Hydrostatics and Control,ht of the displaced fluid, (displacement). There are two different definitions of submerged displacement: one that doesn’t include the mass of fluid in the free flooding spaces (hydrostatic displacement), which is used by submarine naval architects, and one that does include the mass of the fluid in

Manoeuvring and Control,e forces and moments on the submarine. Means of determining the coefficients using model tests, including a rotating arm and a planar motion mechanism, are detailed. In addition, the use of Computational Fluid Dynamics; and empirical techniques for determining the manoeuvring coefficients are discus

Resistance and Flow,clude: surface friction; form drag; induced drag; and wave making resistance. The latter only becomes important when the submarine is operating on, or close to, the water surface. The flow over a submarine will influence its top speed, its acoustic signature, and the effectiveness of its own sensors

Propulsion, aft body and the tail cone angle; the casing; the sail; and the aft appendages. There will be an uneven wake field into the propulsor which will depend on the sail design and aft control surface configuration. This will result in fluctuating forces, causing vibration and noise. The quality of the f

Hydro-acoustic Performance,hydro-acoustic point of view. Hydroacoustic noise generated directly by a propulsor can be categorized into: cavitation noise; narrowband, (or tonal), noise; and broadband noise. Each of these is discussed briefly. It is noted that if cavitation occurs it will dominate all other sources of noise. Ca
