Abstract

Pressure distribution measurement over the surface of an aircraft can contribute to drag reduction on the flight, increasing aerodynamic efficiency and decreasing fuel consumption. Current methods for pressure distribution measurement include the use of Pressure Sensitive Paints (PSPs), which can only be used during the design phase, and Fiber Bragg Grating (FBG), which is not easy to install on existing aircraft. Drag reduction can be achieved by active flow control by using pressure taps for pressure distribution as shown in the literature. In this paper, we present investigations on the realization of an autonomous wireless pressure sensor that can be attached to the outer skin of aircraft, thus offering minimal installation effort. In order to analyze the feasibility with respect to sensing capabilities and wireless communication, tests were carried out on an HQ17 wing profile segment. Pressure measurements were compared with a reference pressure obtained from Global Positioning System (GPS) data in order to estimate airspeed through differential pressure measurement.

飞机无线压差测量

飞机表面的压力分布测量有助于减少飞行阻力，提高气动效率和降低燃油消耗。目前用于压力分布测量的方法包括使用压力敏感涂料(psp)，这只能在设计阶段使用，以及光纤布拉格光栅(FBG)，这在现有飞机上不易安装。如文献所示，通过使用压力龙头进行压力分配，可以通过主动流量控制来实现减阻。在本文中，我们提出了一种自主无线压力传感器的实现研究，该传感器可以附着在飞机的外壳上，从而提供最小的安装工作量。为了分析在传感能力和无线通信方面的可行性，在HQ17机翼剖面段上进行了测试。将压力测量值与全球定位系统(GPS)数据获得的参考压力进行比较，以便通过差压测量来估计空速。
