He has been instrumental in developing advanced technologies that enhance the performance and safety of rocket propulsion systems. With a total of 2 patents, Lushis has made a lasting impact in his field.
Latest Patents
Lushis's latest patents include a "Braided preform for refractory articles and method of making" and a "Thrust reversal system." The braided preform fabrication is designed for annular refractory articles, such as the throat section and exit cone of a rocket motor nozzle. This innovative design utilizes closely spaced radially oriented carbon rods and carbon fibers braided in a triaxial braid, resulting in a unique 4-D fiber architecture. The process involves multiple steps, including vacuum impregnation with pitch and high-pressure treatment to convert the pitch to coke, ultimately forming a robust braided preform.
The thrust reversal system is another remarkable invention that aims to reduce, neutralize, and reverse the thrust vector of solid propellant rocket motors. This system employs a movable conical piston that covers small ports arranged around the aft dome of the rocket motor. When actuated, the piston retracts to uncover the ports, allowing combustion gases to be redirected, thus controlling the thrust vector effectively.
