The utility model discloses a turbine bucket and gas turbine engine for gas turbine engine has base (442) and airfoil (441), base (442) are including cooling air entry (481) and inside cooling air passageway (482), airfoil (441) are including originating in base (442) and terminateeing in internal heat exchange route (470) of the cooling air export (471) of the trailing edge in airfoil (441) (447). Airfoil (441) still contain shell (460) of top wall (461), interior spar (462), nose ribs (472) and leading edge air deflector (475). Nose ribs (472) combine in order to form leading edge cavity (463) with leading edge (446) of shell (460). Leading edge air deflector (475) take shape and fix a position the cooling air who becomes to make to leave leading edge cavity (463) and turn to and spread.
