| 摘 要： | 嵌入式大气数据传感(FADS)系统较之传统的大气数据系统有很大的优势,它依靠飞行器前端的压力传感器间接得到飞行大气数据.在本文中,首先简要介绍了FADS系统的压力模型;然后通过分析压力传感器几何外形设计对系统性能的影响,建立了压力传感器的动力学模型,并提出了FADS系统中的压力传感器的设计准则;最后给出了仿真结果.

| Abstract: | The flush airdata sensing system is much better than the traditional airdata system,and it depends on the pressure sensors allocated on the forebody of aircraft to derive the airdata indirectly.In this paper,at first the pressure model is showed briefly.And then an analysis is given,which is about the effect of the internal sensors geometry appearence on system performance;and the aerodynamic model of the pressure sensors has been developed,furthermore,the design criteria for the pressure sensors of FADS system has been formulated.Finally,the result of the simulation has been showed. |
