Wind Tunnel Controller

Precision-Controlled Aerodynamic Testing

 

The nimeṣa™ Wind Tunnel Controller is a high-performance, compact control system engineered specifically for managing airflows in wind tunnel environments. Designed for research institutions, laboratories, and aerospace test facilities, this system ensures precise, real-time control over electric fan motors and airflow profiles — simulating complex aerodynamic conditions with exceptional fidelity.

Whether you're testing aircraft models, automotive shapes, or scientific prototypes, the nimeṣa Controller provides an intelligent interface between your experimental models and the aerodynamic environment they require.

Key Features

  • Real-Time Airflow Regulation
    Seamlessly controls electric fans and drive systems to manage air velocity, pressure, and turbulence inside wind tunnels with precision.

  • MATLAB Simulink Integration
    Comes with native support for MATLAB Simulink, enabling easy implementation of complex control logic and live system modelling without third-party tools.

  • Precision PWM Control
    Generates customizable, high-fidelity waveforms for motor control, supporting both open-loop and closed-loop operation modes.

  • Wireless Programming Support
    Program and update your system remotely, making test setups more flexible and less hardware-dependent.

  • Versatile I/O Interfaces
    Includes analogue inputs/outputs and 8-channel digital servo motor control, offering robust compatibility with a wide range of instruments and sensors.

  • Time Synchronization
    Achieve better coordination in multi-component test setups with improved real-time synchronization.

  • Driver-Free Deployment
    No additional software licensing is required — the controller comes with pre-configured software, reducing setup time and total cost of ownership.
