SAFE INC — Department of Defense SBIR Phase I: N191-015

Description

Whole-body vibration is one of the factors causing military aircrew discomfort and pain during and after flight operations. Health risks are a concern after only a few hours of continuous flight at the seating positions on some aircraft. Safe proposes to develop a passive vibration isolator that isolates an entire helicopter crew seat at its floor attachments. The isolator adjusts automatically to inputs near the resonance frequency, but uses simple passive devices that do not require aircraft power. This approach minimizes the complexity of seat and aircraft integration to keep qualification testing and production costs low enough for successful commercialization.
