EXPLOSIVE FORMING OF CLOSURES FOR LARGE SOLID PROPELLANT MOTOR CASES.
Abstract
The application of ice die and free-forming tech niques to produce large closures by the explosive forming process is described. Problem areas associated with steel procurement, blank process ing, and die fabrication are also presented in detail with recommended solutions where appli cable. The successful use of welded blanks in conjunction with explosive forming is described. The behavior of 18% nickel maraging steel sub jected to high strain rates is evaluated. The application of explosive welding techniques to the 18% nickel maraging steel is discussed, and some of the effects on structure and preliminary evaluations of weld strength are presented. Problems associated with the extension of the work performed in this program to the 160-inch diameter size are described in detail and fabri cation procedures for use in the 160-inch dia meter chamber are detailed.
