Abstract
The invention discloses a method for preventing an object from being tracked by an infrared guided missile. A liquid nitrogen storage tank is arranged in the object, and a liquid nitrogen ejecting opening of the liquid nitrogen storage tank faces an infrared heat source position on the surface of the object. The method is used for quick cooling of high-temperature airflow ejected by an airplane, a tank, a steamship, an automobile and positions which easily generate high temperature, reduces external radiation of infrared rays so that the purpose of preventing tracking of the infrared guided missile is realized.
Description
Technical field
The present invention relates to a kind of method that prevents that object from being followed the trail of by the infrared ray guided missile.
Background technology
The infrared ray that object radiation goes out is the target-seeking approach of modern war middle infrared (Mid-IR) missile target, and a lot of aircrafts and car and boat etc. all are destroyed in the hand of infrared ray guided missile.Attack for fear of the infrared ray guided missile, improve one's own side's survival ability, people have developed the method for various anti-infrared ray guided missiles one after another, such as: 1, the exhaust flange pass is penetrated hybrid technology: inject cold air during aircrafts exhaust and mix the purpose that reaches cooling, water down gas concentration lwevel, reduce the gas radiation rate.2, closed-loop path cooling system: SR-71 blackbird aircraft just adopts the closed-loop path cooling system, and the heat of fuselage is passed to fuel oil, or heat is dissipated under the frequency that atmosphere can not fully conduct.3, jet pipe one blocks technology: refer to utilize rear body, vertical fin etc. that jet pipe inner chamber and wake flame core are effectively blocked, can obtain good infrared inhibition.4, two-dimensional nozzle technology: the two-dimensional nozzle that adopts low-infrared radiation, be conducive to improve the mixing structure of wake flame and atmosphere, F-117A adopts the two-dimensional nozzle of aspect ratio (high 15 centimetres, wide 1.83 meters), greatly improve the cooling rate of wake flame, shortened the wake flame core length.5, infrared flare: this ammunition is by the powerful infrared energy of radiation; make a source of infrared radiation identical with claimed target; inveigle enemy's infrared guidance guided missile to have dust thrown into the eyes and mainly tackle the infrared homing guided missile of enemy omnidirectional and Dual band IR seeker, belong to active cheating formula IR decoy.Other also have firework type IR decoy, compound IR decoy and fuel type IR decoy.However, still there is infrared ray to be caught in, brings opportunity to having the target-seeking fly bomb of highly sensitive infrared ray.
Summary of the invention
The object of the present invention is to provide a kind of method that prevents that object from being followed the trail of by the infrared ray guided missile, it is simple, can reduce quickly and effectively the body surface infrared emanation, thoroughly eliminates by the possibility of infrared ray guided missile pursuit attack.
The object of the present invention is achieved like this: a kind of method that prevents that object from being followed the trail of by the infrared ray guided missile, liquid nitrogen storage tank is installed in object, and the liquid nitrogen spray mouth of liquid nitrogen storage tank is towards the infrared heat source position of body surface.
The inventive method is on the basis of existing infrared countermeasure set, the position that aircraft or tank are easily produced high temperature, as: the afterburning storehouse of aeroengine afterbody, head and wing etc. easily locate to install additional the liquid nitrogen spray device with the position of windage generation high temperature, tank engine, blast pipe etc.When finding that infra-red missile is followed the trail of, or when being about to come into action state, start the liquid nitrogen injection apparatus and spray a certain amount of liquid nitrogen its high-temperature infrared source and surrounding air are cooled off rapidly, to reach the reduction infra-red radiation, reduce by infra-red missile follow the trail of may.Under the condition that equipment allows, the keypoint part stronger to infra-red radiation sprays more, and an amount of liquid nitrogen is sprayed at all the other positions, to arrive the whole cooling of equipment, reduces the whole externally purpose of infra-red radiation of equipment.
The inventive method is simple, can reduce quickly and effectively the body surface infrared emanation, thoroughly eliminates by the possibility of infrared ray guided missile pursuit attack, improves the infrared stealthy ability of weaponry and the survival ability on the battlefield.
The specific embodiment
A kind of method that prevents that object from being followed the trail of by the infrared ray guided missile is installed with liquid nitrogen storage tank in object, the liquid nitrogen spray mouth of liquid nitrogen storage tank is towards the infrared heat source position of body surface.The high temperature gas flow that the inventive method is sprayed aircraft, tank, steamer, automobile with liquid nitrogen and easily produce high temperature position and cool off rapidly, reduces ultrared to external radiation, to reach the purpose of prevention infra-red missile tracking.Said infrared heat source position is exhaust pipe mouth, enging cabin surface and the wing edge of a wing of object.The external infra-red radiation of the reinforcement equipment that the inventive method is all right artificial, when finding that infra-red missile is followed the trail of (when coming into action state), close strengthen external infrared radiation device, simultaneously start the liquid nitrogen injection apparatus, change the movement locus of equipment, the purpose that reduces the intensity of the external infra-red radiation of equipment and feature, the identification of realization deception infra-red missile, follows the trail of to reach amplitude peak.
Claims (2)
1. method that prevents that object from being followed the trail of by the infrared ray guided missile, it is characterized in that: liquid nitrogen storage tank is installed in object, and the liquid nitrogen spray mouth of liquid nitrogen storage tank is towards the infrared heat source position of body surface.
2. the method that prevents that object from being followed the trail of by the infrared ray guided missile according to claim 1, it is characterized in that: said infrared heat source position is exhaust pipe mouth, enging cabin surface and the wing edge of a wing of object.
