I don't blame Zhuang Jianye for this, I blame only the training aircraft equipped by the Thai Air Force for being too strange.

The training aircraft produced by the German company Rheinland Aircraft Manufacturing Co., as its name suggests, has a large fan, which does not mean that the training aircraft uses a more advanced turbofan engine.

On the contrary, such a fixed-wing trainer uses an Acheson 250-C30 turboshaft engine produced by Rolls-Royce, which is the same as the Bell 206 helicopter in the United States.

This alone is enough to subvert people's imagination, even after a few decades, no one dares to open such a big brain.

However, in Europe in the sixties and seventies, in order to prevent the invasion of the Soviet Union, combat aircraft were equipped with the so-called ultra-short take-off and landing capability, and some aviation powers such as Britain, France, Germany, and Italy have been constantly exploring this road.

The British Harrier VTOL fighter and the French F-1 fighter were all products of this time.

Although Germany was limited in fighter jets due to its defeat in World War II, it still tried in this regard, and the "Fan Coach" was one of the results.

The turboshaft engine is used to push a large fan at the rear of the fuselage, giving it a strong reaction force to complete the power delivery.

It is precisely because the power choice is too alternative, coupled with the need for short take-off and landing, that the layout of the "fan coach" is also non-mainstream, for example, in order to stabilize the center, the forward-swept wing structure is adopted, and the rear part adopts a T-shaped vertical tail, which looks very incompatible with the traditional layout of the aircraft in the impression.

But it is such an alternative and strange aircraft, but the flight performance is very good, especially the rear engine and the stability of the forward-swept wing structure at medium and low speeds, so that the "fan trainer" can simulate many effects of jet fighters.

In addition, the small turboshaft engine has good economy and low cost, which is a very good high-quality training aircraft integrating primary and middle school.

Otherwise, it would not have been possible for the Thai Air Force to purchase 47 aircraft in one go for the training and teaching of F-5 fighters and the adaptive training of pilots for the return to flight.

The main reason is that the entry into service of the "Fan Trainer" has broken the original primary, intermediate and then advanced three-level training aircraft training system, and the use of "Fan Coach" can complete all the training subjects of the primary and intermediate levels, plus the Thai Air Force has not yet been equipped with third-generation fighters, and there is a lack of training subjects for advanced training aircraft.

Therefore, after completing the training subject of "Fan Instructor", you can directly fly the F-5 fighter to take off and perform the mission.

Reducing the use, maintenance, and maintenance of the first-class aircraft and the maintenance of the personnel team is equivalent to saving a lot of expenses.

If it weren't for this, the Thai Air Force would not continue to retain the fleet size of the "Fan Coach", and would have been swept into the garbage heap long ago.

However, it is such a model with good performance, and even faintly capable of subverting the existing mainstream training aircraft training system, but it has suffered a serious setback in its own country, not that the Germans themselves look down on it, but just like the actor company in Germany, no matter how good the product is, because of the original sin of World War II, several forces will still put pressure on it.

Especially in the United States, the three-level training aircraft system is running well, and the major aviation giants are counting on the primary, medium, and high three models to desperately make a little money, and the Germans suddenly jumped out and said that the big guys should not be so troublesome, and my "fan coach" can do all the work of the junior coach and the intermediate training aircraft.

What will the Americans think when they hear this? Of course, they just stretched out their fingers and pressed them to death without saying a word.

As a result, the sales performance of the "fan coach" in Germany can no longer be described as miserable, only equipped with less than ten aircraft, which can be regarded as the spiritual encouragement and encouragement of the German Rhine aircraft manufacturing company, only the Thais think this aircraft is good, and they asked for 47 in one breath, becoming the world's largest user.

And then...... There is no then.

Because this amount did not recover even the minimum R&D expenses, it was obviously a blood loss, so the German aircraft manufacturing company Rheinland went bankrupt within a few years, but the Germans were also conscientious, and the other company that took over continued to fulfill the contract with Thailand, providing spare parts and maintenance work.

It's a pity that the German company still didn't hold on, and it also declared bankruptcy more than a year ago, and this time it broke more completely, selling everything that could be sold, including the spare parts production line of the "fan coach".

Fortunately, the Thai Air Force has a lot of inventory, and in the past year, it has barely survived, but with the gradual reduction of accessories, the state of the aircraft has gradually declined, which has no choice but to find other ways.

For example, the rest of Europe, or the United States, the big backer behind it.

As a result, these European and American countries showed extremely unusual enthusiasm for Thailand, as if the macho man had seen the goddess he was looking for, what kind of old plane to repair, let's drive it directly in one step...... How good is it to buy a new plane?

As a result, the British "Eagle" training plane, the French "Alpha Jet" training plane, and the American T-38 training plane were like all kinds of macho men scratching their heads in front of the little princess of Thailand, shouting shamelessly, "Choose me, choose me......

The problem is that the Thais just want to build a plane, but they don't want to sell it, why is it so difficult?

European and American aviation giants frowned, and immediately calculated the account for the little princess in Thailand, Germany's "fan coach" has been out of production for many years, and if you want to do in-depth maintenance, you have to restart the parts production line, which is not a small number, and then you have to train workers, which is an astronomical amount, and then it is to re-measure, design tooling, make plans, etc., all down, the cost of deep maintenance of a "fan coach" is more expensive than buying a new aircraft of the same type.

All in all, in short, if Thailand wants in-depth maintenance, it can first take the initial investment of more than one billion US dollars, and they guarantee that all kinds of trends can be tossed casually.

Thailand knows that this is a pit dug by European and American aviation giants, but there is nothing to be done, this is the sadness of the lack of support from the aviation industry, what people really say, you don't even have a chance to refute, except for choosing to be taken away by the wolf, nothing else can be done.

Originally, the Thai Air Force had accepted its fate, but it was not expected that its own Royal Aerospace Industries would rise all of a sudden, and the flame of hope, which was about to die, immediately burned, and then rushed to the Tengfei Group...... A partner who only thinks about the user.

Zhuang Jianye looked at the strange-looking "fan coach" and the technicians who were busy working around the plane, and his thinking began to diverge involuntarily, until he found that Lin Guanghua, who had a little oil on his body, came over, and then glanced around, and found that there were no outsiders beside him, so he asked in the southwestern dialect of China: "How is it?"

Lin Guanghua didn't have any surprises, and also replied in the southwestern dialect: "It should be fine, but ...... We may be a little short of the engine after all, after all, our turboshaft engine has not been used yet, I don't know if it will work. ”
