Abstract

Landing gear system pada beberapa pesawat masih menggunakan sistem elektromekanik dengan sejumlah kumpulan relay tanpa kendali terpusat. Penelitian ini akan mencoba menggantikan relay elektromekanik tersebut dengan menggunakan smart relay agar menjadi rangkaian yang lebih sederhana. Selanjutnya sistem dapat dikendalikan dan diprogram secara terpusat. Sistem yang diimplementasikan berupa simulator kontrol dari landing gear system menggunakan smart relay dengan bahasa pemrograman Function Block Diagram (FBD). Berdasarkan perancangan, instruksi FBD untuk implementasi sistem menggunakan instruksi OR, Set-Reset dan Timer. Dengan instrusksi tersebut, simulator ini telah berhasil menggerakkan piston Double Acting Cylinder (DAC) sehingga roda pesawat dapat bergerak naik dan turun, serta dapat memberikan sejumlah informasi kepada pilot melalui indikator berupa buzzer dan sejumlah LED. Pengujian dilakukan untuk 6 kondisi, yaitu pesawat di darat, lepas landas, di udara, pesawat terbang rendah, mendarat dan kondisi pergerakan DAC yang bermasalah. Keseluruhan sistem telah bekerja sesuai dengan spesifikasi sistem.
