The invention discloses a method for matching blade layout and nozzles of a blade type radial swirler, belongs to the technical field of aero-engines and gas turbines, and at least partially solves the technical problem of low design efficiency in the prior art. The effective circulation area ACds of the radial swirler is determined according to the pneumatic design value of the engine combustion chamber; the relation among the effective circulation area ACds, the blade width B of the swirler, the blade number n and the minimum throat distance S of the blades meets the formula: ACds = n * B * S * Cds, wherein Cds is the air flow coefficient of the radial swirler; the distance L between the nozzle and the throat of the venturi tube of the blade type radial swirler and the diameter D of the throat meet the carbon deposition design criterion of the venturi tube and the nozzle, so that the layout of the blades is matched with the position of the nozzle, and after the blade type radial swirler ...
