Abstract

The use of fossil energy and coal has a significant impact on global warming through increased greenhouse gas emissions, particularly carbon dioxide (CO2). To address this issue, green technologies offer sustainable solutions, including the development of electric propulsion systems on unmanned aircraft (UAVs). Electric propulsion uses clean energy sources such as batteries and hydrogen fuel cells, significantly reducing emissions and air pollution. This research explores the importance of applying green technologies in the optimization of electric propulsion on UAVs, and the resulting environmental and economic benefits. Electric propulsion technology not only reduces carbon footprint and air pollution, but also improves energy efficiency and extends the operational life of UAVs. In addition, it allows UAVs to operate more quietly, reduces noise pollution, and can be used in various sensitive environments. The implementation of green technologies in UAV electric propulsion systems faces challenges such as limited battery capacity and recharging infrastructure. However, with collaboration between industry, government and research institutions, as well as regulatory support and incentives, the development of these technologies can be accelerated to achieve more environmentally friendly and sustainable UAV operations. Through the application of electric propulsion technology, UAVs are expected to provide innovative and sustainable solutions in areas such as aerial surveying, security surveillance, and freight forwarding, while making a positive impact on the environment and sustainability of the global ecosystem.

Abstract

Aviation safety is highly dependent on the accuracy of the tools used, including torque wrenches used in aircraft maintenance. This study evaluated the accuracy of the QD2R200 snap-on torque wrench following the ISO 6789-2017 calibration method using the Stahlwille standard. The study was conducted in the Batam Aero Technic calibration laboratory, with torque wrench measurements at their nominal capacities of 20%, 60%, and 100%. Measurements were repeated five times at each nominal point. The calibration results on the two tools in the laboratory showed that the variation in deviation of the tool with serial number 1016901448 reached ±9%, while the tool with serial number 1116802022 had a deviation of less than ±2%. Testing was carried out in clockwise and counterclockwise directions. The t-test showed a significant difference in results between the two tools, namely p = 0.003. These results emphasize the importance of periodic calibration and show that the ISO 6789:2017 method is effective in measuring torque wrench accuracy, which is important in ensuring safety and reliability in the aviation industry.
