Abstract

método para a detecção automática da ingestão de pelo menos um corpo estranho por meio de um motor de turbina a gás. a invenção se refere a um método para a detecção automática da ingestão de pelo menos um corpo estranho por meio de um motor de turbina a gás, de acordo coma qual: a velocidade instatânea do rotor (r(t) é medida; o sinal de velocidade do rotor (r(t) é filtrado a fim de separar o componente estático (rs(t) a partir do seu componente dinâmico (rd(t); o componente dinâmico filtrado (rd(r) é comparado a uma onda de ressonância padrão (e(t) do rotor a fim de se obter um indicador da ingestão (ting), a onda de ressonância padrão (e(t) correspondente à resposta ao impulso vibracional de um rotor; o indicaodr da ingestão obtido (ting) é comparado com um início da detecção (s); e um sinal de detecção de ingestão do corpo estranho é emitido quando o indicador da ingestão (ting) é maior do que o início da detecção (s).
