In order to evaluate the influence of distributed propulsion, a calculate model of aircraft fuel consumption is established based on the model of propulsion system. The specific fuel consumption of distributed propulsion is calculated to survey the effects of transmission loss and bypass ratio. Fuel consumption is compared with that of a baseline engine to research the effects of additional weight and energy loss from electrical system. Improvement of aerodynamic performance and structure weight due to distributed propulsion are considered in the calculation of fuel consumption to analysis the combined effects of distributed propulsion. The transmission efficiency and power density of the electrical system required to reduce fuel consumption under different income levels are clarified. The results provide references for parameter optimization of distributed propulsion systems and aircraft design.
