Chapter 168 (1/2)
There are two most important commissioning items for these ongoing verification commissioning, that is, water swallowing commissioning.
Water swallowing test run, as the name suggests, is to let the engine suck in a large amount of sand or water and other sundries during the operation of the engine, so as to develop the performance of the engine. Under such extreme conditions, the developed engine can withstand the test, whether it can operate stably, whether it will stop, etc.
At this time, on the No. 2 test bench, an engine has long been firmly fixed by the staff, and the engine has already been started.
In the control room of No. 2 test bench, Professor Dai and others were also staring at the data on the transparent screen in the control room.
Although the water swallowing verification has not started yet, the atmosphere in the control room is a little serious.
After all, the development and test run of swallowing water is a huge test for any engine.
Seeing that the engine has entered the cruise speed state, Professor poke said to the controller, ”it is possible to verify the swallowing of water!”
”Yes!” the controller replied, and he immediately pressed the button to swallow water.
Then Professor Zhang and others, through the huge transparent screen in the control room, can clearly see that at the air inlet of the engine, a certain water curtain begins to form, and countless water droplets are sucked into the air inlet under the strong suction of the air inlet.
After all, the engine speed has entered the rated speed, and the combustion chamber temperature inside the engine has reached as high as thousands of degrees. Although these water will not have a great impact on the engine blades like ice, if a large amount of water enters, However, it can reduce the temperature of combustion chamber and turbine, which affects the efficiency of engine.
However, the worry of Professor Zhang and others seems superfluous. Although it is said that many water droplets have been sucked into the engine at this time, it does not reduce the power of the engine. At the same time, according to the national data, the temperature inside the engine has not decreased, but the temperature inside the engine has increased slightly.
Professor Zhang knows that this is because the temperature and pressure inside the engine are too high, which leads to the rapid decomposition of these water vapor into hydrogen and oxygen under extreme high temperature and high pressure environment, and then rapid combustion again becomes the reason for water. The flame sprayed from the tail of the engine is no longer pure orange, But orange with a trace of blue, you can see.
”Increase the amount of water you swallow!” just then, Professor poke continued.
”Yes!” with Professor Zhang's order, the controller gradually increased the flow of jet water.
With the increase of water intake, the water sucked into the engine inlet naturally increases, and the original orange flame also begins to turn into light blue. Fortunately, there is no qualitative change in the internal temperature of the engine at this time, but it has returned to the original temperature.
However, there was no change on the professor's face, but continued to order the controller to increase the water swallowing until the output power of the engine and the temperature inside the engine changed.
