Abstract

Required Navigation Performance (RNP) is known as a performance parameter for a navigation system, where its function is to keep an aircraft within a certain radius of containment. During the flight, an aircraft transmits its real-time location-based on Global Navigation Satellite Systems (GNSS) technology via Automatic Dependence Surveillance Broadcast (ADS-B) protocol. However, there are questions about the flight position accuracy. This research aims to analyze the accuracy of ADS-B flight data about RNP requirements. The flight data used is gathered from the FlightRadar24 website and filtered for each flight phase. The selected route used is Makassar (UPG) – Jakarta (CGK) because the route has the highest number of flights per week. The Dot Product method is proposed to calculate the distance between the flight trajectory to the line of flight procedure towards the destination airport. The analysis is conducted based on the compliance of the flight data to the RNP threshold. It is concluded that the majority of evaluated flights in the selected route fly within the RNP boundary. However, some non-complying flights become within the RNP boundary when they are evaluated with other possible published procedures

Abstract

The need for a transportation system to transport goods is increasing, especially for regions in Indonesia that are included in the leading, remote, and disadvantaged (3T) categories. This paper will discuss the conceptual design of an unmanned cargo aircraft with a piston-propeller engine which can later be operated in the 3T area. The design will begin with a discussion of DRO, followed by a concept of the aircraft configuration. After the configuration is formed, the aerodynamic characteristics will be calculated, the weight will be predicted, and flight performance calculations and aircraft stability will be calculated

Abstract

Nowadays, human sensory and motor skills enhancement is very important to be alert from the effect of the Society 5.0 era. We propose the novel approach to enhance human sensory and motor skills using collaboration of senses focus and body parts gesture in no-touch3D interactive aircraft game. A player interacts with a virtual display using gestures of his body, arm, hand, or collaboration of them as a controller to engage in a 3D game. This game is based on an aircraft education theme. By sweeping the hand to the left or right, a player can select one of many different aircraft models according to its specification and performance are shown on the screen based on the estimation of his current skill. The mission is to control aircraft avoiding the random balls attack to prevent a collision. Hand and arm are positioned above a leap motion sensor and in front of a camera. The body, arm, and hand gesture directions are to forward or backward from the screen to the right or left, and also to up or down freely. This system is developed by using Unity 3D, OpenCV, and Python. Many skills are possible to be improved, e.g., motivation, discipline, safety awareness, endurance management, strategy, precision, intelligence, creativity, reliability, toughness, and vision. This project has been tested in the Air Force Museum of Dirgantara Mandala involving more than 1000 visitors as testing participants, and they all feel satisfied. The score is calculated by time in second. The results show endurance time is 32% (<60 s), 31% (<120 s), 25% (<160 s), and 12 % (180 s) of the total300 seconds of the game

Abstract

This article aims to prove that Machine Learning (ML) methods are effective for Predictive Maintenance (PdM) and to obtain other developing methods that suitable applied on PdM, especially for aircraft engine, and potential method that can apply on future research, and also compared between articles in International and Indonesia institution. Maintenance factors are important to prognostic the states of a machine. PdM is one of the factor strategies based on realtime data to diagnosis a failure of the machine through forecasting remaining useful life (RUL), especially on aircraft machine where the safety is priority due to enormous cost and human life. ML is the technique that accurately prediction through the data. Applied ML on PdM is the huge contribution for saving cost and human life guarantee of safety. This work provides the literature survey for recent research which trends and challenges on PdM of aircraft engine using ML that compared the research from international and Indonesia from 2016 to 2021. Result of this work shows that ML method, Long Short-Term Memory (LSTM) and Gated Recurrent Unit (GRU) are the best method to calculate PdM with more than 99% on rate accuracy, and low level of Indonesia institution research which focused on PdM on aircraft engine using ML

Abstract

To reduce losses due to fire, it is necessary to extinguish and rescue immediately. However, in the dense area fire trucks were unable to reach the fire site due to narrow road access. In this case, drones that can fly by themselves to the point of fire then release fire-fighting bombs automatically can help fire disaster management. This means it needs a system where it can identify whether there is a fire. This study explores the idea of identifying fire using computer vision approach by making 8 identification models with each dataset of day, night, day, and night, thermal, day filter, night filter, day and night filter, and thermal filter, which had been tested by a set of data that corresponded to each dataset. YOLOv4 algorithm and Google Colaboratory were used, where each model took 8-10 hours to be trained. Results show that the day and night model was the most robust by having the highest average F1-score, 0.37. And will be performing the best on thermal data test with the value of F1-score is 0.6. This can be a representation for exploring new ideas on further study of how to obtain the most suitable dataset and data test.

