Icing Tests with 3D Wing Mockup rescheduled

On November 22, 2021 the Austrian Government announced a nation wide lockdown due to increasing COVID cases. For this reason, the for December planned icing tests with the 3D wing mockup have been rescheduled for January 2022. The JOICE consortium is looking forward to the tests!

Aircraft Icing Talk by SNU

On November 25, 2021 a talk by Prof. Yee Kwanjung from the Seoul National University (SNU) about the phenomena of aircraft icing was held in front of an international audience. The activities of SNU and its Aerospace Vehicle Design Laboratory (AVDL) were presented. SNU is a project partner in JOICE and contributes to the development and implementation of numerical methods. The AVDL has been investigating various research subjects in the field of numerical simulation, such as aircraft/high-speed train icing, helicopter aerodynamics, and multi-discipline design optimization.

Icing Tests with 2D Wing Mockup

The first icing tests with the 2D wing mockup were conducted in the large icing wind tunnel at Rail Tec Arsenal in Vienna in September 2021. The test conditions were derived from Appendix C and Appendix O icing conditions according to Certification Specifications for Large Aeroplanes (CS-25) by EASA. Icing was performed at velocities up to 80 m/s and temperatures as low as -20°C. The experimental investigation was a great success. Validation data for different icing conditions without heating (unprotected) and with heating (anti-ice system) for the tested specimen were generated. The ice accretion was also documented by means of 3D laser scanning.

Manufacturing of Wing Mockups

The 2D and 3D wing mockup are being manufactured for the icing tests at Rail Tec Arsenal and will be finished according to schedule. Both mockups have integrated instrumentation for the measurement of pressure and temperature on various pre-defined positions on the wing. Furthermore, a heating system is embedded in the leading edge of each wing mockup, which is divided into separate zones. Each zone can be controlled and activated individually. As a result, many different test setups can be tested with the mockups.

Small-Scale Experimental Testing

One of the main goals of JOICE is the improvement of simulation tools for icing and the generation of validation data. Therefore, a series of icing tests was performed at the icing wind tunnel of FH JOANNEUM with a small scale NACA 23012 airfoil section. The airfoil section was exposed to different icing conditions during the experimental tests, which resulted in glaze and rime ice accretion. The final ice accretion was documented by means of 3D laser scanning and with photographs. The experimental results were compared to results obtained with simulations of various icing codes

Evening Lecture

At the Institute of Aviation of the FH JOANNEUM University of Applied Sciences in Graz an evening lecture was held on 8th of June 2021. After a general introduction to the phenomena of in-flight icing, project JOICE was presented, following an interesting discussion and exchange of experiences with in-flight icing. About 50 persons attended the evening lecture.

SAE AC-9C Aircraft Icing Technology Committee Meeting

From 19 to 23 of April 2021 the SAE AC-9C Aircraft Icing Technology Committee meeting was held. SAE is a worldwide active association and standards developing organization for engineering professionals  in various industries. The AC-9C Committee is focusing on developing standards and recommended practices in the area of aircraft icing. As part of the meeting, project JOICE was presented to the committee of international experts.

Wing Mockup Geometry selected

As part of JOICE a 2D wing mockup and a 3D wing mockup will be manufactured and tested in the RTA icing wind tunnel under relevant conditions. The mockups will be used to generate validation data for the numerical methods developed within the project and included in the validation database. For the 2D wing mockup a NACA 23012 geometry was selected. The 3D wing mockup will be a 65% scaled wingtip section of the NASA common research model.
