Stealth Technology Seminar PPT with PDF Report

Radar Absorbing Materials (RAM)

  • RAMs often as paints used to absorb RADAR signals.
  • Iron ball paint, ferrite in polymer matrix used.
  • Small cell foams painted or loaded with absorbing ink.
  • R- Card
  • Absorbing honeycomb
  • Transparent RAM

Other fields

  • Reducing RCS alone not enough.
  • More difficulty is reducing the IR signature.
  • Interest is near IR region. (shorter than 10 µm)

IR Emission

Major IR emission sources.

  • Tailpipe region
  • Turbojets have EGT’s of 1000oC
  • Exhaust gas plume
  • Hot engine parts
  • Aircraft skin (frictional heating)
  • Reflected and reemitted sunlight.

IR Reduction

  • Using surface paints
  • Non circular tail pipe
  • Emissions from hot parts screened by airframe.
  • The plume mixed with cool air.
  • IR best transmitted 2.5, 4 and 10 micron bands.
  • IR outside window absorbed by CO2
  • Passive IR target acquisition systems more used.

 Electromagnetic emissions

  • EM emissions other than IR .
  • The greatest source is RADAR itself.
  • Shutting down RADAR a solution having negative effects.
  • Radio /radar altimeters and Doppler navigation systems.


  • Stealth technology developed a lot.
  • Investment needed is very high.
  • High chance of low cost gain.
  • A lot learned about signature reduction and absorption.
  • Useful for other projects.
  • Success yet to be proved extensively.
