Latest Patents

Among his latest innovations is the development of stable hybrid rocket technology. This hybrid rocket engine achieves stable and highly efficient combustion by utilizing a core flow of fuel-rich gas generator gases, which are surrounded by an annular injection of oxidizer. The fuel-rich gas vaporizes and decomposes the oxidizer, such as nitrous oxide, preparing it for effective combustion. The combustion products are then expanded through a nozzle to create thrust, making this engine suitable for upper-stage applications.

Another significant patent is the monopropellant cascade rocket engine, which uses nitrous oxide as the propellant. This engine features a catalyst bed at the end of a diverging combustion chamber, injecting a first flow of monopropellant to ignite it. Additional injections of monopropellant follow, utilizing the previously decomposed monopropellant to ignite the downstream flow. This innovative design allows for precise control of thrust through a regulating control valve.
