Abstract

BOCAL DE VENTOINHA DE áREA VARIáVEL, SISTEMA DE MOTOR DE TURBINA A GáS, E, MéTODO PARA CONTROLAR UMA áREA EFETIVA ASSOCIADA à SEçãO DE BOCAL VARIáVEL DE UM MOTOR DE TURBINA A GáS. Um bocal de ventoinha de área variável para uso com um sistema de motor de turbina a gás inclui uma seção de bocal que é móvel entre uma pluralidade de posições para mudar uma área efetiva associada a um fluxo de ar de desvio através de uma passagem de desvio de ventoinha de um motor de turbina a gás. Uma cobertura protetora é disposta na seção de bocal e resiste à mudança na área efetiva da seção de bocal causada por condições ambientais.
