THE NEED: Air transport policies and aircraft manufacturers and operators demand for leaner, greener and safer aircraft transport systems as well as reduced development and operating costs has resulted in a need for a paradigm shift in aircraft design. The most promising approach to meet these targets is based on improving the global operational aircraft efficiency. To this end, the adoption of high aspect ratio configurations, lighter and tailored composites to increase payload, energy efficient propulsion systems, and advanced manufacturing has received considerable attention in the research community.  Despite the great technological improvements in the fields of emissions and noise reduction, similarities in both shape and configuration in current designs are evident because conventional configurations are optimized for cruise. Outside this range, aircraft performance is far from the optimal. Since the vast majority of commercial aircraft fly mostly in cruise, only with technology breakthroughs it will be possible to significantly increase efficiency. PROPOSED PROGRAM: The research program aims to improve the performance of complex multidisciplinary engineering systems through advances in mathematical and computational models, and experimental methods. The primary objective is to connect emerging mathematical models and enabling technologies with new designs and concepts of operations to achieve "Leaner, Greener and Safer" air transportation. From a greening perspective, aircraft propulsion technology is currently transitioning to cleaner, more efficient, and quieter solutions. Hybrid electric propulsion systems offer several potential benefits over conventional systems including a smaller environmental footprint, reduced fuel consumption, longer endurance and novel distributed propulsion architectures. The research program aims to develop models to quantify the performance of hybrid propulsion systems and validate and evaluate the computational models, first in a controlled laboratory setting, and finally test the architectures in flight using Unmanned Aerial Systems (UAS). From a safety perspective, the research program will continue to focus on structural health monitoring of aircraft composite structures as a continuation of the preceding NSERC DG. It aims to develop structural health monitoring procedures using progressive fatigue damage models based on strain and thermoelastic measurements. BENEFITS: The proposed research program will exploit the knowledge, expertise and experimental facilities at the Center for Aerospace Research in `design, build, test and fly' of UAS to buttress the development of green and safe aviation and related technologies. The proposed scientific methods and processes are both leading-edge academically and balanced for potential near-term industrial applications. The program will also provide exciting opportunities for training of HQP in areas of critical importance to the Canadian aerospace sector.

需求：航空运输政策以及飞机制造商和运营商对更精简、更环保和更安全的飞机运输系统以及降低开发和运营成本的需求导致需要对飞机设计进行范式转变，以实现这些目标。为此，采用高展弦比配置、更轻和定制的复合材料来增加有效载荷、节能推进系统和先进制造已受到研究界的广泛关注。排放领域的技术改进降噪方面，当前设计在形状和配置上的相似性是显而易见的，因为传统配置是针对巡航进行优化的，飞机性能远非最佳，因为绝大多数商用飞机主要在巡航中飞行，只有在技术突破的情况下。拟议的计划将有可能显着提高效率：该研究计划旨在通过数学和计算模型以及实验方法的进步来提高复杂的多学科工程系统的性能。新的设计和操作理念来实现“更精简、更环保、更安全”的航空运输从环保角度来看，飞机推进技术目前正在向更清洁、更高效、更安静的解决方案过渡，与传统系统相比，混合电力推进系统具有多种潜在优势，包括更小的环境足迹、更少的燃料。该研究计划旨在开发模型来量化混合动力推进系统的性能，并首先在受控实验室环境中验证和评估计算模型，最后使用无人机在飞行中测试该架构。从安全角度来看，该研究项目将继续关注飞机复合材料结构的结构健康监测，作为之前 NSERC DG 的延续，旨在使用基于渐进式疲劳损伤模型的结构健康监测程序。优点：拟议的研究计划将利用航空航天研究中心在无人机“设计、建造、测试和飞行”方面的知识、专业知识和实验设施，以支持绿色和安全航空及相关技术的发展。 。拟议的科学方法和流程在学术上均处于领先地位，并且与潜在的近期工业应用相平衡，该计划还将为加拿大航空航天业至关重要的领域的 HQP 培训提供令人兴奋的机会。
