<p>The blade has a tubular sleeve (24) housed in a cavity (26) provided with ends (243, 244) in respective openings (29, 30) and made of metallic sheet, where the blade is arranged such that sleeve is introduced by the opening (29). Spacers e.g. bosses (241) and projections (25) are arranged at sides of the respective openings and arrange a space between an outer surface of the sleeve and a wall of the cavity. The spacers are integrated to the wall of the cavity along a vane (20). The spacers are arranged along a direction forming an angle with a chord of the blade. An independent claim is also included for a method of assembling a cooled blade.</p> |
