皮托管皮托管Pitottube测量气流总压和静压以确定气流速度的一种管状装置。由法国H.皮托发明而得名。严格地说，皮托管仅测量气流总压，又名总压管；同时测量总压、静压的才称风速管，但习惯上多把风速管称作皮托管。皮托管的构造如图，头部为半球形，后为一双层套管。测速时头部对准来流，头部中心处小孔（总压孔）感受来流总压p0，经内管传送至压力计。头部后约3～8D处的外套管壁上均匀地开有一排孔（静压孔），感受来流静压p，经外套管也传至压力计。对于不可压缩流动，根据伯努利方程，风速为，式中ρ为气流密度。对于可压缩流动，测定p0和p以后，根据能量方程可求出气流马赫数，进而再求速度。但在超声速流动中，皮托管头部出现离体激波，总压孔感受的是波后总压，来流静压也难以测准，因而皮托管不再适用。总压孔有一定面积，它所感受的是驻点附近的平均压强，略低于总压，静压孔感受的静压也有一定误差，其他如制造、安装也会有误差，故测算流速时应加一个修正系数ζ，即。ζ值一般在0.98～1.05范围内，在已知速度之气流中校正或经标准皮托管校正而确定。皮托管结构简单，使用方便，用途很广。如飞机头部或机翼前缘常装设皮托管，测量相对空气的飞行速度，又称空速管。皮托管构造图
