The invention provides a variable configuration spacecraft system and method for non-cooperative target capture, and belongs to the field of deep space exploration, and the method comprises the following steps: 1) a rigid body assembly flies to the vicinity of a target; (2) the combination body spins and unfolds to form an annular belt; (3) enveloping a target outside the annular belt; and 4) encircling the target by the girdle. Large space debris and small celestial bodies belong to non-cooperative targets, a special interface for assisting capture cannot be provided, a general control mechanism and method are developed to realize reliable capture and stable connection of various targets, and the difficulty is great. In order to solve the problem, a plurality of controllable satellites which are connected into length-controllable ropes are unfolded to form an annular multi-body tethered satellite formation system, and the annular multi-body tethered satellite formation system captures non-cooperative targets which are large in size, complex in geometric shape and large in motion state and inertia information uncertainty after carrying out annular belt enveloping on the non-cooperative targets according to a preset track and then encircling the ropes. The system has the advantages of high applicability, high flexibility, high intelligence, reusability, small size and the like.
本发明提供了一种面向非合作目标捕获的变构型航天器系统及方法,属于深空探测领域,所述方法包含以下步骤:1)刚体组合体飞行至目标附近;2)组合体自旋展开为环带;3)环带外包络目标;4)环带合围目标。大型空间碎片和小天体均属于非合作目标,无法提供用于辅助捕获的专用接口,发展通用操控机构和方法实现对各类目标的可靠捕获与稳定连接,难度极大。为了解决该问题,本发明利用星间连接为可控长度绳索的多颗可控卫星展开形成环状多体绳系卫星编队系统,按预定轨迹对大尺度、几何外形复杂、运动状态及惯性信息具有较大不确定性的非合作目标开展环带包络后合围绳索实现捕获。具有适用性高、灵活性及智能性高、可重复使用和体积小等优点。
