DEVELOPMENT OF COOLING DEVICE IN ACCORDANCE WITH BUREAU OF SHIPS CONTRACT SPECIFICATION SHIPS-B-3575 DATED 11 JAN 1960
Abstract
The dual winding motor-blower combination was successfully completed, operated from a single capacitor and gave an improvement of approximately 20% in air delivery over the original design. A similar unit operated from either 60 or 400 cycles without switching windings and delivered approximately 25% more air. In addition to the motor design, new types of centrifugal wheels were developed which show an increase in air delivery of from 5 to 30% over those commercially available. Results are detailed. Life testing and environmental testing were in an advanced stage of completion with no unfavorable results (Life is 10,000 hours or 14 months). (Author)
