A combustion chamber, in particular for a rocket drive, includes at least one jacket madeof a composite material with a ceramic matrix. The composite material contains a fibrous structure made of carbon-containing fibers, and the fibrous structure comprises layers of fibers that form a three-dimensional matrix.

Combustion chamber with internal jacket made of a ceramic composite material and process for manufacture

A combustion chamber, in particular for a rocket drive, comprises at least one jacket made of a composite material with a ceramic matrix. The composite material contains a fibrous structure made of carbon-containing fibers, and the fibrous structure comprises layers of fibers that form a three-dimensional matrix.

A combustion chamber structure ( ) comprising a plurality of cooling ducts ( ) extending in the longitudinal direction of the combustion chamber structure ( ), whereby the combustion chamber structure ( ) is rotationally symmetrical in relation to an axis ( ) and comprised of an outer structure ( ) and a base body ( ) of the combustion chamber. The base body comprises ribs ( ) preferably extending in the direction of the axis ( ). The ribs are arranged in the peripheral direction of the combustion chamber structure and at least one first cooling duct ( ) extends in the interior of the ribs.
