Abstract: We must determine if we can incorporate our existing normobaric simulated altitude technology into a hypobaric chamber so that the chamber may first climb to 20,000 feet under normobaric mixed gas conditions, and then climb another 10,000 feet using low pressure, maintaining a steady 30,000 feet. Alternatively, we need to determine if we can we create a modular room adjacent to the hypobaric chamber that will allow students to experience 30,000 feet of simulated normobaric altitude? We believe that the answer to both of these questions is yes, we can. The first approach will require testing new oxygen sensors that can operate with our existing control system in a presurized environment. We will also test hoses, valves and seals that will allow our hypoxic air generators to perform without being damaged by the changes in pressure. In the second approach, we will need to design and develop a satisfactory altitude room that will be sealed sufficiently with an appropriate entry/exit system to allow for climbing to and maintaining 30,000 feet.
Benefits: The benefits of our primary approach are that students and instructors will not be exposed to the risk of DCS, and have the opportunity to experience both pressure altitude decompression and high altitude hypoxia in the same chamber without the requirement for a ROBD. Our alternative approach achieves the same results, but requires instructors and students to move to a separate room for the higher altitude training. Potential commercial applications include the acceptance of these systems by U.S. and foreign commercial and general aviation training companies, by other U.S. military units, by foreign military units, and by foreign aeronautical authorities involved in aviation training.
