本研究針對立方衛星增阻離軌技術的研發與驗證，核心目標是開發可控式阻力帆酬載之機械設計、分析、製作與測試，其目標是開發一套具備創新性與實用性的增阻裝置，並在立方衛星的應用上進行技術驗證。在本機構發展的過程中，三項核心要素被視為最重要的突破方向：可捲收材料管杆（Boom）的研製、管杆展開機構的開發與驗證、阻力帆的摺疊收納與展開技術，這三大核心技術將直接決定增阻離軌機構的性能表現、可靠度與能否實際應用於衛星任務。管杆是阻力帆的支撐骨架，必須具備輕量化、可捲收性。由於立方衛星本體的體積有限，須將長度可觀的管杆壓縮並有效收納，管杆必須能夠在捲收狀態下長時間保存，並於展開時迅速恢復至設計形狀，且展開後的管桿需提供足夠剛性，支撐阻力帆的展開，避免帆膜因抖動或結構不穩而影響脫軌效率，展開機構是保證管杆能夠從收納狀態轉換至完整展開狀態的核心元件，該機構需要同時滿足輕量化、可靠性與展開穩定性的需求，在太空環境下透過馬達驅動來完成。在研究過程中，通過Ansys軟體進行了一系列的模態分析以及隨機振動分析，以預測其在動態環境下的結構行為與自然頻率分布，阻力帆的設計是影響整體增阻效果的最直接因素，本研究選擇使用輕量化、耐高溫與抗輻射的薄膜材料，確保帆膜能在低地軌道中長時間維持結構穩定，在收納階段，阻力帆需能以捲收方式至最小體積，以便安裝在立方衛星有限的空間內，展開過程需平穩、對稱且可預測，本研究最終結果，是透過模擬分析與實驗數據的交互驗證，確認材料管在立方衛星中應用於增阻離軌裝置，以及承載額外酬載時的可行性與效能。此成果將能為未來立方衛星的設計方向與離軌技術的發展提供具體而有效的技術依據，同時也可望在減緩並解決日益嚴重的太空碎片問題上發揮關鍵作用，進一步推動太空科技往永續發展的目標邁進。

This study focuses on the development and verification of a drag deorbit system for CubeSats. The research aims to design, analyze, manufacture, and test a controllable drag sail payload for satellite deorbit applications. The three key technologies include rollable boom structures, boom deployment mechanisms, and drag sail folding and deployment systems, which directly influence the reliability and performance of the deorbit device.
The boom structure must provide lightweight characteristics, compact stowage capability, and sufficient stiffness after deployment. A motor-driven deployment mechanism was developed to achieve stable deployment under space conditions. Structural analyses, including quasi-static acceleration, modal, and random vibration analyses, were performed using ANSYS to evaluate structural performance.
Lightweight and durable membrane materials were selected for the drag sail to ensure stability in low Earth orbit while maintaining compact folding and reliable deployment capability.
The results from simulations and experiments confirmed the feasibility of applying rollable boom structures to CubeSat drag deorbit systems. This research provides useful references for future CubeSat deorbit technologies and contributes to reducing space debris and promoting sustainable space development.
