The slightly curved, near vertical, lines on the main part of the map are the (constant rotational) corrected speed lines. ... The IP compressor outlet corrected flow must match the entry corrected flow of the HP compressor, which is decreasing … See more A compressor map is a chart which shows the performance of a turbomachinery compressor. This type of compressor is used in gas turbine engines, for supercharging reciprocating engines and for industrial … See more A compressor map shows the operating range of a compressor and how well it works within its operating range. Two fundamental requirements for the gas flowing through a compressor explain why it works best at a design condition and not so well at other … See more Flow axis The x-axis is usually some function of compressor entry mass flow, usually corrected flow or non-dimensional flow, as opposed to real … See more Some turbofans have an intermediate pressure (IP) compressor located between the fan and the high pressure (HP) compressor to increase overall pressure ratio. US civil … See more Compressors pump gas for a wide variety of applications each of which has its own flow resistance which the compressor has to meet to keep the gas flowing. A map shows the pumping … See more Different applications move over their particular map along different paths. An example map with no operating lines is shown as a pictorial reference with the stall/surge line on … See more A low pressure ratio fan (such as that used on a high bypass ratio turbofan) has a range of working lines. At high flight speeds, the ram pressure ratio factors up the cold nozzle … See more the future of anime
