Title: Innovations by Robert S. Mazzawy
Introduction
Robert S. Mazzawy is an accomplished inventor based in South Glastonbury, Connecticut. He has made significant contributions to the field of engineering, particularly in the design and performance of fan-jet engines and axial flow compressors. With a total of 3 patents to his name, Mazzawy's work focuses on enhancing engine performance while maintaining efficiency.
Latest Patents
Mazzawy's latest patents include innovative treatments for rotor cases and compressor blades. The first patent addresses the rotor case treatment, which enhances stall margin without degrading engine performance. This is achieved by incorporating a passageway that removes low momentum flow from the main flow stream. The critical aspect of this design is the precise location and amount of flow being removed, which must not exceed 8% of the total flow in the fan rotor. Anti-swirl vanes and strategically sized passages ensure that the flow is returned to the main stream at an increased velocity.
The second patent focuses on case treatment for compressor blades. This invention involves treating the outer shroud of an axial flow compressor to remove low momentum flow adjacent to the tips of the blades. Similar to the rotor case treatment, it is crucial that no more than 12% of the total flow in the compressor rotor is removed. The design includes anti-swirl vanes that help manage the swirl component of the removed flow, ensuring that the strong mainstream flow remains intact.
