Chapter 631： Jet's first flight

While the whole world was talking about Edel's ascension to the Bulgarian throne, a group of people in blue overalls were busy in front of a weird-looking plane in a heavily guarded air base outside Lviv.

To say that this aircraft is weird is because it does not even have the most basic propellers, and there is no propeller installed on the outside of the aircraft.

Such a weird-looking aircraft also attracted the attention of many air force base personnel.

"Dolloff, do you think this thing can fly?"

In the crowd of onlookers, a base staff wearing a flight jacket asked his colleagues around him.

The called Dolev replied with a shrug and a look that you don't come to ask me. "Who knows this. But I heard that this is the latest result of the Lviv branch of the Power Research Institute, and it may be able to fly."

After speaking, Dollef continued to say something. "But if I were to fly, I wouldn't dare."

That's right, with this weird-looking airplane, Doleff was not at all relieved. Even if he is known for his boldness in the Fourth Aviation Wing, he still refuses to try an airplane like this without a propeller.

There are a lot of people like him in the base, and the focus of everyone's discussion is whether this thing can fly. And such comments will inevitably reach the ears of the staff who are busy in front of this weird plane. Faced with these discussions, Valksu, as the project leader, was not surprised at all.

Valksu is the head of the jet engine project at the Power Research and Development Center. He graduated from the Department of Power Engineering of the University of Bucharest and was recruited by the National Power Laboratory with his outstanding results. After working in the power laboratory for several years, Valksu developed a keen interest in jet engines.

In fact, the development of jet aerodynamics was very early. Since the 17th century, some people have tried to use steam power or internal combustion engines to achieve usable jet engines, such as the Dutch physicist Huygens.

Henry Coanda also experimented with jet aircraft as early as 1910. The method was to use a conventional piston engine to drive a fan to compress air and ignite the gas propelled in the space behind. This was called a thermal jet engine. Although this engine has a simple structure, it has a large weight, insufficient thrust, and poor practicability.

Of course, the development of jet engines did not end with failure, but continued to develop.

Albert Von of the Austro-Hungarian Empire designed a device that used gas and compressed air to increase the range of cannonballs in 1915. This device compresses and ignites the airflow of the projectile during high-speed flight through a variable cross-section air inlet, thereby providing thrust.

However, the Austro-Hungarian army finally did not adopt its design, so he registered the patent for supersonic ramjet in Germany in 1928 and passed it in 1932. The ramjet was born.

In 1921, Frenchman Maxime Guillaume obtained the first patent for a jet engine. His design is similar to an axial jet engine.

In 1928, Frank Whittle of the Royal Air Force Academy in Cromwell proposed a new jet engine design. In January 1930, Whittle filed a design patent for the jet engine and obtained the patent in 1932. Whittle’s design is to install a two-stage axial compressor in front of a large centrifugal compressor and driven by a turbine. Later Whittle removed the front axial compressor and used a larger centrifugal compressor.

Since jet engines continue to develop abroad, it is impossible for the National Power Laboratory to turn a blind eye to Romania as the main power research unit. With the support of the veteran Dean Rudolf Diesel, the National Power Laboratory is also developing a jet engine.

It needs to be explained here that Rudolf Diesel no longer continues to develop diesel engines. Now in his seventies, he has already become famous with the widespread use of diesel engines. At present, his main disciples continue to develop this diesel engine.

The research and development of jet engines is in the hands of Valksu, who has the most research on jets in the power laboratory. The Valksu did not disappoint, and finally succeeded in the development of a new jet engine in cooperation with his German colleague Hans von O'an (the result of the Rhodes cooperation).

During ground testing, this axial-flow jet engine produced a thrust of 5 kilonewtons, which surprised researchers from the two countries. This means that this jet engine has reached the standard of use. Since it has reached the practical standard, it is simply too uncomfortable not to fly.

Therefore, under the impetus of Valksu, a new aircraft specially designed for flight test of this engine was born. This new aircraft, labelled F-101, has a total length of 9.4 meters and a single wing. Because the engine is in the abdomen, it looks a bit like an inflated puffer fish, without the slenderness of other propeller aircraft.

This is also the reason why most people in the base don't like it. The appearance is really important for the aircraft.

But this is not so important for Valksu and Hans von O'an today. First of all, they have to make this aircraft fly.

"How is the inspection?"

Some Valksu, with sweaty palms, asked his staff. This is the last check before the flight. If the plane can't fly, you can't make a deal. It should be understood that the power laboratory not only develops jet engines, but the traditional piston engine power laboratory alone is developing several models. Such as the 900-horsepower star air-cooled engine, the 1200-horsepower straight-cylinder liquid-cooled engine, and the 1,350-horsepower V-type liquid-cooled engine, it can be said that there are many kinds of aviation engines alone.

Even many projects not only pay attention to their own work, but also take advantage of the opportunity to make preparations for the next step in advance. For example, he knows that the 900-horsepower star air-cooled engine project in charge of Krishid is doing preliminary research for the next 1,200-horsepower.

Not to mention gasoline and diesel engines, which are currently the leading products of Power Lab. These two engines rely on the prosperous automobile industry and Rudolf Diesel's outstanding capabilities respectively, and also allow the power laboratory to obtain sufficient funds. Although funding is sufficient, competition is indispensable. Everyone wants their own project funding to be sufficient, which requires results to reflect. And getting the world's first jet plane to fly is Valksu's top priority, and it is only strange that he is not nervous.

"The engine is all normal."

"The instrument is all normal."

"The fuel supply system is normal."

"..."

As the staff checked the normal reports one after another, Valksu calmed down. At this time, he patted the shoulder of the test pilot next to him.

"Rolix, let's get started."

The Lolix test pilot with a parachute on his back nodded in response and said with a smile. "Don't worry, I will fly it back."

As the test pilots boarded the plane to start the engine, the F-101 jet began to taxi on the ground, faster and faster.

As the number on the meter turns bigger and bigger,

Test pilot Rolix violently pulled the joystick and then felt the plane lighter. The experienced he knew the plane had left the ground, and then increased horsepower to pull up the plane.

After seeing the plane flying up, the base was full of voices. Many people eating melons sighed.

"Look, this plane is really flying."

"Unexpectedly, it really flew."

As a tester, there was even more cheers.

"We succeeded."

Valksu also happily embraced his colleague Oan after seeing the plane lifted off the ground. "This time it succeeded."

The joy of success moved everyone. It's not easy. All these years of hard work and hard work day and night have been released at this moment. This peculiar plane flying in the sky also proved that their hard work and efforts were not in vain.

"Well, let's continue to test it, everyone cheers up."

Following Valksu's words, the testers present immediately recovered. Flying is only the first step in the Long March, and they will carry out various tests on it.

In the following test, the performance of the world's first jet aircraft was very surprising, and it far surpassed the piston aircraft in terms of speed and climb. However, the main reason for restricting its flying into the sky at present is the service life and high cost of the engine.

The actual situation of a 28-hour overhaul makes it not practical yet, and the cost is too expensive destined that this engine can only be used to verify jet flight.

But Valksu and Oan weren't worried at all, it was just like the world's first airplane. There is nothing to worry about if there is no practicality in a short time. As long as the investment in research and development is increased, the future will inevitably bear fruit.
