METHOD FOR REGULATING AIR PRESSURE IN AIRCRAFT CABIN UNDER SPECIAL FLIGHT CONDITIONS Russian patent published in 2021 - IPC B64D13/04 

FIELD: aircraft air conditioning systems.

SUBSTANCE: invention relates to an aircraft air conditioning system. A method for regulating air pressure in a pressurized cockpit of an aircraft, based on measuring the angle of deflection of the aircraft control stick, calculating the flight altitude of the aircraft at a time interval Δt_c after deflecting the control stick of the aircraft and the calculated vertical flight speed of the aircraft to achieve the calculated altitude, calculating the required value of air pressure in the pressurized cabin at the estimated flight altitude of the aircraft and the required rate of pressure change to achieve it, with the use of which the air pressure in the pressurized cabin is regulated. Additionally, after a time interval Δt_c, the pressure in the aircraft cabin is measured and compared with the required pressure. If the measured pressure is less than the required pressure in the cabin of the aircraft, then a decision is made on the presence of depressurization of the pressurized cabin, and the possibility of compensating for air leakage by the pressure control system in the cabin is determined. If it is impossible to compensate for the air pressure, a decision is made to lower the aircraft to an altitude corresponding to the permissible pressure in the cockpit.

EFFECT: aircraft air conditioning system improvement.
