今年4月初,一架租给路易斯安那太平洋公司的K-MAX直升机,在加州现场伐木作业时,由于直升机太靠近树木,右旋翼打到一棵直径约90厘米的大树,一片桨叶被打掉76厘米,另一片“桨叶被打掉33厘米,但飞行员却设法将吊挂的2300千克重的木头放下,并继续飞了400多米,3分钟后安全降落在原集结区.飞行员安然无恙,创造了直升机伐木史上桨叶严重断裂、安全返陆的奇迹.虽然K-MAX直升机旋翼的气动性能和直升机的操作性能和自身的平衡性能都很突出,但在如此严重失衡状态下,飞行
In early April of this year, a K-MAX helicopter leased to the Louisiana Pacific Corps was logging trees in California. Because the helicopter was too close to the trees, the right-hand rotor hit a tree about 90 cm in diameter. A blade was The other piece, “The blade was knocked 33 centimeters, but the pilot tried to put down 2,300 kilos of hanging wood and continued to fly more than 400 meters, safely landed in the original assembly area after 3 minutes.” The pilot was safe and sound, Creating a miracle of serious blade rupture and safe return of helicopter logging history.Although the K-MAX helicopter rotor aerodynamic performance and helicopter operating performance and its own balance performance are outstanding, but in such a serious imbalance, the flight
