METHOD OF INFRARED EVALUATION OF COSMONAUTE ADAPTATION TO LONG INTERPLANETARY PILOT FLOWS Russian patent published in 2017 - IPC A61B5/01 

FIELD: physics.

SUBSTANCE: study begins at least a day before the flight simulation begins under normal atmospheric pressure and the Earth's gravitational force. Using the thermal imager, the local temperature of the sole of the feet and the screened surface is determined. This surface is further used with a temperature below the revealed minimum value of the local temperature of the cosmonaut's soles by more than 0.1°C. To obtain prints of soles on the screened surface, the astronaut is asked to stand on it for 30 seconds alternately with each foot. Simultaneously, the value of the pressure exerted by the surface of the foot on the surface under investigation is recorded. Immediately after removal of the foot from the surface under investigation, a thermal imprint of the astronaut's foot is recorded on it using a thermal imager. To do this, set the thermal imager towards the screened surface perpendicular to it at a distance 1m, tuned to infrared research in the temperature range of +25-+36°C. Obtaining a colour image of the footprint on the imager's screen and take a picture of it. Further, modeling of the flight stages, the stage of adaptation of the astronauts to the aircraft and to the models of flight stages to Mars and return to Earth are carried out. Participants in the experiment are exposed to the surrounding environment continuously for many days in conditions of varying gas pressure and gravity. In the modeling of a long space flight, images of footprints are repeatedly displayed weekly under artificial conditions during 30 seconds of external pressure on the foot with a value equal to the pressure exerted prior to the beginning of the modeling of space flight. Each subsequent study is carried out at the same time of day. Snapshots of thermal footprints are transmitted to the Flight Control Center where they are archived in the form of an atlas of thermal cards of footprints, processed with a computer and analyze the dynamics of the local temperature of the thermal trace of each foot of the astronaut. In the absence of changes in the pattern of infra-red planography, the feet give out the conclusion that the astronaut has sufficient adaptation to long-term interplanetary manned flights. If new zones of local hyperthermia are detected on thermal cards, in which the temperature exceeds the initial values by more than 0.1°C, issue an opinion on the insufficient adaptation of the cosmonaut to a prolonged interplanetary manned flight.

EFFECT: safe and accurate determination of the reserves of cosmonauts adaptation to the simulated active factors of space flights.
