Because the manned aerospace aircraft must be equipped with a combined engine, the size of the aircraft is relatively large, almost the same size as a heavy bomber, so it must be very streamlined, otherwise the impact of air resistance on flight will be very large, and the flattening of the Shenlong fuselage belongs to the basic streamlined design.

Following the escalator into the boarding door, Xia Yu entered the belly of the plane, a bit like entering the cabin of a passenger plane. The design and layout of the cabin is similar to that of large aircraft such as early warning aircraft and electronic warfare aircraft, which are composed of various instruments, but it is relatively more streamlined, after all, the space is very limited.

Walking into the cockpit along the aisle, there are three fixed seats and two folding seats against the bulkhead, Xia Yu went to the captain's seat, felt the field of vision, and then observed the dashboard of the aircraft. Attitude gauges, rudders, throttles, and various displays that are still black because they are not powered on.

In terms of basic operation, the operation of this Shenlong manned aerospace aircraft is closer to that of a civil airliner, and perhaps a pilot who flies a heavy bomber is more suitable for flying the Shenlong than a fighter pilot, because after all, it is not a highly maneuverable aircraft, although this guy is far from being faster than a passenger plane and a bomber, and will eventually fly into outer space.

Leaving the cabin and coming to the ground, Xia Yu walked down the wings, although it belongs to the design of the large delta wing, but it is different from the angular triangle of the Phantom 2000, looking down from above, the front ends of the two wings of the Shenlong are streamlined, extending forward like water until the center of the nose, the whole plane looks very flat, very similar to the body posture of the devil ray, but the large flat wing part is only in the last third of the plane, which is closer to the space shuttle. Since there was no vertical tail, and the three air intakes were also on the back of the plane, Xia Yu couldn't climb up to see it up close, so he turned his head and walked towards the tail, intending to take a look at the engine.

As soon as he walked to the tail of the plane and raised his head, Xia Yu seemed to have been scorched on the outside and tender on the inside by ninety-nine eighty-one heavenly thunderbolts, full of black lines. After half a ring, he turned his head, looked at Yuan Limin with a smile on his face, and said, "Didn't you say that the No. 1 verification machine has been completed?" What about the engine? I didn't even have the engine to test the flight?! ”

Xia Yu was crazy, if an aircraft is not even loaded with engines, it means that this aircraft is basically in the design stage, or even in the static design stage, just to study the content of ground tests such as body counterweight, aerodynamic shape and avionics system. According to such a large project, if the aircraft in front of you is only a static design model machine, if you want to wait until the test flight, it will take at least five years.

You're not going to kill me, are you?!

Xia Yu was sweating profusely, if this is the case, he will immediately apply to be transferred back to the original unit, let alone fly the J-31, even if he only flies the trainer plane, at least he can fly in the sky! If you want to stay here, you won't want to fly in the sky within five years, and whether you can fly after five years depends on the progress of your research, and you have to rely on God's blessing.

"Rest assured." Yuan Limin seemed to be able to see Xia Yu's thoughts, and assured with a smile: "This is not a static model machine, the reason why the engine is not installed is because the power configuration is carried on the plane to do the ground interview operation stage abnormal resonance situation, we have been trying to solve this problem, so we will dismantle the engine unit, you see that there is no over there, that is the engine unit." ”

Looking in the direction of Yuan Limin's finger, a complete set of large engine units is fixed on a bracket, and it is roughly estimated that it is at least twelve or thirteen meters long and at least four or five meters wide, if it is not so exaggerated in height, it is almost comparable to a small room, such a big thing is actually the engine of the Shenzhou.

Following Yuan Limin to the engine group, Xia Yu said: "Abnormal resonance problem? What are the test results on a ground platform? ”

"No problems were found on the ground test platform, they were all in a normal state of vibration, and they couldn't be installed on the plane." Yuan Limin shook his head and said: "The engine runs well in the sub-combustion state, once the super-combustion is started to a power value, the resonance is very obvious, and it is obvious that the aircraft cannot be tested in the sky in this case." At first, we suspected that it was a problem with the main structure of the body, but after calculation, we didn't find any problems, and then we suspected that there was a problem with the power configuration combination, but then we found that the current configuration was the most suitable, and it didn't work if we made changes, so now we have a headache. ”

Speaking of this, Yuan Limin's eyes suddenly lit up, and he looked at Xia Yu with a sparkle and asked, "Do you have anything to build on?" ”

Xia Yu patted his head and sighed: "This is the first time I have seen this plane, how can you ask me to answer when there is no information?" Besides, you professional scientists haven't figured it out, how can I possibly know why? ”

Although Xia Yu's sigh is very reasonable, Yuan Limin believes very much in Xia Yu's knowledge level in the engine, and it is just to ask if there are any other ideas.

Don't have any information? It doesn't matter, there is it in the real yàn room. Yuan Limin couldn't wait to drag Xia Yu out of the workshop and get on the tram and drive in the direction of his real room.

Yuan Limin's real yàn room is not very large, or this is just one of his smaller real yàn rooms, as the general person in charge of the Shenzhou project, he has enough authority and ability to own several real yàn rooms at the same time.

After bringing Xia Yu into the real room, Yuan Limin turned on the computer monitor as soon as possible, and for convenience, his computer was turned on 24 hours a day unless necessary maintenance. After extracting a few of these materials, Yuan Limin asked Xia Yu to sit in front of the computer and said, "Anyway, it's still early, you can take a look at these materials here first, they are all about abnormal resonance." We'll have dinner together in the evening, and I'll introduce you to a few researchers from the power group by the way, so I'll give you a pick-up. ”

"That's embarrassing." Xia Yu was about to say a few polite words, but Yuan Limin immediately waved his hand, turned around and walked out the door, and said as he walked: "Don't be polite to me, I'll go find someone to help you send your luggage to the hotel now, you watch first, and we'll discuss it after I come back." Without waiting for Xia Yu's answer, he walked out of the room directly, leaving Xia Yu alone in the real room.

Xia Yu Khan, what kind of place is this? This is the real yàn room of the research institute with a high degree of secrecy! Breaking in at will can be regarded as a place for spies to sudden. I have a passable ID, but after all, it's just the first time I've come to this place, okay? If you meet someone you don't know, Old Yuan, is it okay for you to just throw me here? Xia Yu thought about it for a while, and his attention gradually focused on the information on the computer monitor.
