From a safety viewpoint, the cable may be 

 either friend or foe. In the event of the 

 vehicle fouling or the loss of surfacing abil- 

 ity, the cable can be used as a retrieval line. 

 Conversely, if the cable fouls, provisions are 

 made in KUROSHIO II for the occupants to 

 release the cable directly from the hull. 



DIESEL-ELECTRIC 



To reduce the dependency on surface sup- 

 port, several submersibles incorporate diesel 

 engines in their power inventory for surface 

 propulsion (Table 7.1) and, in a few, to re- 

 charge depleted batteries after a dive. In 

 essence, they follow procedures quite similar 

 to those of conventional battery-powered 

 military submarines. The French submers- 

 ible ARGYRONETE, had it been completed, 

 would have operated identically to a military 

 submarine in that its diesel motors would 

 have provided full autonomy for surface 

 cruising and battery charging, while lead- 

 acid batteries would have supplied sub- 

 merged power. 



The submersibles now in existence use 

 their diesel-electric motors not so much for 

 long-range surface transits as for charging 

 batteries or powering an air compressor to 

 refill depleted air tanks. The following de- 

 scriptions relate the surface power and de- 

 tails available for the vehicles SUBMANAUT 



and TOURS 66. In GOLDFISH a Ford V-8 

 engine supplies power for direct drive on the 

 surface and is coupled to a 6.4-kW generator 

 (200 amp at 32 V) for battery charging and 

 for compressor operation in recharging of air 

 tanks. 



SUBMANAUT: 



Martine's SUBMANAUT realizes surface 

 propulsion from a fresh water coiled. General 

 Motors 6-cylinder diesel engine (Model 6-71) 

 which develops approximately 235 hp. Sur- 

 face cruising speed is 10 knots and the on- 

 board diesel fuel (300 gal) allows a range of 

 2,000 nautical miles. A 5-kW generator is 

 belted to the forward end of the diesel engine 

 and is used to recharge the vehicle's batter- 

 ies. Approximately 2 hours of charging time 

 are required to balance 1 hour of discharge 

 time (45 amp at 150 V). A 3,000 psi air com- 

 pressor is also belt driven off the diesel en- 

 gine and supplies 12 cfm. 



TOURS 66: (Fig. 7.15) 



A 28-hp, 3,000-rpm diesel generator is 

 arranged aft in the pressure hull to form an 

 extension of the battery room deck. All pipe- 

 lines connected with the diesel engine (ex- 

 haust gas, fuel, and cooling water) are pro- 

 vided with compensators. A water-cooled ex- 

 haust gas silencer is arranged behind the 

 exhaust gas collecting elbow of the diesel 

 engine. Exhaust gasses are led through an
