The invention discloses a multi-constraint parameter satellite stealth optimization configuration, and belongs to the field of satellite configuration design, the multi-constraint parameter satellite stealth optimization configuration is a drop-shaped stealth satellite configuration, and an external framework of the configuration is a drop-shaped structure formed by truss combination and mutual connection and fixation of triangular configuration parts. The top octagonal pyramid structure, the octagonal frustum structure, the octagonal pyramid structure and the rectangular pyramid structure in the structure are all truss structures; strong scattering is reduced to the maximum extent through the configuration, mirror reflection is reduced through the smooth structure, and therefore the stealth characteristic is excellent. RCS characteristics are very good and meet stealth requirements of stealth satellites; in a dangerous wave band, the RCS is below-10dB when the incident angle is within the range of +/-30 degrees of a nose cone; and the circumferential RCS value is as low as possible. A force bearing plate, a force bearing rod and a supporting rib plate are additionally arranged on the structure, so that the mechanical constraint is met, and the satellite structure has large enough rigidity, strength and stability. And the heater power and the heat dissipation device loading position are determined, so that the thermal constraint of the satellite is met.

    本发明公开了一种多约束参数卫星隐身优化构型,属于卫星构型设计领域,多约束参数卫星隐身优化构型是水滴形的隐身卫星构型,构型外部框架是桁架组合并用三角构型零件相互连接固定形成的水滴形结构,所述的构型中顶部八棱锥结构,八棱台结构,八棱锥结构,四棱锥结构均为桁架结构;构型最大程度的减少了强散射,光滑的结构得到减少了镜面反射,所以具有优良的隐身特性。RCS特性非常良好满足隐身卫星的隐身需求:在危险波段,入射角度在鼻锥±30°范围内RCS均在‑10dB以下。周向RCS值尽量低。结构上添加承力板,承力杆和支撑筋板从而满足力学约束:卫星结构有足够大的刚度和强度以及稳定性。确定加热器功率以及散热装置装载位置从而满足卫星的热学约束。
