A servo-motor based control system for high-speed wind tunnel flow control equipment

ATS offers precision motion control systems for all aeronautical testing applications. Our systems feature very high accuracy and user-friendly control interfaces to maximize test automation and efficiency.

Examples of motion control applications at ATS include:

  • Powered, electrically-driven wind tunnel model components and surfaces
  • Attitude positioning for custom wind tunnel model mounts/balances
  • Wind tunnel flow-control devices
  • Mechanical testing equipment

Our miniaturized wind tunnel model surface control system can be integrated inside most model designs. Surface angular deflections can be quickly adjusted and controlled to within a small fraction of a degree.

Exclusive, highly rigid ATS actuator design allows most applications to employ affordable drive systems based on stepper motors. Systems with higher power and/or dynamic requirements may employ servo motor or hydraulic systems.

Systems optionally may receive control inputs from customer equipment and output positional data at speeds up to 100 Hz.
