Latest Patents

Dumont holds a patent for a liquid propellant rocket engine with parallel auxiliary flow. This rocket engine features an injection device that includes a single injection plate. The central portion of this plate defines the end of the burn zone of the combustion chamber. It contains first propellant injectors with a high mixing ratio, which are adapted to the conditions under which hot gases are produced in the burn zone. The peripheral portion of the plate is in the form of a ring that defines the end of an annular cavity of a gas generator. This portion contains second propellant injectors with a low mixing ratio, suitable for the conditions in the gas generator. The gas generator is integral with the combustion chamber, and the annular cavity is separated from the burn zone by a cylindrical wall that extends axially perpendicularly to the injection plate and is fixed in a sealed manner.
