Analyzing drag characteristics to obtain effective guidelines for configuration design of lift-fan VTOL

The introduction of the full paper discusses relevant matters and then proposes the analysis mentioned in the title. Sections 1 through 3 explain our analysis of the drag characteristics. We believe that all the results of our analysis can serve as effective guidelines for configuration design of lift-fan VTOL. Their core consists of: (1) we establish the aerodynamic estimation model of the lift-fan VTOL; (2) we analyze the effects of conceptual parameters on the peak drag of the lift-fan VTOL in its transition mode. Section 4 presents five conclusions for the results shown in Figs. 2 through 10 in section 3 and three effective guidelines for the configuration design of lift-fan VTOL.
