- Mark-15 External Dimensions -
AND a 3D-CAD File of the M-15 Gearbox Assembly
The following pictures show the major exterior dimensions of the Mark-15 gearbox.
In order to provide a perspective of the Mark-15 with respect to cowl lofting, the following 3 pictures show side views of the Mark-15 gearbox with 20, 18, and 14-inch diameter spinners each with the rear face located in-plane with the prop-flange face, which is approximately where an actual spinner bulkhead will be located.
Note that in order to provide even more cowling flexibility, the Mark-15 gearbox is available with one, two and three-inch longer propshafts than shown here.
We have recently made available a 3D-solid-model file of the Mark-15 to help potential customers with design and lofting efforts. Use THIS LINK to download the Mark-15 3D-model.
In order to view this 3D file, you will need to download the free eViewer program from the SOLIDWORKS website.
