Abstract : It was found that passive deicing methods do not operate with sufficient reliability to be used in operational situations and that in general, successful use of passive deicers is usually linked to a particular geometry, icing condition or waste energy availability that do not commonly exist at the radome sites of interest. Mechanical deicing was evaluated and test mechanical deicers were constructed and subjected to testing in cold rooms and field-tests at Mt. Washington, N.H. It was found that an inflatable deicing system coupled with a commercially available ice detector could be configured as an automatic deicing system. This system showed success under light and heavy icing conditions and during long periods of icing activity. (Modified author abstract)
