Appl. No.:

8/183711

Inventors:

Wayne C. Fleming - Glendale AZ

Assignee:

Universal Propulsion Company, Inc. - Phoenix AZ

International Classification:

C06B 4510

US Classification:

149 194

Abstract:

A propellant with a long shelf life that is smoke-free when combusted. The propellant may have the following composition when the propellant includes a reinforcing agent. ______________________________________ Approximate Percentage Material Range by Weight ______________________________________ Ammonium nitrate 40-85 Binder (with curvative) 4-40 Energetic plasticizer 0-40 Reinforcing agent 0. 1-8 ______________________________________ When the reinforcing agent is included in the propellant, a desiccant in the range of 0. 02-6% may or may not be included in the propellant. The binder is selected from the group consisting of a thermoplastic material such as Finaprene. RTM. or Kraton. RTM. (e. g. thermoplastic elastomers) or a cure-hardening material or a combination thereof.
