The study of path planning for a perpetual solar powered flight across regions around the world

The study of path planning for a perpetual solar powered flight across regions around the world / Tan Chin How
Penerbangan UAV jenis berkuasa tenaga solar tanpa berhenti di lokasi yang sama telah dicapai dalam kajian baru-baru ini. Jika kawasan liputan penerbangan UAV berkuasa solar tanpa berhenti bertukar kepada seluruh dunia bukan pada lokasi yang sama, ia boleh menjadi pseudolite, fungsi sebagai satelit komunikasi. Ia akan menjadi lebih murah dan lebih mudah dilancarkan oleh negara-negara masih di bawah pembangunan. Masalah berkalan kuasa merupakan faktor utama untuk mencapaikan pernebangan UAV tanpa berhenti. UAV berkuasa tenaga solar boleh mengumpul tenaga dari cahaya matahari pada waktu siang dan menyimpan tenaga yang berlebihan ke dalam bateri untuk penggunaan kuasa pada waktu malam. UAV boleh mencapai pernerbangan tanpa berhenti pada waktu malan adalah bergantung kepada kapasiti battery, jumlah tenaga berkumpul dan tenaga diguna pada waktu malam. Jumlah tenaga yang boleh dikumpulkan adalah bergantung kepada kekuatan sinaran matahari pada waktu siang. Dalam kajian baru-baru ini, banyak kajian mengenai UAV telah dilakukan untuk meningkatkan prestasi dari segi mempanjangkan masa pernerbangan. Manakala kajian tentang perancangan laluan UAV kebanyakan terhad kepada misi pengawasan, pengesanan sasaran dan perancangan laluan dengan autonomasi. Untuk mencapaikan matlamat pernerbangan tanpa berhenti, kekuatan sinaran matahari sepanjang laluan UAV hendaklah dipertimbangkan. Data kekuatan sinaran matahari, ketinggian permukanan bumi akan dikumpulkan dan masuk ke dalam perisian Matlab. Data data tersebut akan digunakan untiuk mentafsirkan kemungkinan mencapai pernebangan UAV tanpa berhenti. Status bateri akan dicatakkan dari semasa ke semasa sepanjang pernerbangan. Kawasan liputan UAV akan meliputi seluruh permukanan bumi. Keputusan kajian menunjukkan bahawa laluan A dan B menpunyai kemunkingan untuk mencapai pernerbangan UAV tanpa berhenti. Tetapi laluan A menpunyai risiko yang tinggi dan syarat yang ketat. Faktor faktor utama telah dibentangkan dan bahagian perbincangan dan berberapa cadangan telah dicadangkan. _______________________________________________________________________________________________________ Perpetual flight of solar power UAV on same location has been achieve in recent researches. If the perpetual flight of solar power UAV is change into worldwide instead on same location, it can be a pseudo-lite, function as a part of communication satellite. It will be cheaper and easier to launch for those countries still under development. In order to achieve the perpetual flight, the power supply play important role. Since it is solar powered UAV, it able to collect energy from sunlight during day time and store up the excessive energy into battery for the power consumption during night time. The amount of energy available in night time must sustain the flight, which are manipulated by the capacity of battery, total energy collected and energy consumption rate. The total energy collected is highly depend on intensity of solar radiance. In the recent researches, a lot of study on UAV has been done in order to increase the performance in term of endurance. Researches on path planning of UAV are available but limited to surveillance missions, target tracking and real time autonomous path planning. The data of worldwide solar radiance intensity for each hour is required in order to plan a delicate flight path and achieve perpetual flight. In this paper, the worldwide solar radiance intensity and digital elevation will be collected and used in Matlab programming software. Matlab programming software is used to identify the possibility of perpetual flight across region around the world. The battery status along the flight paths will identify and analyses. It also expected the UAV signal coverage will cover every region on earth. The path planning result shown that flight pattern A and B both have the possibility to achieve perpetual flight. But flight pattern A have higher risk and restriction than flight pattern B. The parameters with high impact have discussed in this thesis and recommended range are suggested.
