Book excerpt: This work was conducted to define further the effects of propellant composition variables on the acceleration-induced burning rate augmentation of solid propellants. The rate augmentation at a given acceleration was found to be a nonlinear inverse function of the reference burning rate and not controlled by binder or catalyst type at a given reference rate. A nonaluminized propellant and a low rate double-base propellant exhibited strong transient rate augmentation due to surface pitting resulting from the retention of hot particles on the propellant surface.

This book was released on 1972 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: Instantaneous burning rate data for a polybutadiene acrylic acid propellant, containing 16 weight percent aluminum, were calculated from the pressure histories of a test motor with 96.77 sq cm of burning area and a 5.08-cm-thick propellant web. Additional acceleration tests were conducted with reduced propellant web thicknesses of 3.81, 2.54, and 1.27 cm. The metallic residue collected from the various web thickness tests was characterized by weight and shape and correlated with the instantaneous burning rate measurements. Rapid depressurization extinction tests were conducted in order that surface pitting characteristics due to localized increased burning rate could be correlated with the residue analysis and the instantaneous burning rate data. The acceleration-induced burning rate augmentation was strongly dependent on propellant distance burned, or burning time, and thus was transient in nature. The results from the extinction tests and the residue analyses indicate that the transient rate augmentation was highly dependent on local enhancement of the combustion zone heat feedback to the surface by the growth of molten residue particles on or just above the burning surface. The size, shape, and number density of molten residue particles, rather than the total residue weight, determined the acceleration-induced burning rate augmentation.

Download or read book Effects of Orientation of the Acceleration Vector on Burning-rate Augmentation written by G. Burton Northam and published by . This book was released on 1972 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: The functional dependence of acceleration-induced burning-rate augmentation on the magnitude and orientation of the acceleration vector was determined for an aluminized composite propellant by using a slab motor mounted at various angles on a centrifuge. The rate augmentation was strongly dependent on the orientation of the acceleration vector with respect to the burning propellant surface.

Book Synopsis An Investigation of Solid Propellant Combustion in Standard and High Acceleration Environments by : Michael Abraham
Download or read book An Investigation of Solid Propellant Combustion in Standard and High Acceleration Environments written by Michael Abraham and published by . This book was released on 1974 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nonmetallized double-base and composite propellant, metallized composite propellant, and ammonium perchlorate (AP)/binder sandwich combustion were studied in standard and high acceleration environments. Experimental techniques used were high speed motion pictures, tow-color schlieren, laser schlieren, and centrifuge mounted combustion bombs. It was found for double-base propellant that the temperature increased continuously from the surface into the visible flame. Acceleration induced burning rate augmentation occurred and resulted in elimination of the visible flame. Acceleration apparently modified the surface or subsurface zones. AP/binder sandwich combustion was also found to be acceleration sensitive with binder flow-AP interactions proposed as the mechanism. Composite propellants burned with local diffusion flames to pressures as slow as 100 psi. A comparison is made between AP/binder sandwich combustion and propellant combustion. (Author).

Book Synopsis A Study of the Burning Rates of Composite Solid Propellants in Acceleration Fields by : Edward John Sturm
Download or read book A Study of the Burning Rates of Composite Solid Propellants in Acceleration Fields written by Edward John Sturm and published by . This book was released on 1968 with total page 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: The average burning rates of a series of composite solid propellants were measured in acceleration fields up to 1000 G using a combustion bomb mounted on a centrifuge. The propellants were burned at constant pressures of 500, 1000, and 1500 psia. Specially prepared motors allowed the study of the effect of simultaneous erosive and acceleration induced burning rate increases. The burning rates of both the non-metallized and the majority of the metallized propellants were found to depend on acceleration. The effect of acceleration was found to depend on the basic burning rates of the propellants and the aluminum and oxidizer particle sizes and weight percentages. The burning rates of two very fast burning rate propellants were found to be essentially independent of acceleration. The erosion sensitivity of a propellant was found to decrease with increasing acceleration. A model was developed which successfully correlates the experimental results obtained for the non-metallized propellants. The experimental results for the metallized propellants could not be correlated by either of two models proposed by other investigators. This result indicates that a more complex model is required to explain the observed acceleration effects for metallized propellants. (Author).
