My company performs shot peening on hundreds of different parts for Sikorsky. The standard practice is to find the smallest material thickness then go to Table II of SS8766. In your case the minimum intensity would be .008A. However your maximum intensity may or may not be .012A. As stated in SS8766 section 3.2.3 the maximum intensity shall be below the threshold of erosion of the basis material and shall not cause undue warpage on the part.
If you'd like, e-mail me the part number you are trying to peen if we have a Sikorsky Approved technique I will share with you the intensity values we have established.
