AI Technical Summary
Gas turbine engines operating in desert environments ingest fine sand and dust particles that accumulate in turbine component cooling circuits, impeding cooling and reducing the life of airfoils and nozzles, leading to increased repair costs and downtime.
A turbine nozzle with dust-tolerant impingement cooling is implemented, featuring a double-wall impingement tube with strategically aligned and differently sized apertures that reduce particle accumulation by accelerating and aligning sand and dust particles for efficient ejection, while maintaining effective cooling fluid flow.
The solution effectively minimizes particle accumulation within the impingement tube, enhancing cooling efficiency and extending the life of turbine vane airfoils and nozzles, thereby reducing maintenance costs and downtime.
