Abstract

The invisible flight vehicle is characterized by that it makes the outer shell of said vehicle carry positive charge to produce a constant electric field to make radar wave deviate and cann't be reflected back, and at the same time said outer shell is coated with semiconductor layer to absorb electromagnetic wave, and its tail gas exhaust is equipped with a tail gas cover to tower its temp. and block off diffusion of tail gas infrared rays so as to avoid the tracing of radar and infrared detector and attain the goal of stealth flying.

Description

Concealed aircraft

The present invention relates to a kind of flying instrument of weapons, particularly stealth aircraft, stealthy guided missile.

At present, China existing aircraft all can not be accomplished stealth as aircraft, guided missile, promptly can be with aircraft or guided missile location once the electromagnetic wave of the radar emission of taking off, because jet engine tail gas is high-temperature gas, infrared detector can also detect the flight path of aircraft again.It is reported that there is stealth aircraft in the U.S., but do not obtain the data of its principle of play-by-play.

Purpose of the present invention is exactly to solve above-mentioned deficiency, applies steady electric field and provide a kind of at the aircraft outside face, and coating quartz conductor protective layer absorbs electromagnetic wave, and the tailing gas hood reduces exhaust temperature, reaches stealthy.

The solution that realizes the object of the invention is that direct supply 1 is set on aircraft, and is connected on the shell 9 by lead 3, makes aircraft skin 9 positively chargeds; Simultaneously, at shell 9 outside faces coating quartz conductor protective layer, absorb electromagnetic wave; Tail gas cover 6 is set for the aircraft fumarole outward.

The direct supply 1 that is provided with on aircraft is dynamo generator, amplidyne, direct current voltage multiplier.The shape of tail gas cover 6 be one dolioform, tiny in the middle of promptly, two is horn-like amplification.Between tail gas cover 6 and the aircraft fumarole certain interval is arranged, so that enter cold air, cooled exhaust gas.

Advantage of the present invention is to make the enemy radar ripple produce deflection, absorption, reduces the angle of visibility of infrared detector, reaches the purpose of stealthy flight.

The present invention is described in further detail below in conjunction with accompanying drawing:

Fig. 1 is an aircraft skin positively charged scheme drawing;

Fig. 2 is the electromagnetic wave superposition scheme drawing of Fig. 1;

Fig. 3 is a not tailing gas hood scheme drawing of aircraft;

Fig. 4 is an aircraft tailing gas hood scheme drawing.

Direct supply 1 is set in aircraft, and direct supply 1 can be dynamo generator, amplidyne or direct current voltage multiplier, and when the effect of switch 2 was connection, vdc was added on the aircraft skin 9 by lead 3, makes shell 9 band "+" electric charges, produces steady electric field E ₁, this moment is if having radar wave along X ₁Direction penetrates, the electric field component E of radar electromagnetic wave ₂Will with steady electric field E ₁Superposition synthesizes E by parallelogram law ₃When radar electromagnetic wave is run into aircraft metal case 9, magnetic-field component H can produce eddy field in metal case 9, according to the big equation dirH=0 of Mike Si (divergence in magnetic field be zero) and rotE==-1/c H/ t (curl of electric field E equal magnetic field to the rate of change of time divided by luminosity C, negative sign is shown reactive).Can draw radar electromagnetic wave from X ₁Direction is injected, along X ₂Direction penetrates, radar wave deflection.When not needing stealthy flight, switch 2 disconnects, and aircraft skin 9 is not with "+" electric charge, can use radar navigation.

There is the non-uniform electric field place at indivedual positions, aircraft skin 9 surfaces, still have reflection,a few to produce, and aircraft surface is applied protective layer, and protective layer is made quartz conductor, can absorb electromagnetic wave.Its principle is: when electromagnetic wave was run into metal on working direction, the degree of depth that penetrates metal inside was penetrance, and the metallo-electric conductivity is good more, and penetrance is more little, otherwise penetrated deeply more, and electromagnetic wave can pass insulator; The quartz conductor forward resistance is little, be conductor, back resistance is big, is insulator, the aircraft surface protective layer is made semiconductor layer, when electromagnetic wave directive aircraft,, can penetrate protective layer for oppositely entering, when running into metal case 9 reflex times, protective layer is that forward passes through, and protective layer is electric conductivity and stops electromagnetic wave to penetrate, and protective layer shows as the absorption electromagnetic wave.

Protective layer is made black, absorbs infrared light, prevents infrared acquisition.

Once taking off, infrared detecting set just may detect the angle of visibility 10 that aircraft jet engine discharging high-temperature tail gas 5, infrared detecting set can detect aircraft exhausr port mid point 8 greater than 180 ° of aircraft.After aircraft afterbody air nozzle added tail gas cover 6, the angle of visibility 10 of the angle of visibility 11 that exhaust port mid point 8 is detected by infrared detecting set during than anury gas hood 6 was much smaller.Reduced tested probability, the infrared acquisition of ground station and satellite all can not detect aircraft.

The length 7 that changes tail gas cover 6 can be controlled the size of angle of visibility 11, tail gas cover 6 is done an exit skirt, with the aircraft air nozzle gap is being arranged vertically, the air-flow 2 of aircraft skin 9 is from the exit skirt gap location, pressure enters in the tail gas cover 6, make the drop in temperature of exhaust port mid point 8, reduce ultrared distributing.
