摘要

Drone Mermoz 项目旨在评估由氢燃料电池驱动的无人驾驶飞机系统穿越大西洋的可行性。这架飞机必须完成 3000 公里的旅程，至少续航 36 小时。除了确保机载能源充足外，一个关键要求是整个推进系统在整个旅程中稳定运行。本文概述了为配备氢燃料电池推进系统的远程无人驾驶飞机系统设计的热管理系统的开发阶段、理论建模和实验测试。这架 4 米长、重量不到 25 千克的飞机计划从塞内加尔达喀尔飞往巴西纳塔尔，行程 3000 千米。开发这种氢动力无人机的一个关键挑战是设计一个高效的热管理系统，以确保机身持续通风。该系统的一侧涉及燃料电池发电以推动飞机，而另一侧则必须有效散发大量热量，以确保整个系统的稳定运行。

Thermal control of a hydrogen-powered uncrewed aerial vehicle for crossing the Atlantic Ocean

The Drone Mermoz project aims to evaluate the feasibility of an uncrewed aircraft system powered by a hydrogen fuel cell, designed to traverse the Atlantic Ocean. The aircraft must complete a journey of 3000 km with a minimum endurance of 36 hours. In addition to ensuring sufficient onboard energy, a critical requirement is the stable operation of the entire propulsion system throughout the journey.

This paper outlines the developmental stages, theoretical modeling, and experimental testing of a thermal management system designed for a long-range uncrewed aircraft system equipped with hydrogen fuel cell-based propulsion. The 4-meter, sub-25 kg aircraft is engineered to undertake a 3000 km journey from Dakar, Senegal to Natal, Brazil.

A critical challenge in developing this hydrogen-powered drone is designing an efficient thermal management system to ensure continuous ventilation of the fuselage. While one side of the system involves the fuel cell generating electricity for aircraft propulsion, the other side must effectively dissipate a substantial amount of heat to ensure the stable operation of the entire system.
