  • Process for assessing the effect of propellant strain on propellant burn rate
    Patent number: 4815315
    Abstract: The present invention describes a process for relating burn rate in a sample propellant to a strain field imposed therein by bending the sample propellant by a determined amount. The propellant is cast upon an initially flat plate having a single pair of fixed parallel walls. The plate is bent parallel to the walls before the test burn. Measurements of the thickness of the propellant before the burn and after the burn are related to the strain placed in the propellant by the bending. All measurements occur when the plate is flat.

  • High propellant mass fraction highly stress relieved end-burning grain structure
    Patent number: 4696233
    Abstract: An end-burning grain structural arrangement for a solid rocket propellant is formed by two parallel inhibited grain components formed into an "S" shaped cross section. The components form a fully case bonded system and the two components are separated from each other along the "S" which provides stress relief.
