What is “MORPHING”?

INTRODUCTION

Structural Adaptability

Page 3: morphing wings

Morphing

wings

Multidisciplinary optimization

Aerodynamic

adaptability

Multirole vehicle

Adaptive wings

Page 4: morphing wings

BACKGROUND

Performance versatility in an Eagle’s wings

Origin of Idea

Active wing transformation

Page 5: morphing wings

WING DESIGN

Page 6: morphing wings

Morphing wing prototype

Wing twist

Page 7: morphing wings

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

APPLICATIONS

F-14 AV8-B Harrier

Page 12: morphing wings

FUTURE SCOPEVertical take off &

landing

Development of “ as-light-as air” system

Improvement in uplift using tilt wings & with rotors.

Short take off & landing

Page 13: morphing wings

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
