| Abstract: | The Supercooled Large Droplet(SLD)icing is a new problem that emerged in recent years.The ice detection technology of SLD,which restricts the overall development of the air-craft icing protection system,is a key technology for securing the aircraft flight safety.The arti-cles published recently on SLD ice detection are summarized and discussed.The new problems of the ice detection technology when applyied to SLD are presented from the perspectives of the icing mechanism and the detection principle.The new requirements of the SLD icing detection technol-ogy are summarized through the analysis of the latest airworthiness specification.According to the technology maturity,the SLD icing detection technologies are introduced in detail.A new classification method for the probe type SLD icing detector is firstly reported including droplet traj ectory detection and back-flow characteristics detection. |
