Latest Patents

James B. Scott holds a patent for a Thermal Protection System Ablation Sensor. This advanced sensor tracks the temperatures of space vehicles by utilizing a thermal protection system (TPS) material during vehicle 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 is achieved through measured end-to-end voltage changes or current in the circuit. Additionally, thermocouple and/or piezoelectric measurements provide consistency checks on local temperatures.
