1. A wake treatment system comprising:
a water-cooled flue gas collecting apparatus;
a wake treatment structure with the water-cooled flue gas collecting apparatus disposed in a flow path formed therein; and
a storage tank provided below the wake treatment structure,
wherein the water-cooled flue gas collecting apparatus comprises:
a gas guiding portion having a flue gas inlet at one end through which a flue gas generated from a test propulsion system enters;
a gas pipe connected to the flue gas inlet at one end to pass through the other end of the gas guiding portion at the other end and form an extension; and
a collecting portion connected to the other end of the gas pipe to collect the flue gas entering through the gas pipe from the flue gas inlet,
wherein the water-cooled flue gas collecting apparatus is disposed in the flow path adjacent to the flue gas inlet,
wherein a placement of the water-cooled flue gas collecting apparatus varies depending on a length of a flame of the test propulsion system,
wherein the size of the outer circumference of a vertical cross-section of the wake treatment structure is not constant,
wherein the outer circumference of the vertical cross-section of the wake treatment structure expands and contracts repeatedly,
wherein the flow path branches out into a plurality of paths at an expansion portion where the outer circumference of the vertical cross-section of the wake treatment structure expands,
wherein a dummy space is formed to change the flow path of the flue gas in the expansion portion inside the wake treatment structure.
