Beschreibung
Zusammenfassung:	transport engineering; gas turbines. SUBSTANCE: proposed cooled blade of gas turbine has hollow air foil portion with radial dividing partition in upper section of which, between end of radial partition and end face wall of air foil portion, turnable rib is made. In front space tilted semiribs are provided which are installed on concave and convex walls of blade and are interconnected by dowels. Semiribs on convex wall are tilted at acute angle to leading edge. Cylindrical dowels are installed in rear space of air foil portion. Semiribs on concave wall are tilted at obtuse angle to leading edge. Radial projection in rear space of air foil portion is connected with concave wall by pins. Leading edge is provided with cross ribs whose base is located in point of intersection of surface of leading edge with longitudinal axis of semiribs located on concave wall. Turning rib is provided with hole opposite to end of radial partition. EFFECT: improved cooling of blade. 2 dwg
