随着X-57 Mod II初具规模，标志着全电动飞机发展的新里程碑
作为综合旋转测试的一部分，X-57 Mod II全电动飞机的电动机和螺旋桨将首次通电并一起旋转。Scaled Composites的项目工程师克里斯•希格比(Chris Higbee)出现在Mod II型飞机的驾驶舱里。背景中沿着山坡看到的风力涡轮机展现了全电动飞机未来的景象，未来X-57的最终阶段被称为Mod IV，它的机翼将集成12个发动机舱，最终将容纳12个小型电动高扬程电机和螺旋桨。
The electric motors for X-57’s Mod II vehicle and their propellers were powered up and spun together for the first time as part of an integrated spin test. Chris Higbee, Project Engineer at Scaled Composites, is seen in the cockpit of the Mod II vehicle, which is the aircraft’s first of three electric configurations. The wind turbines seen along the hillside in the background illustrate an impression of the future final phase of X-57, known as Mod IV, which will feature 12 small electric high-lift motors and propellers along its wing.
