Methods and Processes for Evaluation of Aerodynamic Effects of -Qualified Aircraft Ground Deicing/Anti-icing Fluids
 N ARP6852B

Annotation

This document describes methods that are known to have been used by aircraft manufacturers to evaluate aircraft aerodynamic performance and handling effects following application of aircraft ground deicing/anti-icing fluids (“fluids”), as well as methods under development. Guidance and insight based upon those experiences are provided, including

Similarity analyses

Icing wind tunnel tests

Flight tests

Computational fluid dynamics and other numerical analyses

This document also describes

The history of evaluation of the aerodynamic effects of fluids

The effects of fluids on aircraft aerodynamics

The testing for aerodynamic acceptability of fluids for SAE and regulatory qualification performed in accordance with AS5900

Additionally, Appendices A to E present individual aircraft manufacturers’ histories and methodologies which substantially contributed to the improvement of knowledge and processes for the evaluation of fluid aerodynamic effects

NOTE: This document is applicable for fluids that are “qualified” to (i.e., have passed) the tests and other standards prescribed in AMS1424 or AMS1428 and are properly used in accordance with ARP4737

NOTE: There are topics of potential interest not discussed in this document, such as re-hydrated gel residues (see 2.2)
