Abstract

um reversor de empuxo para uma nacela de motor turbojato, compreendendo capotas móveis (10) que se movem para trás em relação a um quadro frontal (2) sob a ação de um sistema de atuação, deste modo, fazendo os flaps (8) virar, por meio de um mecanismo de controle, de modo a fechar substancialmente a via de fluxo de ar feio anular (4), e ao abrir as cascatas (12) dispostas em torno desta via de fluxo e que recebem o fluxo de ar frio e o retornam para frente, caracterizado pelo fato de que o reversor de empuxo estando fechado, as cascatas (12) são parcialmente integradas com as capotas (10), e de que esse inclui um sistema de atuação que faz com que as cascatas se movam para trás ao longo de um curso que é mais curto do que o curso da capota.
