Development of the Ambassador De‐icing System: An Account of a Series of Experiments Leading to a Satisfactory Installation

WHEN the original design of the Ambassador's thermal de‐icing was conceived very little practical experience had been gained on such systems in this country, and almost no theoretical data were available. Little or no development had been carried out on the numerous new components involved, so much credit must be given to the initial project work of the Airspeed design team (in particular Mr W. T. Blanchard), and of Radiation Limited (design of the combustion heaters), which resulted in no fundamental changes having to be made during the Ambassador development trials, although a considerable number of refinements were necessary.
