This paper describes the design of a miniature air suction system to house a chemical sensor. It has been designed to improve the aerodynamic chemical sensing efficiency and to have a low weight since it is meant to be mounted on a micro air vehicle. The design is done around a readily available miniature axial flow fan by computational methods. A converging-diverging shape for the air suction system with the sensor disc having a central hole and mounted at the throat is proposed as good design concept. The systematic approach has led to a light weight system with high aerodynamic efficiency even under extreme flow conditions that may be caused by MAV manoeuvre or cross winds.

本文介绍了用于容纳化学传感器的微型吸气系统的设计。它被设计为提高空气动力学化学感测效率并具有轻巧的重量，因为它打算安装在微型飞行器上。通过计算方法围绕一个现成的微型轴流风扇进行设计。作为具有良好的设计思想，提出了具有带有中心孔并安装在喉部的传感器盘的吸气系统的会聚-扩散形状。这种系统化的方法即使在由MAV操纵或侧风可能导致的极端流动条件下，也可以实现具有高空气动力学效率的轻量化系统。
