Abstract

processo para controlar empuxo de marcha lenta de um turbojato, meio de dados legível por computador, dispositivo de controle, e, turbojato. processo de acordo com a invenção para controle de um empuxo de um motor turbojato, tendo fluxo de combustível regulado por meio de um batente superior para proteção contra bombeamento de um compressor do motor do turbojato, que compreende: - obter (e10) um primeiro valor de empuxo correspondendo a um primeiro ponto de operação do compressor no batente superior, este batente superior levando em consideração uma subestimação do fluxo de combustível; - controlar (e20) o motor do turbojato para atingir o primeiro valor de empuxo; - monitorar (e30) o motor do turbojato para detectar um afrouxamento do compressor; - se necessário: obter (e10) um segundo valor de empuxo correspondendo a um segundo ponto de operação garantindo uma margem predeterminada com relação ao batente superior para proteção contra afrouxamento do motor do turbojato; e controlar (e50) o motor do turbojato para atingir o segundo valor.
