With the advent of summer, heavy rain and light rain will take turns in various places. Passengers traveling in the rainy season will definitely worry: Is the plane taking off in rainy days safe? Is it dangerous for rain to enter the engine? In fact, you can rest assured that the aircraft engine can withstand most of the rain. Xiaobian today to talk about those things about the aircraft engine. high precision customized welding manufacturers
1 What is the principle of an aircraft engine?
Today’s common aircraft engines are mainly divided into: turboprop engine, turbojet engine and turbofan engine. Most civil aviation aircraft use turbofan engines. From a structural point of view, a turbofan engine includes a fan, a compressor, a combustion chamber, and a turbine.
The front-end fan will suck in the external air, and the air will be divided into two paths internally: one path of “Senma” is directly ejected through the external duct, generating a large amount of thrust to the aircraft; , enter the combustion chamber and combine with the fuel to form a continuous combustion of the oil-gas mixture to generate thrust. high precision customized welding manufacturers
Since it takes less energy to drive a larger fan, which means that a larger fan can get more extra power when consuming the same amount of fuel, the larger the proportion of external ducts, the more efficient the engine is . Turbofan engines have also become the most commonly used engines for civil aviation aircraft.
2 Will the aircraft engine enter the water?
The editor can definitely answer you: Yes! But water ingress does not necessarily damage the aircraft engine. Because the air entering the engine will enter the inner and outer ducts separately, the rain/moisture in the air is actually the same.
There is a diversion groove on the inner wall of the engine, and the rainwater is discharged through the outer duct, and basically cannot enter the interior of the engine. And the rainwater entering the inner channel is not to be feared, because the temperature of the combustion chamber is quite high (about 1400-1700 ℃), a small amount of water in the air will evaporate instantly in the compressor and combustion chamber.
However, if the flight encounters a heavy rainstorm or enters a cumulonimbus cloud, the engine may absorb a lot of rain, causing the combustion chamber gas temperature to drop, the combustion chamber needs to consume more fuel, which may lead to engine damage. Therefore, when there is a heavy rainstorm, the take-off and landing time of the flight is usually adjusted.
3 How to avoid water in the aircraft engine?
You don’t have to worry about water ingress. When the aircraft engine leaves the factory, it must pass a strict water swallowing test to verify whether the water inhaled by the aircraft intake will affect the stable operation of the engine. high precision customized welding manufacturers
A large number of nozzles are placed in front, which sprays 800 gallons (about 3 tons) of water per minute, and the aircraft engine is required not to be extinguished.
In addition, flight captains and airport air traffic controllers can also use weather radar to learn about dangerous clouds in advance, reduce the time spent in clouds with high water content, or try to avoid them within a reasonable range.
In fact, severe weather such as hail and thunderstorms affects flight safety more than rainy days. If you encounter flight delays caused by weather, I hope everyone can understand the arrangements of the airport. After all, this is for the sake of everyone’s flight safety. high precision customized welding manufacturers
