Latest Patents
Philippe Le Helley holds a patent for a "System and method of controlling pressure oscillations of hydrodynamic origin for a solid propellant thruster." This invention provides a system for passively controlling pressure oscillations in a solid propellant thruster. The system includes at least one insert positioned transversely within the thruster body, which has a non-axisymmetric opening. This design generates a three-dimensional effect on the flow, preventing the formation of axisymmetric turbulent modes that can lead to instability. The control system effectively breaks the symmetry of the flow, thereby mitigating the turbulence that can compromise the performance of the thruster. This innovative system is applicable to existing thrusters, enhancing their operational reliability.
