Honeywell has a long history of providing vibration isolation systems for spacecraft components and sensitive instruments, dating back to the Hubble Space Telescope's Reaction Wheel Assembly (RWA) Isolation System (1985).
We have executed more than 40 programs involving vibration isolation systems, with more than 20 being flight programs with qualified hardware deliveries. Honeywell's vibration isolation systems provide best-in-class performance due to their linearity, predictability, high load capability and -40 dB/decade roll-off characteristic of an ideal three-parameter isolator.
The patented 'D-Strut' isolator provides stiffness properties that are independently tunable from the damping properties, a very high damping capability and a design that is free of any stiction or friction mechanisms, allowing it to function at ultra-low vibration levels (nanometer levels). D-Struts have been used to isolate a wide range of payloads (from under 10 lbs to greater than 5,000 lbs) and have been used with or without launch locks (depending on the application).
While the preference is toward passive isolation systems for their simplicity and reliability, active systems have been demonstrated on-orbit where enhanced functionality or the ultimate in performance is needed. The D-Strut technology originally developed for the space industry has also found applicability in other markets, including Aerospace, defense and automotive.
