In order to explore the influence of the design parameters of the turbo-electric distributed propulsion (TeDP) system on mission fuel consumption, a performance model of the propulsion system and an integrated aircraft-engine evaluation model were established. The influences of the design parameters of the propulsion system on the weight and fuel consumption of the aircraft were studied based on a 150-seats civil aircraft concept. In addition, various operating strategies of battery were analyzed. The results showed that: there existed optimal values of turbine inlet temperature and relative power of electric system to achieve a minimum fuel consumption in mission profile; the energy use of battery should be prioritized to provide power supplementation when the load can't working at full power, which can achieve the reduction of fuel consumption using a battery with energy density higher than 400 W∙h/kg. The integrated design method established can provide supports for the optimization design of the TeDP.
