Abstract

"SISTEMA DE CONTROLE DE AERONAVE DE ROTOR COM LIGAçãO DE MISTURA ESCALONADA". Um sistema de controle para uma aeronave de rotor é revelado. O sistema de controle inclui uma ligação de mistura escalonada, tal que uma quantidade selecionada de saída de cíclico lateral esquerda-direita é gerada para certas quantidades de entrada de cíclico em direção à popa. A ligação de mistura escalonada inclui duas ligações de suporte e uma ligação flutuante articuladamente acoplada entre as duas ligações de suporte. A razão dos comprimentos das duas ligações de suporte para o comprimento da ligação flutuante é pequena, gerando, desse modo, uma saída senoidal lateral selecionada, uma rotação selecionada da saída senoidal, e uma saída com rampa selecionada em resposta a cada comendo de entrada de piloto em direção à popa.
