The interaction between gas turbines and airborne particles determines detrimental effects on the performance, efficiency, reliability of power unit. When it is possible, reduced by use inlet separators filtration systems. In an aero engine, these barriers are difficult to implement, only bigger (usually greater than 10 μm) separated from airflow. Small units, especially those equips helicopter...

Abstract The paper describes an approach for determining the technical state of axial compressor as part a gas turbine unit, based on thermogasdynamic parameters that are measured at operating facility. As criterion condition, it is proposed to use ratio actual efficiency reference in such modes. To do this, enough know temperatures and pressures air inlet outlet compressor. A method selecting ...

Axial flow compressors are subjected to demands for ever-increasing levels of pressure ratio at a compression efficiency that augments the overall cycle efficiency. However, unstable flow may develop in the compressor, which can lead to a stall or surge and subsequently to gas turbine failure resulting in significant downtime and cost to repair. To protect against these potential aerodynamic in...

The scroll compressor incorporates new construction concepts and is quite different from other types of compressor. This unique and simple compression mechanism has a number of advantages such as small size, light weight, high efficiency, long life, and quiet operation. The compliant mechanism is one of the key ways to improve the performance and reliability of scroll compressors. The concept o...
