METHOD TO OPERATE OXYGEN-KEROSINE LIQUID-PROPELLANT ROCKET ENGINES AND FUEL COMPOSITION THEREFOR

摘要

FIELD: engines and pumps.;SUBSTANCE: proposed method is based on using fuel additive that makes a coolant intended for chamber cooling and is introduced into gas generator that incorporates line feeding fuel from pressure lines of oxygen and kerosene feed burnt at stoichiometric ratio. Note that said fuel additive is used for ballasting of "neutral gas" and reducing of its temperature to values allowed by turbine structural materials. Note also that produced gas is fed into combustion chamber, together with oxidiser and fuel. Mind that said fuel additive represents liquefied ammonia (NH₃) in amount of 10% to 35% of total weight flow of fuel, while gas with aforesaid additive is burnt in engine chamber. Fuel composition for oxygen-kerosine liquid-propellant rocket engines contains liquefied oxygen and liquid kerosine as well as fuel additive improving perfomances of engines represented by liquefied ammonia (NH₃) in amount of 10% to 30% of total weight flow of fuel.;EFFECT: improved performances of proposed engines.;4 cl, 2 dwg
