Abstract

"CONFIGURAçãO DE UMA AERONAVE". Uma aeronave (10), em particular uma aeronave de treinamento com melhor desempenho aerodinâmico, que tem uma configuração capaz de manter uma estabilidade direcional e um comportamento aerodinâmico muito bom, mesmo em ângulos de ataque muito grandes, onde configurações tradicionais têm demonstrado ser ineficientes. Em particular, esta configuração prevê um nariz (52) com seção variável, otimizada para vóos em grandes ângulos de ataque, um dispositivo de controle de vórtice de LEX (72) pelo menos uma admissão de ar sem desvio (46), e um perfil de asa (18, 20) otimizado a fim de reduzir os efeitos de vibração típicos de asas com baixa relação de aspecto com perfil delgado e abaulamento variável. A aeronave (10) apresenta, finalmente, caudas desalinhadas entre si (44 e 38) de forma a otimizar o desempenho aerodinâmico.
