Abstract

Struktur pada pesawat terbang berfungsi untuk mentransfer beban-beban yang terjadi pada permukaan pesawat ke bidang lain yang memiliki kekuatan lebih besar sehingga komponen pesawat tidak mengalami kegagalan karena setiap komponen menerima beban yang relatif kecil. Pada perancangan struktur sayap pesawat terbang, hal paling utama yang harus diperhatikan adalah masalah berat dan kekuatan struktur. Struktur yang dibuat harus memiliki kekuatan maksimal dengan berat seringan mungkin serta memenuhi faktor keamanan (safety factor). Penelitian ini melakukan desain optimasi dan analisis kekuatan stuktur sayap pesawat dengan memvariasikan jenis material, thickness dan kondisi batas. Jenis material yang diaplikasikan dalam penelitian ini adalah komposit carbon/epoxy T300/N5208, Alumunium dan Titanium. Material komposit dengan berbagai varisasi susunan arah serat dimana lamina disusun secara simetris dengan arah serat (90°/90°/90°/90°)s, (45°/45°/45°/45°)s, (0°/0°/0°/0°)s, (0°/0°/90°/90°)s dan (0°/45°/-45°/90°)s dan ketebalan per layer nya sebesar 0,000125 m atau 0,125 mm. Thickness dibuat seragam dari wingroot sampai dengan wingtip, kemudian thickness dibuat bervariasi dengan membagi tiga section sayap. Kondisi batas diposisikan di ujung spar dan diposisikan di bagian ujung skin sayap. Desain optimasi dan analisis kekuatan struktur Ribs, Spar dan Skin menggunakan Patran Nastran. Objek penelitian ini pada perancangan geometri sayap mengambil studi kasus pada jenis pesawat UAV CH4 Rainbow milik TNI AU. Dalam penelitian ini diperoleh  stress dan weight pada ketebalan yang seragam dan posisi kondisi batas di spar untuk material komposit sebesar 75,8 MPa, 2,228 x 103 Kg. Material alumunium sebesar 59,2 MPa, 3,871 x 103 dan material titanium sebesar 59,2 MPa, 6,168 x 107 . Desain optimasi dilakukan dalam penelitian ini dengan cara memvariasikan ketebalan dan menambah posisi kondisi batas di ujung skin sayap, diperoleh stress, defleksi dan weight untuk material komposit sebesar 551 MPa , 0,675 m, 277 Kg. Material alumunium memperoleh stress dan weight sebesar 59,2 MPa, 3871 Kg dan material titanium sebesar 59,2 MPa, 6168 Kg.

Abstract

One of the instruments that can be used today for navigation is the IMU (Inertial Measurement Unit) sensor which consists of an accelerometer sensor, gyroscope, and an additional magnetometer. The three sensors are useful for determining the orientation angle. However, the presence of high enough noise in the three-output data can cause the orientation angle to be inaccurate. This study aims to determine the roll, pitch and yaw orientation more accurately using a Kalman filter. This filter is used because it has a lightweight computation and can reduce noise significantly. The results of this study show that the orientation angle calculated using the Kalman filter is close to the actual orientation angle with an accuracy of 99.2% for roll, 99.5% for pitch, and 98.6% for yaw.

Abstract

Aircraft reliability is one aspect that needs to be considered in aircraft operation. The reliability program has been implemented in aircraft maintenance policies, especially for aircraft with high utilization. The reliability program could measure the level of reliability of a component. The nose wheel assy on the ATR 72-500 aircraft is one of the components that has repeated defects, so that a reliability analysis could be performed. The analysis is carried out with a Weibull distribution with data of failure time. From data processing, it was obtained the value of Beta (β) = 3.810138517 which means that the failure characteristic that occurs is early wear out. In addition, the reliability value of R (t) was also obtained for every failure time. The value and graphic shows that the trend is decrease with failure time of component .From the calculation with the Weibull[M1]  distribution, it also showed the Mean Time to Failure (MTBF)  reaches 454.0138741 hours.

Abstract

Magnetoimpedansi (MI) telah diamati untuk sampel multilapisan [Ni80Fe20/Cu]N substrat Cu-Printed Circuit Board. Sistem multilapisan ditumbuhkan melalui proses elektrodeposisi dengan memodifikasi jumlah perulangan multilapisan sebanyak N = 2 sampai 6. Rasio MI dianalisis melalui pengujian impedansi dibawah medan magnet luar pada frekuensi 100 kHz. Jika diaplikasikan sebagai sensor magnet, nilai sensitifitas dapat dianalisa menggunakan persamaan ξ = 2[(∆Z/Z)max]/∆H. Hasil uji dan perhitungan ditemukan keselarasan antara peningkatan rasio magnetoimpedansi dengan sensitifitas sensor berbanding lurus. Rasio MI meningkat ± 1.61 kali lipat dengan penambahan jumlah multilapisan [Ni80Fe20/Cu]N dari N = 2 sampai N = 6 lapis, atau meningkat dari 3.32 % menjadi 5.36 %  sebesar 2,04 %. Peningkatan tersebut kemungkinan disebabkan karena bertambahnya jumlah multilapisan pada sampel meningkatkan permeabilitas bahan magnetik sistem multilapisan itu sendiri. Penambahan jumlah multilapisan telah meningkatkan sensitifitas sensor sebesar ±1,64 kali lipat. Sensitifitas tertinggi didapat pada sampel dengan N=6 sebesar 0,61 %/Oe.
