PERBANDINGAN METODE MANUFAKTUR PROPELLER CLARK Y: 3D PRINTING DAN SILICONE MOLDING
Abstrak
Saat ini, industri penerbangan berkembang sangat pesat, tidak hanya pada pesawat berawak, tetapi juga dalam pengembangan pesawat tanpa awak atau Unmanned Aerial Vehicle (UAV). Salah satu komponen krusial pada UAV adalah propeller. Metode yang umum digunakan dalam proses manufaktur propeller antara lain adalah metode forming, hand lay-up, dan vacuum bagging. Metode lain yang berpotensi menjadi alternatif adalah pencetakan menggunakan silikon (silicone molding) dan pencetakan tiga dimensi (3D printing). Penelitian ini bertujuan untuk mengetahui jenis metode manufaktur yang paling sesuai untuk pembuatan propeller dengan tipe airfoil Clark Y. Penelitian dilakukan menggunakan metode simulasi, analisis geometri, dan analisis visual. Metode manufaktur silicone molding dapat digunakan sebagai alternatif selain injection molding karena perbedaan ukuran antara desain CAD dan hasil akhir dari metode ini tidak terlalu signifikan, dengan nilai penyusutan terbesar sebesar -8,77%. Sementara itu, metode 3D printing lebih sesuai digunakan ketika ukuran airfoil lebih tebal.
