"Anderson ......"

Looking at his boss with a "sinister" smile, Anderson hurriedly stopped him and said with a look of hope: "Don't talk, let me guess...... Are you going to give us a raise?"

How can you think about how beautiful? Chen Geng shook his head decisively: "Of course not. ”

"No, that'...... Are you going to give us a holiday?" Anderson asked again, and while it was a bit disappointing not to raise wages, it would be nice if you could take a few days off.

It's a pity that Anderson is destined to be disappointed, Chen Geng shook his head again: "Anderson, do you think that if it is a holiday, I will come to inform you in person?"

Hearing Chen Geng's words, Anderson's expression completely collapsed, he sighed heavily, and then looked up at his boss with a sad face, with an appointed look: "Boss, if you have any work, just say it." ”

Anderson, who entered the drama mode, was quite fun.

The surrounding engineers, looking at Anderson, were full of envy, and they knew very well what it meant for the boss to be able to make such a joke with the boss: it meant that the two of them had a very good relationship.

"There's a new R&D task for you," Chen Geng nodded, and at the same time beckoned to the surrounding engineers: "You all know the power delta wing project that the company did before, right?"

How could they not know that the installation and commissioning of the entire power system was completed by them, and Anderson, who was still in the "drama spirit" mode just now, instantly appeared in the play, and immediately asked excitedly: "Boss, have you decided to launch this project?"

Chen Geng nodded: "Not only do we have to start this project, but we also have to develop the engine ourselves." ”

Develop your own engine?

Although a little surprised, but think about it carefully, the engineers present were not surprised at all: before this, the company did not think of buying powertrains directly from professional piston aero engine manufacturers such as Lycomingming, Continental, and Rotex, but on the one hand, these major piston aero engine manufacturers did not have suitable power systems. On the other hand, the offer they give is outrageous!

Take Rotax's 914 series aero engine as an example, this is a horizontally opposed air-cooled + oil cooler mode four-stroke piston aero engine, with a maximum power of 106 horsepower, an exhaust volume of 1.211 liters, and a weight of 78 kilograms, just such a thing that is slightly lighter than Fernandez's own CBX1000 engine and slightly optimizes the air power output curve, what is the price for Fernandez?

$15,000!

Just the assembly of the engine and reducer, excluding the gearbox.

There is also an engine, also from Rotax, the Rotax 275, which is a two-stroke air-cooled aero engine with a maximum power of 2.94 hp, which is very suitable for a single or double power delta wing, so what is Rotax's offer for this engine?

$5000!

At this price, you can even buy a used car with a very good grade and condition.

For ordinary people who don't understand engines and are used to the high price of flying machines, it is understandable that the price of aero engines is a little higher, but for a room full of automotive professional engineers, this offer is simply a robbery!

Yes, we all know that your engine is specially optimized for high-altitude use, but for the power delta wing, the flight altitude of this thing will hardly exceed 1500 meters, and at this altitude, even the performance of ordinary motorcycle engines and automobile engines will not be affected: who has heard that the same car is full of power in coastal areas, and there is a significant loss of power in the relatively high altitude of Sichuan and Chongqing?

Inexistent.

Even in the carburetor era, through the adjustment of the carburetor main measuring hole, the cars in the coastal areas were just as easy to use in the Qinghai-Tibet Plateau.

It is said that the piston aero engine runs in the high speed range for a long time, so the strength requirements of the engine are higher than that of ordinary civilian car engines, which does exist, but the gap is not so big.

Taking the Rotax engine as an example, the Rotax 914 engine has a maximum power speed of 106 hp/ 5800 rpm , but this speed can only last five minutes, can only be used for take-off and climb phases, the engine speed in the cruising phase is basically maintained at about 4000 to 4500 rpm, for the engine of ordinary civilian cars, of course, it will not keep the engine speed in this speed range for a long time, but the engine of any civilian car, let the speed be maintained at 3000 to 4000 rpm for a long time, will it have a very serious impact on the engine?

Definitely not!

Those 1.6-liter family cars that are running at a speed of 134 or 145 at every turn on the highway have soared to 3500 rpm at this time, but they are not the same as the good ground?

After a few years, is the strength of the rotax series of four-stroke aero engines really better than that of the Red Head 4G63, Red Head F20A, Red Head 2JZ-GTE, and Red Head RB26DETT?

