Sensors for Demanding Applications

Aerodynamic ground test facilities and flight vehicles rely on robust, high-fidelity, high-accuracy instrumentation to make critical flow measurements. Wall shear (i.e. skin friction) is one such parameter and directly influences the aerodynamic efficiency, controllability, and performance.

Ahmic’s direct-measurement, non-intrusive, wall shear sensors have proven to be a vital tool to characterize complex flow systems, gather valuable insight into fundamental flow-physics, validate and refine predictive models, and help extrapolate ground test data to flight.

Commercial Solutions

Ahmic’s commercial line of wall shear sensors are designed for a broad application and performance spectrum. Our patented direct-measurement technology is capable of characterizing the local wall shear, the direction of the flow, and shockwave interaction through a single-point measurement source. Our sensors can be tailored to your unique integration requirements and require no additional support equipment to operate.

Typical Specifications:

Small profile: < 0.25 in. OD
Wall shear range: ± 25 - 500 Pa
Measurement resolution: < 1 Pa
Frequency response: 500+ Hz
Operating Range: up to +350°F
NIST-traceable measurement

Customizable Features:

Shockwave detection & compensation
Surface matching (contour, roughness, etc.)
Low-profile height & cable arrangement
Adaptable mounting flange & seal design
Custom shims for flow surface alignment
