FIELD: engines and pumps. ^ SUBSTANCE: method of gas supply to turbine of turbine-pump unit of liquid propellant engine (LPE) consists in preliminary supply of fuel components to mixing head of the device for them to be mixed, further ignition of the obtained mixture and supply of obtained combustion products to turbine blades of turbine-pump unit with their further expansion and emission to atmosphere. For turbine drive of turbine-pump unit there used is some portion of combustion products obtained as a result of fuel component supply to mixing head of chamber, which are taken from combustion chamber; then in addition, one of fuel components is added to them to decrease total temperature of gas flow, and the obtained ballasted gas flow is directed to turbine blades of turbine-pump unit. To the chamber there supplied is flow of fuel components, which is equal to total fuel component flow through chamber for creating the required thrust of flow of fuel components, which is required for turbine drive of turbine-pump unit. ^ EFFECT: simplifying pneumatic-hydraulic system and improving mass-and-dimensions characteristics. ^ 2 dwg |
