Beschreibung
Zusammenfassung:	FIELD: drilling. ^ SUBSTANCE: vortex pressure turbine stage comprises of the hub of the stator. The blade rim of the stator is fitted into the hub. The blades of the stator blade rim has a chord of the blade profiles which is inclined to the plane perpendicular to the longitudinal axis of the pressure turbine stage under an angle which does not exceed 50o. The stator rode and rim receive the rotor pressure turbine stage which has the hub. The blade rim is mounted on the hub by a pressed fit. The inclination of the blades of the rotor rim ranges from 40 to 80o. The outer side of the blades is concave. ^ EFFECT: enhanced efficiency. ^ 6 dwg
