XV-24雷击无人机(英语:LightningStrike)是一款由奥罗拉飞行科学公司英语Aurora Flight Sciences和其伙伴劳斯莱斯以及霍尼韦尔共同研制的垂直起降实验无人机。[1]

发展

2016年3月3日,国防高等研究计划署拨款奥罗拉飞行科学公司8,940万美元,用于建造雷击无人机。垂直起降实验机(英语:VTOL X-Plane)的计划第二阶段将于2018年9月之前制造两架原型机。[2][3][4][5][6] 首先完工一架20%比例重325lb(147kg)的示范机,机翼和鸭翼由碳复合材料英语Reinforced carbon–carbon3D打印制成,并于2016年3月29日首飞。[7][8]全尺寸飞机将被命名为 XV-24A。[9]

2018年4月,在小型验证机实现VTOL X-Plane主要目标后,国防高等研究计划署在飞行测试前取消了该项目。[10]

设计

雷击无人机采用倾斜翼设计,并采用与V-22鱼鹰式倾斜旋翼机相同的劳斯莱斯AE1107C涡轮轴发动机提供动力,通过三台霍尼韦尔发电机发电驱动24个(前翼各3个、主翼18个)分布式涵道风扇。该机使用“分布式电力推进”,其中三台发电机可产生3兆瓦(4,023 马力)的电力,相当于商用风力涡轮机,为驱动风扇的单独马达提供动力; 每个翼式风扇使用100kW电机,每个鸭式风扇使用70 kW电机。雷击无人机的重量在10,000–12,000lb(4,500–5,400kg)之间,大约相当于UH-1Y毒液直升机,巡航速度超过300knots。
