FIELD: compressors. SUBSTANCE: blades made integral with a carrying disk are located in the compressor wheel between riveted covering and carrying disks. The blade thickness is determined from a relation 
where 
is a particular blade relative thickness; 
= 0.015 -0.018 for the wheel with aerodynamic structural parameters: 
is a particular blade relative thickness, 
= 0.021-0.022 for the wheel with wear-resistant structural parameters; D is the outer diameter of the wheel. The axis of each rivet is spaced apart from the back side of the blade at a distance of S = (0.015-0.018)R where R is the outer wheel radius. EFFECT: improved structure. 3 dwg
