Inside the Lab: How We Re-engineered Golf Ball Aerodynamics for Maximum Distance

Spherical aerodynamics

When airflow moves over the surface of a sphere, a wake region is formed due to boundary layer separation, which increases aerodynamic drag. By optimizing the shape and surface structure of the sphere, airflow separation can be reduced, resistance lowered, and flight distance increased. This allows the sphere to maintain a more stable trajectory in flight, reducing energy loss and achieving greater flying distance.

By adjusting the diameter, hardness, and surface roughness of the ball, the lift-to-drag ratio can be optimized. A higher lift-to-drag ratio means that the ball can utilize aerodynamics more efficiently during flight, reducing energy loss, increasing flight distance, and improving hitting performance and competitive advantage in matches.

Turbulence Control Theory

The formation of a turbulent boundary layer affects the airflow over the surface of a sphere. By studying the characteristics of turbulence, effective surface structures can be designed to control boundary layer behavior, reduce energy loss caused by turbulence, and improve the flight stability and distance of the sphere.

By optimizing the airflow structure at the rear of the sphere, the generation of vortices in the wake can be reduced, thereby lowering aerodynamic drag. This helps improve the sphere's flight speed and distance, enhancing the accuracy and stability of hitting.

Surface roughness adjustment

Surface roughness affects the adherence of airflow and the thickness of the boundary layer. By adjusting the surface roughness, the position of airflow separation can be controlled, turbulence generation can be reduced, aerodynamic drag can be decreased, and the flight distance of the sphere can be increased.

Using advanced surface treatment processes (such as sandblasting, laser engraving, etc.), the surface roughness is precisely controlled to ensure uniformity and consistency of the dimple structure, enhancing the aerodynamics and durability of the sphere.

Through wind tunnel tests and actual hitting tests, verify the specific effects of different surface roughness on the flight distance and stability of the ball, providing data support for design optimization.

Pneumatic Coating Technology

Choosing coating materials with a low coefficient of friction and high durability can reduce the frictional resistance between the airflow and the surface of the ball, enhancing the ball's flight speed and distance. At the same time, the coating material should have good wear resistance and aging resistance to ensure long-term performance.

By precisely controlling the coating thickness, balance the aerodynamic performance and the weight of the ball. A coating that is too thick may increase the ball's weight, affecting its flight distance; a coating that is too thin may not effectively reduce friction. The optimal thickness needs to be determined through experimentation.

Data collection and analysis

Analyze the pressure values and distribution patterns at various points on the surface of the sphere, identify high-pressure and low-pressure areas, evaluate the effect of dent structures on optimizing pressure distribution, and provide data support for subsequent designs.

Manufacturing Process Innovation

Using precision injection molding technology to ensure the accurate replication of the spherical shape and dimple structure, improving product consistency. By optimizing mold design and injection molding parameters, production defects are reduced and product qualification rate is increased.
