Abstract

Inward-turning external compression intake is one of the hybrid intakes that employs both external and internal compression intakes principle. This intake is commonly developed for hypersonic flight due to its efficiency and utilizing fewer shockwaves that generate heat. Since this intake employ less shockwaves, this design can be applied for low supersonic (Mach 1.4 - 2.5) intakes to reduce noise generated from the shockwaves while maintaining the efficiency. Other than developing the design method, a tool is written in MATLAB language to generate the intake shape automatically based on the desired design requirement. To investigate the intake design tool code and the performance of the generated intake shape, some CFD simulation were performed. The intake design tool code can be validated by comparing the shockwave location and the air properties in every intake's stations. The performance parameters that being observed are the intake efficiency, flow distortion level at the engine face, and the noise level generated by the shockwaves. The design tool written in MATLAB is working as intended. Two dimensional axisymmetric CFD simulations validation has been done and the design meets the minimum requirement. As for the 3D inlet geometry, with a little modification on diffuser and equipping vent to release the buildup pressure, the inlet has been successfully met the military standard on inlet performance (MIL-E-5007D). This design method also has feature to fit every possible throat cross sectional shapes and has been proven to work as designed.Keywords— Inward-turning, Supersonic, Engine Intakes, Low- noise, Design Method

Abstract

Technological advancement has forced the international community to deal with the sixth generation of war, which is a conflict involving the most advanced robotics, artificial intelligence (AI), and satellite technology. This shows that warfare has evolved beyond traditional tactics because parties are no longer required to engage in face-to-face combat as they did during the first generation of conflicts. Although the "classic" war still takes place in some regions of the world, it is more sectoral in nature and only in small-scale wars. The researcher needed a description of Indonesian military research and development in dealing with sixth generation warfare: the application of artificial intelligence in military operations, hence the qualitative descriptive research approach was used. The Indonesian National Armed Forces (TNI) must be flexible in light of the dynamics of the world's swift technology advancements, which includes updating defense equipment with artificial intelligence (AI) functionality. Due to increasingly sophisticated danger patterns, the TNI must deploy artificial intelligence, making technological advancements crucial to safeguarding the security of border areas. Keeping the Republic of Indonesia's unitary state intact comes with a "fixed price," one of which is preserving the security of the border region

Abstract

Missile is one of Indonesia 7 self – reliant main weapon system programs. Therefore research on the anti – surface ship missile system concept had been carried out at the Faculty of Defense Technology, Defense University. This research aims to abtain optimal design of anti – ship missile concept from previous research, i.e. 2 stages cruise missile with diameter of 0.36 m, total length of 5.19 m, cruise flight altitude of 17 m, and cruise flight speed of 0.88 Mach. The optimation is done on the missile’s aerodynamics characteristics to maximize its lift to drag ratio, which is one of the factor that determine the missile’s performance. Variables of nose cone shapes, number of wings, and body cross sections were chosen for evaluation of lift to drag ratio. The research found that nose cone shape did not affect the aerodynamic characteristics since the flight speed is subsonic. From the rest of the variables, it is found that the best configuration is missile with 2 wings with root length of 1.18 m, height of 0.79 m, and tip length of 0.71 m, elliptical body cross section, and the missile is to be flown at 6o angle of attack.

Abstract

Numerical simulations of 2-D supersonic and hypersonic laminar Shock-Wave/Boundary-Layer Interactions (SBLIs) were carried out by solving the Navier-Stokes (NS)equations using a compressible flow code over a wide range of Mach numbers and shockstrengths. The results obtained at Mach 2.0 and 7.73 were compared with experimentaldata. In addition, the numerical data were further analyzed using correlation laws derivedby previous researchers based on the free interaction concept, extended here to higherMach numbers. The results indicate that this concept is valid for separated laminar hypersonicflows with SBLIs. For interference heating, the correlation technique based on thewell-established power law relationship between peak heating and peak pressures yieldedencouraging results consistent with other correlations for laminar interference heating athypersonic speeds.

Abstract

Nowadays, several hypersonic vehicle designs have existed and waverider is one of them. Waverider has been introduced for more than 50 years yet only a few have been operated. This is due to several difficulties in design processes dan propulsion system integration. The present research was conducted by designing general wedgederived waverider and integrating it with scramjet inlet. The waverider design process is based on one-dimensional flowfield analysis, while the scramjet inlet integration is based on exergy analysis. Through this investigation, a design variable – Exergy Destruction Rate (EDR) - would be obtained to correlate the waverider design with the integration of scramjet inlet

Abstract

Riset ini bertujuan untuk mendesain intake supersonik untuk aplikasi sistem propulsi ramjet. Desain intake ramjet sangat penting bagi proses pembakaran dalam ruang bakar mesin ramjet. Dalam desain intake konikal ini, kondisi Mach 2 dijadikan sebagai acuan, dengan kompresi eksternal. Penelitian ini juga menguji intake ramjet dalam terowongan angin supersonik. Desain dilakukan dengan menempatkan gelombang kejut pada bibir cowl intake untuk memperoleh pressure recovery yang tinggi dan gaya hambat serendah mungkin. Hasil desain analitik dibandingkan dengan hasil numerik pada berbagai kondisi intake – subkritikal, kritikal, dan superkritikal. Hasil numerik juga divalidasi dengan eksperimen model. Intake yang didesain memberi pressure recovery sebesar 0,93, namun hasil ini cukup berbeda dengan hasil eksperimental. Ini disebabkan karena efisiensi kompresi tidak diikutkan dalam proses desain.

Abstract

This study analyzes the performance of an initial PID controller in the pitch channel of a quadcopter UAV using an empirical flight log exported from UAV Log Viewer. The aim is to evaluate pitch stability and command-following response by comparing desired pitch, current pitch, and North-East position data recorded during a 89.96s valid segment (2649 samples), analyzed through time-history inspection and error metrics. The method applies qualitative-quantitative log analysis with error metrics, time-history inspection, and trajectory interpretation. The results show weak pitch tracking: desired pitch varied from -1.34° to 4.14°, while measured pitch remained narrow at -0.73° to -0.50°; The log yielded MAE was 1.65°, RMSE was 2.04°, IAE = 148.46 degrees, and pitch correlation = 0.03.°. The findings imply that the initial gains are safe for data collection, but inadequate for responsive pitch control and require retuning.

Abstract

In most games, an artificial pathfinding intelligence is required for traversing the fastest discovery. It is essential for many video games, particularly Role Playing Games (RPGs). The algorithm pathfindings implemented in this game are A* and Dijkstra Algorithms. This study aims to test an artificial intelligence system for discovering routes using the A* and Dijkstra algorithms based on RPG Maker MV. The result showed that from the time obtained, in the experiment on eight nodes using the Pathfinding mechanism of A* algorithm has faster result in discovering the nearest route with the time 08:15:23 with format (mm:ss: ms) whereas Dijkstra Algorithm has a 34:47:43 time result. The time record needed represents the distance between the search nodes. It indicates that the multiple weighting in the impassable nodes caused the cost calculation process becomes faster and more efficient.
