瞬变热像技术是一种在复合材料和航天结构评估中获得成功应用的方法。它具有提供有关复合结构中隐藏缺陷或特征的定性和定量结果的能力。飞机必须接受例行维护检查,以检查是否有严重损坏,从而确保其安全。这项工作旨在解决无损检测自动化检测的挑战,并通过提出一种使用无人机(无人机)主动热像系统的自主热像成像方法来提高缺陷检测能力。讨论了主动热像仪的概念,并将其应用于飞机碳纤维板的检测,提出了利用无人机进行实时检测的航空检测任务规划。结果表明,该方法可以显著减少检测时间、成本和工作量,同时潜在地增加了飞机复合材料缺陷的检测概率。
Transient thermography is a method used successfully in the evaluation of composite materials and aerospace structures. It has the capacity to deliver both qualitative and quantitative results about hidden defects or features in a composite structure. Aircraft must undergo routine maintenance – inspection to check for any critical damage and thus to ensure its safety. This work aims to address the challenge of NDT automated inspection and improve the defects’ detection by suggesting an autonomous thermographic imaging approach using a UAV (Unmanned Aerial Vehicle) active thermographic system. The concept of active thermography is discussed and presented in the inspection of aircraft CFRP panels along with the mission planning for aerial inspection using the UAV for real time inspection. Results indicate that the suggested approach could significantly reduce the inspection time, cost, and workload, whilst potentially increase the probability of detection of defects on aircraft composites.
