Where are the water washes located?

• A. Gear box side of the inlet air plane
• B. Inlet plenum
• C. Nacelle area
• D. Tail section

Answer: (A)

Water wash ports are located in the inlet plenum, with spray nozzles in the duct ahead of the compressor to deliver wash water into the incoming air stream. Placing the wash nozzles here ensures the water mixes with air and passes through all compressor stages, effectively cleaning the blades and deposits. Positions like the gear box side of the inlet, the nacelle area, or the tail section aren’t used for wash delivery because they don’t place the water in the correct part of the air path or protect sensitive components; the inlet plenum is the proper location to achieve an even, effective wash of the compressor.
