Experimental solid rocket motor firings

摘要

FIELD: engines and pumps.;SUBSTANCE: proposed engine comprises housing made of composite with front and rear bottoms interconnected by cylindrical section, solid-propellant charge secured to housing and recessed nozzle. Reusable blank flange is mounted at front bottom with igniter arranged at outer side. Charge outer radius, charge channel radius, nozzle throat radius and housing structural shell cylindrical section thickness are defined by ratios protected by propose invention.;EFFECT: possibility to define specific thrust pulse and solid-propellant combustion rate at strained state.;1 dwg
