In this i focused only the aircraft for the invisibility because in present time in defense the stealth technology is the big need............ it has totally scientific content................. thank'U your suggestion will be highly obliged. sunil kumar niranjan inderaprastha engineering college ghaziabad snsweetsunil@gmail.com Comments Posting comment... By: abhaymaurya (9 month(s) ago) wonderful presentation ever seen.........sir please allow me ti download this presentation.......please give me your cell no................i m highly impressed by ur way of thinking............other should take lesson from u ..........every presenter should be once watch this presentation........... my email id -amaurya0258@gmail.com Saving.....

Niranjan B.Tech , ECE, 6 th sem 0803031087 IPEC, GZBINTRODUCTION: INTRODUCTION Stealth is a technique in which we try to make any object invisible. Stealth technology also known as LO technology (low observable technology). It is a sub-discipline of military tactics and passive electronics countermeasures.HISTORY: HISTORY Primarily me make the object visually invisible in stealth technology. After the invention of radar other method used in stealth technology. The first true "stealth" aircraft may have been developed in Germany during the last years of WWII.Goal of Stealth Technology: Goal of Stealth Technology To make aircraft invisible by reducing radar, IR, visual, and acoustic signature.Principle of Stealth Technology : Principle of Stealth Technology Infrared detection. Visual detection. Acoustic detection. Radar detection. Reduction in these detection is the principle of stealth technology.Reduction of Infrared Emission: Reduction of Infrared Emission IF emission is occur due to heat. All substances with a temperature above absolute zero (0° K, or -273.15° C, or - 459.67° F), emit electromagnetic waves. The heat content of a material produces molecular vibrations which cause electron oscillations. These oscillations provide electromagnetic coupling that produces an emission of energy. …………….Slide 7: ……continued Method to decrease the IR signature of the engines is to use exhaust masking. This is accomplished by placing the engines on top of the body and the wings, by which exhausts cannot be seen from below.Reduction in Acoustic Detection: Reduction in Acoustic Detection In this we reduce mechanical noise. For reduction of mechanical noise we use different muffler, slow turning propeller. Submarines use extensive rubber mountings to isolate and avoid mechanical noises that could reveal locations to underwater passive sonar arrays .Deceiving of Eye: Deceiving of Eye In this method we make the object visually invisible. In this we use different color and different lightning system, by which system generate illusion.Reduction in Radar Detection: Reduction in Radar Detection Radar mainly work on electromagnetic wave reflection. If we avoid these reflection towards the radar receiver than we can reduce radar cross section of object. Radar cross section (RCS) is a measure of how detectable a object object is with a radar.RCS Reduction Technique (Reduction in Radar Detection) : RCS Reduction Technique (Reduction in Radar Detection) Purpose shaping : The shape of the target’s reflecting surfaces is designed such that they reflect energy away from the source. Radar absorbent material : As an addition to highly reflective surfaces. Active Cancellation : Target generates a radar signal equal in intensity but opposite in phase to the predicted reflection of an incident radar signalPurpose Shaping: Purpose Shaping Normal design Curved designRadar Absorbing Material: Radar Absorbing Material RAM material absorb EM wave and convert this energy into heat. Some RAM material have active cancellation also. RAM material are iron ball paint, foam absorber etc.Active Cancellation: Active Cancellation In this method we have some RF source on object(plane, ship) which modify radar signal but in opposite phase that generate destructive interference. Thus by the use of these three method we can reduce RCS of our plane and can make them low observable.Advantage : Advantage Reduce the causality rate during the war. Develop the military secretes. Bluff the anti-detective device . We can perform spy mission.Disadvantage : Disadvantage Instability of design. Cost of maintenance. Sensitive skin. Cost of operations.“Some Stealth Aircraft”: “Some Stealth Aircraft”Slide 18: B-2 BomberSlide 19: F-22 RaptorReferences: References “Naval Post Graduate School, California” thesis on stealth technology. Wikipedia. British encyclopedia. Google images on stealth technology. “THANK YOU”: “THANK YOU” QUERIES?: QUERIES? You do not have the permission to view this presentation.
