Progress of Actively Cooled Ceramic Matrix Composites Applied in Advanced Propulsion Systems
摘要
Abstract
Actively cooled ceramic matrix composite technology is a novel thermal management concept for advanced propulsion systems e. G. Scramjet engine, cryogenic rocket engine and gas turbine engine etc. . Combining both advantages of refractory materials and cooling structures, the concept is able to meet high performance goals at improving operating temperature margin, lower weight, increasing payloads and range, which is identified as a key technology for enabling reliable and low-cost space access. Through the collaborative efforts between US and Europe, this technology development is undergoing the transition from theoretical research and sub-scale investigation to full scale components fabrication for ground tests. In this concept,the integrated design that all CMC structure with built-in regenerative cooling channels or effusion holes by innovative preforming techniques are more efficient and feasible, thus is regarded as the most promising one for future propulsion system applications.关键词
