Abstract

The invention discloses a lobe ejection system with a high infrared stealth characteristic. The lobe ejection system comprises a double-layer lobe ejector, an air film cooling device and a spray cooling device. The lobe ejector is connected with an exhaust outlet of a power device and composed of an inner wall face and an outer wall face, the inner wall face is completely closed, through holes are formed in wave crests of the outer wall face, the inner wall face and the outer wall face are connected through a head gasket and a tail gasket, the head gasket is provided with through holes used for exhausting airflow and spraying mist, and a nozzle is installed on the tail gasket. The nozzle comprises an inflation connector and a water spraying connector. The air film cooling device is used for inflating the cavity, and the spray cooling device is used for spraying mist into the cavity. The inner lobe can be cooled, flue gas can be secondarily cooled at the same time, vibration of the lobe ejector in the operation process can be weakened through the double-layer structure, and the stability of the device is improved. The temperature of the wall face of the exhaust pipe and the temperature of the smoke are reduced, meanwhile, the high temperature brought by the smoke to the ejector body is reduced, and the infrared stealth performance and the survivability of a ship can be improved.

Description

technical field [0001] The invention relates to an exhaust ejection system of a ship power system, in particular to an ejection system capable of avoiding the infrared radiation increase of the ejector body while realizing the ejector's function of reducing infrared radiation. Background technique [0002] Ships are the main tool for maritime combat. Good stealth can reduce the probability of ships being accurately positioned and attacked, and improve the ship's protection capabilities and combat efficiency. The detection methods of ships mainly include radar, sonar and infrared detection, and corresponding ship stealth technologies have emerged, such as radar stealth, acoustic stealth and infrared stealth technology. Among them, infrared stealth technology is mainly used to deal with infrared-guided anti-ship weapons, and in the infrared guidance system, the most widely used is the detector in the mid-infrared band. [0003] In a ship, the radiation signal source in the mi...
