Abstract

Special tools for retaining bolt key-washer removal are not available, it cause retaining bolt key-washer cannot be removed at PT6A-20A engine practical, so that need to design these special tools. First step to design retaining bolt key-washer detachment tool as gas generator turbine disk aiding detacher tool for motor turbine PT6A-20A is to define weight, dimension, and force in which the tool is used. Then followed by the calculation and measuring process so that the shape, dimension and material for this tool can be determined. Next the writer start to design based on the available calculation and measurements by using theories related to this particular design. Then followed by the manufacturing of the tool based on the design being made.The tool is manufactured with 24,6 mm of detachment tool diameter and have 7,2 mm of high and 2,2 mm of thick. Protector tool have 38 mm outside diameter and 26 inner diameter. From the result of testing process,the retaining bolt keywasher dettachment tool has successfully removed the retaining bolt keywasher with the moment 78.056,60 N-mm and the protector toll has succesfully to protect hole of gas generator turbine disk shaft with moment 23.416,05 N-mm. And is set to use on cadet’s practice to fulfill motor turbine syllabus due to the unavailability of protective tool on the axle of gas generator turbine disk and retaining bolt key-washer detachment tool on gas generator turbine disk on motor turbine PT6A-20A in Hangar 01 Aircraft Engineering

Abstract

B.Indonesia Penggunaan turbin sangat luas, sesuai dengan fungsinya turbin didisain dalam bentuk khusus untuk dapat melakukan fungsinya tersebut, salah satunya turbin dapat digunakan sebagai turbin ekspansi pada air cycle machine yang digunakan sebagai sistem pendingin udara di kabin pesawat terbang. Perancangan turbin radial satu tingkat sebagai turbin ekspansi yang mudah dan murah biaya produksinya serta memiliki efisiensi yang tinggi. Perancangan ini diawali dengan menghitung parameter disain awal dan dilanjutkan dengan tahapan perancangan mendisain impeler turbin, nosel inlet turbin dan scroll turbin. Parameter disain turbin yang diperoleh dari perhitungan mencakup parameter non dimensional dan dimensional. B.English The utility of turbine is very wide, according to the function of turbine designed in special form to be able to perform this function, one of which the function is the turbine can be used as expansion turbine on air cycle machine that used as air cooling system in aircraft cabin. The design of a single stage radial turbine as an expansion turbine with easy and inexpensive production and high efficiency. This design begins with calculating the initial design parameters and continued with the design steps of designing the turbine impeller, inlet turbine nozzles and turbine scroll. Turbine design parameters derived from calculations include non-dimensional and dimensional parameters.

Abstract

The moving process requires that the aircraft be separated into several sections to accommodate the kind of transporter. In order to the aircraft can be used as training aids in program studi Teknik Pesawat Udara (TPU) need to be done re-installation of parts that have been removed when the moving process. One of the parts to be reinstalled is the hoses and pipes. Because the inadequate detailed reinstalling guidelines for hose and pipe reinstallation and storage of aircraft parts is poorly controlled when the moving process, it’s resulted many parts of the aircraft that are not in a group of systems require an analysis of the processing stage or the installation process of the Queen Air B80 aircraft hose and pipe. Based on results of performed analysis, the stages for reinstall Queen Air B80 aircraft hose and pipe are collects the available aircraft documents, after that checks all the existing parts and collects into its system and then checked the condition of the parts carefully and found the number of existing and missing parts. After that make list of available and unavailable component and continued with make the installation stage of hose and pipe into the form of task card.
