远程高空无人机系统（UAS）操作现在可以在全球重要的活火山现场测量火山气体化学。然而，在火山羽流中遇到的极端环境对机身开发和飞行控制都提出了重大挑战。作为2019年5月多学科现场部署的一部分，我们在巴布亚新几内亚的Manam火山上空飞行了固定翼UAS超视距（BVLOS），以测量火山羽流内的实时气体浓度。通过将航空气体测量与地面和卫星传感器相结合，我们的目标是收集数据，以限制对环境有重要意义的火山气体（如二氧化碳）的排放率，同时提供对地下火山系统状态的关键见解。在这里，我们提出了一个详细的分析三个超视距飞行到羽的Manam火山，并讨论了在高度动荡的火山羽中操作所面临的挑战。具体来说，我们报告了该系统的详细描述，包括地面和空中组件，以及飞行计划。我们目前记录的飞行数据，两个成功的飞行，以评估飞机的性能在羽流穿越过程中经历的大气条件下。此外，通过重建导致第三次飞行失败的事件顺序，我们确定了一些经验教训，并提出了适当的建议，以减少未来飞行操作的风险。
Long-range, high-altitude Unoccupied Aerial System (UAS) operations now enable in-situ measurements of volcanic gas chemistry at globally-significant active volcanoes. However, the extreme environments encountered within volcanic plumes present significant challenges for both air frame development and in-flight control. As part of a multi-disciplinary field deployment in May 2019, we flew fixed wing UAS Beyond Visual Line of Sight (BVLOS) over Manam volcano, Papua New Guinea, to measure real-time gas concentrations within the volcanic plume. By integrating aerial gas measurements with ground- and satellite-based sensors, our aim was to collect data that would constrain the emission rate of environmentally-important volcanic gases, such as carbon dioxide, whilst providing critical insight into the state of the subsurface volcanic system. Here, we present a detailed analysis of three BVLOS flights into the plume of Manam volcano and discuss the challenges involved in operating in highly turbulent volcanic plumes. Specifically, we report a detailed description of the system, including ground and air components, and flight plans. We present logged flight data for two successful flights to evaluate the aircraft performance under the atmospheric conditions experienced during plume traverses. Further, by reconstructing the sequence of events that led to the failure of the third flight, we identify a number of lessons learned and propose appropriate recommendations to reduce risk in future flight operations.
