Novosibirsk State Technical University (NSTU) has developed software for calculating the work of the circulatory system of pilots and astronauts, taking into account morphological properties, gender and age. The program allows you to study the influence of external physical factors on the human body to further compensate for stress.
The Department of Technical Thermophysics of the Faculty of Aircraft of NSTU-NETI presented an innovative program for calculating the human circulatory system, taking into account age, gender, type of motor activity and morphological properties of the body — aorta, arteries, arterioles and capillaries. Special attention was paid to the study of the effect of blood rotation on the functioning of the circulatory system. The development makes it possible to determine the effect of external factors on the functioning of the circulatory system: weightlessness, linear accelerations and overloads.
"One of the areas of work of our department is to study the effects of physical activity on the human body during training on various types of simulators. With this program, we see how external factors affect the functioning of the circulatory system, and we can offer types and intensity of training that will compensate for the negative effects of these factors," said Alexander Chichindaev, Professor of the Department of Technical Thermophysics at the Faculty of Aircraft, Doctor of Technical Sciences.
Students of the specialty "Life Support systems and aircraft equipment" of the Faculty of Aircraft actively participated in the development of the program, who collected a large amount of background information, taking into account gender, age, body condition and flight conditions. "It took more than 10 years to fill the program with biological data. In addition, a lot of effort went into setting up the Bernoulli equation, which is used in hydrodynamics to describe the flow rates and pressures of hydraulic systems for humans. The result is a unique product designed to study the effects of external factors on humans," he said.
The development of the Department of Technical Thermophysics, which received a certificate for computer programs in October 2025, was evaluated by scientists from the Moscow Aviation Institute. Colleagues noted the unique approach to solving the problem. "From a scientific perspective, our approach is really unusual. As a rule, scientists think in terms of calculating pressure and flow rates in the elements of the hydraulic system of an aircraft, and we take the Bernoulli formula and "shift" it to humans," said Alexander Chichindaev.
