Abstract

SELO AERODINáMICO PARA REDUçãO DO RUìDO GERADO POR SUPERFìCIES DE CONTROLE DE AERONAVES Os mecanismos de ruído das extremidades laterais de flapes têm sido objeto de um grande número de estudos durante as últimas décadas. Um sistema de vértice específico emana da extremidade lateral da ponta de um flape devido à diferença de pressão estática entre as superfícies superiores e interiores do flape. Tal diferença de pressão conduz a uma fusão (mistura) entre os dois sistemas de vértice que são gerados nas extremidades superiores e inferiores do contorno lateral do flape. A presente invenção propõe a aplicação de um selo perfurado (21) no bordo lateral inferior (11) e/ou superior (8) do contorno de uma superfície de controle tal como um flape (3), com o propósito de agir como um gerador de vértice, tornando difícil para o sistema de vértice inferior se mover para cima e fundir-se com o sistema de vértice superior. Os selos em lâmina perfurada (21) ficam dispostos preferivelmente nas extremidades internas e externas de flapes de alta sustentação (3).
