英国科学家破解1600年前罗马变色玻璃之谜 成功重现古代琉璃杯的光学效果

御风未来展示M1载人电动垂直起降飞行器

御风未来在第九届进博会上展出M1真机。按展台公布参数，飞行器最大起飞重量为2.5吨，最大载重700公斤，可搭载五名乘客。机上配置四个前拉旋翼和十六个垂直起降旋翼，采用纯电驱动，标称续航250公里，巡航速度为每小时200公里。它无需传统跑道即可起降，面向城市通勤与中短途城际出行。

企业设想的主要运行空域高度为300至3000米，并将上海会展中心至张江、临港或苏州等地列为潜在应用场景。现场所述航程、载重和速度是产品参数，不能当成目前已有航班的时刻表。御风未来预计在2028至2029年取得载人适航证，并争取于2030年前后开展固定航线客运。适航批准和正式运营仍是后续节点，本次对外开放的是展台上的真机及模拟体验。企业表示，机上多个动力单元分别承担推力，方案支持自主飞行。
