Civilian Aircraft Turboprop Engine Inlet

Mr. Andrew J. Crook of the Allison Engine Company used Gridgen to create this grid for a civilian aircraft turboprop engine inlet. Air flow enters through the yellow/purple region on the lower left and exits mostly to the upper right. The foreign object collection duct is on the lower right. The shaft joining the engine to the propeller goes through the red hole in the upper portion of the illustration.
