Low Speed Wind Tunnels (LSWT)

Low Speed (subsonic) wind tunnels for research and education for testing at air speeds below Mach 0.8

ATE wind tunnels offer a high-performance wind tunnel testing facility capability with various options for future upgrades in capability and performance.


  • High Flow Quality
  • Test Sections from 200mm x 200mm to 2.0m x 2.0m
  • For low-speed wind tunnel testing.
  • Atmospheric in-draft or closed-return
  • Open jet
  • Flow conditioning with honeycomb and screens
  • PC based controls and data acquisition
  • Variable speed fan with electronic controls


Configurations offered:


For Acoustic and aerodynamic testing

Special Purpose Wind Tunnels

What follows is a small selection of ATE’s expertise in designing and implementing innovative solutions for “real life” situations, resulting from close collaboration with the end user, from initial design concept through to a finished product.

This wind tunnel was designed to test a large variety of heat exchangers. The test section is interchangeable to allow for numerous configurations of matrix’s for testing.

Bench Test Cell for Air Data Probes

This Wind Tunnel was designed and built, as a Bench Test Cell, for calibrating and testing of real-life Air Data Probes including Pitot & Pitot-Static Probes, Total Air Temperature Sensors (TATs), and Engine Inlet Temperature Sensors (P2/T2 Sensors). High contraction ratio for high quality, high speed airflow through the test cell. Used for Quality Assurance testing of newly manufactured sensors and periodic maintenance of existing (in service) sensors.

The test cell velocity is nominally Mach = 0.45 (500 f/s), and will allow for the

testing of probes with de-icing circuits energized. Probe lengths of up to 300mm

(12 inches) can be accommodated, with manual adjustment of pitch and yaw angles, providing an accurate simulation of “real flight” flow conditions for a variety of probe designs and mounting attitudes.


Test Sections


In addition to providing the complete wind tunnel, ATE can offer test sections pre-configured with test equipment.

All wind tunnels provided are engineered at our facility in the UK. Each one is bespoke designed to meet with a user's individual requirements.  We welcome the opportunity to work with our clients to develop and define their exact needs. Please feel free to contact us:


“ATE Aerotech provided a virtual centre balance and sting support for the
(NIAR) National Institute for Aviation Research - we couldnt have reached
that level of expertise without them.”
