The　Froude-scaled　offshore　floating　wind　turbine　model　is　inevitably　affected　by　the　Reynolds　number　effect,　making　the　model　unable　to　correctly　reproduce　the　thrust　performance　of　the　reference　wind　turbine　(RWT).　To　solve　this　problem,　an　Xfoil-AirfoilPrep-Matlab　(XAM)　system　and　a　wide　tip　speed　ratio　search　method　(WTSM)　are　proposed　to　design　a　wide　tip　speed　ratio　(TSR)　thrust-match　model　blade.　The　XAM　system　is　utilized　to　select　the　best　airfoil　for　WTSM　by　calculating　the　lift　and　drag　coefficients　of　several　airfoils.　The　WTSM　is　utilized　to　optimize　the　blade　chord　and　twist.　It　formalizes　the　blade　chord　and　twist　by　polynomials　and　then　optimizes　the　polynomial　coefficients.　The　thrust　coefficients　construct　the　optimization　object　at　different　TSRs.　For　validating　the　effect　of　the　redesigned　blade,　the　thrust　performance　is　compared　to　that　of　the　RWT　blade.　In　addition,　the　thrust　performance　of　redesigned　blade　at　different　pitch　angles　is　also　calculated　and　compared　to　those　of　the　RWT　blade.　Results　show　that　the　thrust　performance　of　redesigned　blade　matches　well　with　that　of　the　RWT　blade　at　0　pitch　angle,　and　it　can　also　match　the　variations　of　that　of　the　RWT　blade　at　the　other　pitch　angles　well.
