  • Detonation Engine having a Discontinuous Detonation Chamber
    Publication number: 20210372324
    Abstract: A detonation engine includes at least one chamber wall and a first detonation chamber defined by the at least one chamber wall, the first detonation chamber having a first end and a second end. The first detonation chamber is linear, curved, or includes a plurality of detonation chamber segments that are linear and/or curved, and the detonation engine is configured such that detonation repeatedly propagates from the first end of the first detonation chamber to the second end of the first detonation chamber.

  • Composite solid rocket propellant with DCPD binder
    Patent number: 8192567
    Abstract: A composite solid rocket propellant comprising a fuel, an oxidizer and a dicyclopentadiene binder is provided. The dicyclopentadiene binder may be mixed with the fuel and oxidizer as a monomer and then polymerized after mixing to form the composite solid propellant. The composite solid propellant may also comprise plasticizers, triphenylphosphine, lecithin or combinations thereof. Methods for making the composite solid rocket propellant of the present invention are also provided.
