FIELD: engine maintenance.
SUBSTANCE: invention relates to the non-destructive inspection through the radiography of a gas turbine engine blade made from composite materials. A control sample of a blade is manufactured from composite materials to standardise the radiographic inspection of such blades. A three dimensional raw piece is braided from composite materials and elements made from resin are positioned in certain points of the piece. The raw piece is then placed into the casting box and then resin is fed to the casting box to produce the control sample of the blade.
EFFECT: standardisation of the engine blade radiographic inspection for a distinctive flaw - accumulation of the resin inside the blade.
