The Flakt Woods Group, a well-known manufacturer of large industrial fans, had to deliver to a major defense organization fans to be used in many different applications with very stringent and widely varying technical specifications and requirements. In order to meet the delivery schedule, they outsourced the design of one of the more challenging fans to PCA Engineers, engineering consultants specializing in turbomachinery design.
The critical requirement was that the fan should have nearly flat operating characteristics, so that delivery pressure does not rise significantly as the volume flow falls. Normally, we would have begun by looking for a similar design that we had done in the past, but we had never produced anything similar to this one.
