24 Jun 1991TL;DR: In this article, a radial inflow particle separator (40) is employed with a turbine engine, which is operated at times in an environment laden with dust and particulate matter.
Abstract: A radial inflow particle separator (40) includes a pair of axially and radially spaced curvilinear walls (42, 44) cooperatively defining a circumferential flow path (16) leading radially inwardly and axially to an engine. Preferably, the particle separator (40) is employed with a turbine engine (10) which is operated at times in an environment laden with dust and particulate matter. Such an environment is typically encountered by a turbine engine (10) of a helicopter, or off-road vehicle. The particle separator (40) provides dust and particulate control features including aero-inertial, particle trajectory, particle boundary-rebound, and scavenge flow tailoring to achieve a dust and particulates separation efficiency as good as or better than the best conventional axial-flow particle separators. This particle separation effectiveness is achieved in a radial inflow particle separator (40) which is smaller and lighter in weight than axial flow devices, and which packages advantageously with the essential structures of a turbine engine.

TL;DR: In this article, a heating and cooling system comprising a windmill for driving a first refrigerant compressor in parallel with a second refrigerant generator driven by an electric motor or other power means is described.
Abstract: A heating and/or cooling system comprising a windmill for driving a first refrigerant compressor in parallel with a second refrigerant compressor driven by an electric motor or other power means. The second compressor operates the system when the wind velocity is low. When the wind velocity becomes high enough, the refrigerant pressure created by the wind driven compressor, is used to automatically shut off power to the second compressor. The wind driven compressor then takes over the function of the second compressor.

TL;DR: In this paper, particle-image velocimetry (SPIV) measurements are conducted in a Low-speed Large-scale Axial Compressor (LSAC) with two CCD cameras placed at different sides of the laser light sheet and it is proved that this configuration is more suitable for the investigation in multi-stage turbomachines.

TL;DR: In this article, a thermodynamic model for open combined Brayton and inverse Brayton cycles is established considering the pressure drops of the working fluid along the flow processes and the size constraints of the real power plant using finite time thermodynamics.

TL;DR: In this paper, a motor-driven compressor is formed integrally with a compressor device for compressing refrigerant and a motor for driving the compressor device, and a plurality of cooling fins are formed on an inner surface of the wall of the refrigerant suction route.
Abstract: A motor-driven compressor is formed integrally with a compressor device for compressing refrigerant and a motor for driving the compressor device. The motor-driven compressor includes a drive circuit and a plurality of cooling fins. The drive circuit controls the operation of the motor. The drive circuit is provided on an outer surface of a wall of a refrigerant suction route. The plurality of cooling fins are formed on an inner surface of the wall of the refrigerant suction route. In such motor-driven compressors, the drive circuit may be sufficiently cooled without using cooling devices. As a result, providing cooling devices with the drive circuit in motor-driven compressors is no longer necessary.
