DEFINITION

Classification: 60/211

(under subclass 205) Process directed to injecting into the reaction zone separate streams of fuel and oxidizer.

(1) Note. The injection of separate streams of at least two different substances which react to produce products which are useful to generate thrust is considered injecting separate streams of fuel and oxidizer. The two substances may ignite on contact (hypergolic reaction) or they may be caused to react by various means, such as; a catalyst, an electrical discharge, heat, a substance which is hypergolic with either reactant or the reactant mixture.

(2) Note. For purposes of this and indented subclasses red fuming nitric acid, white fuming nitric acid, fuming sulfuric acid and aqueous hydrogen peroxide are arbitrarily considered pure substances.

(3) Note. For purpose of this and indented subclasses a solution of an amine base in an oxidizing acid is considered a pure substance regardless of the ratio of amine to acid.
