HANGER 



Requirements 



A hanger 5 mounted at the top of each 200-foot length of 

 fairing ff ia required to transmit the hydrodynamic drag on the 

 fairing to the cable stop. This hanger must grip the fairing 

 firmly so as to sustain the maximum load without damage to 

 the fairing. For design purposes, the maximvim load was taken 

 to be 510 pounds, the same as that required of the stop. 



Design Approach 



It was decided that the terminal clip must attach to the 

 load-carrying member of the fairing (which is the Dacron cord- 

 ing) in order to prevent tear-out or rupture of the fairing. 

 A design was conceived (Figure 5) in which this was accom- 

 plished by means of bending a small length of the Dacron cord- 

 ing^ from which the faired section had been removed, and 

 gripping this cording in a clamp. Additional clamping effort 

 was achieved by side plates which cleunped a length of fair- 

 ing approximately six inches long. The developmental clamp 

 is shown, attached to a short length of the fairing, in 

 Figure 1-7. 



Under test, this device sustained a load of 900 pounds. 



During assembly of the cable and fairing used for the 

 sea trials, all tenninal clips and stops were subjected to 

 a 300-pound proof load.
