Traverse System

About Traverse System

Overview

A precision traverse system for subsonic wind tunnels, designed to accurately position pressure probes for detailed wake analysis and flow field mapping. The system combines motorized cross-flow movement with manual streamwise adjustment, ensuring flexibility and ease of use.

 Key Features

• Accurate Flow Mapping: Ideal for wake and velocity profile studies
• Stepper Motor Driven (Y/Z Axes): High resolution, repeatable positioning
• Manual X-Axis Adjustment: Discrete streamwise positioning
• Low-Backlash Design: Smooth, precise motion
• Advanced Sealing System: Maintains flow integrity

Technical Datasheet (Typical)

• Axes of Motion:
• Y / Z: Motorized (stepper-driven)
• X: Manual (slot-based positioning)
• Position Accuracy: Application-specific (customer-defined)
• Sweep Area: Customized to test section size
• Repeatability: High precision with minimal backlash

Design & Construction
