DEFINITION

Classification: 60/212

(under subclass 211) Process directed to utilizing an extraneous material to aid the ignition of the fuel and oxidizer mixture in the reaction zone.

(1) Note. The igniter aid includes (1) a coating in the reaction zone which catalyzes the reaction between the fuel and oxidizer, (2) a hypergole added to the oxidizer or the fuel for starting or (3) a material separately injected into the reaction zone.

(2) Note. A patent which claims a material as a pure fuel and as a part of a fuel mixture even if it improves the ignition characteristics of the main fuel is classified in subclass 211 and cross-referenced to subclass 215.
