Flight Tests to Investigate Supercooled Large Droplets in Icing Conditions

摘要

NLR investigated the icing atmosphere for aircraft by flying with an instrumented research aircraft through clouds. Liquid water content, droplet diameter distributions and air temperature were measured. Large droplets were found in air masses with a limited extent. The flight campaign and the results from the campaign are presented. Measurements are compared with limits in regulations for aircraft and helicopter operation in icing conditions. The investigation was made in the framework of a European co-operation in the EURICE project, partially funded by the Directorate General VII for Transport of the European Commission.
