Abstract

Anti-icing and de-icing test techniquesdealing withthe particle size change on the cloud propagation path, the matching between icing cloud and the helicopter flow field, and the calibration of cloud parameters are mainly studied. The work carried out the first anti-icing and de-icing test under the hovering state of helicopters in China, designed corresponding test safety measures, and completed the acquisition of relevant parameters and icing types. A series of test results show that the icing spray tower has the ability to simulate icing cloud under continuous icing conditions in CCAR-29 Appendix C when the helicopter is on the ground and in hover.

Key words

helicopter / ice spray tower / icing characteristics test / de-ice/anti-ice system / continuous maximum icing / calibration of cloud generation
