Single-event, drag-modulated aerocapture has become a promising control scheme in the past decade. However, these architectures suffer from exhausted control authority post-jettison. Multiple drag-skirt jettison events have been shown to enhance aerocapture performance, yet still suffer from unidirectional control capabilities. An apoapsis target biasing method is introduced to improve multi-event, drag-modulated aerocapture accuracy and robustness. Entry trade studies and Monte Carlo methods are used for comparison to the state-of-the-art, assessing performance at 400 and 2000 km apoapsis targets and at entry flight path angles of $-5.4°$ and $-5.6°$. Two ballistic coefficient ratio sets are investigated for both two- and three-stage separation event architectures. A two-stage architecture equipped with the biasing method is shown to be capable of reducing mean apoapsis error to zero, while also showing standard deviation reductions in apoapsis error and circularization $\mathrm{\Delta }v$ by 64.1 and 74.8%, respectively, compared with the state-of-the-art. A biased, three-stage architecture is shown to provide further benefit, reducing apoapsis error standard deviation by 70% relative to an equivalent unbiased architecture and 10.16% relative to a similarly sized two-stage architecture.

在过去的十年中，单事件、阻力调制的气动捕获已成为一种很有前途的控制方案。然而，这些体系结构在抛弃后遭受用尽的控制权。多次拖曳裙式抛掷事件已被证明可以提高空中捕获性能，但仍然受到单向控制能力的影响。引入了远点目标偏置方法来提高多事件、阻力调制的空中​​捕获精度和鲁棒性。进入交易研究和蒙特卡罗方法用于与最先进的技术进行比较，评估 400 和 2000 公里远点目标以及进入飞行路径角为$-5.4°$ 和 $-5.6°$. 针对两级和三级分离事件体系结构研究了两个弹道系数比组。配备偏置方法的两阶段架构显示能够将平均远地点误差减少到零，同时还显示远地点误差和圆化的标准偏差减少$\mathrm{\Delta }v$与最先进的技术相比，分别提高了 64.1% 和 74.8%。有偏的三级架构显示出进一步的好处，相对于等效的无偏架构减少了 70% 的远点误差标准偏差，相对于类似大小的两级架构减少了 10.16%。
