本計劃主要探討光在太空飛行中如何提供動力來源,尤其注重在光壓對於太空飛行的應用。目前太空航行器對於光的力用,主要來自於太陽能。太陽能必需先將光能轉換為電能,再將電能轉換為其它的能量。如此一來,不儘因為多次能量轉換而造成效率低落,而且推進的能量主要還是來自於傳統的化學燃料。最新的研究顯示,透過大面積的輕巧且反射性佳的的材質,可有效利用光壓來進行推進,稱之為太陽帆或光帆。本研究將以此為基礎,探討在太空中如何利用光能,包括可否將現行太陽能板和太陽帆等功能結合為單一元件,以減輕太空船所需攜帶重量;並將思考是否有新式的光能利用方式,使得未來透過光能,便能有效提供宇航飛行所需能量。透過本項計劃的探討,不儘有助於新式宇航動力的開發研究,而且可以使參與計劃的理學院學生,學習物理如何應用於工程之上;使參與計劃的工學院學生,學習諸如電磁學、光學、量子力學等基礎物理,以達成跨領域人才交流之目的。

This project mainly discusses the optical powered space travel, especially focuses on the application of optical pressure. The current state of utilizing optical energy concentrates on the solar panel, which provides the spacecraft with various kinds of energy by transforming the solar optical energy into electric energy. However, the efficiency is very low due to too many energy transformations. On the other hand, the thrust of the spacecraft cannot be provided by the solar energy directly. We still have to bring the conventional chemical fuels in order to produce thrust. The newest researches discuss how to make use of optical pressure for the production of thrust, named “solar sail”. This project, based on the researches of solar sail, is to investigate, but not limit to, the potential methodology that unifies “solar sail” and “solar cell”, which can reduce the weight of a spacecraft. Moreover, we are to investigate the potential new methods of utilizing optical energies, so that the spacecraft can be fully driven by optical energy. This project provides not only the opportunity of exploring new types of power for space travel, but, most important of all, the opportunity of developing cross-discipline talents – students with scientific background can touch how Physics is applied to engineering, while those with engineering background study the basic Physics, such as electromagnetism, optical physics, quantum mechanics and so on.

Keywords: Solar sail, Optical physics, Orbit Mechanics, Navigation, Guidance and Control, Avionics
