Hawk trainer is a medium / advanced jet trainer designed by NiuGuo hawk Sidley company for NiuGuo air force, which can perform short-range air support missions. The aircraft is used to replace the first generation jet trainer such as "jet headmaster", "mosquito" and "Hunter".

Due to the merger of hawk Sidley company and NiuGuo aircraft company, it is called NiuGuo aerospace company (BAE). So now it is also a fist product of Hangyu company.

NiuGuo has always attached importance to the role of training aircraft. In the late 1960s, NiuGuo air force put forward the request to replace most of the active aircraft of NiuGuo air force training command in the 1970s; In addition, as several new aircraft are planned to enter the first line of service, it is necessary to modify the whole flight training system and develop a new generation of medium / advanced jet trainer to ensure economic and effective training and meet the requirements of future air combat.

They are interested in economy. If they train directly with fighters, the cost is too high.

After bidding, hawk Sidley won the bid and Rolls Royce's non afterburner turbofan engine "Adur" was used as the power unit. Eagle entered the development stage of five pre production aircraft without prototype development,. Batch production aircraft entered the army on November 4, 1976.

So far, this aircraft is less than five years old.

Although it has begun to export, it has not been exported to several countries after all, and it is not accessible to the Han air force. Don't you know everything and can do everything? Now, what are the shortcomings of our plane? If you can't say it, let me see how I tease you.

Kelly's big blue eyes looked at Chen Rui, full of provocation.

It is no wonder that in the western world, there are always a group of people who despise the ancient oriental countries. After all, since the Opium War, the Han country has always been a weak chicken image, which is the object of arbitrary slaughter by these countries.

Therefore, we must severely suppress the other party and let the other party know the power of the Han air force.

"The advantage of this trainer is its small size, flexibility and good mobility." Chen Rui began his analysis: "it can complete a lot of flight training projects. At the same time, it has a good vision of the front and rear seats. It is a good trainer."

Chen Rui said a good word. All the faces on the scene showed a proud look. Indeed, this is a very good trainer. Otherwise, how could it be selected by your side as your own flight performance aircraft?

"However, if its shortcomings are obvious, it adopts a relatively simple mechanical hydraulic control, and we know that the new three generations of aircraft have begun to adopt telex operation. There are many different characteristics between hydraulic operation and telex operation, so the pilot has to adapt again."

Chen Rui said so. The people present had no objection.

New fighters have become popular with telex control. Now NiuGuo's latest is the gale fighter, which uses telex control, and its operating characteristics are indeed different.

Chen Rui has the confidence to say so. His j-14 and J-7 are controlled by telex.

"This is not a defect. I want you to say what are the disadvantages of our plane," Kelly continued to Chen Rui.

"The disadvantages of this aircraft are poor longitudinal handling stability; insufficient engine thrust; poor directional / lateral stability; sudden and unpredictable stall; sudden nose up when the speed brake is deployed."

When Chen Rui said this, everyone present changed color, and Kelly suddenly lost her voice and said, "how do you know?"

These are all shortcomings, and these shortcomings can only be known by those who fly over it. Who would have thought that Chen Rui actually knows the shortcomings of this aircraft?

Of course, Chen Rui knows that he simulated this aircraft when he was in the flight simulator. He also fantasized that if he had the same trainer, he could greatly reduce the training cost.

However, now that he said so, everyone present was surprised. How did he know?

"This aircraft is powered by Adur 151-01 non afterburner turbofan engine, with a thrust of 23.13 kn, that is, 2360 kg. The empty weight of this aircraft has reached 3750 kg, and the maximum takeoff weight has reached 8500 kg. In this case, how can the engine thrust be sufficient?"

Of course, Chen Rui can't say that he has flown a variety of simulators. He can only use the existing data to analyze, and he is right.

The engine thrust is seriously insufficient, which is a basic factor restricting the performance of this aircraft. The thrust weight ratio is quite low, which may be more fuel-efficient. However, during the flight performance, the performance of this aircraft is seriously limited. For example, to make a climb, you must have speed, and vertical climb is even more impossible. How can it be compared with your own fighter?

During the flight performance, the thrust weight ratio of the j-14 fighter was more than 1, and all kinds of movements were flowing, which was much better than their trainer.

"At the same time, because it is a trainer, the front and rear cockpits are arranged high and low, which greatly increases the air resistance and longitudinal instability. However, the rudder surface of the elevator at the tail is not large enough, so these problems just mentioned will appear."

"The most wonderful thing about the design is the speed reducer. Ordinary speed reducers are all on the back of the aircraft, but this aircraft is actually set between the abdominal fins. This single-chip speed reducer has lower weight and cost than the speed reducers usually installed on both sides of the fuselage, but it can not be used during landing. Moreover, when it is used, it will produce additional torque, causing the nose to land inexplicably Yang, it's a killer of pilots. "

Chen Rui said this with ridicule. He had a good impression on the people present. After all, he was a colleague and everyone was the pride of heaven. However, since this Kelly despised herself, she could only say what to say and tell all these things.

A design error is a design error.

When Chen Rui finished, he calmed down at the dinner table. No one made a sound. Everyone was shocked. Chen Rui's analysis was good!

This guy is really a ghost. How else would he know?

"As a trainer, these shortcomings are harmless, but as a performance machine, some actions such as vertical climbing are not very wonderful. It is suitable for formation performance and not for stand-alone performance." Chen Rui continued to analyze.

The red arrow flight performance team relies on multi aircraft formation, especially the 9-aircraft formation, which dazzles the audience and achieves a shocking effect through various complex formation performances. However, if it is a single machine, it will be nothing to see.
