What is the primary function of the chine on the nose wheel?

The primary function of the chine on the nose wheel is to direct the flow of water and slush away from the engines. The chine acts as a forward-facing edge that helps divert water and slush that might be encountered during takeoff and landing. This is particularly important for aircraft operating in wet or icy conditions, as it helps to prevent ingestion of foreign substances into the engines, which could lead to performance issues or damage. By effectively managing the flow of such substances, the chine enhances safety during critical phases of flight involving ground interactions.
