Application Of Oxygen Regulator In Flight

December 08,2021

When the aircraft flies at a high altitude, because the atmospheric pressure decreases with the increase of altitude, the oxygen concentration in the external air can not meet the needs of the pilot. Therefore, the pilot needs to supply mixed air or pure oxygen with different oxygen concentrations according to the flight altitude through the oxygen regulator.


During the mission of military aircraft, due to its fast flight speed and drastic change in flight altitude, it is required that the oxygen supply equipment put forward higher requirements for the oxygen concentration of oxygen provided by pilots.

Why use an oxygen regulator in flight?


Due to the reduction of atmospheric pressure at high altitudes, the oxygen concentration of the air inhaled by the pilot can not meet the needs of the pilot. The main task of the oxygen regulator is to control the oxygen concentration provided by the pilot inhaler and prevent the reaction or symptoms caused by hypoxia.


According to the requirements of aviation physiology, when the flight altitude is below 1500m: the pilot mainly inhales the air of the external environment, and its main purpose is to reduce oxygen consumption.


When the flight altitude is in the range of 1500-9000m: with the increase of flight altitude, the oxygen partial pressure of the pilot's inhaled gas decreases. To ensure that the oxygen partial pressure level of the pilot's inhaled gas meets its needs, the oxygen regulator must increase the oxygen concentration of the inhaled gas with the increase of altitude.


When the flight altitude of the aircraft is above 9000m, the oxygen regulator generally supplies pure oxygen. And when the flight altitude of the aircraft continues to rise, the oxygen regulator adopts a pressurized oxygen supply.


Working process of oxygen regulator


When the pilot inhales, the internal pressure of the oxygen mask decreases, and the suction valve in the mask opens. At this time, the controller opens the oxygen and air valves by controlling the motor to make the gas pass through the suction valve.


When the pilot exhales, the exhalation valve in the mask opens and the inhalation valve closes, the supply gas no longer flows into the mask, and the oxygen and air valves are closed at the same time.


During the flight of the aircraft, the oxygen regulator controls the oxygen flow and airflow by adjusting its oxygen and air valves, so that the concentration of the air inhaled by the pilot can meet the requirements of the pilot for different oxygen concentrations of the inhaled gas at different altitudes.


Generally speaking, the oxygen regulator mainly fixes the opening of the air valve. By adjusting the opening of the oxygen valve, the oxygen concentration of the gas supplied by the oxygen regulator to the pilot meets the pilot's requirements. Because the airtightness between the valve seat and the valve plate of the flat valve is better, the valve of the oxygen regulator worn by pilots generally adopts the flat valve.
