Is EXH Intake or Exhaust?

[Arianna]

EXH stands for exhaust port. Intake port: An intake port is an opening in an air duct or similar structure that collects air by utilizing the forward motion of an aircraft and directs it into the engine or ventilator. The Mach number at the compressor inlet of a turbojet engine is approximately 0.4, with strict limitations on flow field non-uniformity. During flight, the intake duct decelerates and pressurizes the high-speed airflow, converting the kinetic energy of the airflow into pressure energy. As flight speed increases, the pressurization effect of the intake duct becomes more significant. During supersonic flight, this pressurization effect can far exceed that of the compressor, making the supersonic aircraft intake duct crucial for enhancing flight performance. Exhaust port: An exhaust port (vent) is a metrology term published in 2015. It refers to the outlet for expelling internal gases when injecting liquid into a vector device.
