Supersonic compressor and method associated with it

FIELD: machine engineering.

SUBSTANCE: rotor of the supersonic compressor and a method for compressing fluid are disclosed. The rotor comprises first and second rotor discs, a first set and a second set of rotor blades. The first set and the second set of rotor blades are connected to the first and second rotor discs and arranged therebetween. In addition, the first set of rotor blades is offset from the second set of rotor blades. The rotor comprises a first set of flow passages defined by the first set of rotor blades located between the first and second rotor discs. Similarly, the rotor comprises a second set of flow passages defined by the second set of rotor blades located between the first and second rotor discs. In addition, the rotor has an inclined compression section located on the rotor blade surface opposite to the surface of adjacent rotor blade.

EFFECT: increased efficiency.

Compression unit // 2455530

FIELD: machine building.

SUBSTANCE: compressor unit (1) comprises a compressor (5), a suction line (2) and a return line (3), a block (20) that controls the compressor (5). Moreover, in line (2) the suction is ensured by at least one device (21, 22) to detect amounts of non-gaseous fluid medium in the fluid to be compressed, on their way to the entrance to compressor (5), and detection device (21, 22) is connected to management block (20) ensuring signal transmission, and compressor unit (1) contains dissolution unit (30), which dissolves the amount of non-gas on its way to the entrance of compressor (5), while the dissolution is initiated when the amount of detected non-gaseous fluid exceeds a certain limit.

EFFECT: any damage caused by a number of non-gaseous fluid into the suction inlet to the compressor is excluded.

FIELD: aviation.

SUBSTANCE: proposed method includes suction of air from upper surface of wing by means of impeller of centripetal fan and directing this air flow under lower surface of wing with the aid of centrifugal fan impeller. Air flow formed in radial direction relative to annular wing having asymmetric profile creates lifting force due to difference in pressures on lower and upper surfaces of wing.

EFFECT: enhanced efficiency of creating lifting force.

FIELD: ventilation.

SUBSTANCE: invention relates to a centripetal delivery compressor for the ventilation system, comprising: a casing, an air inlet in the casing, an air outlet in the casing, an impeller, and a blade drive, at that the layer of centrifugal blades and the layer of centripetal blades are arranged on the inner side of the impeller, the layer of the centrifugal blades and the layer of centripetal blades are staggered at intervals in the axial direction. The centrifugal blades form a centrifugal channel, and the centripetal blades form a centripetal channel. The guide walls for protection of the impeller edges from the air flow are arranged on the outer sides of the centrifugal channel and the centripetal channel, and the reverse channels of the impeller edge are arranged between the guide walls for protection of the impeller edge from the air flow and the centrifugal blades and between the guide walls for protection of the impeller edge from the air flow and the centripetal blades.

EFFECT: obtaining a compressor of simple design, high efficiency, and a wide range of applications, energy saving.
