Sonic boom in water?
I have been wondering if a displacement hull that moves fast enough
would create a sort of "sonic boom" just as an object moving fast enough in air does. In air, the shock is created when the aircraft moves too fast for the air to get out of the way. In water, a displacement hull attempts to climb its bow wave which effectively limits its speed. Apparently, this hull speed is not a mathematical limit but merely a practical limit as sufficient power can move a hull over hull speed. However the power necessary to produce any further increase in speed radically increases above hull speed. If you did manage to produce enough power, could you power through the bow wave and thus produce a shock wave? |
