Analysis on the Power Characteristics of Lift-Fan VTOL
Based on the propeller momentum theory, this paper obtained the momentum model for internal flow of lift fan system. It analyzed the influence of its conceptual parameters on power characteristics of lift-fan VTOL to analyze the trend changes of the total power required with the increase of freestream velocity. The results can be used for selecting parameters at the preliminary phase of designing lift-fan VTOL and determining the design parameters of lift-fan VTOL.
