Hybrid-electric propulsion has the potential to reduce the fuel consumption of transport aircraft while being much more realistic than full-electric aircraft for conventional missions for the foreseeable future. One potential powertrain architecture is the parallel hybrid-electric system. A generator/motor is added in parallel to conventional turboshaft engines to supplement the engine on the ground or in flight during specific phases. By reducting the gas turbine operation at low efficiency, such as near-idle, a reduction in fuel burn near 30% can be achieved, thus reducing emissions and operating cost. This research project aims at developing the key knowledge to explore and optimize parallel-hybrid electric propulsion for turboprop regional aircraft, both for single and multiengine aircraft configuration. Hybrid-electric powertrain optimization is complex since it is highly coupled with the aircraft, it requires detailed thermal simulation, and no historical trends can support the design process. A parametric, time-marching aircraft and powertrain simulator (second timescale) will be developed to analyse and optimize the system throughout the mission. The simulator will consider failure analysis, thermal management, transient mechanical response, various environmental conditions and mission profiles. In particular, the optimal solutions should comply to current and expected future regulation, such as the available reserve and missed approach. To improve the visualization and exploration of the optimal solutions, this project includes the generation of multidimensional pareto frontiers. The researchers will also perform a detailed electrical simulations (milisecond timescale) to identify potential challenges of the hybrid architecture and identify mitigation actions. Experimental test on an integrated 30 kW and 150 kW test bed will validate individual models. This research projet will benefit Canada as it will provide new business opportunities for Pratt and Whitney Canada (PWC), which aims at commercializing the technology based on the research results in the coming years.

混合电气推进有可能减少运输飞机的燃油消耗，同时比全电动飞机在可预见的未来进行传统任务更现实。潜在的动力总成架构是并行混合电动系统。与常规的涡轮轴发动机并行添加发电机/电动机，以补充特定阶段的地面或飞行中的发动机。通过以低效率（例如近事件）减少燃气轮机运行，可以减少燃料燃烧接近30％的速度，从而降低排放和运营成本。 该研究项目旨在开发关键知识，以探索和优化涡轮螺旋桨飞机的平行杂交电动推进，用于单台和多发动机配置。混合电动动力总成优化非常复杂，因为它与飞机高度相结合，需要详细的热模拟，并且没有历史趋势可以支持设计过程。 将开发一个参数，时间建设的飞机和动力总成模拟器（第二次尺度），以在整个任务中分析和优化系统。模拟器将考虑故障分析，热管理，瞬态机械响应，各种环境条件和任务概况。特别是，最佳解决方案应遵守当前和预期的未来法规，例如可用的储备和错过的方法。为了改善最佳解决方案的可视化和探索，该项目包括生成多维帕累托前沿。研究人员还将执行详细的电气模拟（MILISECOND TIMESCALE），以确定混合体系结构的潜在挑战并确定缓解措施。在综合30 kW和150 kW测试床上进行的实验测试将验证单个模型。这项研究将使加拿大受益，因为它将为Pratt和Whitney Canada（PWC）提供新的商机，该公司旨在根​​据未来几年的研究结果将技术商业化。
