The present invention relates to a back pressure adjustment apparatus of an air intake of an aircraft for adjusting the back pressure of an exit side of an air intake of an aircraft including a ramp, a sidewall, a cowl, and an isolation part. The back pressure adjustment apparatus comprises an indirect variable nozzle which is coupled to the rear end of the isolation part or to the end of a pitot pressure measurement rake part extending from the isolation part, wherein the indirect variable nozzle is coupled to the rear end of the isolation part or to the end of the pitot pressure measurement rake part by a hinge to be rotatable, thereby adjusting an exit area of the intake. According to the present invention, the back pressure adjustment apparatus can protect a driving part of the back pressure adjustment apparatus from being exposed to high-temperature environments and can immediately identify the start-up limit of the intake.

    본 발명은 램프(ramp), 격벽(sidewall), 카울(cowl), 격리부를 포함하는 비행체의 흡입구의 출구 측 배압(back pressure)을 조정하기 위한 장치로서, 상기 격리부 후단 또는 상기 격리부로부터 연장 형성된 피토 압력 측정 레이크 부의 끝단에 결합되는 간접 가변 노즐을 포함하고, 상기 간접 가변 노즐은 상기 격리부 후단 또는 상기 피토 압력 측정 레이크 부의 끝단에 힌지에 의해 회전 가능하게 결합됨으로써, 상기 흡입구의 출구 면적을 조정 가능한 것을 특징으로 하는 비행체 흡입구의 배압 조정 장치로서, 본 발명에 의하면, 배압 조정 장치의 구동부를 고온 환경에 노출되지 않도록 보호 가능하며, 흡입구의 시동 한계를 즉각적으로 파악 가능하게 한다.
