What are SMART materials how smart are they???
SMART MATERIAL RESPONDING TO CHANGE IN
TEMPERATURE.
The MR fluid is liquid as shown on the left, when
no magenetic field is present, but turns solid
immediately after being placed in a magnetic
field on the right.

PIEZO ELECTRIC EFFECT

• Mechanical stress Electric current

Smart Flap Control
SMART flaps responding to electrical signals.

• Advantages
• Weight reduction
• Low cost
• Low maintenance
• Increased fuel efficiency
• Does not require hydraulic systems
• Bending to desired level

6
Changing Wing profile

• Used during take off landing
• Reduces the Weight, Drag and also the co2
  emissions.

SMART VORTEX GENERATOR

• Mixes high energy air in the free stream with
  the low energy air in the boundary layer
• Prevents stalling by re-energising the boundary
  layer
• Increases the streamwise momentum

• OPERATION
• The higher energy fluid is more resistant to
  separation and allows higher performace of the
  aircraft
• Vortex generators are simply small plates that
  just jut above the wing surface
• They look like tiny little wings jutting up
  perpendicular to the wing itself
• As air moves past them vortices are created of
  the tips of the generators just like trailing
  vortices created by the wing to speed it up and
  help reduce the possibility of separation

MORPH CONCEPT

• Morph in greek means change in shape
• But here we use this term for flexible
  electronics

A cell phone which is morphed into a wrist watch
