Numerical Study of an Innovative Aero-capture Technology using Electrodynamic force

我们进行了粒子模拟研究的可行性电动气动捕获。结果表明，高超声速稀薄再入流场在高空可以实现大幅度的电动增阻和热流降低。因此，电动力制动是可行的。从这个结果，我们研究了高度变化的电动力定量使用连续流模拟。结果表明，在低于82 km的高度，入地过程中会产生较大的电动力，而在较高的高度，由于雪崩电离的失活，电动力会消失。

We performed a particle simulation to investigate the feasibility of the electro-dynamic aero-capture. The results showed that the large electro-dynamic drag increase and heat flux reduction are achievable in hypersonic rarefied reentry flows at high altitudes. Therefore, the electro-dynamic braking is found to be feasible. From this result, we investigated the altitude variations of the electro-dynamic force quantitatively using continuum flow simulations. The results showed that large electro-dynamic force generates at altitudes lower than 82 km in earth entries, but the force will vanish at higher altitudes because of the deactivation of avalanche ionizations.
