DEFINITION

Classification: 60/219

(under subclass 205) Process directed to reacting solid material in the reaction zone.

(1) Note. Producing thrust (1) by burning a cast monopropellant in the reaction zone, (2) by jetting a fuel onto solid oxidizer in the reaction zone, (3) regulating reaction rate of the solid propellant material in the reaction zone by injecting a fluid to change the pressure in the reaction zone are nonlimiting examples of processes within the scope of this and indented subclasses.

SEE OR SEARCH THIS CLASS, SUBCLASS:

217, for a process in which a solid propellant material is extruded into the reaction zone.
