  • Solid rocket propellant with low glass transition
    Patent number: 11312814
    Abstract: A solid rocket propellant includes a binder that has hydroxyl-terminated polybudadiene (HTPB) with a curative that is selected from isocyanate-terminated polyether, isocyanate-terminated polysiloxane, or combinations thereof.
    Type: Grant
    Filed: September 30, 2016
    Date of Patent: April 26, 2022
    Assignee: AEROJET ROCKETDYNE, INC.
    Inventors: Daniel Doll, Scott Dawley
  • Propellant with extended storage life
    Patent number: 10266458
    Abstract: A propellant includes a binder system that has a polybutadiene component, a polytetrahydrofuran component, and an anti-oxidant component. In an example, the propellant includes a solid oxidizer, a solid fuel, and a binder system that holds the solid oxidizer and the solid fuel together. The binder system includes a polybutadiene component, a hydrocarbon diluent component of a higher level of saturation than the polybutadiene component, and an anti-oxidant component.
    Type: Grant
