Objective:♦ To investigate of the effect of preshearing on the stress/strain
response of a polymeric liquid being stretched in microgravity.• Will investigate a controlled preshear history (from no
preshear to very strong preshear) for a specified period.Then shear flow is halted and followed by exponentiallyincreasing elongation profile axially to the polymeric liquid.
Relevance/Impact:♦ Allows optimization of polymer processing operations that
involved complex flows, i.e., both shearing (“rotation”) andelongation (“stretching”).
♦ Provide engineering design tools to optimize polymericmanufacturing processes.
Development Approach:♦ Flight experiment and design leverages off of the Extensional
Rheology Experiment (ERE) sounding rocket experiment whichstudied the uniaxial stretching flow of a polymeric liquid.
♦ Protoflight approach used for flight hardware development.♦ A high fidelity operational trainer is available.♦ Experiment is set up and run by an astronaut. Some telemetry is
viewed on the ground.
