Abstract

The oil pipeline network requires periodic monitoring to detect pipeline damages, which may cause oil leakage with severe environmental contamination. These damages can be generated by interference from third parties such as construction works, sabotage, vandalism, excavations,and illegal oil theft. Todetect the oil pipeline damages,it canbeusedaerodynamic aerial vehicles (UAVs) with infrared cameras and image processing systems. This paperpresents the aerodynamic analysis of a UAV with a hawk shape (wingspan of 2.20 m and length of 1.49 m) for potential application in the detection of oil pipeline failures. A 1:6.5 scale prototype of the UAV is fabricated using a 3D printer. The aerodynamic coefficients of UAV are determined using computational fluiddynamic (CFD) simulations and experimental testing with a subsonic wind tunnel. In addition, the lift and drag coefficients of UAVsare obtained as a function of Reynolds number and angle of attack. Also, the air velocity profile around UAV is estimated with the CFD model. The proposed UAV could decrease the inspection costs of pipeline networks in comparison with the use of helicopters or light aircraft.

用于油气泄漏监测的鹰形无人机的空气动力学分析
石油管网需要定期监测,以发现管道损坏,这些损坏可能造成漏油,并对环境造成严重污染。这些损害可能是由第三方的干扰造成的,如建筑工程、破坏、故意破坏、挖掘和非法盗窃石油。为了检测输油管道的损坏,可以使用带有红外摄像机和图像处理系统的气动飞行器(uav)。本文介绍了一种鹰形无人机(翼展2.20 m,长1.49 m)在石油管道故障检测中的应用前景。1:6.5比例的无人机原型是用3D打印机制造的。采用计算流体力学(CFD)模拟和亚音速风洞试验方法确定了无人机的气动系数。此外,还得到了无人机升力系数和阻力系数随雷诺数和迎角的变化规律。同时,利用CFD模型估计了无人机周围的空气速度分布。与使用直升机或轻型飞机相比,拟议的无人机可以减少管道网络的检查成本。
