Abstract:
A gas system for testing aircrew systems including a first system and a second system, said gas system comprising:an input filter located in an inlet port, said input filter filtering an air to prevent foreign particles from entering said gas system a first compressor compressing said air, said first compressor comprising at least one blower, a speed of said blower depending on a voltage applied to said blower; a second compressor compressing said air, said second compressor producing a lower flow at a higher pressure than said first compressor; a first flow sensor detecting a flow of the air compressed by said first compressor and a leaking of the aircrew systems; a second flow sensor detecting the flow of the air compressed by said first compressor and the leaking of the aircrew systems; a first flow valve mounted for controlling the flow of the air compressed by said first compressor to said first flow sensor; a second flow valve mounted for controlling the flow of the air compressed by said first compressor to said second flow sensor; a regulator regulating a pressure of said second system; a first pressure sensor detecting a pressure of said first system; a second pressure sensor detecting the pressure of said second system; a first pressure valve for controlling the pressure of said first system; a second pressure valve for controlling the pressure of said second system; and a controller controlling an operation of said gas system.
