Where should the chines be located for a dual nose wheel installation?

The correct placement of chines for a dual nose wheel installation is specifically on the outside of the tires. The purpose of these chines is largely aerodynamic; they help to control airflow around the landing gear. By positioning them on the outside, they efficiently redirect the airflow away from the tires and reduce drag during takeoff and landing. Additionally, this placement can help prevent damage from debris that might be kicked up by the wheels.

On the inside of the tires, the airflow characteristics differ significantly, which would not benefit from having the chines located there. Having them only on the front of the tires may not provide sufficient aerodynamic efficiency. Meanwhile, placing them on both the inside and outside could complicate airflow management and achieve contradictory effects. Therefore, focusing solely on the outside of the dual nose wheels maximizes the aerodynamic advantages while maintaining optimal performance.
