Introduction

Jean-Michel Sannino is a notable inventor based in Saint-Marcel, France. He has made significant contributions to the field of propulsion technology, holding a total of 3 patents. His work primarily focuses on devices that enhance the efficiency and effectiveness of rocket propulsion systems.

Latest Patents

One of his latest patents is a "Device for heating a fluid." This innovative device is designed for use in a rocket launcher to pressurize a liquefied propellant. It features a first burner that performs combustion between a limiting propellant and an excess propellant. The first heat exchanger allows the first burnt gas from this combustion to transfer heat to the fluid. Additionally, the device includes at least one second burner where both the first burnt gas and some limiting propellant are injected to perform a second combustion. The second burnt gas flows through a second heat exchanger, further transferring heat to the fluid. The design incorporates burnt gas tubes within a common overall heat exchanger, optimizing the heat exchange process.

Another significant patent is the "Jet propulsion device and fuel supply method." This reaction propulsion device includes a first feed circuit for a main thruster, which feeds a first propellant through a branch connection downstream from a pump of a first turbopump. This branch connection passes through a first regenerative heat exchanger and a turbine. A second feed circuit for a second propellant is similarly structured, ensuring efficient fuel supply to the main thruster. The design also connects at least one secondary thruster downstream from the turbines of both turbopumps.
