Technical Description
The technology discloses a system for real-time strain measurement on flexible composite propellers during underwater operation. Triaxial rosette gauges measure blade strain, while onboard electronics amplify, filter and digitize the signals. Data passes by RF transmission from a rotating E-Bay to a stationary dummy bay for storage or transfer to a shore station.
