Part 5/7:
A fascinating aspect of submarine operation discussed is the diving process. The vessel prepares for submersion by sealing all intakes and allowing water to flood into the ballast tanks, facilitating negative buoyancy. Adjustments are continually made with the bow and stern planes to maintain desired trim and depth, ensuring that the submarine can adapt to ocean conditions.
Engine and Power Systems
Further exploration leads to the engine room, where diesel engines power the submarine. O’Neal notes the unique opposed piston design, emphasizing the balance achieved by engines rotating in opposite directions. The switch from diesel to electric powers during submersion showcases the engineering ingenuity that maximizes stealth and efficiency.
