The test pilot Zhang Jun was fully armed. After boarding the plane, he brought a VR helmet and faced the lively crowd on the deck and took a few deep breaths.

As a high-end product, VR helmets are actually not able to be produced. Most of the parts are forced to be printed by the two 3D printers.

Although the production capacity of two 3D printers from Xia Wenming is not high, it is more than enough to deal with these high-end products. Anyway, people do not pursue large-scale mass production, even if the cost is a little higher, there is no big problem...

"I hope it can succeed." With such a major event, Lu Yiming naturally came to the test flight site to observe the flight situation.

He doesn't know how to fly a plane, he can only come here to be a spectator.

"If it succeeds, we will have experience in using anti-gravity engines." A relevant design expert seemed quite confident and took the initiative to find Lu Yiming to chat. "We are all a little worried that the performance of the aircraft is too good, which makes the pilot not used to flying."

"The performance is so good?" Lu Yiming asked with a smile.

"Yes, as the acceleration becomes larger, the flight speed will naturally become faster! The flight conditions are completely different from those of traditional aircraft. The anti-gravity engine has 42 tons of thrust, which can easily break through the speed of sound. In theory, in the atmosphere, it can easily reach 5 times the speed of sound, but this test flight, the upper limit of the speed is limited to 3.3 times the speed of sound."

The expert said with a proud look on his face.

The best plane that humans used to be, almost twice the speed of sound, but it combines the power of the entire country.

Such a small group of people have made better planes, and even with the help of Xia Wenming's technology, it is enough to be proud of itself.

"Fortunately, we humans are different from before. After strengthening our physical fitness, we can withstand greater strength and our nerve reaction speed will also be accelerated. Otherwise, we really can't fly such an aircraft."

"This is also..." Lu Yiming smiled and said: "This kind of anti-gravity engine was originally driven by artificial intelligence, and the computer's response speed is much faster than that of humans."

"By the way, why does Yuyan No. 1 still have a traditional aerodynamic layout? Shouldn't it be a UFO?"

The expert smiled bitterly: "Which is so easy to use the UFO? On the one hand, the traditional aerodynamic equation has been thoroughly understood and it is not easy to make mistakes. It only took us less than a year to get this plane. If we don't use the traditional layout, how can the new calculation time be enough? We don't even have a wind tunnel."

"On the other hand, when flying in the atmosphere, you still have to reduce friction, and the traditional aerodynamic layout is also good."

"If you run into space, you don't need streamlined aircraft."

Lu Yiming nodded. This is true. It takes ten years for a normal aircraft to go from research and development to production.

Now, such aircraft that have been processed in a few months must copy some of the previous technological crystals.

He asked again: "How many new aircraft are planned to be built?"

The expert thought for a while and said, "We have obtained a total of six anti-gravity engines, so six anti-gravity aircraft are at least. It is expected to build 4 fighters and 2 transport aircraft."

"Ordinary aircraft will also try to make some, such as helicopters. But... uh, the relevant funds have not been applied for. It is not impossible to make more ordinary aircraft, but the maintenance cost will increase greatly. Our Yunhai cannot afford to maintain too many aircraft."

Lu Yiming grabbed the hair on his temples and seemed a little helpless. Now humans have to study too much. The manufacturing of psychic shields accounts for half of the funding, and major research institutes are seeking for the other half of the funding, and no amount of resources can be allocated.

Even if these experts work overtime every day, it is hard for a good cook to cook without rice.

The expert poured a little bitterly for a while and returned to the original topic: "Some scholars also believe that the number of transport aircraft can be higher, but fighter aircraft is not that important. They want to build three anti-gravity transport aircraft and three fighter aircraft. In short, the two sides are still arguing."

"It's almost the same number, 6 anti-gravity aircraft. Other aircraft have similar manufacturing costs to anti-gravity aircraft, but the fuel price is too expensive and the maintenance cost is greatly increased, so it's all done to plan to get some cheap helicopters."

This is true. People cannot afford to support too many aircraft because it is not only the manufacturing cost, but also the maintenance cost.

If you don't maintain it and stay idle for a few months, these planes may be scrapped.

High-end jet aircraft require aviation fuel to start, and the flight cost is very high, and it takes about 1 ton of fuel to fly once.

When people are in Yanghe, where do they get so much fuel? If the oil they carry is consumed, they can only use plant fermentation to extract fuel, and the production capacity is very low.

The consumption of helicopters is lower, and at one time, it is almost two or three hundred kilograms of fuel, which is affordable to maintain.

Anti-gravity aircraft not only have high performance, but also have cheaper maintenance costs. It only requires electricity. Just install a large crystal energy battery to allow the aircraft to fly for a long time.

