2What 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.
3PIEZO ELECTRIC EFFECT
- Mechanical stress Electric current
4Smart Flap Control
SMART flaps responding to electrical signals.
5- Advantages
- Weight reduction
- Low cost
- Low maintenance
- Increased fuel efficiency
- Does not require hydraulic systems
- Bending to desired level
6Changing Wing profile
- Used during take off landing
- Reduces the Weight, Drag and also the co2
emissions.

Adaptations
- Light Visionary Model
- Flexible Polyurethane coated spandex fabric body
9SMART 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
10- 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
11MORPH 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
