SYSTEM DESCRIPTION 



This study resulted in a conceptual design essentially 

 satisfying the requirements detailed in the preceding section. 

 The design, shown diagrammatically in Figure 13, consists of 

 a niimber of lengths of three-quarter-inch diameter cable 

 coupled end-to-end with a pipe-like housing. This housing 

 (Figure 10) provides for instrumentation in the central section. 

 The end pieces contain the cable terminals and appropriate 

 electrical fittings. 



The cable is covered with a free-swiveling, hydrodynamic 

 fairing (Figure 9) to reduce drag and vibration. The instru- 

 ment modules are also faired. 



A core-space of about one-half- inch diameter is available 

 within the load -carrying cable armor to accommodate any suit- 

 able electrical cable. 



The cable-fairing-module assembly is retained at proper 

 depth by a depressor (Figure 3) which develops the requisite 

 depressing force by a combination of weight and hydrodynamic 

 reaction. 



Shipboard handling can be accomplished by a tractor- 

 type capstan (Figure 12) for systems with rigid instrument 

 modules distributed along the faired cable, or a twin load- 

 drum (Figure 11) for systems lacking modules.
