Appl. No.:

09/670338

Inventors:

Randall J. Cramer - Arlington VA
Susan Peters - Arlington VA

Steve Mitchell - La Plata MD

Assignee:

The United States of America as represented by the Secretary of the Navy - Washington DC

International Classification:

C06D 506

US Classification:

102290, 102288, 102289

Abstract:

Propellant compositions are coated with an energetic deterrent coating which reduces the burning rate at the surface of the propellant grain and causes the propellant to burn progressively. The use of energetic materials, that are slightly soluble in the coating solvent, improve the burning properties of the propellant without decreasing the chemical energy.

Abstract:

A method of making an igniter bag includes (a) providing a first piece of material having a shape of two substantially identical semicircular portions connected along their straight edges by a substantially rectangular portion; the shape defining two opposing three-sided notches, one notch on either side of the rectangular portion; (b) providing a second piece of material having substantially the same shape as the first piece of material; (c) aligning the first piece of material on top of the second piece of material; (d) joining the first and second pieces of material along the three sides of each of the opposing notches; (e) folding the first piece of material such that circumferences of its two substantially identical semicircular portions are aligned with each other and folding the second piece of material such that circumferences of its two substantially identical semicircular portions are aligned with each other; and (f) joining the circumferences of the two substantially identical semicircular portions of the first piece and joining the circumferences of the two substantially identical semicircular portions of the second piece while leaving an opening in one of the first and second pieces.
