Abstract

"CONJUNTO DE ASA AERONAVE, AERONAVE, DISPOSITIVO DE HIPERSUSTENTAçãO DE BORDA DIANTEIRA, E, PROCESSO PARA REDUçãO DO ARRASTO ASSOCIADO COM UMA ASA DE AERONAVE". Trata-se de uma asa de aeronave, um conjunto de asa e um processo para redução de arrasto. O conjunto de asa inclui uma parte de asa principal (10) e uma parte de hipersustentação (12) de borda dianteira. A parte de hipersustentação é móvel entre uma posição retraída na qual se funde geralmente com a parte de asa principal e uma posição operacional para diante daquela. Pelo menos uma parte substancial de uma superfície superior (22) da parte de hipersustentação é permeável ao ar ou perfurada e encontra-se em comunicação fluida com uma passagem de sucção (30) na mesma. Durante o vóo, pode ser aplicada uma sucção à passagem de sucção para redução da extensão de sentido de corda da camada limítrofe turbulenta sobre a superfície superior ou a superfície inferior da asa.
