Application of multipropellant fuel in rocket engines

Modifying the fuel composition for both the liquid rocket engines and solid-propellant rocket engines as well as improving the operating process in the combustion chamber of the propulsion installations are the most essential development trends of the rocket engine manufacturing. One of the development areas in this field is construction and improvement of the rocket engine operating on the multipropellant fuel with regard to the rocket, aerojet and hydro jet engines. The article analyzes the propulsion installation operating on the pseudoliquified powdered metalized fuel, where either the air or water is used as an oxidizing ingredient. The paper concerns issues related to the feed, ignition and burning of the powdered metalized fuel as well as the removal of the condensated combustion products from the combustion chamber (K-phase). We present some results of chemical and disperse analysis of the condensated phase within the composition of the rocket fuel combustion products.
