  1. MESA-MESC TECHNICALSESSION ON SUBMARINES By ShantanuMainkar Technical Service Director

  2. SIX KEY STAGES IN DEVELOPMENT OF SUBMARINE

  3. TURTLE

  4. Designed such that man can sit within vessel carrying a bomb under water Produced from wood Buoyancy principle Propelled by muscle power Supply of oxygen under water Less supply of air (only for 25 mins) Loss of consciousness Each member needs 12m3/day at least TURTLE

  5. ELECTROLYSIS

  6. ELECTROLYSIS SYSTEM

  7. Supplies 4000 lit oxygen per hour Oxygen to replenish still air By using this system limit less supply of air ELECTROLYSIS SYSTEM

  8. SPAR TORPEDO

  9. MANOEUVRABILITY

  10. USE OF FINS

  11. Inspiration from nature To control depth and angle of attack USE OF FINS

  12. MODERN FINS

  13. Electronically controlled Another pair present at back like planes MODERN FINS

  14. HOW THIS HAPPENS

  15. TORPEDO

  16. Have propellers and control surfaces at back Have large warhead Only two hits required to sink large ships Captain has to aim ahead of his target TORPEDO

  17. Is guided with help of optical fibre GUIDED TORPEDO

  18. GUIDED TORPEDO

  19. Submarines were able to fire two torpedoes a Special submarine developed by Germans called as Milkcow Can hold 4000 tons of fuel But it was taking 5 hours to refuel submarine So were vulnerable to areal attacks as both subs had to come above water for refueling NEED OF FUEL

  20. MILKCOWS

  21. RISE OF NUCLEAR SUBMARINES

  22. First tried by Americans named as USS Nautilus Can travel 1000 km on 4 kilograms of uranium Travelled 3400 km under polar ice Submarine that could operate anywhere in the world Today’s reactors are far more powerful. e.g. Reactor on Pennsylvania is able to run all machines on submarine (including washing machines required for crew). But the reactor is yet to be refueled since last 20 years. NUCLEAR SUBMARINES

  23. So fuel for crew i.e. food is limitation of Pennsylvania rather than fuel for submarine It carries 3 months food supply Food is also important morale booster for crew

  24. Russian submarine exploded its crew took too long to control fire So fire control trials are arranged on submarine regularly in which crew members have to control fire within 6 minutes. PROTECTION AGAINST FIRE

  25. Subs were difficult to find. So it provided perfect base to launch an attack. Russians were first to do so. NUCLEAR STRIKE FROM SUBMARINE

  26. NUCLEAR STRIKE FROM SUBMARINE

  27. But Americans wanted to design subs which can fire missile under the water. But rockets needed air to burn so they won’t work under the water. NUCLEAR STRIKE FROM SUBMARINE

  28. ANSWER BY USING MODEL ANALYSIS

  29. By using this missile can get velocity of 80 kph which can cut through 14 m of water Nuclear weapons on these submarines are more destructive than all the bombs dropped in both world wars combined ANSWER BY USING MODEL ANALYSIS

  30. TRIAL OF LAUNCHING NUCLEAR MISSILE

  31. Submarine should be undetectable But sound can travel under the water So to make all machines silent, all are insulated with rubber shock absorbers But they can be detected with help of bubble trails Stealth MODE

  32. CAVITATION

  33. Design of new propeller

  34. Any questions?

  35. thank YOU
