Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
79 words
A METHOD FOR GENERATING HIGH-TEMPERATURE GASES FOR THRUST AND GAS GENERATORS COMPRISING INJECTING OXYGEN DIFLUORIDE IN A REACTION CHAMBER AND REACTING SAID OF2 WITH A SEPARATELY INJECTED LIQUID PROPELLANT FUEL CONSISTING ESSENTIALLY OF 85% TO 100% BY WEIGHT OF A HYDROCARBON MIXTURE AND FROM 0% TO 15% BY WEIGHT OF A HIGH ENERGY ADDITIVE, SAID HYDROCARBON MIXTURE CONSISTING ESSENTIALLY OF FROM 20 TO 30 PERCENT BY WEIGHT OF METHANE AND FROM 70 TO 80 PERCENT BY WEIGHT OF ETHANE.
Claim 2

Claim 3
Dependent Claim
147 words
IN A LONG RESIDENT TIME, BIPROPELLANT SPACE VEHICLE COMPRISED OF A THRUST CHAMBER, MEANS FOR STORING A FIRST LIQUID PROPELLANT AND A SECOND LIQUID PROPELLANT AND MEANS FOR SELECTIVELY INJECTING SAID FIRST AND SECOND LIQUID PROPELLANT INTO SAID THRUST CHAMBER, THE IMPROVEMENT WHEREIN SAID FIRST LIQUID PROPELLANT CONSISTS OF OF2, SAID SECOND LIQUID PROPELLANT CONSISTS OF FROM 85% TO 100% BY WEIGHT OF A HYDROCARBON MIXTURE AND FROM 0% TO 15% OF A COMPATIBLE HIGH ENERGY ADDITIVE, SAID HYDROCARBON MIXTURE CONSISTING OF FROM 20% TO 30% BY WEIGHT OF METHANE AND FROM 70% TO 80% BY WEIGHT OF ETHANE AND SAID MEANS FOR STORING SAID FIRST AND SECOND LIQUID PROPELLANTS COMPRISES FIRST AND SECOND SEPARATE CHAMBERS FOR CONTAINING SAID FIRST AND SECOND LIQUID PROPELLANTS, RESPECTIVELY, WHICH CHAMBERS ARE IN PHYSICAL CONTACT SO THAT SAID FIRST AND SECOND LIQUID PROPELLANTS CONTAINED THEREIN ARE IN SUBSTANTIAL THERMAL CONDUCTIVE RELATIONSHIP.
