Abstract

Based on the propeller momentum theory, this paper obtained the momentum model for internal flow of lift fan system for analyzing power characteristics in transition of lift-fan VTOL. This paper mainly focused on total lift, total drag and total power during the whole transition with the increase of freestream velocity. The analysis results show the particular characteristics of total drag and total power in transition, which can be used for selecting parameters at the preliminary phase of designing lift-fan VTOL.
