Abstract

Launching a precision optical instrument, such as a laser, into space presents a challenge due to the harsh structural and acoustic coupled loads that result from the launch vehicle engines. Special precautions must be implemented to protect the payload and attenuate the high frequency random vibration environment while still maintaining accurate alignment and beam pointing. Fibertek has designed, analyzed, and tested novel Ti6Al4V flexures for isolating a space laser from a high g-load random vibration launch environment. Detailed finite element analysis was done to verify structural integrity of flight hardware by assessing the applied loads, load paths, and critical failure modes. Experimental data validated the modeling and the overall conclusions.
