中国载荷1.5吨“大块头”无人机首飞 可一键自主起降

据新华社电 有效载荷1.5吨,可“一键操控”在200米内完成起降——由中国科学院工程热物理研究所等单位联合研发的大型货运无人机AT200近日成功首飞,是目前世界上民用无人机领域首屈一指的“大块头”。

26日,AT200在陕西蒲城内府机场首飞。飞机经过滑跑、起飞、爬升至预定高度后,进入巡航段并盘旋两周,随后进入着陆航线平稳着陆,整个飞行过程持续26分钟。

专家介绍,AT200摆脱了对飞行员的依赖,在指控中心即可实现飞机“一键自主起降”,还可同时控制多架无人机。其间只需监控无人机的状态,必要时由无人机飞控手进行简单操作即可改变飞行状态,极大地降低了货运成本和无人机操作难度。

记者从中科院工程热物理所了解到,AT200最大起飞重量3.4吨,货仓容积为10立方米,有效载荷达1.5吨,相当于一辆小货车的载重。巡航速度为313公里/小时,续航时间8小时、航程2183公里,实用升限达6098米。飞机满载时可在200米内完成起降。

AT200以新西兰生产的P750XL为原型机进行无人化研发设计,突破了有人机改无人机总体设计、飞机-发动机-控制系统匹配、飞机气动参数辨识、全机质量特性测试和系统综合测试等关键技术,验证了大型固定翼有人机无人化的可行性。
