At operation of modern air vehicles of one of the main tasks creation of comfortable conditions of life activity for crew is. The question of providing air with automatic control system of required pressure level in cabin and speed of its change, especially in the conditions of emergence of partial depressurization is particularly acute. The purpose of work is development of technique of assessment of way of management of automatic control system of air pressure in pressurized cockpit of the air vehicle at partial depressurization in the conditions of intensive maneuvering of the air vehicle in the vertical plane. Results of the conducted research can be used at justification of appearance and tactical technical characteristics of pressurized cockpits of perspective air vehicles. The developed mathematical model of assessment of way of management of air pressure automatic control system in pressurized cockpit at its partial depressurization as a result of violation of tightness in the conditions of intensive maneuvering, allows to define possibility of compensation of leak of air, without being beyond the imposed restrictions according to medico-technical requirements of safety control of life activity of the person. By means of mathematical model the assessment of the developed way providing the required accuracy and speed of pressure maintenance of air has been made. Application of way has allowed to lower pressure control error by 3-3,5 times in relation to the existing systems.
