This SAE Aerospace Recommended Practice (ARP) document provides recommended practices for the calibration and acceptance of icing wind tunnels to be used in testing of aircraft components and systems and for the development of simulated ice shapes. This document is not applicable to air-breathing propulsion test facilities configured for the purposes of engine icing tests. Use of facilities as part of an aircraft's ice protection Certification Plan should be reviewed and accepted by the applicable regulatory agency prior to testing. Following acceptance of a test plan, data generated in these facilities may be submitted to regulatory agencies for use in the certification of aircraft ice protection systems and components. Certain types of tests may be appropriate in facilities with capabilities that are not as rigorously characterized as by the practices defined herein, and the acceptability of these tests should be coordinated with the applicable regulatory agency.

The icing research tunnel at the NASA Glenn Research Center underwent a major rehabilitation in 1999, necessitating recalibration of the icing clouds. This report describes the methods used in the recalibration, including the procedure used to establish a uniform icing cloud and the use of a standard icing blade technique for measurement of liquid water content. The instruments and methods used to perform the droplet size calibration are also described. The liquid water content/droplet size operating envelopes of the icing tunnel are shown for a range of airspeeds and compared to the FAA icing certification criteria. The capabilities of the IRT to produce large droplet icing clouds is also detailed.

The effects of inflight atmospheric icing can be devastating to aircraft. Universities and industry have been hard at work to respond to the challenge of maintaining flight safety in all weather conditions. Proposed changes in the regulations for operation in icing conditions are sure to keep this type of research and development at its highest level. This is especially true for the effects of ice crystals in the atmosphere, and for the threat associated with supercooled large drop (SLD) icing. This collection of ten SAE International technical papers brings together vital contributions to the subject. Icing on aircraft surfaces would not be a problem if a material were discovered that prevented the freezing and accretion of supercooled drops. Many options that appeared to have promising icephobic properties have had serious shortfalls in durability. This title addresses, among other topics, the measurement techniques and the drop physics that apply to icing, certification for flight through ice crystal clouds and in supercooled large drops, improvements in predictive techniques, scaling methods, test facilities and techniques, and rotorcraft icing.

"The purposes of this document are (1) to provide an overview of the calibration of subsonic and transonic wind tunnels and (2) to provide a basis for commonality within the wind tunnel community in the area of wind tunnel calibration. Various standards have been developed over the years in the aeronautics industry, many of which pertain to ground testing. These standards have made it easier to share information and hardware, and have allowed the community to improve its overall effectiveness. This document, however, is not intended to set standards for wind tunnel calibration. Details of calibrating a wind tunnel vary from facility to facility according to the type of tests conducted, the operating envelope of the tunnel, and the physical constraints of the facility, which makes having a rigid definition of calibration procedures inappropriate. Instead, this document provides a set of recommended practices that the reader can use to develop a complete tunnel calibration program."--Executive summary, p. 1.
