Research Institution
Ice accretions on helicopter rotor blades occur as a result of the impact of supercooled water particles on the surface. Supercooled water particles are in an unstable state. Means are sought to "trip" these particles into ice crystals or amorphous snow so that the particles will not adhere to the surface. Density waves (sound) and electromagnetic waves (including lasers) are to be investigated for suitability as "trip" mechanisms reduce the icing potential. Experiments will be conducted in a microcalorimeter using super cooled water in capillary tubes. The kinetics of freezing will be studied for the various "trip" mechanisms.
