What does the anti-icing system for the leading edge engine inlet utilize?

The anti-icing system for the leading edge engine inlet utilizes hot engine exhaust gases to prevent ice formation. By redirecting hot exhaust from the engines into the inlet areas, it effectively raises the temperature of critical surfaces, thereby preventing ice from accumulating. This method is particularly effective because it leverages existing engine output without needing additional energy sources or materials, ensuring reliability and efficiency in maintaining optimal airflow into the engine.

Utilizing hot engine exhaust is a traditional approach in aviation, particularly in jet engines, where maintaining airflow and engine performance in icy conditions is crucial for safety and operational effectiveness. Other methods, such as electrical heating elements or coatings, might not provide the same level of integrated performance as using the engine's own exhaust gases.
