Design Approach 



Most of the requirements are £,atisfied by a previously 

 developed fairing, the DTMB TF-84; to miniiaize developmental 

 costs, it was decided to adapt that fairing to the present 

 application. Itein. 3, 6, 1, and 8 of the preceding list of 

 requirements constituted the only problem areas in this adap- 

 tion. Solutions to these probleiQs are discussed below: 



1. Resistance against permanent set or damage vAien 

 stored in multiple layers 



Damage due to storage in multiple layers was 

 avoided by storing under lightly loaded conditions. 



2. Low cost in fabrication 



Cost of fabrication could be reduced by the use 



of a single-rubber compound in the fairing in 



place of the two-compound construction usually 



used? the results of an investigation of this 

 possibility are discussed later. 



3. Simplicity in assembly of the fairing to the cable 

 Since the expense of assembling the fairing to the 

 cable is primcirily due to the labor involved, the 

 clips and hangers used for t2iis purpose were designed
