U.S. Navy Tests New, Sleeker Railguns

The first of two new prototype railguns is now firing bullets, moving the U.S. Navy’s long-held dream of fielding an electromagnetic weapon a step closer to reality.

A 32-megajoule “prototype demonstrator” made by BAE has already been fired six times in a week, officials told reporters during a Feb. 28 teleconference.

	CFD analysis of the control valve for hydraulic braking system In the current work a full-scale CFD model of the control valve considering all its geometrical features was developed. As a result of CFD simulation the distributions of velocity and pressure within throttling cavity of the control valve were obtained. The relationships of pressure drop characteristics to the flow rate and valve piston positions were calculated.
Keywords:	CFD, control valve, hydrodynamics, pressure drop characteristics
Element Type/Problem Type:	Tetrahedral with prism near wall layers
