Abstract : To design a solid propellant grain is to conceive and to define a grain which satisfies various requirements. This paper describes the methods and procedures which are used today in France to design propellant grains. It describes and analyses: (1) The various types of grain and the various families of propellant which are available and used today; (2) the detailed requirements that a solid propellant grain must satisfy; (3) the methods which are used to precisely define the propellant, the architecture and the configuration of the grain, and more specifically the methods used in order to ensure required ballistic performances though maintaining structural integrity of the grain (which is submitted to mechanical loads all along its life); and (4) an overview on a method of solid propellant grain reliability assessment. Lastly, the improvements needed in the area of grain design analysis and the related technical breakthroughs are briefly presented.
