| 内容記述 | NASA and the Air Force Research Laboratory are involved in a Joint System Study (JSS) on Two-Stage-to-Orbit (TSTO) vehicles. The JSS will examine the performance, operability and uncertainty of unmanned, fully reusable, airbreathing-based TSTO launch vehicle concepts. NASA is providing a concept using turbine-based combined cycle (TBCC) propulsion on the booster stage and an all-rocket orbiter. The Air Force supplied two vehicle concepts, both utilizing an all-rocket booster; one with an all-rocket orbiter, the other using a rocket-based combined cycle orbiter. For NASA, this study is being used for tool assessment and development, and to identify generic technology gaps, not to choose vehicle types or concepts. This presentation starts with an overview of the major JSS ground rules and assumptions. Second, the NASA TSTO concept, Reusable Airbreathing Launch Vehicle - iteration B (RALV-B) is introduced, including its mission profile and, the vehicle (booster and orbiter) layout and packaging. The high speed propulsion concept is then briefly discussed, including the work performed and lessons learned. The low speed TBCC propulsion system is covered next in some detail. An overview for the low speed system is given; then its development is discussed (starting with initial layout and leading to more detailed analyses performed and results). The low speed system portion is wrapped up with lessons learned and summary. Finally, an overall summary and lessons learned so far for the JSS are given as well as work planned to complete the study. |
