Abstract

Abstract - Airplane is a very important mode of transportation, one of which is ATR aircraft. In this study, the type of aircraft used was the ATR 72-600 aircraft. One of the safety factors that need to be considered on aircraft is the landing gear system. The landing gear system regulates the wheel system on the aircraft for landing and also taking off. Given the importance of ensuring that the plane's wheels are securely locked or not, an up lock box system is needed on the landing gear. In the Up Lock Box system, it is not directly visible from the outside so that the working mechanism is not widely known. This study aims to determine the workings of the up lock box nose teaching aid system on the landing gear and to make a trial up lock box nose teaching aid on the landing gear. The research method begins with a literature study, then looks for design references, namely from the ATA 32 training manual. After that, make a design using the image of the up lock box from the ATR 72 aircraft, assemble the demonstran tool, calibrate and test the demonstran tool. The conclusions in this study are, how the up lock box teaching aids work in accordance with the up lock box working concept in the training manual, the results of the design and manufacture of props accompanied by modifications, as well as the test results on up lock box props in accordance with the up lock work concept box. The size of the props that have been made has a length of 37.8 cm and a width of 16.2 cm.

Abstract

Delivery of goods (cargo) between islands or between countries is faster by air transportation. Air cargo can use passenger aircraft (bulk cargo), Air freighters, Combined air freighters, Converted freighters for the same type of aircraft, such as ATR 72-600. This study discusses fuel consumption, comparison of payload capacity, and comparison of fuel consumption per payload of ATR 72-600 aircraft for the Makassar – Kendari route. namely the ATR 72-600, ATR 72-600 Freighter and ATR 72-600 Converted aircraft. The method used is a quantitative method. The results of the calculation using the flight crew operation manual for ATR 72-600 passenger fuel carried 1.143,4 kg and fuel consumption of 609.4 kg, ATR 72-600 Freighter and Converted aircraft carried 1.210,3 kg of fuel and 613,3 fuel consumption, 4 kg. Fuel costs per kg of cargo, ATR 72-600 Passenger aircraft are more expensive, namely Rp. 1,279 per kg, freighter Rp. 1,136 per kg, converted bulk cargo Rp. 1,175 per kg, Converted Large cargo door Rp. 1,202 per kg. The largest Cargo capacity is 9,000 kg on ATR 72-600 Freighter aircraft and the smallest is 2,150 on ATR 72-600 Passenger aircraft. If cargo delivery does not exceed 2,150 kg, it is more profitable to use ATR 72-600 passenger aircraft, but if the weight or volume sent much larger should use the ATR 72-600 Freighter.

Abstract

This research conducted a comparative analysis of propeller dimensions for the conceptual design of a piston aircraft. The method used is statistical linear regression by comparing some variables related to propellers from 27 piston aircraft data. Based on comparison results obtained 6 strong relationships, namely aircraft speed and engine power, aircraft weight and engine power, aircraft weight and propeller weight, aircraft weight and the number of propellers blades, engine power and propeller weight, and propeller weight and the number of propellers blades so that it can be used for conceptual design reference. The propeller diameter and engine speed variables do not have a strong relationship in regression but form a cluster so that it can be used as a conceptual design reference. The conceptual design simulation with an aircraft weight of 3500 lb produces a propeller with a diameter of 80 inches, the engine power of 325.51 hp, propeller weight of 86.13 pounds, engine speed of 2500 rpm, and 3 blade propellers with a thrust of 1340.05 lbf.

Abstract

With the area and geography of Indonesia consisting of small islands, causing the difficulty of exploration efforts of Natural Resources (SDA) in these small islands. Companies that carry out these exploration activities must build supporting facilities to facilitate the exploration process in the area. The airport is one of the supporting facilities built by the company for exploration activities. The airport built by the company to support this air transportation, must be built according to the land and needs of the company, one of which is the runway. With limited runways, many companies use ATR 72-500 aircraft as charter aircraft to support exploration activities in areas far from commercial airports. Therefore, an analysis of the performance of the ATR 72-500 aircraft as a charter aircraft with the Route Halim Perdanakusuma Airport (HLP) -Matak (MWK) and Halim Perdanakusuma Airport - Badak Bontang (BXT) to determine operational costs. The performance of the ATR72-500 aircraft is seen from the take-off performance needed, range, fuel consumption, and payload. On the route HLP-MWK with 68 passengers traveled with a distance of 577 NM requires fuel as much as 2,456 kg with TOW 22,342 kg, while for take-off requires runway length of 1056 m, operating costs of Rp. 235.535.469, 92 and the cost per passenger is Rp. 3.463.756,91. For the route HLP-BXT with 68 passengers traveled with a distance of 742 NM requires fuel as much as 2.584, 862 kg with TOW 22.471 kg, while for take-off requires runway length of 1068 m, operational costs of Rp. 247.891.620, 16 and the cost per passenger is Rp. 3.645.465.

