The invention provides a C-shaped flow guide wall for a narrow machine body ground test run, which comprises an arc-shaped section flow guide wall, and the arc length of the arc-shaped section flow guide wall is 51868-66996 mm; the chord width of the arc-shaped section flow guide wall is 50080-64415 mm, the width of the narrow-body aircraft body is smaller than 4.72 m, the narrow-body aircraft body can fully cover airflow generated by an aircraft engine with the diffusion angle of +/-35 degrees, the length of the arc-shaped section flow guide wall can cover reflected airflow with the diffusion angle of +/-35 degrees, and the reflected airflow of the aircraft engine approaches the aircraft. Therefore, airflow impact on workers or buildings in a safe area is avoided, and the test run safety is ensured during test run.

    本发明提供一种窄机体地面试车用C型导流墙,包括弧形段导流墙,所述弧形段导流墙的弧长为51868‑66996mm;弧形段导流墙的弦宽为50080‑64415mm,窄体机机身的宽度小于4.72m,能全覆盖扩散角度为±35°的飞机发动机产生的气流,使得弧形段导流墙的长度能覆盖扩散角度为±35°的反射气流,使得飞机的发动机的反射气流向飞机靠近;进而不会对安全区域的工作人员或建筑造成气流冲击,在进行试车时保证试车的安全性。
