Abstract

calota de translação e aparelhos. trata-se de uma calota de translação para um motor a jato que inclui um chevron acoplado a um atuador linear. o chevron pode ser movido pelo atuador linear para frente e para trás para mudar uma trajetória de fluxo de gás formada uma calota de núcleo e calota de translação do inversor de empuxo. em uma primeira posição, os chevrons são dispostos substancialmente paralelos à trajetória de fluxo de gás para atenuar o arraste e/ou perda de empuxo do motor. em uma segunda posição, os chevrons são movidos para trás para projetar, ou projetar adicionalmente, dentro da trajetória de fluxo de gás. em uma modalidade, o atuador linear compreende um primeiro componente que é acoplado à calota externa. um segundo componente do atuador linear é acoplado ao chevron. quando instalado, o atuador linear pode ser acoplado a um controlador e uma fonte de energia elétrica. um sensor de posição acoplado ao controlador percebe uma posição do atuador linear e/ou chevron.
