Abstract

A rocket propulsion oxidizer compound that is a mixture that is a homogenous and stable liquid at room temperature that includes nitrous oxide and nitrogen tetroxide.

Claims

exact text as granted — not AI-modified
1 . An oxidizer compound for use in a rocket propulsion system comprising a mixture that is a homogenous and stable liquid at room temperature wherein said mixture includes nitrous oxide and nitrogen tetroxide. 
     
     
         2 . An oxidizer compound as in  claim 1  wherein said mixture further includes at least one additive having a theoretical specific energy greater than that of said nitrous oxide. 
     
     
         3 . An oxidizer compound as in  claim 2  wherein said at least one additive is an earth-storable oxidizer. 
     
     
         4 . An oxidizer compound as in  claim 1  wherein said liquid is non-viscous at room temperature. 
     
     
         5 . An oxidizer compound as in  claim 1  wherein said liquid is a gel at room temperature. 
     
     
         6 . An oxidizer compound for use in a rocket propulsion system comprising a homogenous mixture that includes nitrous oxide and approximately 28 to 52 weight percent nitrogen tetroxide. 
     
     
         7 . An oxidizer compound as in  claim 6  wherein said mixture is a non-viscous liquid at room temperature. 
     
     
         8 . An oxidizer compound as in  claim 6  wherein said mixture is a gel at room temperature. 
     
     
         9 . A rocket propulsion system comprising:
 a first container;   a rocket fuel stored in said first container;   a second container;   an oxidizer compound stored in said second container, said oxidizer compound comprising a homogeneous and stable liquid mixture at room temperature that includes nitrous oxide and nitrogen tetroxide; and   means coupled to said first container and said second container for controlling mixing of said rocket fuel with said oxidizer compound.   
     
     
         10 . An oxidizer compound as in  claim 9  wherein said mixture further includes at least one additive having a theoretical energy greater than that of said nitrous oxide. 
     
     
         11 . An oxidizer compound as in  claim 10  wherein said at least one additive is an earth-storable oxidizer. 
     
     
         12 . An oxidizer compound as in  claim 9  wherein said mixture is non-viscous at room temperature. 
     
     
         13 . An oxidizer compound as in  claim 9  wherein said mixture is viscous at room temperature. 
     
     
         14 . An oxidizer compound as in  claim 9  wherein said mixture comprises approximately 28 to 52 weight percent nitrogen tetroxide.
