Exotic Propellers:

Precision machining of ducted thrusters; Rainbarrel project for Northrup Grumman. 

Whoops, we forgot to get a photo before we shipped a set of two of these thrusters, so we thought you would be interested in seeing a rendered image from the solid model we created in SDRC Ideas, our CAD modeler. These thrusters were machined from 20 by 20 by 4 inches thick 6061-T6 plate aluminum, hand finished, precision balanced, and hard anodized.
