Feasibility Study of a Fast Acting Valve for the LB/TS (Large Blast/Thermal Simulator).

Abstract

This study explores the feasibility of using a sliding sleeve concept to produce a high-pressure, large-diameter valve which can be rapidly opened or closed. It was studied for application as a starting device at the outlet of a pressurized driver tube in a shock down type wind tunnel. Charge pressures of 2500 psi, valve sizes equivalent to a 36-inch diameter clear opening and opening times of 50 milliseconds or less were found to be obtainable. A valve with these characteristics was conceptually designed. Successful experience with smaller valves based on the same concept and problems associated with scaling up these designs are discussed. A development program which addresses these problems is proposed, and current costs for such a valve and development program are established.
