  • Radial turbo machine
    Patent number: 5368440
    Abstract: A radial turbo machine has an impeller and a diffuser with a plurality of airfoil vanes. The airfoil vanes have a design point angle of attack substantially equal to or less than the angle of attack corresponding to the classic onset of pressure side stall of the airfoil vane. The pressure side of the airfoil vane faces away from the rotational axis of the impeller while the suction side faces towards the impeller's rotational axis.
