| 摘要: |
| 残骸落区的选择是在运载火箭构型设计时必须首要考虑的设计因素，其设计结果直接关系到落区内人民生命财产安全,因此残骸落区必须避开人口稠密、重要设施区域。然而运载火箭残骸的被动段轨迹与上升段轨道设计直接相关，过近或过远的落区都将影响火箭上升段轨道的设计结果，进而影响运载火箭的运载能力。本文以典型二级火箭论证为例，开展了基于落区约束火箭构型的总体方案优化，运载能力变化充分说明残骸落区对火箭构型论证的影响，为后续构型论证工作的高效开展夯实了基础。 |

| Abstract: |
| The selection of impact area is a primary factor that must be considered when developing launch vehicles.Populous area and important facilities must be avoided.However, the post-boost passive trajectory directly relates to the design of ascent phase.Inappropriate impact areas may lead to ascent flight departure from optimal design and at the cost of launch capacity loss.In this paper, a typical two-stage launch vehicle configuration is taken as an example, developing launch vehicle configuration optimization in constrained impact area.The change of capacity shows debris impact area on launch vehicle configuration influence, and this builds a solid foundation for subsequent works with high efficiency. |
