Design methodology and testing of an electro-explosive valve

摘要

An explosively actuated valve has been developed to penetrate a series of aluminum plates and couple a 34 MPa (5000 psi) pressure source to a receiver. During actuation, a plunger with a gas transfer passage is accelerated down a bore and pierces the plates, coupling the pressure source to the receiver. Sealing is accomplished by the plunger wedging itself against the aluminum, preventing the escape of gas through the plates. In this paper the design methodology, calculations, and test results, are presented.
