Method of enhancing microthruster performance |
摘要 |
Coaxial micronozzles are disclosed. Embodiments of the present disclosure include coaxial micronozzles with center-body geometries to exploit pressure thrust. Some embodiemnts include a generally cylindrical centerbody extending through at least a portion of the flowpath and extending into the exit so as to form a generally annular throat, wherein the microthruster is adapted and configured such that the Reynolds number through the throat is less than about one thousand. Some embodiments show a potential threefold increase in specific impulse under vacuum and near vacuum conditions. |
