The most important tactic in today's warfare is the Element Of Surprise which u give to the enemy and the f-22 provides it to the last ounce ............stealth..The stealth of the F-22 is due to a combination of factors, including the overall shape of the aircraft, the use of radar absorbent material (RAM), and attention to detail such as hinges and pilot helmets that could provide a radar return.[153] However, reduced radar cross section is only one of five facets that designers addressed to create a stealth design in the F-22. The F-22 has also been designed to disguise its infrared emissions to make it harder to detect by infrared homing ("heat seeking") surface-to-air or air-to-air missiles, including its flat (rather than round) thrust vectoring nozzles.[154] Designers also made the aircraft less visible to the naked eye, and controlled radio and noise emissions.[153] The Raptor has an under bay carrier made for hiding heat from missile threats, like surface-to-air missiles.[155].................................Too much i guess....thats all for now and keep commenting om my posts so that i can make them better and better.Yess the most expected aircraft post on my blog is here particularly keeping the design in perspective...I wont go into the technical details where u 'll find everywhere else but give you an insight to what an airplane like the f-22 actually means to aviation designing............lets go back to the time around WW2 when the radar was first invented.It was supposed to be "The" machine the defence forces would fancy, having it.It was used mainly for keeping a strict vigil on the airspace of a whopping area of about 400 km in all directions.You could know about attacks about 2 hours ago and the list keeps on going.About 1.5 decades ago the idea of an "radar invisible" aircraft was thought of .It seemed as an arguably impossible idea as u could not build the plane out of fluids which wouls absorb the radiation instead of reflecting it back, but no one thought of it this way ie.. deflecting away the radiations . Then the engineers at Lockheed Martin came up with a combination of factors such as radar-absorbent material-coated S-shaped intake ducts that shield the compressor fan from reflecting radar waves, the F-22 design placed a much higher degree of importance on low observance throughout the entire spectrum of sensors including radar signature, visual, infrared, acoustic, and radio frequency.

hey i have a question....
ReplyDeletehow exactly does a bird that propels
itself by hot burnt gases reduce its infrared emissions???
