Rancang Bangun Alat Fuel Nozzle Tester Menggunakan Media Bantu Pneumatic Sebagai Media Pembelajaran Gas Turbine

Abstrak

Fuel nozzle maintenance is necessary if a blockage occurs, usually caused by carbon buildup at the tip. When more fuel flows through one nozzle than another nozzle, it will cause the combustion gas coming out of that area to be hotter than average. This will reduce the life of the hot section of the gas turbine engine. One of the maintenance methods used to determine the condition of the fuel nozzle is by simulating a tool that can be seen with the naked eye to determine the condition of the fuel nozzle. Based on observations, the current availability of tools, namely the PT6A fuel nozzle tester using jacking, is not yet complex and not yet optimal in terms of performance and operation because the tool can only test the fuel nozzle one by one, so appropriate innovation is needed to overcome the obstacles that occur. In this research, a fuel nozzle tester was designed using pneumatic auxiliary media. The method used is the research and development method by producing an item and then testing its effectiveness. The design begins with determining the design, tool components, working methods and then testing techniques. From the test, data analysis was carried out to determine the effectiveness of the tool. It is known that the design of a fuel nozzle tester using pneumatics can increase effectiveness in testing fuel nozzles. When testing the PT6A engine fuel nozzle using a pneumatic fuel nozzle tester, there was a fuel nozzle in the non-acceptable category on fuel nozzle no.1 due to a blockage so cleaning had to be carried out. Then, from the data analysis of the questionnaire results, it shows that this tool is very effective for use in cadet learning media with the results of the tool design questionnaire: 98.3%, tool function: 97.1%, tool usefulness: 97.1% strongly agree
