  • US Patent:
    54178959, May 23, 1995
  • Filed:
    Jan 23, 1990
  • Appl. No.:
    7/473254
  • Inventors:
    Adolf Oberth - Fair Oaks CA
  • Assignee:
    Aerojet General Corporation - Sacramento CA
  • International Classification:
    C06B 2100
  • US Classification:
    264 31
  • Abstract:
    Solid composite propellants are prepared by combining solid fuel and oxidizer particles, hydroxy-terminated prepolymers, and bonding agents which have polar functional groups to bond to the oxidizer particles and hydroxyl groups converted to isocyanate groups to bond to the binder. These bonding agents replace the non-reacted precursors as well as aziridine-type bonding agents in common use.

  • Filed:
    Nov 5, 1990
  • Appl. No.:
    7/616571
  • Inventors:
    Rolf Sylvester Bruenner - Orangevale CA
    Adolf Eduard Oberth - Fair Oaks CA

  • US Patent:
    40381145, Jul 26, 1977
  • Filed:
    Aug 20, 1976
  • Appl. No.:
    5/716305
  • Inventors:
    Adolf E. Oberth - Fair Oaks CA
  • Assignee:
    The United States of America as represented by the Secretary of the Air
    Force - Washington DC
  • International Classification:
    C06B 4510
  • US Classification:
    149 194
  • Abstract:
    A catalyst system for promoting the room temperature of isocyatic cured polyurethane based propellants. The system is composed of a metal catalyst; a chelating agent or an acid as a suppressor component; and zinc oxide as a scavenger component. The suppressor inactivates the catalyst, thus providing the necessary potlife, while the scavenger slowly consumes the suppressor, thus restoring the activity of the catalyst, which then promotes an effective cure.
