HOL-TRIN
Custom Modular Design

Wind Tunnels

Build a wind tunnel to meet your unique testing needs. Individually controlled fans create complex flow profiles — turbulence, wind shear, time-variable wind, and more. Modular and portable, unlike anything else on the market.

HOL-TRIN Wind Tunnel

Unlimited Flow Profiles

Individually controlled fans let you create turbulence, wind shear, time-variable wind, and complex spatial flow distributions — impossible with conventional tunnels.

Modular & Portable

Assemble and disassemble in minutes. Ship globally. Configure Wind Wall, Convergent, Test Section, or Divergent layouts from the same modular components.

Python & Software Control

Script complex wind profiles with Python or use the WindControl Navigator GUI. Full API access lets you sync tunnel control with thrust stand data acquisition.

Choose Your Wind Tunnel Configuration

Every configuration is built from the same modular Windshaper components. Mix and match to create the test environment your application demands.

Wind Wall configuration

Wind Wall

Open test area configuration for large-scale testing without spatial constraints. Ideal for full-drone aerodynamic evaluation.

Convergent wind tunnel

Convergent

High-precision convergent section accelerates and smooths the airflow for uniform, controlled inlet conditions into your test section.

Test section wind tunnel

Test Section

Enclosed test section with controlled boundaries for repeatable aerodynamic measurements and force balance testing.

Divergent wind tunnel

Divergent

Divergent diffuser section decelerates flow downstream of the test section for efficient energy recovery and reduced noise.

WindControl Navigator Software

WindControl Navigator

Wind Tunnel Software

Create multidimensional wind profiles u=f(x,y,t) with manual control or full Python scripting. Design steady-state flows, gusts, turbulence sequences, and spatial gradients — then replay them with sub-second precision across all fan modules simultaneously.

  • Spatial flow mapping u(x,y)
  • Time-variable profiles u(t)
  • Gust and turbulence generation
  • Python scripting API
  • Integration with WindProbe 3D
  • Sync with Flight Stand software
  • Export flow profiles & logs

Need an Open Test Area?

Wind Walls provide the same Windshaper fan technology in an open configuration — no enclosed test section, no spatial constraints. Perfect for full-size drones and larger test objects.

Wind Walls

Wind Walls

Flow generators for aerodynamic testing up to 20 m/s / 45 mph. Array configurations from 2×1 to 8×4 fan modules. Same software, same modular components — open to the world.

What Researchers Say

From flight labs to university wind engineering departments — engineers share how the Windshaper changed their testing capability.

★★★★★

"The system has been working well for us. Most recently we used it for static testing of a powered glider platform to supply incoming airflow over the fuselage — measuring power draw and heat buildup throughout the fuselage with incoming flow, simulating slow-speed flight."

Chris White

Research Engineer

Raspet Flight Research Laboratory, Mississippi State University

★★★★★

"The Tyto thrust stand and 2×2 Windshaper have been game-changers in our propeller development. For a windmilling drone like ours, custom propellers are critical — and Tyto's tools have helped us uncover performance gains we'd never see in static tests."

Will Hasting, PE

CEO

Angel Aerial Systems

★★★★★

"The Windshaper has been an invaluable tool in our research to better understand the interactions between flow and drones in windy and gusty conditions. Using the Windshaper and bubble tracking, we were able to precisely characterize how LaDrone reacts to wind gusts!"
