Modular multi-channel particle separator

摘要

A modular multi-channel particle separator is provided to block foreign objects from entering the inlet of a gas turbine engine and to remove particulate matter from the inlet air stream before it reaches the compressor section of the engine. Each module is designed for easy fabrication from sheet material which can be readily configured to remove both fine and coarse particles from the air stream with minimal pressure loss, system volume and weight. Each module also defines passages for removing particular matter that has been intercepted and for conducting heating air through the module to prevent icing. The modular construction of the separator simplifies initial assembly in the gas turbine engine, as well as later maintenance and replacement of one or more modules, should that prove necessary.
