In order to analyze economic profitability due to high cruise L/D and higher engine performance of blended wing body (BWB) airliner, the methods of estimating major parameters and calculating flight performance were imposed. Using fuel flow per capita (Fuel/km/seat) as the weighing standard, quantitative analysis was operated on the effects of cruise L/D and specific fuel consumption on 250-seat and 450-seat airliner; then contrasts BWB airliner family with existing equivalent conventional airliner and the material data of economic profitability was obtained. Moreover, analysis was operated on effects of seats and range. In the end conclusion was made on the trend and characteristic of BWB airliner family development and then considering the balance between benefits and realizing difficulty, the reasonable design parameters are given.
