Latest Patents

One of Okpara's latest inventions is the **Gas turbine disk cavity ingestion inhibitor**. This supplemental air cooling system is designed to mitigate the ingestion of hot flow path gases into the circumferential locations of turbine disk cavities. By implementing a series of cooling air holes on each side of the turbine nozzle airfoil trailing edges, Okpara created a solution that generates dynamic pressure cooling air jets. These jets effectively redirect incoming hot air, resulting in decreased hot gas ingestion, reduced temperatures of disk rotor and static structural metals, and an overall enhancement in the gas turbine engine's performance through improved specific fuel consumption.

Another significant invention by Okpara is the **Gas turbine airfoil with aft internal cooling**. This innovative gas turbine vane or blade features a unique internal structure that facilitates effective cooling across various pressure ratios. The design incorporates an air inlet passage connected to an inner cooling cavity, with strategically placed deflectors, turning members, ribs, and deflecting pins. This arrangement ensures that cooling air is efficiently directed through the cavity, minimizing pressure loss and maintaining optimal airflow, which ultimately contributes to the enhanced cooling efficiency of the airfoil.
