SHERE hardware in GBX SHERE flight hardware

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.
