S1901-1-3 小型ソーラーセイル実証機(IKAROS)のセイル展開ミッション(小型宇宙システム(1),社会変革を技術で廻す機械工学)

Abstract

Japan Aerospace Exploration Agency (JAXA) developed a small demonstrator of solar power sail orbiter to demonstrate solar sail technology that utilizes photons from the sun for continuous acceleration and electrical power generation by thin flexible solar arrays. The small demonstrator "Interplanetary Kite-craft Accelerated by Radiation Of the Sun (IKAROS)" was launched on May 21st 2010, and succeeded in deploying solar power sail on Jun 9th. In this paper, we introduce the deployment mechanism for solar power sail of IKAROS, and report on flight data of sail deployment mission in orbit.
