About this technology
Overview
Developed by innovators at the NASA Marshall Space Flight Center, the Periodic Wave Disc Brake Rotor offers improved performance for potential applications in racings cars, motorcycles, and in particular for electric vehicles (EVs) equipped with regenerative braking systems. NASA's periodic wave rotor technology is a suite of rotor designs that provides dramatic weight reduction along with high heat dissipation, two of the primary challenges associated with high performance braking systems. Increasing any vehicle's racing performance involves decreasing the rotational moment of inertia and brake-system weight, which allow the vehicle to accelerate faster, change direction better, and require less energy when doing all of the above. For racing cars, reducing braking system weight is all about achieving better lap times. For any popular EVs, however, decreased electrical energy expenditure provides increased travel range. NASA's Periodic Wave Disc Brake Rotor can be easily implemented into any existing vehicles with either hub-mounted or wheel rim-mounted brake systems.
