Classes of SSN (Hunter Killer) 3rd Generation
What Happens Underwater
The Trident Missile
The Deterrent
THE SUBMARINE MUST BE ABLE TO:
Maintain watertight integrity Withstand pressure at depth Remain manoeuvrable Provide a stable platform to carry and fire weapons Provide a habitable environment for the crew and to house machinery Remain undetected - Very quiet Work independently of air
TRIM SYSTEM
BILGE SYSTEM
The primary function of the Bilge System is to collect and store dirty water & other fluids prior to subsequent discharge overboard.
• • • SS: SSN: SSBN: Submarine Submarine (Nuclear Propelled) Submarine (Nuclear Propelled with Ballistic Missiles)
•

FF:
DD: DDG: CV: CVF:
Frigate
Destroyer Destroyer with Guided Missiles Carrier Carrier with fixed wing aircraft
FOREPLANES
Work in conjunction with the after planes to control pitch and depth
AFTERPLANES
Work in conjunction with the fore planes to control pitch and depth
HP BLOW SYSTEM
NUCLEAR STEAM RAISING PLANT
The pressurised water reactor generates heat to boil water,producing steam to drive the main turbines for propulsion and the turbo generators for electrical generation.
• HMS Trafalgar (T boats)
• HMS Turbulent
• HMS Tireless • HMS Torbay • HMS Trenchant • HMS Talent • HMS Triumph
• Astute (A Boats)
Tomahawk Land Attack Missile Fired from HMS Splendid
The PWR is the submarines main source of power:it uses nuclear fission to generate the heat that is used to produce steam.
Missile in Flight
One Less Command Bunker
HMS VANGUARD (SSBN)
Classes of SSBN (Bomber)
• HMS Vanguard (Trident)
• HMS Victorious • HMS Vengeance • HMS Vigilant
BALLAST SYSTEM
The primary function of the Ballast System is to adjust the bodily weight of the submarine.
BALLAST SYSTEM
TRIM SYSTEM
The primary function of the trim system is to adjust the horizontal plane of the submarine.
Compressibility Down & Out Up & In
SUBMARINE STABILITY
The Centre of Gravity is the point through which the entire weight of the submarine may be said to act.

BALLISTIC MISSILE SUBMARINE COMPARTMENT LAYOUT
ACCOMODATION/FOREENDS
OPERATING ZONES
• NORMAL OPERATING ZONE
• MAXIMUM EXCURSION DEPTH (20% BELOW DDD)
• CRUSH ZONE
CONTROL SURFACES Control the submarine’s Course and Depth
SEA PRESSURE INCREASES AS THE SUBMARINE GOES DEEPER.
The Problem:
:
In PSI, pressure is approximately equal to ½ the depth in FEET. At 100ft sea pressure is: 50 PSI
BILGE SYSTEM
DOMESTIC FR来自百度文库SH WATER
The function of the domestic fresh water system is to provide hot and cold fresh water for drinking,domestic and other purposes.
FIN
Integral with the casing is the FIN. It has 3 distinct functions:
• Supports and houses the masts and periscopes. • Provides an elevated platform for conning and navigation. • Strengthened for icebreaking and streamlined by shutters.
In BAR, pressure is approximately equal to 1/10 of the depth in METRES. At 30m sea pressure is: 3 BAR
At a submarine’s Maximum Operating Depth a submarine is having to withstand pressures of 650 psi or 35 Bar
RUDDER
Controls the Heading of the Submarine

HIGH PRESSURE AIR
To supply clean dry air @276 bar to:
A)
Main Ballast Tank blows.
B)
C) D)

Auxiliary Vent & Blow. After Planes in air emergency.
Is the point through which the entire upthrust on the submarine may be said to act
STABILITY
Stability is the submarine’s resistance to heeling forces

HMS TRAFALGAR (SSN)
A Submarine is only ever called a: BOAT
Naval Terminology Designed to Confuse
MASTS & PERISCOPES
SUBMARINE SYSTEMS
In order to operate efficiently and independently, the submarine needs :
• Water systems • Air systems • Hydraulic systems • Environmental systems • Sanitary systems
All heavy machinery and weights are placed at the bottom of the submarine to keep the centre of gravity as low as possible,this improves stability.
THE CENTRE OF BUOYANCY:

BASIC SUBMARINE CONSRUCTION
THE STRENGTH OF THE HULL IS INCREASED BY ADDING:
T Frames
Bulkheads
Decks
Numerous holes are cut into the pressure hull for access and services,all of which weaken the pressure hull. In order to restore it to its original strength, heavier plating is welded around each opening,these plates are known as:
