The invention provides a rotational flow blade of a combustion chamber of a ground gas turbine. The rotational flow blade is mainly used in a head main-combustion-level whirlcone of the combustion chamber of the ground gas turbine. The cross section of the rotational flow blade is in a wing shape, a groove and boss structure is adopted in the blade surface on the windward face, and turbulent transition is promoted to occur in advance. A flow separation phenomenon is not likely to happen to a turbulent boundary layer, and therefore a low-pressure area on the back of the blade is reduced, and resistance is reduced. Meanwhile, the turbulence intensity is increased, the premixing evenness of fuel in the main whirlcone can be improved, the combustion evenness of a main combustion area in the combustion chamber is effectively improved, a local high temperature area is avoided, and the emission of NOx is greatly reduced.
