OUTFITTED SOLID-PROPELLANT ROCKET ENGINE HOUSING Russian patent published in 2011 - IPC F02K9/34

Abstract RU 2418187 C1

FIELD: engines and pumps.

SUBSTANCE: outfitted housing comprises housing furnished with heat-resistant coat to accommodate channel charge partially attached to housing and tommed by elastic collars at its faces made from alternating layers of elastic materials and layers of elastic fabric. Collar tip is directed inside along charge channel of outfitted housing, secured with charge channel surface and provided with uniform taper toward its edge. Said taper on tip edge makes 0.1-0.5 of collar thickness while its length is selected from the condition set by mathematical expression protected by this invention.

EFFECT: ruling out ingress of propellant particles into collar space, higher reliability of outfitted housing.
