Thermal Management for the Hybrid Electric Regional Aircraft

TheMa 4 HERA项目承担了机载热管理的巨大挑战，这是在支线和中短程飞机中引入混合动力和推进系统所带来的。这将通过在TRL 5开发，设计和测试从空气供应到空调，系统热管理到机舱空气分配的各种创新技术来实现。而今天的热管理系统需要处理约35- 50千瓦的散热，明天的混合动力支线飞机将不得不处理300至1.000千瓦的散热范围！该项目由热管理市场上所有主要航空航天参与者组成，将解决几乎所有目前已知的热管理技术。将建立与TRA-01的多个双向交互回路，以满足集成要求、反馈约束和验证结果，从而允许进一步的飞机结构优化迭代。通过开发全数字孪生模型，该项目将能够模拟和优化任何给定飞机架构的组件级需求。该架构将取自EXACT项目，在整个项目中进行调整和完善，最终反映最终的混合动力飞机架构。该项目将在Fraunhofer IBP的全尺寸演示测试设施中验证和展示其结果。届时将有进一步完善的模型，该项目还将能够计算实现预期成果的成就，特别是环境足迹。沟通、传播和开发行动将确保所有必要的利益相关者也将支持首架基于TheMa 4 HERA热管理技术的混合动力支线飞机的EIS。

The TheMa4HERA project takes on the huge challenge of on-board thermal management that comes with the introduction of hybrid electric power and propulsion systems in Regional and Short and Medium Range aircraft. This will be achieved through development, design and testing at TRL 5 of wide range of innovative technologies from Air Supply, to Air Conditioning, Systems Thermal Management to Cabin Air Distribution. Whereas today’s thermal management systems need to handle a heat dissipation of about 35-50kW, tomorrow’s hybrid electric regional aircraft will have to handle heat dissipation in the range of 300 to 1.000kW! With a consortium composed out of all key aerospace players in the market of thermal management, this project will address almost all currently known thermal management technologies. Multiple two-way interactions loops with TRA-01 will be established integration requirements and feedback constraints and validation results, to allow for further aircraft architecture optimization iterations. Through the development of a full digital twin, the project will be able to simulate and optimize component level requirements for any given aircraft architecture. This architecture will be taken from the EXACT project, adjusted and refined throughout the project, to eventually reflect the final Hybrid Electric Aircraft architecture. The project will validate and demonstrate its results in a full-scale demonstration test facility at Fraunhofer IBP. With the further refined models, that will be available by then, the project will also be able to calculate the achievements towards the Expected Outcomes, in particular the environmental footprint. The Communication, Dissemination and Exploitation actions will make sure that all necessary stakeholders will also be supportive to the EIS of the first Hybrid Electric Regional Aircraft relying on TheMa4HERA thermal management technologies.
