Is it true that people are inhaled into airplane engines?

There are records of people being inhaled into aircraft engines, whether it is military aircraft or civil aircraft.

The typical incident is 199 1, in which a recruit is sucked into the air inlet of A6E intruder. Since the foreign body inhalation prevention device was started, the pilot turned off the engine in time, and the recruits were lucky enough to survive and retired with honor. Because there is an air inlet in front of the fighter engine, it can ensure that the engine can intake air normally in various postures, and the recruits are stuck in the air inlet and are not inhaled into the compressor.

If it is a civil plane, it will definitely die. First of all, the civil aircraft has no imported guide vanes, and it is directly a fan blade made of steel, titanium or carbon fiber, with a rotating speed of at least 10000rpm. If an unlucky egg is sucked in, it will be smashed into a paste immediately. Then a part of the minced meat is heated and gasified by the low-pressure compressor, the high-pressure compressor, the combustion chamber and the turbine, and discharged from the nozzle, and most of the rest enters the culvert and is discharged from the nozzle.

When designing the engine, there are requirements for foreign matter inhalation or blade fracture. It is very important that there should be no explosion and no debris flying out of the shell. At present, most engines have anti-foreign body inhalation devices. Once the inhalation of foreign objects is considered, the oil supply will be stopped.

Some people think that a protective net can be added, but there are too many problems with the protective net, which affect the intake efficiency, increase the resistance, have high cost, are difficult to maintain, and are unnecessary. Therefore, there is no protective net for the current aero-engine, and even if there is, the birds are probably cut into patties by the protective net in the bird swallowing test.
