Compared with their relatively unfamiliar pulse detonation engines, their company is more confident in this type of more traditional engines, and they believe that the potential of variable cycle engines in the future is also very large, and it is definitely possible. Based on the blueprint, developed, developed, designed and produced aerospace aircraft engines by themselves.

In this regard, X Aerospace Formula and Bald Eagle are looking forward to it very much. Of course, it is not a simple matter to develop an aerospace engine based on this variable cycle engine. According to the inference of their company's experts, it will take at least five to Ten years will do.

Therefore, according to the current situation, even if it is their aircraft, after the successful test flight, the variable cycle engine on this aerospace aircraft can only be used in the atmosphere. Outside the atmosphere, the pulse detonation rocket engine will still be used as the engine. power.

At this moment, after taxiing for nearly 3 kilometers, the huge plane finally pulled up its nose slowly.

Although the weight of this aerospace plane is very heavy, and the weight of fuel and other materials has reached four to five hundred tons, but because this aerospace plane is in the atmosphere, the engine used is the latest large thrust variable cycle engine developed by their company. The thrust of the engine in the atmosphere reaches more than 40 tons, so the ground sliding distance of this aerospace plane is obvious when it takes off, which is much shorter than the Phoenix series of Tiangong Technology.

However, after the plane took off, judging from the speed of the plane going away, it is obvious that the acceleration speed of this aerospace plane is far from being comparable to the Phoenix series of Tiangong Technology.

After all, it takes less than a minute for the Phoenix series to go from zero to Mach 1 when the engine outputs maximum power. Of course, the premise must be that the personnel in the aircraft can bear it.

However, the speed-up speed of this aerospace plane manufactured by X Space Company is significantly slower, and it takes at least 35 minutes to reach the speed of sound.

Although this aerospace plane is far from being able to compare with the Phoenix series in terms of speed up, the faces of the people at the airport, including their company's senior management and official personnel, are all full of smiles.

The successful take-off of the first flight of this aircraft has greatly boosted morale for them. A few minutes later, the aerospace plane successfully landed on the runway of the airport, and the ground staff and technicians on the ground naturally immediately appreciated the aerospace plane. The plane goes through a series of checks.

Because of the influence of the previous research and development of aerospace aircraft by Tiegong Technology, they are also planning to conduct a second test flight of this aerospace aircraft in three days, and they will not only conduct supersonic and supersonic test flights for this test flight.

Even in order to show the strength of their company, they are planning to conduct an exaggerated atmosphere flight three days later.

But the exaggerated atmospheric flight here does not mean that the plane is going to fly in space three days later,

Letting this aerospace plane enter the earth's low-earth orbit is just to let the aerospace plane fly out of the atmosphere at a supersonic speed, turn off the variable cycle engine of the aerospace plane, and at the same time not start the engine on the aerospace plane. Pulse engine, wait until the height of the aerospace plane reaches the limit, let it return to the atmosphere by itself, and finally start the engine and return to them.

The purpose of doing this is to test the state of the aerospace plane when it flies out of the atmosphere and re-enters the atmosphere, after all, for an aerospace plane.

Exit and re-entry. Data is very important.

Although their company has also purchased several Phoenix series aerospace planes from Tiangong Technology, and has driven these Phoenix series aerospace planes into and out of the atmosphere countless times, and has also recorded a large amount of data.

But these records are just the data records of Phoenix's series of soaring planes entering and exiting the atmosphere, and they do not serve as a reference for their aerospace plane. This type of aerospace plane is the data needed by a medium and large aerospace plane, so it is naturally different.

However, on the day X Aerospace Corporation rolled off the assembly line and successfully tested the flight, a large number of media in the world reported on it, saying that this was a breakthrough in the history of spaceflight in the world, saying that they had successfully broken the heavenly craft. Technology, the monopoly of aerospace aircraft engines, also broke the monopoly of Tiangong Technology in the manufacture of medium and large aerospace aircraft. In short, these news reported and exaggerated this matter. The defect was not mentioned at all, as if he didn't know about it at all.

Of course, not all reports praised the aerospace aircraft of X Aerospace Company. In fact, there are many media in the world who are not optimistic about the aerospace aircraft developed by X Aerospace Company.

Although before that, we used the pulse detonation rocket engine of Tiangong Technology and other space shuttle special accessories, such as the steering system of the aerospace plane, the control system of the aerospace plane, the telecommunication system of the aerospace plane, and so on.

It made the world's first breakthrough in the manufacture of aerospace aircraft from scratch, except for Tiangong Technology and Huaxia.

But in fact, X Space Company still doesn't know how to manufacture many parts of aerospace aircraft. Naturally, there will be many people who are not optimistic about this plane.

Some people even ridiculed their company, saying that their company has not even realized the ability to manufacture small aerospace aircraft completely independently.

It is completely idiotic to want to manufacture medium and large aerospace aircraft completely independently.

Of course, Wang Bing and Huaxia officials are naturally very concerned about X Aerospace Corporation, the first aerospace aircraft completely independently developed by their company.

At the same time, as the chief astronaut of Tiangong Technology, Zhao Feng, although he is already in the position number space station in the middle orbit of the earth at this time, he also saw relevant news from the broadcast system of the space station and the Internet, and communicated with the company to understand Details of this aerospace plane from Space X.

After reading the news and the company's data, Zhao Feng frowned at this time. As the chief astronaut of Tiangong Technology, he naturally knew that the successful test flight of an aerospace plane in the atmosphere does not mean that the aerospace plane will definitely be able to fly. Perform transatmospheric flights.

After all, flying in the atmosphere, X Aerospace and other aerospace companies in the world have rich experience in manufacturing aircraft in the atmosphere, including the manufacture of medium and large aircraft. Aircraft in the atmosphere, for example, with a volume comparable to 225, the design and manufacture of super-large aircraft are not a problem, but this is by no means applicable to the design and manufacture of aerospace aircraft.

As an experienced astronaut, he clearly knows how dangerous the next test flight is their space plane's transatmospheric flight.
