SLD capabilities of icing wind tunnels

2015-07-09

WIP

AIR6341

The purpose of this AIR is to compile in one definitive source, commonly accepted calibration, acceptance criteria and procedures for simulation of Supercooled Large Droplet (SLD) conditions within icing wind tunnels. Facilities that meet the criteria for either some or all of the recognized conditions will have known SLD icing simulation capability.

AIR6247

This document is intended to serve two purposes: (1) provide a list of topics for potential customers to ask of the facility to aid their selection decision-making, and (2) provide a list of icing wind tunnel and engine test stand facilities that simulate flight through icing or ice crystal clouds.

Ice Crystal and Mixed Phase Icing Tunnel Testing of Air Data Probes

2018-04-16

WIP

AIR6974

This document provides information on current practices for testing air data probes to 14 CFR Part 33 Appendix D ice crystal and mixed phase icing conditions. This AIR is primarily concerned with techniques for measuring the flow and icing environment in the test facility. While the focus of this report is the testing of air data probes, techniques described may be applicable to Appendix D tests of other aerospace equipment as well.

Ice and Rain Minimum Performance Standard for Angle of Attack (AOA) and Angle of Sideslip (AOS) Sensors

2020-08-26

WIP

AS6838

The new standard will establish minimum performance requirements for angle of attack (AOA) and angle of sideslip (AOS) sensors in ice and rain conditions. The new standard will cover the various sensor technologies used to measure these flow angles and is limited to the sensor itself as defined from the portion of the sensor that is directly exposed to the ice and rain environment to the means by which its output is relayed to the relevant aircraft systems. The user of this standard must evaluate the aircraft level installation requirements for the probe to ensure adequate coverage for the application. It may be necessary to modify the test conditions in order to meet the applicable installation requirements.

Droplet Sizing Instrumentation Used in Icing Facilities

2013-04-23

CURRENT

AIR4906

A review of droplet sizing instruments used for icing research is presented. These instruments include the Forward Scattering Spectrometer Probe, the Optical Array Probe, the Phase Doppler Particle Analyzer, the Malvern Particle Size Analyzer, the oil slide technique, and the rotating multicylinder. The report focuses on the theory of operation of these instruments and practical considerations when using them in icing facilities.

Icing Wind Tunnel Interfacility Comparison Tests

HISTORICAL

AIR5666

This SAE Aerospace Information Report (AIR) presents and discusses the results of tests of three models in six icing wind tunnels in North America and Europe. This testing activity was initiated by the Facility Standardization Panel of the SAE AC-9C Aircraft Icing Technology Subcommittee. The objective of the testing activity was to establish a benchmark that compared ice shapes produced by icing wind tunnels available for use by the aviation industry and to use that benchmark as a basis for dialogue between facility owners to improve the state-of-the-art of icing wind tunnel technology.

CURRENT

ARP5904

This SAE Aerospace Recommended Practice (ARP) document establishes criteria and recommended practices for the use of airborne icing tankers to aid in design and certification of aircraft ice protection systems and components. Several icing tankers are described, along with their capabilities and suggested use. Sample data for these tanker spray systems are included, shown with 14 CFR Parts 25 and 29, Appendix C icing envelopes for continuous maximum and intermittent maximum icing conditions. (Note: In the remainder of this document, the phrase “Appendix C icing envelopes” will be used for brevity.) This ARP is intended as a guide toward standard practice and is subject to change to keep pace with experience and technical advances.

Summary of Icing Simulation Test Facilities

HISTORICAL

AIR5320

This SAE Aerospace Information Report (AIR) contains information on most of the major icing simulation ground facilities. An effort was made to obtain data from as many facilities as possible over a two year time period. The data in this document represents the state of the facilities in calendar year 1996. Facilities are constantly changing and upgrading and, therefore, some facility specifications may change during the life of this report. Of the 27 facilities described in this report, the primary use is split with approximately half for engine testing and half for wind tunnel testing. The facilities are limited to ground facilities and, therefore, icing tankers have not been included.
