Chapter 1368 Vector Engine

Previous page        Return to Catalog        Next page

    No wonder this troop leader has such an attitude.

    You must know that the speed of Mach 1.8 is not just the engine relative to the air. The air is also Mach 1.8 compared to the engine. That is a pure speed of Mach 1.8. At this level, even the gentle air is a sharp knife. Not only  Sharp, and accompanied by extremely high friction heat energy.

    That¡¯s all. The key lies in the high-altitude environment of 15,000 meters.

    You must know that it takes a lot of effort to start an aircraft engine on a snowy plateau, and it can only fly at the cost of a sharp decrease in performance. The reason for this is that the altitude of the snowy plateau is too high and the oxygen content in the air is too low.  There is no way to fully burn the aviation fuel in the aircraft engine.

    The average altitude of the snow plateau is 4,000 meters, let alone 15,000 meters, which is more than three times the average altitude of the snow plateau. However, the oxygen content does not decrease by three times accordingly.  times, but dropped exponentially several times.

    Under such circumstances, it is difficult for an aerospace engine that requires a large amount of oxygen to support combustion to obtain sufficient combustion catalysts, and restarting is out of the question.

    ¡° Nowadays, the combination of supersonic speed and the environment at an altitude of 10,000 meters is equivalent to the ultimate move meeting the ultimate move. The damage is not only doubled, but even tens of thousands of times.

    This is also the reason why most second-generation and third-generation aircraft equipped in the world today invariably choose to descend when an engine shutdown accident occurs at high altitude.

    Because the only way is to lower the altitude, obtain sufficient oxygen and reduce the speed to reduce the air speed to ensure that the engine can be restarted in a stable environment. Otherwise, you will either parachute quickly or die with the plane.

    At this moment, the wd-64vip aero engine located in the No. 1 cabin actually wants to challenge what is called a restricted area in the domestic aviation industry. Even if he is not flying in the sky with a real aircraft, the head of the army is still in the No. 1 high-altitude simulation experimental cabin.  The engine was sweating.

    This is not only the case for the commander of the unit, but also for other commanders and leaders. Even those who are not very clear about the inner tunnels all looked solemn after listening to the introduction by knowledgeable people and stared at the live LCD screen of Cabin No. 1.  His eyes were filled with unspeakable tension.

    "Cabin No. 1, the speed is Mach 1.8, the temperature is minus 50 degrees Celsius, the air pressure is 12 kilopascals, the air flow is 742 kilograms per second, everything is normal in the test machine"

    While all the army chiefs and leaders were paying attention to every move of the aircraft engine spraying high-temperature airflow on the screen, at the command seat in the control hall, the young commander quickly reported a set of data and paused.  , and then said without hesitation: "Keep the cabin environment unchanged and prepare for the countdown to stop 10, 9, 8 3, 2, 1, 0 stop!"

    After the order was given, the operator in the front row immediately pressed the stop button, and the wd-64vip aircraft engine that was roaring and galloping a second ago on the screen instantly misfired.

    However, the engine has stopped working, but the environment in the No. 1 simulation experimental cabin has not changed at all. The high-speed airflow, low-temperature environment, and lack of oxygen are all present. Even through the LCD screen, many people present  The army chiefs and leaders can all feel the situation of the wd-64vip aero engine in the simulation experimental cabin, and its condition must be extremely bad.

    But in such an environment, the test console did not immediately issue a start command. The reason is very simple. The countdown display in front of the control hall only counted 52 seconds.

    Yes, the high-altitude restart test here does not restart immediately after shutting down, but with an interval of one minute. In the suffocating atmosphere just now, time only moved forward for a mere 8 seconds.

    "Xiaozhuang, how confident are you this time?"

    Finally, the head of the headquarters couldn¡¯t hold himself any longer and asked Zhuang Jianye next to him.

    Zhuang Jianye shook his head: "It's hard to say, but this is also the last high-altitude restart test of our wd-64vip aero engine. If it passes this time, it will prove that our variable cycle system has withstood the test. After all, no matter when,  One minute is enough for the pilot to do a lot of things. If it exceeds one minute, according to our theoretical calculations, the aircraft will soon enter a spiral speed state. Unless it is a high-thrust vector engine, it will not be able to change it. wd-64vip Aviation  The engine currently does not have the capability of multi-directional vectoring, and the thrust also needs to be improved, so we are preparing to conduct the high-altitude restart test of more than 1 minute after the wd-64vip aeroengine completes the second and third phases of improvements."

    After hearing what Zhuang Jianye said, the head of the headquarters almost grabbed Zhuang Jianye's collar and sprayed: "Is this what I want to hear? I'm asking how sure you are, you actually pretended to be 13, Zhuang Jianye didn't pretend to be 13  He could die!"

    But the head of the headquarters can complain about this in his stomach, or even meet alone in privateIt was an angry rebuke, but in front of everyone, even the head of the headquarters had to suppress the evil fire in his heart, nodded calmly, and said: "I understand!"

    The problem is that the head of the headquarters knows what is going on, and Zhuang Jianye, the instigator, has nothing to say, but how do the other people present know?  I heard that China Takeoff will carry out the second or even third phase of improvements based on the wd-64vip aero engine.

    The direction is to increase thrust and install an omnidirectional thrust vector device. You must know that any of these two items are at the forefront of today's aero engines.

    In particular, the omnidirectional vector device is a standard feature of the next generation of combat aircraft, because in addition to the unparalleled aerodynamic shape of the so-called super maneuverable engine, the vector device of the engine also plays an important and irreplaceable role. Because of this, even thinking about it in the past  Super-maneuvering maneuvers that no one even dares to imagine can be easily accomplished by an aircraft.

    ¡°The Pugachev Cobra maneuver that made the Su-27 dominate the world was an ordinary maneuver in front of an aircraft equipped with a vector engine.

    Because of this, many people showed a hint of excitement after listening to Zhuang Jianye¡¯s words, and asked about the timetable for the next stage of improvement of the wd-64vip aviation engine.

    Zhuang Jianye responded very modestly: "The specifics depend on the progress of our wd-64vip aero engine basic prototype. After all, our wd-64vip aero engine uses a more advanced variable cycle system, let alone in China.  , it is also at the leading level internationally, but because of this, there are no precedents for many standards and norms to learn from. We can only rely on our little exploration and accumulation to get through this difficult road before we can talk about the next stage.   Oops, look I'm just saying here, the time to start is coming. This test is very critical. If it succeeds, everything will be easy. If it fails, we will have to make major changes"

    It was too late to say that, but soon, Zhuang Jianye accidentally pretended to be 13, and time passed. Before Zhuang Jianye could finish his words, the commander on the command seat said loudly: "Start!"

    As soon as he finished speaking, the controller pressed the start button. The wd-64vip aircraft engine on the screen, whose outer surface had been covered with a layer of frost by the low temperature of minus 50 degrees Celsius, suddenly shook, and then the fan that seemed to be frozen began to slow down.  It rotated faster and faster, and finally with an unwilling roar, the entire engine was like a beast that came to life, spitting out flames again

    Restart successful!
