Question

求助大侠帮忙翻译

The airframe manufacturer reported that windmilling flight tests were successfully demonstrated at airspeeds as low as 240 knots with N2 windmilling rotor speeds as low as 8%

Answer 1

直译：
飞机制造商报告说 以螺旋桨转速低至8%（的状态飞行）飞行速度会低至240节，这在螺旋桨的飞行测试中已经被成功地证实了
意译：
飞机制造商报告说，螺旋桨飞行测试成功地证实了在螺旋桨转速低至仅余8%时，飞机的空速会随之低至240节。

大概意思应该是这样吧，不是很确定呵
