Combustion chamber for use in e.g. expansion cycle rocket engine, has wall structure with set of tooth gaps interposed between spaced crown-wheels, and heat transfer increasing units arranged in tooth gaps and including chevron structure

摘要

The chamber (12) has an inner wall structure (10) with a set of tooth gaps (18) interposed between spaced crown-wheels (16), where the structure is formed of tubes (14) that are connected with each other. The tubes are formed of a single piece and are oriented parallel to a hot gas flow region. Heat transfer increasing units having a chevron structure (20) are arranged in the tooth gaps, where the structure (20) has a front edge oriented in a direction parallel to the region.
