Abstract

The invention discloses an infrared generator specially used for an infrared target and belongs to the field of aero-engines, and the infrared generator is used for solving the problems that the traditional infrared target adopts a method of explosive detonation to obtain infrared, thus the efficiency of target practice is low, and no high-level infrared target exists in China. The infrared generator is composed of a miniature turbojet engine, a combustion-supporting device and an infrared generating chamber, and the principle of the infrared generator is as follows: the miniature turbojet engine is used as a thermal power, the gas discharged by the engine is ignited once again by oil injection of the combustion-supporting device, and further burns in the infrared generating chamber, so that the temperature of a shell of the infrared generating chamber is higher, and thus the high-intensity infrared is generated on the surface. The infrared generator disclosed by the invention can be used for overcoming the defect that the infrared is obtained by explosive detonation, and because fuel oil and combustion mode and the like of the infrared generator are same to a military plan, the characteristics of the generated infrared are closer to the reality, and the biofidelity is higher.

Description

Infrared generator

Technical field

The invention belongs to the aeroengine field

Background technique

With the purpose of infrared rays target be exactly the Friendly Aircraft Simulating Aggressors jet pipe due to the infrared rays that high temperature produces, the guided missile that is provided with infrared guidance carries out gunnery training.The critical component of infrared rays target is exactly infrared generator, the high temperature that the infrared rays of China's infrared rays target substantially all utilizes the explosive detonation to produce at present obtains, because the explosive inflammation time is shorter, and disposable use, so produce the ultrared time, be also limited, cause sometimes opportunity of combat also not aim at target explosive finishing combustion, now target again can not produce infrared rays, will affect training effect and benefit like this.

Summary of the invention

In order to address the above problem, I have invented a kind ofly take miniature turbine jet engines as heat power, through secondary combustion, produces the ultrared infrared generator of high strength.This infrared generator is comprised of miniature turbine jet engines, blower and infrared rays generation chamber.Cancel the jet pipe of miniature turbine jet engines, blower directly is fixed on to the exhaust end of miniature turbine jet engines, the infrared rays generation chamber is fixed on blower; The high temperature produced when motor, at a high speed, pressurized gas are while flowing through blower, through oil jetting combustion again, make the gas that temperature is higher arrive infrared rays generation chamber (temperature herein can reach 1400 ℃ of left and right), will make like this its surface emissivity go out very strong infrared rays, thereby reach, obtain ultrared purpose.According to Preliminary Determination wavelength 3-6 η, maximum strength is 360w/s, and this level can meet the target practice training requirement fully.

Embodiment

The working principle of infrared generator: at first start miniature turbine jet engines, when its exhaust reaches uniform temperature, spray into the exhaust of fuel oil ignition engine through blower, further burning again in the infrared rays generation chamber, make infrared rays generation chamber case temperature higher, and make its outer surface width penetrate stronger infrared rays.

Advantage of the present invention: the first longevity of service and reusable aloft.As long as prepare enough just can be the according to plan omnidistance work of oil plant, stopped working and can also repeat to light, like this with regard to overcome explosive due to the detonation time the short and disposable problem that affects training effect; The second volume is little, lightweight, simple in structure; About this infrared generator maximum diameter 160mm, long 410mm, containing oil plant gross weight 2.43Kg; The 3rd infra-red intensity can be regulated as required.Certain situation at the secondary fuel delivery, utilize the rotating speed of motor can regulate ultrared radiation intensity, also can utilize the engine oil amount of simultaneously regulating (to claim fuel feeding one time, or once light a fire) and blower fuel delivery (title secondary fuel feeding, or regnition), regulate ultrared radiation intensity.Thereby changed the present situation that an explosive detonation can only a kind of infra-red intensity, made the Applicable scope of target wider.The fuel oil of the 4th infrared generator use is the same with the fuel oil of aircraft utilization, and too, this infrared rays feature that will make both produce is also substantially the same for combustion manner.Therefore, make target emulation degree with this infrared generator higher.

Claims

1. this infrared generator consists of miniature turbine jet engines, blower and infrared rays generation chamber, as heat power with miniature turbine jet engines, through the blower oil spout gas that ignition engine is discharged again, make its further burning in the infrared rays generation chamber, and cause infrared rays generation chamber case temperature higher, thereby produce stronger infrared rays; The major character of infrared generator is to burn to obtain infrared rays with aircraft fuel oil, and time of origin is long and reusable, the emulation degree is high, volume is little, lightweight, simple in structure.
