Projeto conceitual de um equipamento de apoio no solo dedicado a motores turboshaft

Abstract

Aircraft Maintenance Facilities that have been certi ed as MRO (Maintenance, Repair and Overhaul) centres where maintenance procedures such as general revision, minor repairs of systems, subsystems and aeronautical components are carried out, including the overhaul of engines and propellers which are performed in line. It is the case of the CMR center of the company Vertical, where a problem in the maintenance process of the Klimov TV3-117 engine was identi ed due to the di culties in the stage of handling and rotation of the unit, as its weigth is in the range between 250 and 350 kg, often causing delay in the stipulated time for each operation, therefore increasing the overal costs for the operator. By means of computer modelling, a CAD software was used in order to carry an applied research for the conceptual projection and the structural analisis of the design. This research has as a result the conception and the structural viability study of the prototype for a ground support equipment for handling and maintenance of a turboshaft engine, with whose implementation would enable the saving of 100 man-hours of labour, as four specialised operators and two inspectors are needed when conventional support systems are used for the overhaul of the engine, and with this new design, only one of each would be needed instead. All this adds up to an amount of about $10 000 being saved per overhauled engine.
