Can the engine of altitude hypoxia aircraft work normally?

Of course. The record of flight altitude of aircraft is only over 30,000 meters, and the cruising altitude of ordinary passenger aircraft is about 1 10,000 meters. At this altitude, the cabin needs to be pressurized with oxygen (about 0.6 atmospheric pressure, equivalent to the atmospheric pressure at an altitude of 2500 meters) to maintain normal breathing. The oxygen required by the engine comes from the thin atmosphere outside the aircraft and is inhaled into the engine through pressurization.

The oxygen source is mainly gaseous oxygen, followed by liquid oxygen, and some large passenger planes also use solid oxygen sources. With the change of flying height, the oxygen regulator automatically adjusts the oxygen supply pressure, flow rate and oxygen content percentage according to certain rules to meet the physiological needs of human breathing and body surface pressurization.

There is always an emergency oxygen supply system on civil aircraft. During normal flight, cabin pressurization is used to prevent passengers from lack of oxygen. Once the cabin pressurization system fails, the emergency oxygen supply system will ensure that all passengers and passengers use oxygen in a short time while the plane descends.

Extended data:

Hypoxia caused by low oxygen pressure at high altitude. It belongs to hypoxia. This disease will happen if the compression chamber and oxygen supply system of an airplane fail at high altitude and the pilot is directly exposed to high altitude and low pressure. The human body inhales oxygen from the ambient air and exhales carbon dioxide.

This gas exchange takes place in the lungs and follows the principle of gas dispersion, that is, gas diffuses from high pressure to low pressure. At sea level, the partial pressure of atmospheric oxygen is about 159 mm Hg. At this time, the human alveolar oxygen partial pressure is about 105mm Hg, the carbon dioxide partial pressure is about 40mm Hg, the venous blood oxygen partial pressure is about 45mm Hg, and the carbon dioxide partial pressure is about 42mm Hg.
