Segmented carbon-carbon exit cone assembly

摘要

An exit cone (10) for solid propellant rocket motors or liquid propellant rocket engines is fabri­cated as discrete carbon-carbon segments (12) and subsequently assembled into a cone. Preferably, longitudinal and circumferential supporting stiff­eners (32,34,44) are formed integrally therewith. This segmented construction means that if one part of the cone is flawed or damaged, it is necessary only to replace that part rather than the whole one.
