Mechanical and insulating connection between a nozzle and the filament- wound casing of the combustion chamber of a solid propellant rocket motor

摘要

The present invention relates to a mechanical and insulating connection between, on the one hand, a filament-wound casing, constituting a wall for the combustion chamber of a solid propellant rocket motor, and on the other hand, a hot nozzle made from a heat- conducting refractory material wherein said connection consists of a single connecting ring fixed to the nozzle and resiliently connected to the wound casing, which ring is made from a low density insulating material, resistant to mechanical forces, as well as to mechanical shocks and thermal stresses, preferably a composite material with multidirectional reinforcements and a ceramic matrix.
