Host Structures

• Class of host structure (kinematics)
• Folding Deployable
• Geodesic
• Nature (birds, bats, fish)
• Strengths
• Multi mission / Multi role
• Weaknesses
• Needs much research and analysis

10
Technology

• New technology
• Host structures
• Shape Memory alloys actuation
• Def. 50 nickel, 50 titanium
• FEA analysis of complex movements
• Control of servo aeroelastic
• wing by computer control.

11
Goals

• Going away from rigid structures
• Develop Shape memory alloys that act as actuator
  and sensor.
• Improve band width of current applications

12
Current Status

• Overview of progress
• Developed two host structures
• Proposal to Darpa and AirForce pending
• The outcome of the proposed work could
  revolutionize the future wing design concept, and
  could introduce extensive NASA flight test
  programs to evaluate the revolutional
  multiple-mission adaptable wing performance.
