Abstract
Detonation engines have higher thermal efficiency than conventional engines. It is capable of shortening the combustor since the combustion process of detonation completes in quite a short time. Therefore, many researches on detonation engines have been conducted around the world. An RDE can be used as a kick rocket motor for deep-space exploration. However, there are some problems to be solved prior to the practical use of an RDE. One of the most critical problems is heat-transfer problem. High heat load in the combustor is expected. Thus, it is necessary to evaluate the heat-transfer characteristics of an RDE. To realize the space use of an RDE, we conducted long-duration combustion tests and vacuum tests. We succeed in 6-second and 10-second operations of an RDE using C/C composites. And from the vacuum tests, thrust performance is evaluated. We achieved 272 s of specific impulse under the low back pressure of 22.0 kPa.
