ABSTRACT:
A jet blast deflector fence comprising two curved corrugated deflecting surfaces separated from each other in a common structural framework that is fastened to a concrete foundation, with the taller front deflecting surface open at the bottom to permit the high speed jet exhaust ground layer component to split off and pass through the opening to impinge upon the shorter rear deflecting surface which deflects that component vertically upward to hug the convex rear surface of the front deflector, while the upper slower moving component of the jet blast is guided upwardly by the concave surface of the front deflecting surface such that the two split layers come together in a substantially vertical direction at the discharge edge of the taller deflecting surface to form a vertical air curtain which aerodynamically increases the effective height of the blast deflector.
