Figure 8 - Details of Model OV-2 



The primary purpose of Model OV-2 was to determine whether an 

 increase in interbay strength exists over that of the original design and 

 to verify the elastic behavior predicted by the analysis of Reference 3. 

 It was felt that these objectives could be accomplished by fabricating a 

 model from steel plating of only about one diameter in length. Thus, 

 Model OV-2 affords a direct strength comparison with Model OV-1 . 



The dimensions and design details of Model OV-2 are shown in 

 Figure 8. Fabrication procedures for this model were identical to those 

 for Model OV-1. The inner shell had an average thickness of 0.296 in.
