To provide a conformational spacecraft capable of constituting an omnidirectional space antenna capable of achieving both light weight and shape accuracy of a thin film surface, observing radio waves arriving from all directions, and identifying radio weave sources present in various directions and distances with high resolution.SOLUTION: This conformation spacecraft is constructed by expanding expansion-type beam members and tension members around the spacecraft from the form of the spacecraft that stores a plurality of expansion-type beam members and a plurality of tension members. The expansion-type beam members expanded from the state of being installed in the spacecraft are arranged, in a plurality of rotation symmetry axes of a virtual polyhedron constructed with the rough center of the spacecraft set as an original point, at roughly equal distances in the direction of the rotation symmetry axes. The tension members support two places of the respective ends of a nearest expansion-type beam member with tensile force. The respective ends of the expansion-type beam member are simultaneously supported by three or more tension members.SELECTED DRAWING: Figure 1
【課題】軽量性と薄膜面の形状精度とを両立し、更に、全方位から到来する電波を観測し、且つ、様々な方向や距離にある電波源を高い分解能で識別可能な全方位型宇宙アンテナを構成することができる立体構造宇宙機を提供する。【解決手段】複数の展開式梁部材と、複数の張力部材とを収納する宇宙機の形態から、宇宙機の周囲に展開式梁部材と張力部材を展開して構成される立体構造宇宙機であって、展開式梁部材は、宇宙機に備えた状態から梁部材を展開するものであって、宇宙機の概中心を原点にして構成される仮想的な多面体の複数の回転対称軸において、回転対称軸の方向に略等距離で配置され、張力部材は、最も近い展開式梁部材の各端部の2か所を張力により支持し、展開式梁部材の各端部は、3つ以上の前記張力部材により同時に支持されることを特徴とする立体構造宇宙機。【選択図】図1
