| description | The invention discloses a low-flow-resistance noise reduction device for high-speed and high-temperature fuel gas emission and a using method, and relates to the field of high-temperature fuel gas noise reduction in rocket or aero-engine tests, in particular to a water spraying noise reduction system and a using method. The invention provides a low-flow-resistance noise reduction device for high-speed and high-temperature fuel gas emission and a use method, and aims to meet the requirements that in the field of noise reduction of rockets or aero-engines, the noise reduction amount is high, meanwhile, water cannot be splashed to the engines, and thermal protection of noise reduction equipment needs to be in place. The method is ingenious in design and simple to operate, so that common technicians in the field can easily master the using method of the method only through the described specific implementation mode or attached drawings on the premise of not paying creative labor.
