The invention provides a wide machine body ground test run C-shaped guide wall which comprises an arc-shaped section guide wall, and the arc length of the arc-shaped section guide wall is 90769-129669 mm; the chord width of the arc-shaped section flow guide wall is 86509-121115 mm, the arc-shaped section flow guide wall 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 approaches an aircraft; therefore, airflow impact on workers or buildings in a safe area is avoided, and the test run safety is ensured during test run.
本发明提供一种宽机体地面试车用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90769‑129669mm;弧形段导流墙的弦宽为86509‑121115mm,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。
