ANALISIS KINERJA SAYAP ORNITHOPTER SEPERTI-BURUNG SEDERHANA
Abstrak
Ornithopter atau sayap mengepak adalah robot yang menyerupai mekanisme sayap burung, serangga, atau kelelawar. Penerapan UAV jenis ini mulai dari fotografi hingga militer. Pokok bahasan penelitian ini adalah perancangan dan konstruksi sistem mekanik sayap ornithopter dengan sistem kepakan sayap double-joint. Kebaruan yang disampaikan dalam penelitian ini adalah bahan yang digunakan untuk membuat sayap ornithopter yaitu batang karbon untuk kerangka dan plastik untuk sayap. Tujuannya adalah untuk mengetahui kinerja aerodinamis sayap dan seluruh ornithopter. Hasil penelitian menunjukkan bahwa untuk sayap tunggal, nilai CL/CD tergolong tinggi. Namun desain ornithopter harus diperbaiki agar gaya dorongnya lebih tinggi dari gaya drag. Selain itu, kecepatan mulai meningkat secara stabil pada throttle 33,3%. Selanjutnya pada ornithopter ditemukan gaya angkat yang lebih besar dibandingkan gaya turun, sehingga secara teori robot dapat terbang. Lift terbesar terjadi pada nilai frekuensi 0,88 dan 0,97.
