METHOD FOR INCREASING THE SPECIFIC ENERGOMASSOVYH characteristics of liquid rocket engines and liquid rocket engine

摘要

1. A method for improving the characteristics energomassovyh LRE, based on the pressure in the combustion chamber by increasing the pressure of the fuel supply pump components, characterized in that the pressure increase is carried out stepwise over the pumps, several sequentially set main turbopump, except booster, and the quantity of each primary pressure TSNAs optimize pump, coordinating with the characteristics of the previous and subsequent TSNAs, the optimization is performed, including negotiation area and flow ce eniya turbine nozzle main turbopump with the passage section area of ​​the nozzle main TNA.2 later. Expander, comprising a camera main turbopump or primary and booster TSNAs, automation and control units, characterized in that to the output of the main turbopump connected in series at least one primary THA agreed its parameters to the output parameters of the previous TNA.3. LRE claim. 2, characterized in that in each main turbopump, parallel to the turbine pipe docked with the working fluid bypass configuration elements governing perepuska.4 degree. LRE claim. 2, characterized in that the output line of the first main pump turbopump connected with the input highways subsequent pump core THA, and the output line of the first turbopump turbine associated with the input highways subsequent turbopump turbine.
