Abstract
Results of search and analysis of Polish disclosed secret patents on manufacture technology of solid, heterogeneous rocket propellants, were presented. As a result of this search, fifteen patent descriptions of inventions were found. These inventions were applied as secret ones to the Polish Patent Office in years 1963-1997. Information pieces about their disclosure, i.e. about removing secrecy from them, were published in the announcements of the News of the Polish Patent Office issued in years 2007-2017. Main topics of these inventions related to the ways of obtainment of compositions and charges of solid, heterogeneous rocket propellants, their inhibitors (screening compositions) covering propellant charges, and use of silver thin wires and/or catalysts accelerating combustion of such type propellants.
