In　this　paper,　a　rotating　blades　equation　is　considered.　The　arbitrary　pre-twisted　angle,　arbitrary　pre-setting　angle　and　arbitrary　rotating　speed　are　taken　into　account　when　establishing　the　rotating　blades　model.　The　nonlinear　PDEs　of　motion　and　two　types　of　boundary　conditions　are　derived　by　the　extended　Hamilton　principle　and　the　first-order　piston　theory.　The　well-posedness　of　weak　solution　(global　in　time)　for　the　rotating　blades　equation　with　Clamped-Clamped　(C-C)　boundary　conditions　can　be　proved　by　compactness　method　and　energy　method.　Strong　energy　estimates　are　derived　under　additional　assumptions　on　the　initial　data.　In　addition,　the　existence　and　regularity　of　weak　solutions　(global　in　time)　for　the　rotating　blades　equation　with　Clamped-Free　(C-F)　boundary　conditions　are　proved　as　well.
