초록

A solid propellant grain which comprises an homogeneous mass of propellant material including an oxidant. A variable burn rate is provided by embedding a reticulated structure in a portion only of the propellant mass. The reticulated structure may be coated with a high thermal conductivity material to provide an increased burning rate. The coat of material is selected to preferably provide improved bonding to the propellant mass.

청구항

A variable burn rate solid propellant grain comprises: an homogeneous mass of propellant material including an oxidant, said propellant mass includes at least one first portion and at least one second portion; and at least one three-dimensionally reticulated structure which is embedded in said first portion only of said mass and which is distributed throughout the same volume as said first portion of said mass is distributed, said second portion of said mass being free of three-dimensionally reticulated structure whereby the first portion burns with a di...
