MUMBAI, India, Oct. 26 -- Intellectual Property India has published a patent application (202611115305 A) filed by Chandigarh University on September 25, 2026, for Dual-Fillet Lobe Strut Combustor With Integrated Step- Induced Flow Stabilization.
Inventors include Krishan Kumar Madhukar; Tiokang Frank Bell; Dev Sharma; Simran Kaur; Ajin Branesh; and Gurmail Singh Malhi.
The application for the patent was published on October 23, 2026, under issue no. 43/2026.
Abstract: The present invention relates to a supersonic combustor, particularly for a scramjet engine, comprising a streamlined strut disposed in a supersonic airflow passage. The strut includes 5 a tapered leading-edge section, a gradual transition section, a symmetrical dual-fillet lobe region, a fuel injection region and an integrated step or shoulder. The dual-fillet lobe region divides or guides incoming airflow and forms controlled shear layers with injected fuel to enhance fuel-air mixing. The step or shoulder induces localized flow separation downstream and thereby forms a recirculation zone configured to promote fuel-air 10 interaction and provide flame stabilization. The strut further includes a gradual flow-guiding contour extending toward a downstream combustion section to reduce abrupt flow disturbances and shock-induced losses.
