摘要

長滯空太陽能無人飛行載具，主要被建造於具備長時間在高度十萬英呎以上飛行的無人機，就像在平流層中飛行的衛星，成為能夠搭載通訊設備的研究平台。為了使太陽能無人機達到長滯空的目的，結構設計上必須盡可能地降低重量，例如減重孔的設計等;飛機外型上則盡量保持流線型，藉以提升飛機的飛行效率。本研究選用3K碳纖維布、高密度保麗龍、航空夾板等單位重量極輕的材料，製作翼展三米及十米的太陽能無人機。運用複合材料製作機翼，使整體機翼進一步輕量化外，還能保持應有的強度，抵抗高空飛行時面臨的外界力量。實驗機透過Autopilot系統執行多次長滯空飛行任務，其中包含夜間飛行任務，已累積相當多的飛行資訊和大氣資料，對於日後十米太陽能無人機的試飛有極大的助益。

Solar powered High Altitude Long Endurance (HALE) UAV, which is designed to fly for days in high altitude, can carry the communication equipment, and research platforms for missions. In order to stay for days in the high attitude, it is crucial to reduce the structural weight as much as possible which maintains the necessary structure strength. Light weight material with high specific strength, such as carbon fiber composite material, high density Styrofoam and aviation plywood, has been extensively used for the wing construction. The streamline fairing has also been used in order to hence the aerodynamics efficiency. In development stage, two wings with different wingspan and construction method are made. The wing with three meters’ wingspan which is made by high density Styrofoam, is designed to continually fly for 24 hours. The second wing with ten meters’ wingspan which is made by carbon fiber composite and aviation plywood, is designed to continually fly for days. Some further works, such as gaining altitude to store energy and more advanced battery, could be done for the endurance of solar airplane. The commercial potential will be huge once these technologies are ready for HALE aircraft.
