Chapter 789: Start the engine
General Lin nodded: "To develop a fighter, we must act in accordance with scientific laws, and if we don't talk about science, there will definitely be problems." ”
This is a very serious process, a process of scientific exploration, and General Lin is also very concerned about it.
A newly developed fighter plane, all parts are new, it is impossible not to have problems, the process of test flight, is to constantly discover and solve these problems, and finally make it mature, this process is destined to be very long.
"What are you going to do today?" General Lin asked Qin Feng.
This ceremony is over, and when the fighter plane is pushed into the hangar, it means that it can be released at any time, so what should I do next?
"Test drive." Qin Feng said: "After entering the hangar, there will be technicians to fill the plane with fuel, the whole machine will be energized, various lubrication pumps will be turned on, and then the engine will be started!" ”
Any flight, first to turn on the engine, today's first experiment, is to turn on the engine, as long as the engine can turn up, all parts work normally, it means that the installation of the engine is no problem.
The experiment of the J-8 fighter back then was a problem when the engine was started, and as a result, the entire fighter burned out, will there be a similar failure now?
Probably not, because this engine is a fully fledged engine, it has been flying on the Su-27 for tens of thousands of hours, and there has been no accident of ignition and burning, even if the receiver is changed to it, it is not a big problem.
Engine test runs are dangerous, for example, if you stand near the air intake, you may be sucked in, and when you come out, you will be dusted, which is quite scary.
Therefore, everyone can only stand outside the hangar, watching the busyness of the technicians inside, the first thing is to fill the fuel, the first fighter plane leaving the factory, the internal pipes are empty, the fuel car started to the side, began to fill the fuel, only 500 kilograms were filled, enough for the first test flight.
Then there is the pump oil, let the fuel flow down the oil pipeline to the back, if there is air in the pipeline, it will cause unstable operation, the technician in accordance with the operating procedures, proficient pumping oil, complete all the tasks before the commissioning.
"Power cart!"
Now, it was the turn of the power supply car, and the thick cable was connected to the fuselage, and Song Lao beckoned in the crowd: "Qin Feng, are you coming?" ”
Although there is a ground power supply car, but if you want to start the engine, you still need someone to operate it in the cabin, hearing Song Lao's greeting, Qin Feng immediately trotted all the way, followed the gangway, and climbed onto the cockpit.
The first step is to open the electric door!
I've only seen it in a simulated cockpit before, but today it's the first time I've operated it in a real cockpit, and after he turned on the main door switch, the color display on the right side of the three monitors in front of him lit up first, and various system activation information appeared.
The cockpit with a flat and three-lower layout is full of modernity, which is definitely much better than the Su-27 fighter!
Qin Feng looked at the monitor in front of him with relish, almost on a line, only the middle one was slightly lower, the display screen on the left mainly showed the weapon plug-in, this is a weapon control system interface, and the middle one, mainly showing the electronic map and target tracking, can also be used as a radar tracking control interface, these two screens are black and white screens, today because it is only a test run, so these two screens are not turned on, and now they are still in a black screen state.
The screen on the right belongs to the status display of the aircraft, which can display various information of the aircraft, including the heading of the voyage, the slope and so on, the navigation information, etc., and also includes the control system interface of the entire aircraft.
Of course, this is not fixed, when needed, you can switch the screen at any time, and you can also display the information of the screen on the heads-up display, after all, the head-up display looks the most convenient, so it has reached the world's leading level.
Of course, under the display screen, there are some mechanical pointer instruments, which is to take care of the habits of many pilots, but also in case there is a problem with the display system, there can be basic mechanical instruments to ensure the safety of the flight, for many old pilots, it is very kind to see these instruments, they are not used to the display.
Qin Feng glanced at it, and he was able to take in all these instruments, and the upper left corner was the pilot clock; The middle is mainly the display of flight attitude, including horizon, speedometer, altimeter, side slip meter, side slip meter; Below is the engine's, including tachometer, thermometer, oil pressure gauge, etc.
At this time, the electric door opened, the display was normal, Qin Feng toggled the engine start switch, and the familiar howl of the starter came from the tail.
The start of the turbine is similar to the start of the car, which is driven by the motor, and the turbine begins to rotate under the drive of the motor, and the turbofan blades of the third uncle's engine rotate faster and faster, emitting a unique howling.
The car starts in a few seconds, but the engine starts for a minute, which is already fast.
Qin Feng stared at the engine tachometer, the speed was getting faster and faster, faster and faster, when the speed reached tens of thousands of revolutions, puffs of black smoke came out of the tail, and fuel began to be injected in the combustion chamber!
With the combustion of fuel, it can drive the turbine rotation of the tail, and then drive the compressor in front, and after gradually stabilizing, the drive motor is separated, the engine finally runs smoothly, the smoke in the tail also disappears, and the engine starts normally, in a slow state!
That's right, for the turbine, the speed reaches 10,000 rpm, it is only a slow state, and the throttle lever at this time is also in the front position, in the cockpit, Qin Feng's heart is surging, this is the fighter, it is the most advanced fighter in the world!
The simulated cockpit, which has always been simulated, has no real cockpit feeling at all, and now, the engine in the tail is roaring, and the whole plane is shaking, as if it can spread its wings at any time.
Of course, Qin Feng couldn't do other actions, but he couldn't let go of the brakes and go directly to the runway, he reported loudly: "The engine starts normally!" All kinds of gauges are displayed normally! ”
As long as he glanced, he could see those mechanical instruments clearly, and at the same time, the color display could also show green, which means normal, if there is an abnormality, it is a flashing red light.
"Thirty throttle openings!"
"Understood!"
Qin Feng slowly pulled the throttle lever backwards, maintaining it to the thirty percent position, and the roar of the tail became more intense.
