Abstract

This program is aimed for teachers from SMK N 12 Bandung. Through this PKM (Community Service Program), it is expected that the training participants will gain insights and enhanced knowledge regarding aircraft maintenance, particularly the maintenance of gas turbine engines. The training was conducted at the Propulsion Laboratory, Aeronautical Engineering Hangar, Department of Mechanical Engineering, from October 12 to 16, 2021. The aircraft engine maintenance training began with a pre-test to assess participants' initial knowledge of aircraft engine maintenance. At the end of the training, a post-test was conducted to measure the improvement in their understanding and knowledge. The outcome of this PKM activity is a certificate of participation in the aircraft maintenance training, specifically focused on gas turbine engines.

Abstract

This study discusses the effect of variations in the parameters of the welding process on the tensile strength and Vickers hardness tests. In general, it is widely known that in the fabrication process, welding is a very important process that is used to join two or more materials. The welding process is carried out with variations in the strength of the welding current, namely 75, 85, and 95 A. The experimental method used in this research is AISI 1045 steel material with a thickness of 6.0 mm. The results of the tensile strength test have the highest value at a current strength of 75 A which is equal to 756.642 MPa. The lowest tensile strength test results were obtained with a tensile strength of 687.608 MPa at a current strength of 95 A. specimens with variations in current strength of 95 A have the highest value in the Vickers hardness test, with a hardness value of 281.25 HV. From the research conducted it is known that as the welding current increases there is a decrease in the value of the tensile strength. The hardness value in the heat affected zone (HAZ) area of all test specimens has the highest value, while the hardness value of weld metal (WM) and base metal (BM) has almost the same hardness value.

Abstract

Galvanic corrosion is a type of corrosion that often occurs in aircraft structures. This type of corrosion occurs because two different types of materials contact each other through an electrolyte media. As a result of this galvanic corrosion, several components in the aircraft structure can be damaged. One example of this damage is the corrosion of the bolts on the aircraft skin. So that makes it difficult to remove from the skin. One way to loosen the bolts due to galvanic corrosion is by heating. By using induction heater to the component, the rusty bolt can be loosened. The heat generated causes the bolt to stretch and break the corrosion and so that the bolt or nut can be opened easily. In this research, by using an Arduino Mega 2560 model to remove bolts and nuts with an open loop and closed loop system was conducted. Arduino Model as a microcontroller which is needed to run a program. The specimens of the bolts are using steel bolts grade 8.8 with key sizes 13, 17, and 19. The temperature to produce induction heater is set to a temperature of 150 °C. The results show that to reach 150 oC each of the key size its produce a different duration of time. Key size 13 took 190 seconds with 35.64 watts of power, key size 17 took 279 seconds with 36.96 watts power and the 19 key took 296 seconds with 41.43 watts power.

Abstract

UAV (Unmanned Aerial Vehicle) atau RPV (Remote Controlled Vehicle) merupakan wahana terbang yang dikendalikan dari jarak jauh oleh seorang pilot dan dapat terbang secara manual atau autonomous. Teknologi ini menjadi solusi di berbagai sektor, termasuk pertanian, yang membutuhkan efisiensi dalam proses penyemprotan pupuk cair. Pada penelitian ini akan dilakukan kaji terhadap sistem kendali pada RPV fixed wing untuk misi terbang menyiram pupuk cair ke lahan pertanian. Diharapkan dengan RPV ini dapat meningkatkan efisiensi dan efektifitas dari proses pemupukan pada lahan pertanian dengan memanfaatkan teknologi pesawat tanpa awak. Sistem instrumentasi yang akan dikaji mencakup perangkat navigasi serta mekanisme penyiraman pupuk cair yang terintegrasi secara otomatis. Kajian ini meliputi analisis kebutuhan hardware dan software, desain sistem kontrol, serta uji terbang. Hasil dari penelitian ini diharapkan dapat menjadi referensi untuk pengembangan lebih lanjut mengenai teknologi RPV dalam bidang pertanian.

Abstract

Perkembangan teknologi wahana terbang di dunia terus mengalami kemajuan pesat, ditandai dengan semakin luasnya penerapan dalam berbagai bidang. Wahana terbang kini tidak hanya dimanfaatkan untuk transportasi dan militer, tetapi juga untuk fotografi udara, pengawasan, patroli, serta penelitian. Salah satu teknologi yang berkembang pesat adalah RPV (Remote Piloted Vehicle), yaitu pesawat tanpa awak yang dikendalikan dari jarak jauh dan dapat beroperasi secara manual maupun otomatis. Salah satu potensi pemanfaatan RPV yang belum banyak dikembangkan adalah di sektor pertanian, khususnya dalam proses penyiraman pupuk cair. Penelitian bertujuan untuk melakukan rancang bangun dan manufaktur RPV dengan sistem fixed landing gear untuk kebutuhan penyiraman pupuk cair. Pemilihan material ringan namun kuat menjadi salah satu aspek penting, agar pesawat memiliki daya angkut yang cukup dan memiliki performa terbang yang baik.

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.
