The invention discloses a spacecraft plume guiding device suitable for takeoff of an extraterrestrial celestial body. A conical guiding device is designed on a takeoff platform under an uplifting main engine, so that plume can be prevented from being ejected to the takeoff platform and then rebounded to an engine, and the engine and the takeoff platform are protected from thermal corrosion; the heat-proof skin is made of a high-modulus carbon fiber material, so that invasion of high-temperature airflow can be blocked, and a heat-proof effect is achieved; a reinforcing frame is arranged below the heat-proof skin, so that the heat-proof skin 1 has enough rigidity and strength to resist the impact of plume; after a plume guiding device is additionally arranged on the takeoff platform, a large number of engine pneumatic ions are guided to the periphery through the plume guiding device, the effect on uplifting is greatly reduced, and therefore the take-off stability is improved.
本发明公开了一种适用于地外天体起飞的航天器羽流导流装置,在上升级主发动机正下方的起飞平台上设计圆锥形导流装置,可以避免羽流喷射到起飞平台后被其反弹到发动机,从而保护发动机及起飞平台的热蚀;防热蒙皮材料采用高模量碳纤维材料,能够阻挡高温气流的侵入,达到防热效果;防热蒙皮下方设置增强框架,使防热蒙皮1具有足够的刚度和强度抵抗羽流的冲击;在起飞平台上增加羽流导流装置后,大量的发动机气动离子经羽流导流装置的导向四周,大大降低了对上升级的作用,从而提升了起飞稳定性。
