Aircraft overhaul has made almost three years, since that is fairly familiar with the aircraft structure. The main question on the subject, the aircraft landing gear wheels that part of the call. As the name suggests, landing gear, with only about landing, landing gear means no power, only in the main landing gear brakes, no brakes front landing gear, nose gear steering control when taxiing. Powered aircraft engine alone. Most of us see the aircraft engines are turbofan engines, turbine engines are equipped with all three parts of the compressor, combustor, turbine, turbofan engine has a propeller in front of the compressor, is what we see engine inside the fan. Engine speed is low, in front of the suction is not strong, standing in front of two to three meters away from the engine will not be sucked in, but enough to push the aircraft forward momentum.
Compared to the turbofan engine, propeller suction smaller.
Do not underestimate the small aircraft, small aircraft, "Boeing 737-300" This small aircraft fifty tons, can into space more than fifty tons of airplane, you think about how big the engine thrust
Now each side of the engine has a warning sign, as shown in Figure
Command of the aircraft at least to stand in front of the front landing gear, plus the pilot can see, it would be more forward, and there is absolutely secure areas. Our aircraft engine running when I always stay in the front landing gear position.
And then told again, do not underestimate the engine suction, below is a container being inhaled engine (people sucked into the engine of the image is too bloody, not here on the picture).
The figure is the moment when the compressor pressure vapor is sucked into the engine:
The above three figures show whether the phenomenon is amazing? You can click on the following links, continue to browse relevant big picture:

Why water vapor is sucked into the engine, similar to a tornado will form one line? Stay tuned for "Know Daily", we will try to invite experts, students were easy to understand explanations (Editor's note).
