MUMBAI, India, July 30 -- Intellectual Property India has published a patent application (202641086970 A) filed by Indian Space Research Organisation on July 16, 2026, for System For Evaluating Hydraulic Resistance Of An Integrated Liquid Rocket Engine Injector Head.
Inventor includes Rafeeque T A.
The application for the patent was published on July 24, 2026, under issue no. 30/2026.
Abstract: The present disclosure relates to a system (100) for evaluating hydraulic resistance of an injector head integrated with an engine chamber of a liquid rocket engine under gaseous backpressure conditions. The system (100) includes a liquid-flow supply interface (5) configured to supply water to the injector head, and a blockage inducer assembly (4) insertable into the engine chamber via an engine exit. The blockage inducer assembly (4) includes a cone (1), an injection tube (2), and a cold gas inlet (3). The cone (1) restricts an annular flow area between the cone (1) and a wall of the engine chamber. A cold-gas supply arrangement delivers cold gas via the injection tube (2) to maintain gaseous backpressure at an exit side of the injector head. A water-and-gas mixture outlet (6) discharges a water-and-gas mixture. A pressure- measurement arrangement determines pressure difference for evaluating hydraulic resistance.
