While the whole world was talking about Edel's ascension to the Bulgarian throne, in a heavily guarded air force base on the outskirts of Lviv, a group of people in blue overalls were busy in front of a strange-looking aircraft.
This aircraft is weird because it does not even have the most basic propeller. There is no propeller installed on the entire aircraft.
Such a weird-looking aircraft also attracted many people from the air force base to watch.
"Dolev, do you think this thing can fly?"
Among the onlookers, a base personnel wearing a flight jacket asked about his colleagues.
The stopped Dolev shrugged and replied with a don't ask me expression. "Who knows. But I heard that this is the latest achievement of the Lviv branch of the Power Research Institute, and it may be able to fly." Get up."
After finishing speaking, Dolefu continued, "But if you ask me to fly, I won't dare."
Yes, Dolev was not at all worried about this weird-looking aircraft. Even though he was known for his boldness in the Fourth Air Wing, he still refused to try such an aircraft without propellers.
There are many people like him in the base, and the focus of everyone's discussion is whether this thing can fly. And such discussions will inevitably reach the ears of the staff who are busy in front of this weird aircraft. Faced with these discussions As the leader of the project, Valxu was not surprised at all.
Valcsu is the head of the jet engine project at the Power R&D Center. He graduated from the Power Engineering Department of the University of Bucharest and was recruited by the National Power Laboratory with his excellent results. After working in the Power Laboratory for several years, Valcsu developed a keen interest in jet engines.
In fact, jet aviation power developed very early. Since the 17th century, some people have tried to use steam power or internal combustion engines to realize usable jet engines, such as the Dutch physicist Huygens.
Henri 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 gas propulsion in the space behind it. This was called a thermal jet engine. This was Although this kind of engine has a simple structure, it is heavy, lacks thrust, and has poor practicality.
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 in 1915 that used gas and compressed air to increase the range of artillery shells. This device compressed and ignited the airflow when the artillery shells flew at high speed through a variable-section air inlet, thus Provide thrust.
However, the Austro-Hungarian army did not adopt its design in the end, so he registered the patent for the supersonic ramjet engine in Germany in 1928 and obtained it in 1932. The ramjet engine was thus born.
In 1921, Frenchman Maxime Guillaume patented the first jet engine. His design was similar to an axial flow jet engine.
In 1928, Frank Whittle of the Royal Air Force College in Cromwell, England, proposed a new jet engine design. In January 1930, Whittle submitted a design patent for the jet engine and received the patent in 1932. Whittle Whittle's design was to install a two-stage axial flow compressor in front of a large centrifugal compressor and be driven by a turbine. Later Whittle removed the front axial flow compressor and used a larger centrifugal compressor.
Since jet engines continue to develop abroad, as the main power research unit in Romania, the National Power Laboratory cannot turn a blind eye to it. With the support of the old dean Rudolf Diesel, the National Power Laboratory is also developing
jet engine.
It should be noted here that Rudolf Diesel no longer continues to develop diesel engines. He is over 70 years old and has already become famous with the widespread use of diesel engines. Currently, his main disciples continue to develop this diesel engine.
The development of jet engines was left in the hands of Valcsu, who was the most knowledgeable about jet engines in the power laboratory. Valcsu lived up to expectations, and finally succeeded in cooperating with his German colleague Hans von Oan.
(the result of Rhodes cooperation), the new jet engine was successfully developed.
During the ground test, this axial flow jet engine produced a thrust of 5,000 N, which surprised researchers from both countries. This means that this jet engine has reached the standard for use. Since it has reached the practical standard, it will not fly
It was simply too uncomfortable at once.
Therefore, under Valcosu's promotion, a new aircraft was born specifically for flight testing of this engine. This new aircraft, labeled F-101, has a total length of 9.4 meters and uses a lower wing. Because of the engine
On the abdomen, it looks a bit like an inflated pufferfish, without the slenderness of other propeller aircraft at all.
This is also the reason why most people in the base don’t like it. Appearance is really important to an aircraft.
But this is not so important to Valxu and Hans von Oan today. First they have to make this aircraft fly.
"How's the inspection going?"
Valxu, with some sweaty palms, asked his staff. This is the final inspection before the flight. If the plane can't fly, he can't do it. You must know that the power laboratory not only develops jet engines, but also traditional
The piston engine power laboratory is developing several models, such as a 900-horsepower radial air-cooled engine, a 1,200-horsepower straight-cylinder liquid-cooled engine, and a 1,350-horsepower V-shaped liquid-cooled engine. It can be said that it is the only aircraft engine in the world.
There are many kinds.
There are even many projects that not only focus on the work at hand, but also take the opportunity to prepare for the next step of pre-research in advance. For example, he knew that the 900-horsepower radial air-cooled engine project headed by Krishid was preparing for the next 1,200
Ma Li did preliminary research.
Not to mention the current flagship products of the Power Laboratory, gasoline engines and diesel engines. These two engines respectively rely on the prosperous automobile industry and Rudolf Diesel's outstanding capabilities, allowing the Power Laboratory to obtain sufficient funds. Although the funds are sufficient, but
Competition is indispensable. Everyone wants to have enough funds for their projects, which needs to be reflected in results. Getting the world's first jet aircraft to fly is Valxu's top priority. It's no wonder he's not nervous.
.
"The engine is fine."
"Every instrument is fine."
"The fuel supply system is normal."
"..."
As the staff checked the normal reports one after another, Valxu calmed down. At this time, he patted the test pilot beside him on the shoulder.
"Rolix, let's begin."
The Rolix test pilot, who was carrying a parachute, nodded in response and said with a smile, "Don't worry, I will fly it back."
As the test pilot boarded the aircraft and started the engine, the F-101 jet began to taxi on the ground, getting faster and faster.
As the numbers on the meter rotate larger and larger,
Test pilot Rolix pulled the control stick sharply and immediately felt the plane lighten up. The experienced man knew that the plane had left the ground, and then he increased the power to pull up the plane.
After seeing the plane take off, the base became even more crowded. Many people sighed.
"Look, this plane is really flying."
"I didn't expect it to really fly."
As a tester, there was even more cheers.
"We succeeded."
Valxu also happily hugged his colleague O'an after seeing the plane take off. "It was a success this time."
The joy of success moved everyone. It was not easy. So many years of hard work and hard work day and night were released at this moment. This strange aircraft soaring in the sky also proved their hard work and hard work.
Following Valxu's words, the testers present immediately came to their senses. Flying was just the first step in a long journey of thousands of miles. Next, they would conduct various tests on it.
In the following tests, the performance of the world's first jet aircraft was very surprising. In terms of speed and climb, it far surpassed the piston aircraft. However, the main reason that currently restricts it from flying in the sky is the use of engines.
lifespan and high cost.
The actual situation of overhauling every 28 hours makes it impractical, and the cost is too expensive, which means that this engine can only be used to verify jet flight.
However, Valcsu and Oan are not worried about this at all. This is just like the world's first aircraft. There is nothing to worry about if it is not practical in the short term. As long as the investment in research and development is increased, it will definitely bear fruit in the future.
