The TRIZ theory and its solving tools were introduced to the innovation concept design of aero?engine with high thrust-to-weight ratio to meet requirements of future fighter. The conflict of two important problems which aim at the development of high thrust-to-weight ratio engine was analyzed technically, and the corresponding conflict solving principle including the 1st segmentation principle and the 15th dynamic characteristics principle were obtained by using the contradictious matrix. The concept plan for variable by?pass core-driven fan stage (CDFS) turbofan engine was creatively constructed and it can meet the technical requirements of wide envelop and long endurance characteristics for the future high thrust-to-weight ratio engine.
