IC2 announced today that NASA has selected the company for a new Phase 2 contract from the 2018 SBIR program, accelerating critical R&D into two-dimensional shear-stress sensing. Under this new two-year contract, IC2, in partnership with the University of Florida, will continue developing a dual-axis, instrumentation-grade capacitive shear stress sensor for subsonic and transonic measurements. Following a successful Phase 1 program, the Phase 2 continues to build from the current line of shear stress sensing products, IC2's DirectShear Sensors, extending the technology to two dimensions of simultaneous sensing of wall shear stress.
The sensor system enables localized, non-intrusive, vector measurement of mean and fluctuating wall shear stress for characterization of complex boundary-layer flows in ground-test facilities. The differential capacitive measurement approach offers high sensitivity to in-plane shear stress as well as common-mode rejection of pressure fluctuations. Two sets of differential capacitors provide shear stress measurement capability in two orthogonal directions, creating a wall shear stress vector. Backside electrical contacts using IC2’s patent-pending fabrication and packaging process enable flush mounting with the test article surface. The proposed design approach facilitates design optimization for multiple applications and flow conditions.
