Abstract

Turbulence detection and mitigation represent significant challenges in aviation, particularly for Advanced Air Mobility (AAM) systems encountering thermal and mechanicalturbulence at low altitudes. Early detection of such flow disturbances is crucial, as it allows for timely evasive manoeuvres or countermeasures to ensure safe operations. While Doppler light detection and ranging (lidar) sensing has been developed for large passenger aircraft, their size, weight, and power requirements has so far limited their utility in AAM vehicles. This paper reviews advancements in airborne Doppler lidar technology and evaluates the trade-offs which promise to enable the miniaturisation of these sensors. A case study is performed to examine the effects of sensor mass and power consumption on the range of three air taxi configurations. Advancements in optical technology are expected to facilitate the integration of efficient, compact lidar sensors into smaller AAM vehicles, enhancing their ability to detect and respond to turbulence, thereby improving their safety.

机载多普勒激光雷达风感研究进展

湍流探测和缓解是航空领域面临的重大挑战，特别是在低空遇到热湍流和机械湍流的先进空中机动（AAM）系统。早期发现这种流动干扰是至关重要的，因为它允许及时规避操作或对策，以确保安全操作。虽然多普勒光探测和测距（激光雷达）传感已经开发用于大型客机，但它们的尺寸、重量和功率要求迄今为止限制了它们在AAM车辆中的应用。本文回顾了机载多普勒激光雷达技术的进展，并评估了有望实现这些传感器小型化的权衡。通过一个案例研究来检验传感器质量和功耗对三种空中出租车配置范围的影响。光学技术的进步有望促进将高效、紧凑的激光雷达传感器集成到较小的空对空车辆中，增强其探测和响应湍流的能力，从而提高其安全性。
