“黑鹰”直升机的新型旋翼桨叶

New Main Rotor Blade of Black Hawk

设计目的“黑鹰”直升机空重和有效载重的不断增加将导致其机动能力、高速飞行性能和失速特性的降低。西科斯基公司投资研制的新型复合材料桨叶以及对旋翼的其它改进对提高现有“黑鹰”及新改型“黑鹰”直升机的机动性、高速飞行性能及失速性能将大有收益。 “黑鹰”直升机的原型UH-6OA设计起飞总重为7485千克、最大总重为9185千克。而目前美国陆军所使用的标准型UH-6OL。

The new blade and several main rotor improvements will grow Black Hawk helicopter 's empty weight and payload capability and regain maneuver, high speed flight as well as stall performance . Sikorsky Aircraft is testing the new blade. The new blade and rotor design could become standard equipment on production Black Hawk as early as 1997 andcould be used in next series types of Black Hawk .
