INNOVATION

A non-explosive “Pinpuller and Rotary” actuator employing shape memory alloys (SMA)

  • ACCOMPLISHMENTS
  • Developed an actuating mechanism by harnessing the recovery characteristics of SMA
  • Developed a SMA trigger mechanism which allows for fast (milli-second) actuation
  • Flight qualified several embodiments prior to the end of Phase II funding
  • Patented trigger mechanism based on SMA technology
  • COMMERCIALIZATION
  • An SMA actuator was used to successfully deploy solar arrays for the Clementine Spacecraft
  • This technology expanded company’s aerospace product line sufficiently to enable them to spin off a new company called TiNi Aerospace, Inc.
  • TiNi Aerospace’s production of aerospace release mechanisms grew to several hundred flight articles per year with sales revenue exceeding $1M per year

Pinpuller - Model P25-810-1.5R

  • GOVERNMENT/SCIENCE APPLICATIONS
  • Applications include “Hold Down and Release” of numerous satellite deployables including solar panels, communication antennae, instrument cover doors, radiators, heat shields, tether experiments, isolation system and numerous others
  • Used aboard the Mars Global Surveyor, Lunar Prospector and numerous others
