which burned faster than the surrounding binder as has been observed from previous studies and numerical models. This leaves the binder only partially pyrolyzed, forming the agglomerates which detached from the surface. Aluminum particles were found to ignite at all pressures with the binder agglomerating the same amount in both aluminized and non-aluminized samples. Atmospheric tests show aluminum particles with detached flames and high-pressure tests show aluminum particles with surface flames.

Available in PDF, EPUB and Kindle. Book excerpt: The usefulness of powdered aluminum as a propellant ingredient is compromised by the details of its behavior in the combustion zone, its combustion in the motor volume, and by the nature of the product oxide droplets. This project was aimed at clarification of the mechanisms governing concentration, sintering and agglomeration of aluminum on the propellant burning surface, subsequent combustion of agglomerated aluminum, and resulting size distribution of the A1203 product droplets. The approach was to study the response of individual propellant ingredients, and combinations, to controlled heating in laboratory experiments such as hot stage microscope and hot plate apparatus.

This book was released on 2020-08-21 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite significant developments and widespread theoretical and practical interest in the area of Solid-Propellant Nonsteady Combustion for the last fifty years, a comprehensive and authoritative text on the subject has not been available. Theory of Solid-Propellant Nonsteady Combustion fills this gap by summarizing theoretical approaches to the problem within the framework of the Zeldovich-Novozhilov (ZN-) theory. This book contains equations governing unsteady combustion and applies them systematically to a wide range of problems of practical interest. Theory conclusions are validated, as much as possible, against available experimental data. Theory of Solid-Propellant Nonsteady Combustion provides an accurate up-to-date account and perspectives on the subject and is also accompanied by a website hosting solutions to problems in the book.

Download or read book The Effect of Solid Propellant Binder on the Formation and Evolution of Aluminum Combustion Products written by and published by . This book was released on 1996 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: Novel particle collection and high speed photography techniques have been used to study the combustion behavior of an inert binder (IB) propellant and an energetic binder (EB) propellant. Both contained 18% aluminum and 37% coarse AP in order to provide very similar geometrical structures, and both propellants had essentially common burning rates. The aluminum combustion efficiency is higher and the characteristic agglomerate size is significantly smaller for the EB propellant than for the IB propellant (at 43 atm the agglomerate size, D43, was 190 micrometers for the EB propellant and 670 micrometers for the IB propellant). At 7.5 atm the characteristic roughness of the burning surface is about 300 micrometers for the EB propellant and about 800 micrometers for the IB propellant. X-ray photography and visual observations of quenching particles show that similar sized agglomerates can differ significantly in structure and aluminum content, and there is some indication of internal voids (i.e. low density). This appears to be a result of the different initial conditions that the agglomerates are exposed to when they initially form at the surface. The size distribution of fine oxide particles was not dependent on either pressure or the propellant binder (or on the size of agglomerates). The fine particle mass size distribution (i.e. the smoke) was observed to have 3 modal sizes, approx. 1, 3.5, and 7 micrometers.
