Abstract
Patente de Invenção: <B>"PALHETA DE ESTATOR VARIáVEL à PROVA DE DESCASAMENTO"<D>. Uma palheta de estator variável (14) inclui um aerofólio, que possui uma haste rosqueada (20), uma alavanca (22) que possui um furo de montagem (28) que recebe a haste (20) e uma porca que engata a haste (20) por rosqueamento a fim de reter a alavanca sobre o aerofólio (14). é formada uma folga entre a sede e a alavanca (22) durante o alinhamento entre as mesmas, a fim de prover superposição de rosca suficiente entre a porca e a haste para permitir engate entre as mesmas, sendo produzida superposição de rosca insuficiente durante o desalinhamento para impedir engate rosqueado entre as mesmas.
