论文摘要
围绕泰坦的起源和演变及其所在的土星系统的起源和演变的关键问题仍然是卡西尼 - 赫林格斯任务之后的关键问题。在人体关键位置进行的原位测量是解决这些问题的一种高度有效方法，本报告中提出的空中水平平台旨在使前所未有的通道通往泰坦的北面湖泊，从而了解碳氢化合物循环，这是对环境和表面上发生的化学过程的潜力。拟议的重量超过空气飞行和潜水的水生着陆航天器Astraeus，通过使用多体物理液结构互动（FSI）CFD CFD CFD CFD模拟，并用偶联的网状平滑剂的水平和元素（SPH）和有限的方法来支持这种条件的建模，该条件可以预期在Titan的地面湖泊上进行预期（FSI）。
Key questions surrounding the origin and evolution of Titan and the Saturnian system in which it resides remain following the Cassini-Huygens mission. In-situ measurements performed at key locations on the body are a highly effective way to address these questions, and the aerial-aquatic platform proposed in this report serves to deliver unprecedented access to Titan's northern surface lakes, allowing an understanding of the hydrocarbon cycle, the potential for habitability in the environment and the chemical processes that occur at the surface. The proposed heavier-than-air flight and plunge-diving aquatic landing spacecraft, ASTrAEUS, is supported by the modelling of the conditions which can be expected on Titan's surface lakes using multiphysics fluid-structure interaction (FSI) CFD simulations with a coupled meshfree smoothed-particle hydrodynamics (SPH) and finite element method (FEM) approach in LS-DYNA.
