Latest Patents

Johnny Fu holds a patent for a "Thermal Protection System Ablation Sensor." This invention involves an isotherm sensor that tracks the temperatures of space vehicles by utilizing thermal protection system (TPS) materials during re-entry. The sensor operates as a function of time and surface recession through calibration, calculation, analysis, and exposed surface modeling. The design features two resistive conductors wound around a tube, with one end of each conductor connected to a constant current source. The second ends are electrically insulated from each other by a selected material that becomes electrically conductive at higher temperatures, completing an electrical circuit. As ablation occurs, the sensor conductors shorten, leading to reduced resistance in the circuit, which is continually monitored. This innovative design allows for precise temperature tracking during critical phases of space missions.
