Physical Optics Corporation — Department of Defense SBIR Phase I: A17-076

Description

To address the Army need for a low profile strain measurement system for parachute suspension lines, Physical Optics Corporation (POC) proposes to develop a new Smart Parachute Suspension Line (SPASL). It is based on novel construction of suspension and control cords using core-conducting bi-component fiber yarns in a double braid rope configuration. Specifically, the innovation in utilizing low and high conductivity synthetic fiber yarns in core and cover braids will enable the SPASL to monitor strain on the cord while maintaining electronic link along the suspension line. As a result, this proposed technology offers independent strain monitoring on individual suspension and control lines of the parachute and power and data link between the payload and canopy, which directly address the Army requirements. In Phase I, POC will demonstrate the feasibility of SPASL by performing analytical calculations and simulations and conducting laboratory experiments using a benchtop prototype. In Phase II, a full scale SPASL prototype will be built based on the Phase I results and findings. At the end of Phase II, the SPASL technology is expected to reach technology readiness level (TRL)-4 to -5 and be ready for airdrop testing in a relevant environment.
