Abstract
"MéTODO E APARELHO PARA PREVENçãO DE EFEITOS ADVERSOS DE ESTADO DE ANEL DE VóRTICE". Um sistema de controle de vóo para uma aeronave de rotor para impedir os efeitos adversos do estado de anel de vórtice é revelado. No sistema de controle de vóo da invenção, as admissões de controle selecionadas são enviadas para a aeronave, de rotor antes do começo do estado de anel de vórtice. Na concretização preferida, as admissões de controle são transientes, não requerem admissão a partir do piloto, e não afetam a trajetória de vóo da aeronave de rotor.
