Sensor Integrated Pilot Mask for On-Board, Real-Time, Monitoring of Pilot Breathing Gas
MetadataShow full item record
A pilot’s job is unique in the demands it places on the human body, and many serious conditions can arise to impact pilot performance and pose a threat to mission completion and pilot safety. The gas environment of the flight mask contains key indicators of the pilot’s physiological state, including information on oxygen inhaled and carbon dioxide exhaled. This information is used to determine hypoxia, hyperoxia, hypercapnia, and hypocapnia. A fiber optic-based sensor system, integrated in the pilot mask, has been developed to monitor in real time, during flight missions, the pilot breathing gas levels. Monitoring the partial pressure of oxygen and carbon dioxide in the pilot mask enables real-time closed loop control of the on-board oxygen generation system, based on a direct reading of what the pilot is actually breathing. The pilot Mask Sensor (MASES) system incorporates luminescence sensors for pO2, pCO2, relative humidity, pressure, and temperature in a compact probe inserted in the pilot mask; it is based on sensor technology developed for gas monitoring in space suit systems, which was supported by NASA under the Small Business Innovation Research program. Relevant requirements for the MASES system include sensor operation while wet, operation at reduced pressure, ability to withstand rapid decompression, operation in a pure oxygen atmosphere, low power consumption, a compact readout unit, and flexible miniature sensors; many of these are shared with gas monitoring requirements in space suits. Data are presented from tests conducted with human subjects in an altitude chamber and in a centrifuge.
