Implementação de um banco de teste do APU do avião Bombardier modelo DHC-8, Q-400 na empresa LAM – Linhas Aéreas de Moçambique

Abstract

This work has as object the implementation of a Test Bench for Bombardier Model DHC 8, Q-400 Aircraft APU – Auxiliar Power Unit. For best understanding, firstly is referred the function of the APU in the Aircraft, followed by the blocks diagram and the function description of each block in the APU system. In the following point, is described the operation of the APU and are identified de parameters to be considered in the test and its limits, fixed by the manufacturer. Ahead, are described the constructive parts of APU Teste Bench and the electrical circuits connecting the control devices of the APU under teste. In this part of the work, else are presented the mechanisms simulation of faults in APU operation and its indication. Even more, is presented the list of the needed material and the related coast for APU Teste Bench implementation and the necessary equipment to perform the test. In the end of this report, are taken conclusions and recommendations are given, about economic viability of Bombardier Model DHC-8, Q-400 fleet APU, in the LAM – Linhas Aéreas de Moçambique, SA company.
