November 2020 — Passive Anti-Resonance (PAR) Isolator, Phase II
Safe was awarded a Phase II SBIR program by the U.S. Navy/NAVAIR to continue development of a Passive Anti-Resonance (PAR) vibration isolator system that will isolate an entire helicopter crew seat at its floor attachments. The PAR vibration isolator will adjust automatically to limit displacement during inputs near the resonance frequency. It will address and improve the health risks, discomfort, and pain of military aircrew brought on by whole-body vibration in helicopters. The MH 60S rotorcraft pilot/co-pilot seat has been selected as the target platform for the initial system design and demonstration tests. However, the PAR system can be easily adapted to other platforms and/or seat positions.
