About Dhanesh Ayyappan
Propulsion engineer specializing in experimental studies, injector design, and rocket engine testing. My PhD focused on fluid behavior under high-pressure, high-temperature supercritical conditions, providing a strong foundation in combustion and propellant flow physics. Currently, I lead the engineering team at Hathor Rockets in the design, development, and testing of a semi-cryogenic rocket engine, translating research into working hardware. I am passionate about building reliable propulsion systems and advancing space technology through hands-on experimentation and innovation.
