What is “MORPHING”?
INTRODUCTION
Structural Adaptability
Morphing
wings
Multidisciplinary optimization
Aerodynamic
adaptability
Multirole vehicle
Adaptive wings
BACKGROUND
Performance versatility in an Eagle’s wings
Origin of Idea
Active wing transformation
WING DESIGN
Morphing wing prototype
Wing twist
NEW WING DESIGN TECHNOLOGIES
Active wings: Wing warping
Senses air flow
Reduces fuel burn
Modifies for optimum efficiency
Uses articulating winglets
Reduces drag
Distributes aerodynamic loading & improve lift at l0w speeds
SMART WINGS
TechniquesUse of “intelligent” materials
Piezoelectric/Piezo-ceramic PneumaticElectro-Active Polymer Shape Memory Alloy Piezoelectric MotorElectromagnetsElectric Motor Hydraulic Shape Memory Polymer
Trailing Edge Deflection
COMPARISON BETWEEN CONVENTIONAL WING AND
MORPHING WING STRUCTURES

APPLICATIONS
F-14 AV8-B Harrier
FUTURE SCOPEVertical take off &
landing
Development of “ as-light-as air” system
Improvement in uplift using tilt wings & with rotors.
Short take off & landing
CONCLUSION Revolutionary improvements in efficiency,
safety of flight vehicles
Significant improvement in fatigue-life
Reduction in weight of load –carrying components
Improvement in high lift system
