High-capacity wide-range variable rotational rate vane testing device

Patent image
NRL

System and method for using an apparatus for measuring shear strength and viscosity of sediments that extend both the maximum rotational rate attainable and the maximum torque sustainable, and include a high data acquisition rate and data storage. The apparatus can accurately measure, for example, but not limited to, peak, evolution, and residual values of the undrained shear strength, yield, and viscous and plastic flow (including hardening and softening) characteristics of cohesive sediments at various pre-set and variable values of the rotational velocity of the vane sensor.
