FIELD: manufacture of air craft engines, namely manufacture of gas-turbine engine blades of materials that may be deformed in hot or cold state.

SUBSTANCE: method comprises steps of turning each cross section of blade (at initial manufacture of blade) around its mass center and increasing distance between two similar points of corrected and basic sections by value of reducing said distance at twisting blade; removing rough allowance before twisting blade. Method provides possibility for making blades of large size and large twisting angle and also blades with sections whose mass centers are not laid in the same straight line from blank with profile of cross sections as mush as possible alike those of ready blade.

EFFECT: possibility for making large-size blades, elimination of complex operation of milling blades needing special equipment.
