MUMBAI, India, Aug. 22 -- Intellectual Property India has published a patent application (202311040982 A) filed by Shubhangi Sundaria; Amritansh Kumar Bhagat; and Dr. V. R. Sanal Kumar, Noida, Uttar Pradesh, on Dec. 16, 2023, for 'discovery of a truncated aerospike nozzle with optimum cowl length for the effective thermal management of single stage to orbit vehicles.'
Inventor(s) include Shubhangi Sundaria; Amritansh Kumar Bhagat; and Dr. V. R. Sanal Kumar.
The application for the patent was published on Aug. 22, under issue no. 34/2025.
According to the abstract released by the Intellectual Property India: "The invention relates to a method for mitigating the cascading sonic fluid throat effect in high-speed fluid systems, particularly in nozzles with compressible reacting viscous flows and spike geometry. The method optimizes the geometry of truncated aerospike nozzles and cowl lengths while injecting a high heat capacity ratio (HCR) fluid at targeted locations within the nozzle. This approach counteracts Sanal flow choking caused by Streamtube compression, reducing shock wave formation and entropy generation. The technique ensures smoother flow transitions, minimizes excessive heating, and enhances the efficiency, stability, and performance of systems such as rocket propulsion, jet engines, and other supersonic fluid flow applications."
