The stall zone for the single axial fan and axial fans operated in parallel are shown in the figure. [4] The Figure shows the Stall Prone Areas differently for One fan and Two fans in parallel. [4] The following can be inferred from the graph : For the Fans operated in parallel, the performance is less when compared to the individual fans.
It includes separate axial fan factors and is aimed primarily at the designer of the air moving system. AMCA Publication 202 - Troubleshooting. Part 3 of the Fan Application Manual, helps to identify and correct problems with the performance and operation of the air moving system after fan installation.
Axi-symmetric stall, more commonly known as compressor surge; or pressure surge, is a complete breakdown in compression resulting in a reversal of flow and the violent expulsion of previously compressed air out through the engine intake, due to the compressor's inability to continue working against the already-compressed air behind it.
This arrangement introduces an additional gas leakage path compared to a front-fan configuration and was a problem with this engine with higher-pressure turbine gas leaking into the fan airflow. [48] An aft-fan configuration was later used for the General Electric GE36 UDF (propfan) demonstrator of the early 1980s.
An animated simulation of an axial compressor. The static blades are the stators. An axial compressor is a gas compressor that can continuously pressurize gases. It is a rotating, airfoil-based compressor in which the gas or working fluid principally flows parallel to the axis of rotation, or axially.
The reason, she says, is because Spirit doesn’t have any Boeing 737 Max 9 planes, which she said she’s wary of after watching a 2022 Netflix documentary about crashes of two 737 MAX planes.