This problem, in fact, can be given "hehe......" two sounds, it is nothing more than that the market for piston aero engines is getting smaller and smaller, and the continuous propaganda of piston aero engine manufacturers such as Continental, Lycomingming, rotax and other piston aero engine manufacturers caused by the "piston aero engine price is very high" B grid, those masters with strong hands-on ability to upgrade motorcycle engines, F20A, 2JZ-GTE engines and other self-made aircraft are less?

Everyone is holding their breath in their hearts!

Now that I heard the boss say that he wanted to develop an aero engine, Anderson, who had not completely broken away from the "drama spirit" mode, was okay, and the other engineers suddenly shouted:

"That's right, we make our own engines!"

"Give the continent and Lycoming these guys a little color!"

"Let Rotax know our ......"

Everyone is confident.

In the surging emotions, only Anderson cried with a sad face: "Boss, our manpower ...... I'm afraid it's not enough. ”

“......”

The crowd fell silent.

Including Chen Geng.

"The previous 0.9L Zhili twin-cylinder gasoline engine, the durability treatment of the 350cc motorcycle engine, and you bought two sets of automatic transmission ...... from Mercedes-Benz a few days ago": Speaking of this, Anderson looked at his boss with a resentful face: "Boss, we really don't have enough manpower. ”

Chen Geng is a little embarrassed, indeed, during this time, he has been adding tasks to Anderson's side, but the manpower has not increased much, although the engineer is most afraid of not having a job, but now, the R&D system is a little unbearable, and there are only two ways in front of him: either raise the salary, or recruit new people.

It is impossible to raise wages, and the most important reason why Fernandez's R&D personnel can maintain such vigorous energy is that they can get a certain percentage of dividends from the project.

"It's impossible for wages to rise, and there are no holidays," Chen Geng waved his hand, it was not enough to have a project commission, and he was still thinking about raising his salary? How could there be so many cheap for you to earn: "But you can go and recruit people, and go back and type a report," Seeing that Anderson still wanted to speak, Chen Gengyi waved his hand: "That's it!"

The boss said so, what else could Anderson say? The only thing he could do was look at his boss with resentment.

Regardless of him, Chen Geng continued: "There are three engines you want to develop, namely a two-stroke 350cc air-oil-cooled in-line twin-cylinder engine, a four-stroke 700cc air-oil-cooled V4 engine and a four-stroke 1150CC air-oil-cooled V6 engine, and the cylinder angles of the latter two four-stroke V-engines are 90 degrees. ”

Hearing these data requirements, a group of engineers suddenly subconsciously looked at each other: whether it was the angle of the cylinder or the displacement of these engines, they all felt very familiar, very familiar.

"That's right, you may have thought that the displacement of these three engines is a multiple of the displacement of our 175cc single-cylinder engine, the 350cc two-stroke inline twin gasoline engine can be regarded as one-third of the CBX1000, and V4 and V6 can be regarded as one-third or one-half of our V12 engine.

The structure of this 350cc two-stroke engine is very different from the four-stroke engine we already have, but I still require the two engine parts to be more than 30% common, and the V4 and V6 engines and our V12 engine have more than 80% common parts.

In terms of performance indicators, my requirements for these three engines are ......"

Chen Geng's requirements sounded embarrassing, but the engineers still didn't speak, just silently wrote down their boss's requirements for these engines, although these requirements sounded difficult, but isn't this the reason why the boss invited himself to work for him?

Anderson raised his hand: "Boss, the engines of Continental, Lycoming, and Rotax are all horizontally opposed with air-cooled and oil-cooled design, which also proves that this structural method is more suitable for aviation use, why don't you use horizontal opposition instead of a 90-degree V-shaped structure?"

The cooperation is so good, Chen Geng silently praised Anderson in his heart, and said: "Because I don't like the power output curve of the engine with horizontally opposed cylinders, I prefer the V-shaped cylinder layout with a 90-degree angle compared to horizontally opposed." ”

The power output characteristics of the horizontally opposed engine are "convex" shaped, no force at the beginning, very gentle, and then the speed suddenly rises sharply after a certain point, and after a short speed change, it shows a high power output characteristic, but when the speed of the high road after a certain point of power output suddenly began to decline, the same as neuropathy, the characteristics of the whole power output, the curve, the smoothness of the operation...... It is far worse than the engine with a 90-degree V-cylinder structure, and the only advantage is that the center of gravity is low.

Hearing their boss say this, everyone nodded subconsciously.
