WHAT IS STEALTH TECHNOLOGY

Stealth is a technique in which we can make any object invisible.

Stealth is an important technology which used in military operations.

Stealth technology also known as LO technology (low observable technology)

HISTORY

The first true "stealth" aircraft may have been developed in Germany during the last years of WWII.

This technique has also been used in ships as we can see in the figure.

WHERE IS THE STEALTH-TECHNOLOGY ALREADY USED?

B-2 BOMBER

STEALTH-TECHNOLOGY„How does it works...“

HOW TO MAKE THINGS INVISIBLE?

BUT HOW COULD IT WORKS, THAT MARTIN IS ABLE TO SEE KATJA ?

HOW COULD THE LIGHT BE DEFLECTED?

Refractive Index

Optical Materials

Metamaterials

FACTORS OF STEALTH TECHNOLOGY

  The object can be shaped so that any radar signals it reflects are reflected away from the radar equipment.

The object can be covered in materials that absorb radar signals.

SHAPE OF ANY OBJECT

When we are using normal shape

While we use Stealth Technology

AWCT (ADOPTIVE WATER CURTAIN TECHNOLOGY)

This technology is a part of stealth which is used in the ships for making low observable.

WHAT IS RADAR ABSORBING MATERIALS (STEALTH)?

Nanostructural composite material, absorbing without reflection radar wave.

This new material is basedon nanotechnology.

MATERIALS

Carbon fiber compositesMagnetic ferrite-based substance

RAM reduces the radar cross section making the object appear smaller.

DETECTION OF STEALTH TECHNOLGY

Reflected waves

Infrared (Heat)

Longer wavelength radar

OTH radar

ADVANTAGES OF STEALTH TECHNOLOGY

Reduce the causality rate during the war.

Saving military budget.

Develop the military secretes.

Bluff the anti-detective device.

DISADVANTAGES OF STEALTH TECHNOLOGY

Instability of design

Electromagnetic emissions

Cost of maintenance

Sensitive skin

Cost of operations

APPLICATION OF STEALTH TECHNOLOGY

Military Operation

Civil Aviation ( In Future by Boeing)

In Spacecraft

In Launch Vehicles
