Abstract

The fighter aircraft project is one of the defense and security equipment (alpalhankam or alat peralatan pertahanan dan keamanan) priority programs contained in the defense industry roadmap. Indonesia and South Korea undertook a joint development program in developing 4.5 generation fighter aircraft. However, Indonesia experiences several obstacles in the development of fighter aircraft, one of which is the ability of disparity and mastery of fighter technology. One of the critical components used as one of the development programs is simulator technology development. Mastery of simulator technology can improve the ability of Technology Readiness Level (TRL) from technology development fighter aircraft and can cause multiplier effects in other fields. Therefore we need a development strategy that is appropriate for the development of simulator technology. This study aims to analyze and define the benchmark level of performance or from the critical components which will then be used as a reference for the development strategy of the 4.5 generation fighter simulator for joint development projects. The method used in this study is a mixed-method with an approach system engineering uses quality function deployment tools and Critical Technology Element (CTE) technology assessment to identify which CTE then used as a reference strategy for the development of fighter simulator technology. The results of the study show that there are several CTE values along with simulator technology performance scores, among others mission 92.5%, data 83.56%, motion 52.51%, and strategic options that can be used in the technological development of fighter simulator generation 4.5 such as strategic joint development, self-development, and local content/offset.

Abstract

To avoid detection from Radio Detection and Ranging (Radar), one of the efforts is to use Radar absorbing material. One of the Radar wave absorbing materials is Perovskite CoTiO3. This Paper investigated the ability of CoTi(1-x)Mn(x)O3 to absorb the Radar wave. CoTi(1-x)Mn(x)O3 with variations x = 0, 0.01, 0.02, and 0.03 have been successfully synthesized using the mechanical milling method. The XRD pattern shows that the sample formed was single phase CoTiO3. Surface morphology resulting from measurements with SEM shows homogeneous particles and an average size of 200 nm. The results of measurements with VNA at X-band frequency (8.20 GHz - 12.4 GHz) show that the absorption ability of electromagnetic waves from CoTiO3 increases with the increase in doping from Mn4+. Maximum results obtained at the composition x=0.03 (CoTi0.97Mn0.03O3) with a reflection loss (RL) value is -14.56 dB (%Abs is 81.3%) at a frequency of 9.96 GHz. This result proves that CoTi(1-x)Mn(x)O3 can be used as a Radar absorbing material at X-band frequency.

Abstract

The Anti-Tank Guided-Missile (ATGM) system has a very important role in the modern battlefield. This system proved its effectiveness in many modern conflicts such as the Syrian Civil War and Nagorno-Karabakh War. The ATGM system has a very simple electronic and mechanism but it has a very high level of accuracy and precision. One of the control methods used in ATGM is SACLOS method. This method tracks missile position by detecting an infrared lamp that is placed on the missile tail. The tracking system sends control signals to the missile as a result of the correction of the missile position when flying. The infrared tracking system in this research was made using a modified OV5647 camera with the addition of a 940 nm narrow bandpass filter. There are 3 cameras with 1x, 8x, and 16x magnifications which are accessed using 3 Raspberry Pi boards. X and y coordinate data of the infrared lamp is sent to the airframe using wireless telemetry. Atmega328 microcontroller process x and y coordinate data into input proportional control. The result of this research is the prototype of an anti-tank missile control system with an infrared tracking instrument capable track a series of 88 infrared LEDs as far as 997.16 meters with a tracking speed of 90.11 FPS. The threshold parameters of image processing using luminance of YUV color space has a range of 240-255. The control parameter Kp=7 is used in wind tunnel testing with airspeed 20 m/s capable of directing airframe motion to the telescope's crosshairs.
