Rebirth of the 1980s: The Military Industry Empire

Yu Ximing was immediately stunned.

With the technical strength of the East, it would be good enough to develop an aircraft with two wings attached to the fuselage. The 611 Institute has the strongest technical strength. The J-10, with its canard layout, also didn't use leading-edge vortex controllers. The boundary between the fuselage and the wing was still clearly defined. Leading-edge vortex controller technology is the most advanced technology in the West. Only the first-tier Old Maozi and Americans have this kind of design capability.

Qin Yang actually proposed installing leading-edge vortex controllers, and what's more, installing the leading-edge vortex controllers in front of the tail! This is definitely the first of its kind in the world!

Yu Ximing couldn't imagine that there would be such a design method, but obviously, Qin Yang didn't seem to be lying. After all, President Qin has already created many miracles, so there is only one possibility: this design that President Qin is talking about may really work!

"Okay, President Qin, I will remember these designs you mentioned," Yu Ximing nodded.

As long as President Qin says it will work, then it definitely will!

A few days later, the T-45 trainer was delivered, along with several American technical experts, led by Thomas. However, they were not satisfied with this desperate measure.

"If it weren't for the company's arrangement, we wouldn't have come. We also don't believe that you can solve this problem for us. This is a difficult problem that has stumped all engineers," Thomas said.

"Mr. Thomas, if you are not satisfied with our technology, you can go back immediately. We are thinking of you, and you are still talking nonsense here," Qin Yang said with a gloomy face.

Anyway, the JJ-7 has already been modified. If this one doesn't work, we can still use the Hai Shan Eagle. These arrogant guys must know that we will not allow ourselves to be looked down upon.

"Okay, let's go then." Thomas was also unambiguous, and planned to leave with his subordinates, just treating it as a one-day tour of the East. They didn't have any good feelings about this kind of place, anyway, it wasn't a big city like Magic City.

However, at this moment, a strangely shaped aircraft taxied onto the runway. They all widened their eyes. What kind of aircraft is this? It has never been seen anywhere in the world!

The nose is small, and the cockpit is very close to the nose, low in the front and high in the back, the standard layout of a trainer aircraft. The air intakes on both sides are stuck under the cockpit, looking full of modernity, but looking at the back, the high back, the tall vertical tail, the familiar shape, this is a J-7.

The J-7 can actually be modified into this shape?

"What kind of aircraft is this?" Thomas asked.

"JJ-7," Qin Yang said, "The most advanced trainer aircraft produced in our East."

JJ-7, only one word different from J-7, which means that this aircraft should be improved on the basis of the J-7, but can the J-7, that is, the MiG-21, be modified like this?

Changing the nose intake to side intakes requires a lot of experiments and countless wind tunnel tests to determine. The entire nose structure frame needs to be redesigned, and the cockpit is also brand new. It can be said that this workload is not much less than designing a brand new aircraft.

The fact that the Easterners can complete the development of this aircraft shows that they already have a certain foundation in aircraft design, especially in trainer aircraft. And their trainer aircraft has encountered problems again, so they might as well ask them for help.

"President Qin, I take back what I just said. I hope you can help us find the fault in the aircraft," Thomas said.

Qin Yang smiled and said, "Okay, let's start with the test flight. Your pilot sits in the rear cockpit, and our pilot sits in the front cockpit. Let's fly this aircraft first and feel its performance."

"Okay."

This is also a normal requirement.

"Can you speak English?"

"Of course."

Hearing this proficient answer, George breathed a sigh of relief. During the flight, the most taboo thing is that the communication between the front and rear cockpits is not smooth. If ground personnel are needed to translate, it will undoubtedly delay time. Now that direct communication is possible, that is the best choice.

"Okay, then we will do basic flight now. You will fly, and you can take off when you accelerate to two hundred."

The Americans are really bold. Lei Zi has just come into contact with it, and he actually wants Lei Zi to fly, and he doesn't even introduce the cockpit instruments.

However, whether it is American or Soviet, the various instruments are similar, only the positions are different. In fact, in the glass cockpit of later generations, the operation became complicated. If you want to find a certain function, you have to memorize it and see which menu it is in, and you may have to flip through several levels to find it.

Now, since the Americans let him fly, Lei Zi is also unambiguous, skillfully toggling the switches, starting the engine, and then gently sliding onto the runway.

At this time, the JJ-7 had already taken off, and the runway was empty. After Lei Zi called the tower, he fully opened the throttle and accelerated on the runway, and then gently pulled it up.

The thrust-to-weight ratio of the T-45 trainer is not high. It is equipped with 1 F405-RR-401 turbofan engine with a thrust of only 26 kN and a maximum takeoff weight of 5.7 tons. Calculated, the thrust-to-weight ratio is less than 0.5, but this subsonic aircraft is very flexible. As soon as it accelerates to two hundred, the fuselage can be easily pulled up.

Lei Zi also sighed that the American aircraft is still very good. It is a pity that we don't have similar engines, otherwise we can also build similar aircraft, but President Qin will definitely have a way.

The trainer aircraft began to climb and drilled into the sea of clouds.

Even if it is moved to the provincial capital, it is still a backward place, unlike the big cities on the coast. After taking off, the surrounding area is the scenery of the Yunnan-Guizhou Plateau. George looked at the mountains below, feeling a little irritable. He also didn't believe that the Easterners could solve this problem. Are there aircraft designers in the East? No!

After watching for a long time, he looked at the cockpit instruments again, and saw one of the lights lit up, and his face changed instantly.

"Lei Zi, you didn't calibrate the inertial navigation system before takeoff!"

"What is inertial navigation?"

For Western aircraft, inertial navigation is a common subsystem. There is a gyroscope inside that continuously and stably rotates, and there are three-axis accelerometers next to it to measure various deviations, and then accumulate them, so that you can know all the trajectories of the aircraft after takeoff, forward, turning, etc., so you can know where you are.

However, the laser gyroscope needs to be calibrated before takeoff. This is just a very common operation, but this Eastern man didn't do it.

Because Eastern aircraft don't have this kind of thing.
