Celebrating Innovation: A New Patent for the 21st Century Prony Brake

We’re proud to announce that Aaron Warsaw, Dyno Tech’s lead designer, has secured his second patent in just three years. His latest innovation—the axial force Prony brake dynamometer—marks another groundbreaking advancement in 21st-century dynamometer design.

With this new concept, Aaron has successfully achieved his major design goals: to create an economical, high-performance power testing solution for a wide range of applications, especially focused on smaller to mid-sized agricultural tractors. Prony brake dynamometers have long been trusted for dynamic load testing at low RPM and high torque, and this new design raises the standard.

What makes this patent particularly exciting:

• Axial Force Engagement: A novel method of applying frictional resistance via axial force—departing from traditional radial force systems.
• Innovative Torque Measurement: Reactive forces are harnessed in a new way to measure torque, effectively eliminating piston slap, a long-standing issue in radial brakes.
• Design Originality: This dynamometer introduces two first-ever innovations in Prony brake history, qualifying it as a fully original patent—not a variation or refinement of previous concepts.

For decades, Prony brake systems have evolved through countless designs, shapes, and capacities. True innovation demands bold thinking—and Aaron has delivered just that. We’re honored to have him as part of our team and proud to add another visionary design to Dyno Tech’s legacy of excellence.
