PATH MEMBER FOR HIGH-TEMPERATURE FLOW

摘要

FIELD: rocket engineering. SUBSTANCE: path comprises axisymmetric housing 1 provided with inner heat insulation 4 and thrust ribs 2 and 3 with conical thrust surface arranged on its end faces, heat accumulating reinforcement that is made up as a stack of disks 5 and 6 with polyhedral (e.g. tetrahedral) central openings, and erosion-resistant facing made up as split layers received in the openings. The sides of the layers facing the axis of the housing define the flowing portion of the path. The split erosion-resistant layers are plates that are in contact with each other. The top sides of all or some plates are provided with stops that are in a contact with the answered grooves made in the polyhedral openings of the heat accumulating disks. EFFECT: enhanced reliability.
