Abstract

The characteristic model of MUS-01 wing structure testing has been performed. Planned, this model will be used as an unmanned wing of the LSU-03NG. The test model is made of composite type e-glass. At the time of testing the structure test model is loaded according to MTOW weight. This research method also involves the unmanned aircraft mission, especially on the model test structure, model dimension, and direct experiment in the form of loading on the test model. The result of characterization of the test model during test, showed that the indicated test model has the characteristics as a test model that is unable to accept the unmanned operational load of LSU-03NG series aircraft. So it can not be used as a consideration for the structure of the unmanned aircraft.

Abstract

Landing Gear Drop Test (LGDT) which aims to determine the characteristic of contact/impact force that occurs in the time of the touchdown landing has been conducted. Experimental tests using the apparatus requires a substantial time and cost. Virtual Landing Gear Drop Test (vLGDT) using MSC ADAMS software is one of the solutions for initial stage to testing landing gear. Stiffness values and damping coefficient obtained from vLGDT are 5.0e5 N/m and 1600 N.sec/m. Contact/impact force that occurs on vLGDT is 75996 N, while from experimental is 73612 N. The difference between vLGDT and experimental result is 3.14%.Abstrak:Pengujian landing gear yang bertujuan untuk mengetahui karakteristik gaya kontak/impak yang terjadi saat touchdown landing telah dilakukan. Pengujian eksperimental menggunakan apparatus membutuhkan waktu yang lama dan biaya yang besar. Vitual Landing Gear Drop Test (vLGDT) menggunakan perangkat lunak MSC ADAMS merupakan salah satu alternatif untuk pengujian tahap awal landing gear. Dari simulasi menggunakan vLGDT diperoleh nilai k = 5.0e5 N/m dan cmax = 1600 N.detik/m. Gaya kontak/impak yang terjadi pada simulasi menggunakan vLGDT sebesar 75996 N, sedangkan dari eksperimental sebesar 73612 N. Hasil vLGDT lebih besar 3.14% dibandingkan eksperimental.
