ROCKET PROPULSION UNIT WITH SOLID FUEL DISPERSING DEVICE Russian patent published in 2020 - IPC F02K9/70 F02K9/24 

FIELD: missiles.

SUBSTANCE: invention relates to aerospace engineering, particularly, to rocket engines. Rocket propulsion unit with solid fuel dispersion device includes housing filled with solid fuel, nozzle unit with combustion chamber, as well as piston, turbines and gas reducer. Device for dispersing solid fuel is made in the form of preliminary and dispersing grinders. Piston is configured to supply solid fuel to the pre-crusher under the action of gas fed through the gas pipeline from the combustion chamber. After the preliminary grinder the fuel is supplied through the guiding funnel to the dispersing grinder and then through the funnel into the combustion chamber. Turbines are configured to actuate each of the grinders under the action of the gas coming from the combustion chamber, wherein the gas from the combustion chamber is supplied to the turbines and the piston through the gas reducer.

EFFECT: invention increases stability of combustion of solid fuel and reduces requirements for temperature and moisture conditions of storage of missiles.
