PERANCANGAN DAN PEMBUATAN PLATFORM UAV KOLIBRI-08V2 ENGINE THUNDER TIGER 46 PRO DENGAN SISTEM RADIO CONTROL Bagus Pratomo 08050011 ABSTRAK Pesawat UAV merupakan pesawat tanpa awak yang dibuat berasarkan pengembangan dari pesawat model radio control yang diberi berbagai sistem yang disesuaikan dengan misi pesawat tersebut, dalam penelitian ini, akan dilakukan perancangan Platform UAV dengan tujuan untuk menjadikan platform ini sebagai media pengembangan sistem UAV di lingkungan perguruan tinggi khususnya di Sekolah Tinggi Teknologi Adisutjipto (STTA). Tahapan perancangan pesawat ada 3 yaitu conseptual design, preliminary design,dan detail design. Dalam tulisan ini lebih di tekankan pada tahap conceptual design. Tahap conceptual design platform UAV Kolibri-08v2 ini yaitu dimulai dari penentuan maximum take-off weight pesawat, berat fuel yang digunakan selama penerbangan, geometri sizing, penggambaran model 3 dimensi pesawat dengan software CATIA V5R18, proses pembuatan pesawat, dan melakukan pengujian terbang. Data pesawat terbang yaitu komponen main wing dengan konfigurasi high wing dengan bentuk rectangular, tail wing dengan konfigurasi konvensional, dengan propulsi model tractor, tipe engine TUNDER TIGER 46 PRO (propeller11x6), landing gear dengan konvigurasi nose whell, serta main airfoil menggunakan NACA 2412, dan tail wing airfoil flat type.
Kata Kunci : Conceptual Design, Platform UAV-08v2, NACA.
