The document discusses stealth technology, which reduces detection of aircraft using techniques like shaping the vehicle to deflect radar waves, embedding radar absorbing materials, and burying engines within wings. It provides details on the history of stealth beginning in Germany in WWII and its use in ships. Radar and infrared detection are also explained. The document outlines stealth techniques for aircraft including injecting ionized gas plumes and covering engines, as well as benefits like reduced casualties and military budget savings. Future applications and challenges of stealth technology are considered.

Stealth Technology
Scientifically know as
LOW OBSERVATORY.
Used in military aviation
Reduces detection range
of an air craft Similar to camouflage tactics
used by soldiers
Partial indivisibility to radar
and other detection

The first “STEALTH” aircraft
have been developed in Germany
during the last years of WWII.
This technique has also been used
in ships.
Later Americans worked on
stealth technology and succeeded.

longer wavelengths than those
of visible light.
frequency range approximately
430 THz down to 300 GHz.
 thermal radiation emitted by
objects near room temperature is
detected.

Almost since the invention of radar, various techniques have
been tried to minimize detection
Some of the techniques used for this purpose are:
1.Vehicle shape
2.Radar absorbing material

Radar absorbing materials
Acute angle
Design of NOSE
Stealth air craft must bury the
engines within the wings
