Electric-hybrid flight has the potential to drastically reduce fuel consumption and emissions of aircrafts, as well**as enabling completely new markets. Parallel hybrid architectures could reduce fuel consumption while using**existing airframes by downsizing the turbine and providing the additional power required during transients with**batteries. Series hybrid, combined with new airframes, opens even greater opportunities by allowing large**differences between take-off power and cruise power without losses in efficiencies experienced in conventional**systems due to poor off-design gas turbine performance.**Pratt & Whitney Canada (PWC) is currently exploring the emerging electric-hybrid aircraft market to identify**the opportunities for performance improvements, with a focus on series hybrid architecture. While there is a**considerable "hype" around electric and electric-hybrid aircrafts, there is limited scientific literature and**reliable data on the actual achievable performance. Most of the studies rely on futuristic values for battery**energy density (up to 4 times that of current state-of-the-art battery technology) and manufacturers claim**optimistic transient power rating of electric motors.**PWC has approached Createk Design Lab at Université de Sherbrooke to assess the performance of series**hybrid aircrafts. Prof. Picard's team within Createk is currently developing technologies for electric-hybrid**aircrafts - including a ceramic microturbine, a high-speed electric generator and low-drag ducted fans - as well**as models to evaluate the benefits of these technologies on the aircraft mission. Building on this experience,**Prof. Picard will carry this ENGAGE project to compare the actual performance of an electric-hybrid aircraft to**ideal performance predictions using a first-order digital twin model to simulate a regional transport mission.

电动混合动力飞行有可能极大地降低飞机的燃油消耗和排放，并**为全新的市场创造条件。并行混合架构可以在使用**现有机身的同时减少燃料消耗，方法是缩小涡轮机的尺寸，并在使用**电池的瞬变过程中提供所需的额外功率。系列混合动力飞机与新机身相结合，带来了更大的机会，使起飞动力和巡航动力之间的巨大**差异不会因燃气轮机设计外性能差而损失传统**系统的效率。**普惠加拿大公司(PWC)目前正在探索新兴的电动混合动力飞机市场，以确定**性能改进的机会，重点是系列混合动力体系结构。虽然围绕电动和电动混合动力飞机有相当大的“炒作”，但关于实际可实现的性能，科学文献和可靠数据有限。大多数研究依赖于电池**能量密度的未来值(高达当前最先进电池技术的4倍)，制造商声称**乐观的电动马达瞬时功率额定。**普华永道已与舍布鲁克大学的Createk设计实验室联系，评估系列**混合动力飞机的性能。皮卡德教授在Createk的团队目前正在为电动混合动力飞机**开发技术--包括陶瓷微型涡轮机、高速发电机和低阻力导管风扇--以及评估这些技术在飞机任务中的益处的模型。在这一经验的基础上，**皮卡德教授将开展这个Engage项目，将电动混合动力飞机的实际性能与**使用一阶数字孪生模型模拟区域运输任务的理想性能预测进行比较。
