标题： Aerocapture Design Reference Missions for Solar System Exploration: from Venus to Neptune

摘要： 气动捕获技术是指利用行星大气层使航天器在一整圈内减速以实现几乎无燃料的轨道插入。自20世纪80年代以来，气动捕获已经得到了广泛研究，但尚未实际飞行过。在气动捕获过程中遇到的进入条件强烈依赖于目的地，而气动捕获提供的性能优势也取决于目的地。除了木星和土星（它们的极端进入条件使得气动捕获不可行）以外，气动捕获适用于所有拥有大气层的目的地。美国宇航局科学任务理事会最近的一项研究强调了制定基准设计参考任务的必要性，这可以作为系统级架构研究的起点。本研究使用气动捕获任务分析工具（AMAT）编制了金星、地球、火星、泰坦、天王星和海王星的设计参考任务列表。这些参考任务可以初步评估提议任务的气动捕获可行性，并为更详细系统的初步基准值提供依据。参考任务集为体系结构级研究提供了进入条件、控制需求和气动热载荷的快速估算。 显示英文摘要

摘要： Aerocapture is the technique of using planetary atmospheres to decelerate a spacecraft in a single pass to achieve nearly fuel-free orbit insertion. Aerocapture has been extensively studied since the 1980s but has never been flown yet. The entry conditions encountered during aerocapture are strongly destination dependent, and performance benefit offered by aerocapture is also destination dependent. Aerocapture is applicable to all atmosphere-bearing destinations with the exception of Jupiter and Saturn, whose extreme entry conditions make aerocapture infeasible. A recent study by the NASA Science Mission Directorate highlighted the need for baseline design reference missions, as a starting point for system level architecture studies. The present study uses the Aerocapture Mission Analysis Tool (AMAT) to compile a list of design reference missions at Venus, Earth, Mars, Titan, Uranus, and Neptune. These reference missions can provide an initial assessment of the feasibility of aerocapture for a proposed mission, and provide intial baseline values for more detailed system studies. The reference mission set provides a quick estimate of the entry conditions, control requirements, and aero-thermal loads for architectural level studies.
