презентация к уроку по английскому языку (8, 9, 10, 11 класс) на тему

Слайд 1

Слайд 2

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

Слайд 3

History: 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.

Слайд 4

Electromagnetic radiation with 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. Infrared radiation

Слайд 5

What Is RADAR ? Radar is abbreviated as radio detection and ranging. Radar was developed for war application , now its applications had diversified . This is used to launch the missiles based on the target and also counter attack the missiles launched by other countries.

Слайд 6

RADAR CROSS-SECTION REDUCTIONS 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

Слайд 7

STEALTH VECHICLE SHAPES & DESIGN Rad ar absorbing materials Acute angle Design of NOSE Stealth air craft must bury the engines within the wings

Слайд 8

A corner reflector is a retro reflector consisting of three mutually perpendicular, intersecting flat surfaces, which reflects electromagnetic waves back towards the source

Слайд 9

Difference between conventional & stealth aircraft design

Слайд 10

Normal fighter plane showing the engine Engines of the aircraft are covered

Слайд 11

Nanostructural composite material, absorbing without reflection radar wave. What is Radar Absorbing material ( stealth)? Magnetic ferrite-based substance RAM reduces the radar cross selection making the object appear smaller.

Слайд 12

Advantages: Reduces the causality rates during war Saving military budget. Develop the military secretes Bluff the anti-detective device Stealth aircraft are invisible to radar

Слайд 13

Disadvantages : Stealth aircraft cannot fly fast. It is not maneuverable. S tealth aircraft can carry reduced amount of payload. Cost of maintenance. Very economic. Does not provide the optimum amount of lift .

Слайд 14

Development in the field of defense Most countries are investing heavily in them and the emerging technologies. Stealth Technology has improved significantly more advanced. S tealth technology are not yet available worldwide, but military forces around the world will soon begin to attempt to mimic some of the key features of stealth planes. Future Of The S TEALTH

Слайд 15

DRK College of Engineering & Technology Technical Seminar Date Conclusion. Stealth technology developed a lot. Investment needed is very high. High chance of low cost gain. A lot learned about signature reduction and absorption. Success yet to be proved extensively. Useful for other projects.
