Aerospace Engineering Smart Material Solutions
  • Smart Tabs
    Shape Memory Alloy (SMA) actuated tabs that allow tuning of rotor blade aerodynamics in-flight for tracking, survivability, performance enhancement and noise reduction - read more...

  • BVI Noise Mitigation Using SMA-Driven Flaps
    Using our CHARM/WOPWOP analysis, CDI engineers identified an on-board flap system that can be deployed during landing to reduce BVI noise by a factor of two. This prediction was then validated through wind tunnel testing in the Ames Research Center 7' x 10' Wind Tunnel - view a poster of this project...

  • Deployable "Pop Up Vortex Generator" (PUVGs)
    SMA-based actuators used to deploy Pop Up Vortex Generator (PUVG) devices on aerodynamic surfaces - read more...

  • High Temperature SMA Actuators
    Aeropropulsion applications - read more...

  • Variable Twist Rotor Blade Design
    Using CDI's rotorcraft analyhsis software and SMA-actuator expertise, CDI has designed Variable Twist Tilt Rotor (VTTR) blades that can be modified in flight to improve hover and cruise performance as well as reduce BVI noise during landing - view a poster of this project...
