Yamaha has filed a new patent for its R1 superbike, showcasing advanced active aerodynamic technology aimed at improving cooling and high-speed performance.
Yamaha’s Dive into Active Aero
Active aerodynamics isn’t entirely new to the motorcycle world, with systems like the Moto Guzzi V100 Mandello already featuring simpler versions. However, Yamaha’s patent application for the R1 reveals a more performance-focused approach.
The core idea involves new bodywork with air outlets that can automatically open or close. This intelligent system adapts to the bike’s specific needs in real-time.
How the System Works
The updated side panels of the R1 are designed to be more encompassing than previous, more open designs. These panels integrate special outlet ducts, which are crucial for managing airflow.
When open, these ducts allow hot air to efficiently escape after passing through the radiator, significantly boosting cooling performance. Conversely, closing these ducts provides a key aerodynamic benefit by reducing drag, which enhances the bike’s speed capabilities.
Two Design Concepts Emerge
Yamaha’s patent illustrates two distinct versions of this active aero design, both operating on the same principle. One version features a single large outlet duct on each side of the fairing, equipped with variable vanes.
The second, more elaborate design, incorporates a pair of smaller outlets on each side. This dual-outlet setup is expected to offer even greater cooling potential and more precise control over the airflow.
Intelligent Control and Benefits
The movable vanes within these ducts are operated by a compact electric step motor and a belt drive mechanism. This allows the bike’s Engine Control Unit (ECU) to precisely adjust the vanes’ position.
The system gathers data from various sources, including engine temperature, outside air temperature, throttle position, and vehicle speed. This comprehensive data allows the ECU to determine whether to prioritize engine cooling or aerodynamic efficiency at any given moment.
Implementing such technology on a road bike could yield significant advantages. It promises enhanced performance and improved fuel efficiency, potentially leading to reduced emissions. This innovation could also find applications and provide valuable insights for Yamaha’s racing programs.
