DEFINITION

Classification: 60/257

(under subclass 200.1) Apparatus in which thrust is produced by the combustion of (1) a monopropellant or (2) an oxidizer and a fuel, the oxidizer being supplied to the combustion zone in a liquid state.

(1) Note. This definition is intended to provide an art collection of nonair breathing motors (i.e., rockets) employing an oxidant supplied to the motor in a liquid state. However, no special structure need be claimed for classification in this subclass. Patents whose disclosure or claims relate to the described art group are considered to come under this definition.

(2) Note. A broad disclosure that liquid oxidizer, two or more liquid propellants or liquid monopropellant are used in the motor or that the motor is of the "liquid propellant or liquid reactant" nonair breathing type is classifiable under this definition.
