面向航天器在軌加注的地面模擬技術(shù)

Ground simulation technology for spacecraft on-orbit refueling

摘要: 文章結(jié)合近年來航天器在軌加注的相關(guān)研究，著重對其地面模擬試驗技術(shù)進行了探討。首先對國外相關(guān)地面模擬技術(shù)進行了綜述，其次對一種新型地面模擬系統(tǒng)進行了詳細介紹。該系統(tǒng)由氣浮平臺、航天器模擬器、光學(xué)測量系統(tǒng)、地面控制系統(tǒng)、自主對接和流體加注機構(gòu)等組成，不僅能演示航天器在軌加注任務(wù)的全過程，而且能完整演示自主對接與分離、流體傳輸與控制、導(dǎo)引測量與推進等在軌加注關(guān)鍵技術(shù)。

Abstract: Based on the studies of spacecraft on-orbit refueling, this paper discusses the ground simulation of spacecraft on-orbit refueling. The simulation systems developed in other countries are reviewed, with a special emphasis on a new ground simulation system. This system is mainly composed of a polished granite test bed, spacecraft simulators, video guidance system, control system on the ground, autonomous docking mechanism, and fluid transferring mechanism. It can not only demonstrate the whole experimentation process, but can also test the key technologies of on-orbit refueling, autonomous docking and separation, fluid transferring and controlling, and video guidance and thrust.
