Design parameter analysis of gas/turbo-electric driven distributed propulsion system
Considering the shortcomings in the design and installation of the reheat gas-driven distributed propulsion system,a partial turbine-electric distributed propulsion system was proposed by combining with the turbine-electric driven.method.A design point calculation model was established based on the component model.The energy flow mechanism of the propulsion system was analyzed,and the design method of key energy transfer parameters was proposed.Based on the research,the influence of design parameters on the propulsion system was analyzed,and the performance and design parameters of different distributed propulsion systems were compared and analyzed.The results showed that the fuel consumption of the partial turbo-electric distributed propulsion system was more sensitive to the turbine inlet temperature,and the total pressure ratio had less influence.Compared with the gas-driven distributed propulsion system,the partial turbo-electric distributed propulsion system had a fuel consumption advantage of 1.7％,and when the power ratio was reasonably selected,it could improve the gas-driven distributed propulsion system.Focusing on the fuel consumption of the propulsion system,the performance suitability of the partial turbo-electric distributed propulsion system based on the gas-driven propulsion system was demonstrated.
