Magnetohydrodynamic Aerobraking for Spacecraft Entry to Earth's Atmosphere

一艘从火星返回的宇宙飞船在进入地球大气层时将经历前所未有的空气动力加热。磁流体动力气动拦阻包括对以这种速度在航天器周围形成的等离子体施加强磁场，从理论上通过减少结构热负荷和实现不那么严重的飞行轨迹来保护航天器。该项目旨在对这项从深空返回地球的技术进行实验研究。它具有重要意义，因为它将评估一种管理进入行星的巨大热负荷的新机制。预期的结果和好处将是开发一种减少航天器温度的新技术，导致更安全、更高效和可能可重复使用的航天器。

A spaceship returning from Mars will undergo unprecedented aerodynamic heating as it enters Earth's atmosphere. Magnetohydroynamic aerobraking involves applying a strong magnetic field to the plasma which forms around the spacecraft at these speeds, theoretically protecting it by reducing structural heat loads and enabling less severe flight trajectories. This project aims to experimentally study this technology for Earth return from deep space. It is significant because it will evaluate a new mechanism for managing the tremendous heat loads of planetary entry. The expected outcome and benefit will be development of a new technology to reduce spacecraft heating, leading to safer, more efficient, and potentially reusable spacecraft.
