5、 and Processes for Evaluation of Aerodynamic Effectsof SAE-Qualified Aircraft Ground Deicing/Anti-icing FluidsRATIONALEThe document has been revised to include a caution note about Non-Glycol fluids. SAE publications AMS1424/1 and AMS1424/2 were also included in the list of references.FOREWORDThe qu

6、alification processes for SAE fluids is described in ARP5718, and the standards, including aerodynamic standards, with which the fluids must comply are given in AMS1424 (Type I) and AMS1428 (Types II, III, and IV). These standards require that the aerodynamic performance of all fluids be tested and

7、qualified in accordance with AS5900, the Aerodynamic Acceptance Test (“AAT”). The purpose of the AAT is to ensure that new fluids have aerodynamic performance properties that are not worse than an established, accepted standard. In this way, the AAT provides a general screening of the aerodynamic ef

8、fects of the fluids. Even with successful AAT qualification, however, there can be circumstances which require evaluation of the aerodynamic effect of the fluids on specific aircraft.The intent of this ARP is to provide guidance for the evaluation of aerodynamic effects of fluids on aircraft, if it

9、is determined that an evaluation is required to ensure safe operation of an aircraft with fluids applied. The ARP describes previously used methods and methods under development. To evaluate fluid effects on a particular model, it should typically not be necessary to utilize more than one method des

10、cribed in this ARP; however, depending upon the circumstances, it may be advantageous to do so (e.g., similarity analysis combined with CFD).The recommended practices and other information described herein are limited to the experiences of the members of the SAE G-12 ADF Aerodynamics Working Group.

11、Thus, this ARP is not intended to be an exhaustive discussion of information from all possible sources. Should users of this ARP, or other entities with relevant experience, have additional recommendations or revision suggestions, they are encouraged to contact the SAE G-12 ADF Aerodynamics Working

DEICING/ANTI-ICING FLUIDS AND THEIR EFFECT ON AERODYNAMICS3.1 Deicing/Anti-Icing Fluid TypesThe SAE standards categorize fluids as Type I, II, III, or IV. The fluids are qualified to one of two S

46、AE standards, dependingupon their physical performance. Type I fluids are qualified to AMS1424 and are Newtonian fluids. Historically, Type I fluids have essentially been mixtures of glycol, water, surfactants, and corrosion inhibitors. More recently, Type Is utilizing freezing-point depressants oth

47、er than glycol have been introduced. Type I fluids provide very limited holdover time (HOT).Types II, III, and IV fluids are qualified to AMS1428 and are non-Newtonian, pseudo-plastic fluids. This means that as the shear stress on them increases, their viscosity decreases so that they flow off as th

48、e airplane speed increases during takeoff ground roll. These fluid types contain thickening polymers which facilitate the fluid maintaining greater thickness on the airplane surfaces following application, thereby providing longer HOTs than Type I fluids. Type II fluids were developed to satisfy the

49、 desire for longer HOTs than are provided by Type Is. Type IV fluids were developed after Type IIs to further lengthen HOTs. Most recently developed were Type III fluids, which provide longer HOTs than Type Is while maintaining acceptable aerodynamic effects for commuter-type aircraft with low takeoff rotation speeds, although they may be permitted on other types as well.3.2 Aerodynamic ImpactsThe application of fluids rem
