Available in PDF, EPUB and Kindle. Book excerpt: The arc image furnace is used widely for evaluating solid propellant ignition characteristics, but the applicability of such data to rocket motors is questionable. In arc image testing, radiation replaces the normal conductive and convective heating modes that exist in rocket motor ignition; radiation interacts with the propellant in a basically different way. Thus, for example, because radiation is absorbed in depth, the ignition delay is sensitive to propellant opacity. In addition, radiation can cause subsurface disruption of the propellant. A physical model is proposed in which incident radiation penetrates the propellant and is absorbed, causing thermal and photochemical decomposition and a temperature increase. Oxidative reactions start either in the gaseous boundary layer or on the surface and, by thermochemical action, lead to a flame. The system of differential equations for this complete model is complicated and has not been solved. However, an equivalent model of simpler character is solved, and an equation is produced for the ignition time delay as a function of radiation intensity, pressure, and physico-chemical properties. The qualitative behavior of experimental radiative ignition data reported by Beyer and Fishman and by Bastress is explained by this theory. (Author).

This book was released on 1980 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: The arc image furnace is a laboratory device which may be used to ignite rocket propellant, simulating the conditions of overall heat flux and pressure levels obtained in the rocket motor. Ignition in a motor is usually initiated by a pyrotechnic device which produces a heating effect mainly by conduction of heat by hot particles impinging on the propellant surface and convective heating from the hot gases flowing over the surface. There is only a small proportion of the heat transferred by radiation from the igniter products. In the arc image furnace, however, radiant heat is the means used for igniting the propellant. Thus it is not an absolute test of ignition delay, but it gives an indication of the delays which may be expected from a solid propellant. (Author).
