Abstract

Untuk mengetahui kekuatan struktur suatu pesawat terbang, dilakukan perhitungan dan analisis kekuatan struktur. Struktur sayap pesawat terbang yang disusun dari material komposit, penghitungan dan analisis kekuatan struktur salah satunya dilakukan dengan menghitung failure index untuk masing-masing layer/susunan dari material komposit tersebut. Pada penelitian ini, struktur sayap Pesawat terbang tanpa awak (PTTA) Ai-X1 yang terbuat dari material komposit dianalisis kekuatan strukturnya dengan menghitung failure index dari masing-masing layer/susunan material komposit tersebut. Perhitungan failure index dilakukan dengan menggunakan kriteria kegagalan Tsai-Hill. Hasil dari penelitian ini yaitu nilai failure index pada masing-masing layer/susunan material komposit struktur sayap pesawat Ai-X1. Berdasarkan kriteria Tsai-Hill masing-masing layer/susunan tersebut menunjukkan tidak adanya keretakan pada lamina.

Abstract

In this research, the process of identifying aircraft parameters is carried out for the lateral-directional dimension by notice the variations of the given control surface deflection input. The inputs are pulse, doublet and 3-2-1-1. Among the input forms, it is not known which form is most suitable for the lateral-directional dimension. Simulation is done by varying the input deflection control surface and simulation time. The input given is deflection of the aileron and rudder control surfaces. This research uses the equation error method with the ordinary least square estimation technique. The purpose of this research to identify the most suitable input for the identification of parameters in the lateral-directional dimension and to observe the effect of simulation time. The aircraft used is the Lockheed C-5 Galaxy. The simulation results show that the combination of the 3-2-1-1 input form in the aileron deflection surface and the input pulse shape on the rudder has an error value of about 0.09. This value is smaller among all cases seen from the error matrix A. Based on that, the combination of the two inputs is the most suitable for the lateral-directional dimension than the other inputs that have been given.
