本SAE航空航天标准（AS）规定了用于除冰和/或防冰飞机的AMS1424 I型和AMS1428 II、III和IV型流体的空气动力流量要求和试验程序。本标准的目的是确保除冰/防冰液在起飞地面加速和爬升期间从飞机升降面和操纵面流出时具有可接受的空气动力学特性。飞机地面除冰/防冰液的气动验收基于平板上的流体边界层位移厚度（BLDT），在经历代表性飞机起飞的自由流速度时程后测量。 通过将候选流体的BLDT测量值与参考流体BLDT值和干燥（清洁）试验板上的BLDT值建立的基准值进行比较，确定流体的可接受性。在航空服务中使用未稀释液体的温度范围内进行测试。

This SAE Aerospace Standard (AS) establishes the aerodynamic flow-off requirements and test procedures for AMS1424 Type I and AMS1428 Type II, III, and IV fluids used to deice and/or anti-ice aircraft.The objective of this standard is to ensure acceptable aerodynamic characteristics of the deicing/anti-icing fluids as they flow off of aircraft lifting and control surfaces during the takeoff ground acceleration and climb. Aerodynamic acceptance of an aircraft ground deicing/anti-icing fluid is based upon the fluid¿¿¿s boundary layer displacement thickness (BLDT) on a flat plate, measured after experiencing the free stream velocity time history of a representative aircraft takeoff. Acceptability of the fluid is determined by comparing BLDT measurements of the candidate fluid with a datum established from the values of a reference fluid BLDT and the BLDT over the dry (clean) test plate. Testing is carried out in the temperature range at which the fluid, undiluted and diluted, is to be used in airline service.