Lu Yiming looked at the design drawings of the anti-gravity transport aircraft. It looked a bit like a helicopter, with two large paddles above it, which is also the main transportation type in the future.

"The helicopter has better environmental adaptability and can work in complex environments. The effective load capacity of an anti-gravity transport aircraft can reach 60 tons!"

"The load capacity is 60 tons?" He was shocked.

In addition, the weight of its own weight is almost 100 tons, and it is one of the best large transport aircraft on earth.

"Yes, because this large transporter has two engines installed. In the design, this transporter cannot help but have an anti-gravity engine, as well as an ordinary turboshaft engine, that is, the propeller in the sky. The anti-gravity engine does not provide additional maneuverability, but is only used to offset the weight of the cargo, which gives an additional 40 tons of load capacity. Its speed is not high, about 400-500 kilometers per hour, which is almost enough anyway."

"So that's it." Lu Yiming nodded.

As a logistics unit, transport aircraft is actually quite important. For example, if it is necessary to land on an unknown continent, helicopters are more convenient, and fighter jets are useless; if a large number of people are in emergency shelter, transport aircraft is more quick.

With a load capacity of 60 tons, it can transport 1,000 people at once. 3 transport aircraft, 3,000 people at a time. In addition, some large emergency airboats can also carry people, and they can evacuate people in a few round trips.

The most important thing is that if you pick up large goods from the mainland, you have to rely on transport aircraft to transport them. For example, some large machines have a mass of 50 tons, and they cannot be pulled by manpower alone, and in the end they have to be lifted back by transport aircraft.

At present, there are not many helicopters combined with the Hope, so it is necessary to build new high-performance transport aircraft.

However, Lu Yiming did not participate in the topic of "manufacture of many fighter jets and transport aircraft". Professional matters should be solved by professionals. Isn't it a mistake for an outsider to command him?

Just chatting, the time for the test flight was up.

"take off!"

Under the order of the pictorial officer, the lights on the wings of the 20-meter-long plane flashed.

The anti-gravity engine is completely different from a normal jet engine. Its startup appears silent and without any sound.

But in just a moment, the plane took off vertically from the deck and rushed into the sky!

"Boom!" After the plane broke through the speed of sound, a sound barrier was generated, and the violent air flow formed a white umbrella at the position of the wings.

"Click!"

The reporters took photos wildly, and some onlookers also started to make a fuss.

"…This plane looks like a rocket! Will it fly too fast?"

"The vector engines in the past are just like that!"

"No, no, no, the anti-gravity engine is far superior to the vector engine. Both sides are not at the same level at all."

"Are we already surpassing the original Earth civilization?"

The plane flew higher and higher, it quickly became a small spot the size of a mosquito, and only some professional camera instruments could capture its traces.

"The navigation parameters are all normal, the current speed is Mach 3.1, Mach 3.2, Mach 3.3. The target speed is reached and it is decelerating!"

"The height is 12,000 meters, and it is continuing to rise to an altitude of more than 20,000 meters."

"The communication device is normal, the pilot is in good health!"

All these are good news.

As the plane continued to rise, the sound of friction with the air began to slowly decrease, but everyone's mood became louder and louder.

In theory, anti-gravity aircraft can fly directly into the universe!

Its working principle is completely different from that of a jet engine and can work normally in the universe...

But at present, there may be other horrors in the high altitude of the universe deep in the Yang River. In addition, the structure of the aircraft is not a spacecraft after all, and the radiation protection ability and life-saving devices are not enough to support humans' long-term survival in the universe. Therefore, the altitude of 50,000 meters is basically the limit of ascending.

If this limit is exceeded, there will be a safety mechanism, and the built-in artificial intelligence will stop the driver and then fly upwards.

"If you have the chance, you still have to explore the universe." Lu Yiming raised his head and thought in his heart.

After a while, the "rumbling" sound came again, the plane officially returned, and the cheers from people also seemed even louder.

Through the big screen, Yuyan No. 1 actually stayed at a height of one thousand meters, motionless like a helicopter!

This is definitely a miracle, a miracle triggered by the anti-gravity engine!

After a while, people saw that Yuyan No. 1 actually started flying upside down!

Even though it looks similar to a jet aircraft, the rear jet port only balances the fuselage and maintains the aerodynamic layout, and does not spray at all, so it is possible to fly backwards.

The so-called test flight is not an acrobatic performance, but a consideration of all the situations of the plane and finding the flaws. But in ordinary people, it is no different from showing off skills.

The test flight was completed in about half an hour, and there was no big mistake in the eyes of ordinary audiences. However, under the observation of all weapons experts, there are still many things that can be improved.

"Well, the shape of fighter jets in the past was still a bit inappropriate." A scientist said, touching his chin.
