空速管是飞机上极其重要的机载装置之一。通过空速管得到的数据,不仅为飞行员提供飞机的空速信息,同时通过空速管测得的静压生成升降速度表,提供飞行员飞机的爬升率信息。该文将采用风洞试验手段研究国内某型客机上使用的空速管,得到空速管的空速输出特性,同时研究防冰加热系统对空速输出的影响。 Airspeed tubes are one of the most important onboard devices on the plane. The data obtained from the HTS not only provides the pilot with the airspeed information of the aircraft, but also generates the ascending and descending velocity table by the static pressure measured by the HTS and provides the pilot’s climb rate information. In this paper, we will use wind tunnel test to study the airspeed pipe used in a domestic passenger aircraft and obtain the airspeed output characteristics of the airspeed pipe. At the same time, the influence of anti-ice heating system on airspeed output will be studied.
