A process for the preparation of a regenerative cooled nozzle expansion of a rocket combustion chamber and the nozzle expansion

摘要

A process for the preparation of a regenerative cooled nozzle expansion (100) of a rocket combustion chamber, which has a first wall (1) and a second wall (2), which are arranged coaxially relative to one another and between which a number of cooling channels (11) is formed by the cooling channel fins (5, 10) are laterally limited, in which the first and second wall (1, 2) by means of an interlocking connection (7) are connected to one another by cooling channel fins (5, 10) of the first wall (1) in corresponding depressions (6) of the second wall (2) for the formation of the positive connection (7) engage, characterised in that the positive engagement (7) by a deformation of the having the depressions, second wall (2) in the region of the cooling channels (11) is produced.
