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

STAGES OF DEVELOPMENTS

Parker Variable Camber WingsLIG-7

ICE-Aircraft

Boeing Dragonfly

UAV

Virginia Tech BetaMax

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

NASTIC STRUCTURE

Nastic Tensile test at 20 psig

Nastic Tensile test at 50 psig

Nastic Tensile test at 100 psig

Bump flattening Trailing Edge Deflection

CURRENT RESEARCHAdvancements in smart materials

NASA’s 6 year Aircraft Morphing Program

Researches in Lockheed Martins & Boeing

COMPARISON BETWEEN CONVENTIONAL WING AND

MORPHING WING STRUCTURES

Before morphing

After morphing

APPLICATIONS

F-14 AV8-B Harrier

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

FUTURE SCOPE

Vertical take off & landing

Development of “ as-light-as air” system

Improvement in uplift using tilt wings & with rotors.

Short take off & landing
