这一架构的核心思路，是利用电机来“抚平”热机的功率曲线，从而让燃气涡轮更多时间工作在高效区间。 起飞、爬升等需要高功率输出的阶段，可由电机提供额外推力支援，使涡桨发动机无需频繁大幅提转、降转；巡航阶段则以较为恒定、优化的节流状态工作。 在飞行员操作层面，这套系统可以在需要时将总输出推高至2兆瓦，让推力储备更加充足。
If you’ve ever watched a Taylor Swift ticket disappear from your cart at the last second, stared at a frozen Ticketmaster screen, or refreshed a Resy page only to see that 7 p.m. table vanish in a blink, Kessler has studied the strange form of economic activity.
