Abstract

A liquid monopropellant composition comprising the water solution of an hydroxylammonium nitrate and a compatible water soluble or water dispersible fuel.

Claims

1. A liquid monopropellant composition comprising:

(1) an oxidizer selected from the group consisting of hydroxylammonium nitrate and the N-methyl, N-ethyl, O-methyl and O-ethyl derivatives thereof;

(2) a compatible fuel selected from the group consisting of (a) water soluble fuels selected from the group consisting of nitrates, ethers, nitriles, hydrolyzed polyvinyl acetates, polyacrylic esters, polymethacrylic esters, polyhydric alcohols, monohydric alcohols, amides, amines, amino acids, sulfoxides, sulfones, Ketones, sugars and mixtures thereof and (b) water dispersible fuels selected from the group consisting of fuel oil, JP4 fuel, diesel fuel and commercial tall oils; and

(3) water;

wherein said oxidizer, fuel and water are present in the weight ratio of 1;

9;

10 to 17;

1;

2.

2. The liquid monopropellant of claim 1 wherein the compatible fuel is a water soluble fuel.

3. The liquid monopropellant of claim 1 wherein the fuel is a water dispersible fuel containing a minor portion of a suitable surfactant.

4. The liquid monopropellant of claim 1 wherein said oxidizer is hydroxylammonium nitrate.

5. The liquid monopropellant of claim 1 wherein the oxidizer and fuel are present in approximately stoichiometric amounts.

6. The liquid monopropellant of claim 2 wherein said water soluble fuel is selected from the group consisting of isopropylammonium nitrate, methylammonium nitrate, ethylammonium nitrate, diethylammonium nitrate and ethylmethylammonium nitrate.

7. The liquid monopropellant of claim 2 wherein said water soluble fuel is dioxane.

8. The liquid monopropellant of claim 2 wherein said water soluble fuel is isopropylammonium nitrate.
