Chapter 412: Takeoff and Landing
The start of an aircraft engine is complicated.
The engine can't spin on its own, even if it is injected directly into the combustion chamber, it can't form enough gas to push the turbine and then drive the compressor in front.
Therefore, the engine has to rely on the outside energy to let the engine spin first.
This kind of energy, for fighters, is mainly provided by ground power vehicles, after all, fighters are quite important to their own weight, the lighter their weight, the better, and for transport aircraft, there is no such concern, a transport aircraft with a total take-off weight of several hundred tons, do you still care about an auxiliary power system?
This auxiliary power unit, called the APU, is installed on the transport aircraft, so the transport aircraft can be activated completely by its own ability.
Now, Jenny's hand rests on the APU's switch, activating the auxiliary power unit.
The noise is not loud, except for a slight tremor, nothing else, and the activation of this auxiliary power unit can already provide a steady stream of electricity and compressed air.
Then, Jenny put her finger on the control knob of the engine to the ignition start, and the main electric door was raised, so that the engine had received the start signal and the fuel supply channel was opened.
Then, the gas provided by the APU is quickly blown towards the starter, and this air pressure must be high enough, and almost every engine starts at full speed of the APU.
The starter starts to rotate, and the N2 rotor of the engine is driven by the accessory gearbox and transmission gearbox of the engine, and it begins to accelerate and rotate.
At this time, the engine under the wing began to emit the characteristic whistling of the turbine and began to spin!
Soon, the engine's tachometer and pointer began to turn, and when the speed was reached, the tail of the engine suddenly burst into flames, and a circle of fuel nozzles around the combustion chamber began to inject fuel, and the combustion chamber began to work!
At this point, the engine speed continued to increase, and as the roar intensified, the starter and engine were separated.
"Engine No. 1 started normally and is now slow." Jenny said quietly.
At this time, Nathan realized that Jenny was also a veteran, and her commercial aircraft license was not just as simple as having just taken the exam!
"You've ever flown a big plane?" Nathan couldn't help but ask.
Since you're a veteran, you don't have to worry about it.
"I've flown a few Boeing 707s." Jenny said, "It's our family's own. ”
Okay, it turns out that the big family of the family all owns private jets, or the Boeing 707 level, Nathan put down the flight manual, since this is the case, what are you afraid of.
"All four engines have been started." Jenny said.
"The Lone Ranger calls Delta, the Lone Ranger calls Delta, ready for take-off and landing flight training, ask for approval." Nathan said into the radio.
Just now, I said that for the first time, I would run first, and now, since Jenny has flown over the Boeing 707, what are you waiting for, just go straight to the sky.
"Delta received, can carry out take-off and landing flight training."
For this kind of large transport aircraft, the consumption of fuel is quite terrible when taking off and landing, and the most difficult thing to operate an aircraft is to take off and land, so they mainly carry out take-off and landing training.
Like now.
"Roger." Jenny answered, and began to gently pull the throttle levers back on the four engines and release the brakes.
The huge C-5 transport plane began to glide slowly on the runway, although the engine power is quite strong, but due to the large weight of the aircraft and the bloated shape, the acceleration ability of this aircraft is very poor.
From Nathan's point of view, there is not even a sense of pushing back.
The transport plane accelerated slowly, Nathan watched the scenery change outside the window, and then turned his head to look at Jenny, at this time, Jenny's expression was very serious, this look, it looked very attractive.
The sun shines through the window, and when you look at Jenny's lines from the side, it is so beautiful, and she is still so charming and lovely.
Jenny has already started to pull the dial back.
Ordinary fighters, that is the operating stick, is between the legs, and transport aircraft, almost always have a wide operating disc, with both hands held on it, slowly pulled back.
The nose of the C-5 transport plane began to lift upward, the front wheels were off the ground, and the four engines were still pushing the transport plane forward, and it flew for more than ten seconds, and finally, the bloated body was light, and it flew!
Generally speaking, the captain controls the high-risk occasions such as take-off and landing, but now, Nathan is looking at Jenny, letting Jenny operate it alone, and if there is a problem, he will take over again.
And this take-off is quite perfect, relying on the unique gentleness of women, her movements are very slow, and the huge transport plane is like a diligent old scalper, hard work.
"Four turns, ready to enter the landing course." Nathan said.
Of course, Nathan knows this kind of transport plane, once the engine starts, drinking oil is like drinking water, cooing, or saving a little.
In the initial training of pilots, after taking off, around the airport, turning four turns, you can re-align the runway, at this time, in the wide cabin, Nathan looked out, looked at the white clouds in front of him, and somehow, remembered the days when he used to fly a blackbird.
This flight career of mine is really colorful, flying passenger planes, flying F4, flying Tomcats, flying Blackbirds, and now flying C-5.
If it weren't for that opponent, his crossing should be bland, right?
Nathan thought of his opponent again, because of the existence of this opponent, his crossing became so exciting, of course, the current incident has nothing to do with that opponent, and he definitely can't interfere.
Even if he intervened, it was only for the historical Eagle Claw operation, and it was absolutely impossible for him to know his current plan, and as a later traverser, he was prophetic.
That's my biggest strength.
"Already in the four turns, ready to land." Jenny's voice came from her ears.
Nathan looked up, and he could already see the runway in the distance.
"Well, it's up to you to land." Nathan said, "Steady, just like usual." ”
Compared with take-off, landing is more difficult, the slightest carelessness, even a little bit of attitude, may destroy the plane and kill people, which must go through long-term training.
Despite Nathan's words, his hands were on the control panel, and if Jenny had a problem with the operation, Nathan immediately took over control.