Abstract

LSU-05NG is a drone manufactured and developed by LAPAN. The horizontal tail of the aircraft is used to maintain longitudinal stability, however, there has been no study on a tail modification that could improve the performance. The study of tail modification will examine the impact of modifying the airfoil to NACA 2412 and NACA 63-215. The base model of LSU-05NG uses NACA 0012 as the airfoil profile which is used in the horizontal tail. The performance is measured from the value of the lift coefficient, drag coefficient, and longitudinal stability. The results are obtained using ANSYS CFX Software. Based on the study, the modification of the horizontal tail has no impact on the lift and drag coefficient, however, impacts greatly on the pitching coefficient which determines the longitudinal stability. The airfoil profile that produces the highest longitudinal stability is NACA 63-215, followed by NACA 2412, and the last is the basic model using NACA 0012

Abstract

Demands for delivering a more sustainable and eco-friendly aircraft increase for the near future. However, the technology of current electric power for the aircraft (e.g., electric motors and batteries) is still lacking compared to matured power technology using fossil-fuel. A preliminary design of electric aircraft becomes initial important steps to obtain matured fully electric aircraft. This design step requires various analytical and software-based analyses to fullfill the design requirements and objectives. The design requirement of designing electric aircraft is aircraft with maximum take of weight of  5000 equipped with 6-seater. From the design results show that the designed aircraft fulfills all the requirements and most of the objectives. The design itself still need furtherdevelopment through optimization, re-evaluation, future studies, and upcoming technologies.Keywords: Aircraft Design; Electric Aircraft; Sustainability

Abstract

The present work investigates the influence of gas at high temperature on the design and analysis of two-dimensional plug nozzle. The thermochemical and combustion studies of liquid launchers propellants make it possible to choose the gases to be studied. For example, four cases of bi-propellants engines have been studied. The combinations studied are: H2/O2, RP1/O2, CH4/O2 et MMH/N2O4. The selected gas are: CO2, H2O H2, N2 and CO. Once the profile is generated, an analysis of the thermodynamic-parameters evolution (such as: length, Mach number, mass, thrust coefficient) and aerodynamic performances is conducted. Some results were presented and compared with previous research using air. The comparison shows that the presence of H2O and CO2 gases considerably increases the performance of nozzles. The percentage of gases in the combustion has an influence on these increases. In order to minimize the weight of this nozzle, the truncation of Plug nozzle in order to increase their performances is studied in this research.

Abstract

The island of Kalimantan, especially the East Kalimantan area, has been included in the discourse on the development of the State Capital of the Republic of Indonesia. It is necessary to carry out further scientific studies from various aspects, one of which is rainfall. The Meteorology and Geophysics Agency (BMKG) and NASA's The Tropical Rainfall Measuring Mission (TRMM) are agencies for measuring rainfall in Indonesia. The BMKG ground rainfall data recording still leaves a void given the limitations of recording at rain observation stations, while the TRMM satellite rainfall data can provide complete data. The purpose of the study was to analyze the equations and correlations of ground rainfall data BMKG and TRMM satellite rainfall data and analyze the feasibility level of TRMM satellite rainfall data to be able to represent BMKG ground rainfall data that is missing or out of reach of rainfall observation stations. Rainfall data was used for 20 years (1998-2019) at rain stations on the island of Borneo. Data were analyzed in the form of daily, 7 daily, monthly and yearly. The results of the correlation analysis showed that the greater the cumulative number, the greater the similarity of the BMKG and TRMM patterns, with the highest correlation value in the annual cumulative (0.661-0.909). TRMM rainfall data is considered capable and feasible as an alternative in filling in missing BMKG rainfall data, especially as a substitute for certain area data that is difficult to measure.
