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 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: Report developed under STTR contract for Topic AF06-T012. The demand for higher performance rocket motors at a reduced cost requires continuous improvements in understanding and controlling propellant combustion. Numerous examples are available where seemingly minor modifications and improvements to existing solid rocket systems have caused previously well performing motors to exhibit unexpected and at times near catastrophic behavior. It is far cheaper to design out problems than fix them during the development or production phases. Various combustion issues have never been modeled in a complete motor prediction model. What is being proposed here has never been successfully done and would greatly increase the design tools available to the motor design community. The overall goal of this innovation is to provide a multi-physics based computer code which will accurately predict the entire flight of aluminum particles from the propellant surface through the nozzle exit plane together with a prediction of the effective properties of the binder, ammonium perchlorate, and aluminum particles which together constitute a solid propellant.

This book was released on 1984 with total page 105 pages. Available in PDF, EPUB and Kindle. Book excerpt: A continuing investigation is being conducted to develop techniques which can be used to obtain quantitative data that can be used to relate solid rocket propellant composition and operating environment to the behavior of solid particulates within the grain port and exhaust nozzle. The techniques employed are high speed motion pictures of propellant strand burners and slab burners in a cross-flow environment, SEM analysis of post-fire residue (strand, slab, and motor), determination of D32 across the exhaust nozzle using measurements of scattered laser light, and holograms of burning propellant strands and slabs in a cross-flow environment. In addition, work has been initiated to develop automatic data retrieval methods for obtaining particle size distributions from holograms taken of the combustion of solid propellants. Actual particle size of burning aluminum particles were obtained in high speed motion pictures by using high intensity rear illumination of the burning propellants to eliminate the flame envelopes surrounding the burning particles. Measurements of diffractively scattered light were successfully made for determination of changes in D32 across a solid propellant rocket motor exhaust nozzle. However, to date, propellant composition and grain geometry have significantly limited the range of obtainable data. Two-dimensional motors have been successfully employed to obtain good quality holograms of propellant burned in a cross-flow environment. A Quantimet 720 has been used in an initial effort to obtain particle size distributions from a photograph taken of a reconstructed hologram.