Abstract

Corrosion is the destruction of materials caused by the environment, where metals separate from their metal atoms and form compounds from water or gas, resulting in oxidation until the metal atoms disappear. Corrosion can also be referred to as material that is damaged by the environment and is mostly caused by natural impacts that increase as the age of the aircraft increases. Failure to maintain the strength of the main structure is caused by excessive stress that occurs in the corrosion area resulting in cracks in the structure. Due to the frequent occurrence of corrosion in the aircraft, observations, data analysis and further literature studies were carried out. This study aims to determine the relationship between aircraft aging and the amount of corrosion found during periodic "c-check" servicing of Airbus A320-200 aircraft at the study site. The research method that used in the discussion of this thesis is to use pearson product moment correlation analysis on age data and the amount of corrosion that occurs on each aircraft. The conclusion of the results is analysis using the Pearson product moment method on 30 sample aircraft, the correlation 0.922 is categorized as having a very strong relationship. Each aircraft section does not have a strong correlation between corrosion and age, but as a whole has a strong correlation with age. From the results of the analysis using the linear regression equation, it can be identified and estimated the amount of corrosion that occurs at a certain age on the Airbus A320-200 aircraft. The results of the linear regression equation show that the aircraft is 23 years old, the amount of corrosion that will arise is estimated at 39 points, it can be concluded that aircraft with XU-029 registration are known to have a total corrosion rate of 42 points with poor corrosion conditions, then when compared to aircraft with registration XU-030 which is 23 years old is also known to have a corrosion rate of 30, so it can be concluded that the corrosion conditions on this aircraft are better than expected.

Abstract

Setiap komponen elektronik yang terpasang pada pesawat menghasilkan panas yang harus dikontrol agar setiap komponen elektronik dapat berkerja dengan baik dan menghindari terjadinya panas yang berlebih. Panas yang dihasilkan oleh komponen elektronik pada pesawat Airbus 320 didinginkan oleh sistem Avionic Equipment Ventilation (AEV). Salah satu komponen AEV ialah Skin Air Outlet Valve yang merupakan katup pembuangan udara panas, katup ini harus tertutup ketika terbang dan terbuka ketika pesawat di darat (suhu skin lebih dari 12 derajat celcius). Jika terjadinya kegagalan pada katup utama dan terbuka ketika pesawat terbang, maka sistem pressurization akan terganggu dan menyebabkan operational interruption seperti Rejected Take-Off (RTO), In-Flight Turn Back (IFTB), Return To Apron (RTA) dan bahkan Aircraft On Ground (AOG).  Perlunya analisis keandalan serta menentukan langkah-langkah yang tepat agar operational interruption dapat diminimalisir. Dengan menggunakan metode perhitungan Alert Level, MTBUR, serta metode Root Cause Analysis (RCA), didapatkan hasil grafik CURR yang melebihi batas AL pada bulan Mei 2022 dan nilai tertinggi MTBUR adalah 9935,63 FH dan nilai terendahnya adalah 5672,26 FH. Terlihat MTBUR dari SAOV maskapai BBB berada dibawah dari MTBUR worldwide dan guarantine MTBUR. Hasil dari perbandingan ini memperlihatkan keandalan dari komponen SAOV yang buruk. Faktor utama penyebab gagalnya Skin Air Outlet Valve (SAOV) menutup saat penerbangan berlangsung diketahui adanya beberapa kesalahan yang disebabkan oleh faktor kelalaian dan prosedur yang kurang detail. Adapun tindakan korektif yang dilakukan seperti penambahan prosedur pemeriksaan dan catatan pada dokumen MEL, merekomendasikan overhaul setiap 7000 FH dan rekomendasi untuk setiap engineer yang melakukan perawatan supaya mengikuti langkah-langkah pada AMM.

Abstract

Information on weather conditions is needed to support flight safety, especially in the process take-off. One of the required weather information is wind data, wind direction and wind speed. One of the wind components is the tailwind(wind from behind). In the small airports it can only be visited by aircraft such as ATR72 and its kind, due to the limited availability of runways and currently many of these airports are still using landing and take-off in the direction of thewind. This can result in a lack of lift during take-off during the tailwind conditions. To prevent this from happening, there is a reduction in the capacity of the aircraft. The purpose of this study was to analyze the performance of the ATR72 aircraft during take-off with tailwind conditions. By calculating the takeoff under normal conditions on the ATR72 aircraft then varying the tailwind speed. The results obtained are the value of the ground roll distance  (????????) and the reduction in aircraft weight (????) at the time of tailwind. a speed tailwind of 0 or normal, obtained a distance of ground roll 849 m, take-off weight of 20948 kg, reduction in aircraft weight of 0. Speed tailwind of 5 kts, distance of ground roll 773 m, take-off weight of 20333 kg, reduction in aircraft weight of 615 kg, while speed of tailwind 10 kts obtained distance of ground roll 697 m, take-off weight of 19308 kg, reduction in aircraft weight of 1640 kg, and speedtailwind of 15 kts, distance of ground roll 621 m, take-off weight of 18225 kg, was obtained. reduction in aircraft weight by 2723 kg.

Abstract

An increase in flight frequency can have a negative impact on the surrounding environment, one of which is high noise levels. Noise can come from full activity, runway stay, movement towards the runway, or aircraft engine testing. Airplane noise during take-off is one of the environmental problems that need attention at airports. The height of the aircraft's trajectory during take-off can affect the noise level generated by the aircraft, but not much research has been conducted to measure the impact of variations in the height of the disturbance on the noise level of aircraft at Halim Perdanakusuma Airport. This study aims to measure the noise level of aircraft during take-off with variations in track height at Halim Perdanakusuma Airport. The method used in this study is to observe 4 aircraft taking off at Halim Perdanakusuma Airport with a research time of 3 days, and the measuring instrument used is a sound level meter. Sound level meters measure noise in dBA units between 30 and 130 dB at a frequency of 20 to 20.000 Hz. Based on the calculation and measurement results obtained, it is known that the maximum height when the measurement is on the second day is at point A of 277 meters, while at point B is 299 meters. While the highestnoise measurement at point A is 93,1 dB while at point B it is 91,5 dB. The measured noise value based on calculations is estimated at 66,2 dB and is still below the Airbus A320 aircraft noise certification for flyover takeoff of 73,7 dB.
