Electric aircraft propulsion has the potential to revolutionize the aerospace industry, by reducing the fuel burn,**emissions, noise, and improve the aircraft performance. The interest for this technology has increased in the**last couple of years with the development of vertical take off and landing aircraft with a large number of**propulsors and very short missions. While the battery technology matures, hybrid-electric propulsion is seen as**an enabler to improve range, while taking advantage of some of the benefits from electric propulsion. In a**parallel-hybrid architecture, an electric motor is used to add or extract power from a conventional gas turbine**and its propulsion system. In a series-hybrid architecture, the propulsion system is driven by an electric motor,**and the electricity is provided by a generator and a gas turbine.**The focus of this research project is to compare parallel-hybrid and series-hybrid propulsion architecture for a**variety of conventional aircraft, including a regional transport aircraft (40 pax), a commuter aircraft (8 pax),**and a modern rotorcraft. For each type of aircraft, each type of propulsion architecture will be optimized and**compared to minimize fuel burn or direct operating cost for a predefined mission given today's technologies**and future technologies. A system-level mission simulation will be developed to analyze the aircraft**performance throughout each mission phase. While there is a target mission defined in terms of range or**endurance, the optimization process will also vary the mission profile, including cruise altitude and the**climb/descent profile to maximize the benefits of the hybrid propulsion powertrain.**This research project will benefit the industrial partner, with the identification of the most promissing market**for the development of hybrid propulsion for more conventional aircraft

电动飞机推进力有可能通过减少燃油燃烧，**排放，噪音并改善飞机性能来彻底改变航空航天行业。在过去的几年中，随着垂直起飞和降落飞机的开发，对这项技术的兴趣增加了，并使用了大量的**推进器和非常短的任务。虽然电池技术成熟，但混合电力推进被视为**可以提高范围的推动力，同时利用电动推进的某些好处。在**平行混合体架构中，电动机用于从常规燃气轮机**及其推进系统中添加或提取电源。在系列杂交建筑中，推进系统由电动机驱动**，并且电力由发电机和燃气轮机提供。各种常规飞机的推进架构，包括区域运输飞机（40 pax），通勤飞机（8 pax），**和现代旋翼飞机。对于每种类型的飞机，与最小化燃油燃烧或直接操作成本相比，每种类型的推进体系结构都将在当今的技术**和未来技术的情况下最小化燃油燃烧或直接操作成本。将开发系统级任务模拟，以分析每个任务阶段的飞机**性能。尽管有一个目标任务在范围或**耐力方面定义了，但优化过程也将改变任务概况，包括巡航高度和**攀爬/下降概况，以最大程度地提高混合推进动力总成的好处。研究项目将使工业合作伙伴受益，并确定最高票的市场**用于开发混合动力推进，以进行更常规的飞机
