Abstract
Tests were done in artificial icing conditions to determine what effects ice, accreted during ground running, had on the subsequent performance and handling characteristics of a helicopter. The results indicated that the helicopter used, a Bell 47G, was limited by the profile drag caused by ice on the main rotor blades, to the extent that, after only a few minutes exposure to icing at temperatures below about -10°C., flight was not possible.
