"Anderson ..."

Looking at home "a face of a sin"

Smiling boss, Anderson stopped him, a face of hope: "Don't talk, let me guess ... Are you ready to give us a salary?"

rise salary? How do you think so? Chen Genggong shook his head: "Of course not.

"No, that ... isn't it to give us holiday?"

Anderson asked again, although there is a little disappointed, if it is a few days, it is good.

Unfortunately, Anderson is destined to be disappointed, Chen Li shook his head again: "Anderson, what if you are holiday, will you tell you from you?"

When I heard Chen Geng, Anderson's expression was completely sighful, and he had sighed, and then looked up at his own boss, a person who lived: "BOSS, there is a living.

Anderson entering the drama mode is quite fun.

The surrounding engineers, watching Anderson's eyes are envy, they are very clear that the head can open this joke with the boss: What means that their two have a very good.

"There is a new research and development task to you,"

Chen Geng nod, at the same time, the engineers around him: "You all know the power triangle wing project before the company?"

How can I don't know how the power triangle items don't know, the installation and debugging work of the entire power system is that they are completed, just in "play"

Anderson in the model instantly played, immediately asked: "BOSS, are you deciding this project?"

Chen Geng nod: "Not only going to horses this project, and the engine also wants us to develop themselves.

R & D engine yourself? Although it is a bit surprised, I carefully think that all the engineers present are still surprised. Before this, the company didn't think about it directly from the Lai Kangming, the mainland, and Rotex these professional piston aerospace manufacturers to buy. Dynamic assembly, but on the one hand, these large piston aero engine manufacturers have no suitable power system.

On the other hand, they give the offer too long!

Taking Rotax's 914 series aircraft as an example, this is a four-stroke piston air engine with a horizontal opposite air-cooled + oil cooler mode, maximum power 106 hp, exhaust gas.

211 liters, you will be 78 kilograms, so this is a little bit slightly smaller than the CBX1000 engine of Fernandez company, slightly optimizes the clothes of the air power output curve, how much is the offer of Fernandes? 1.

50,000 US dollars!

It is only the assembly of the engine and the speed reducer, does not include a gearbox.

There is also an engine, which is also from Rotax, Rotax 275, which is a two-stroke air-cooled aerospace engine with maximum power 2.

94 horsepower, very suitable for single or double mode power triangle, then how much Rotax is the offer for this engine? $ 5,000!

This price can even buy a second-hand car that is very nice level and the car.

For ordinary people who don't understand the engine, the price of the aircraft is high, the air engine, the price is better, but for the engineers of the auto professional, this offer is simply robbery!

Yes, everyone knows that your engine is specifically optimized for high-altitude use, but for the power triangle wing, this is almost more than 1500 meters of flight height, at this altitude, even It is an ordinary motorcycle engine. The performance of the automotive engine will not be affected: Who has heard of the same car, there is abundant power in the coastal area, there is a significant loss of power in the sea level of the sea level? nonexistent.

Even in the era of the monocontrol, through the adjustment of the main amount of the monopolizer, the coupe along the coastal area is also useful in the Qinghai-Tibet Plateau.

Said that the piston aerospace engine is running over a long time in the high speed interval, so the strength of the engine is higher than that of the ordinary civilian cars, this is indeed, but the gap is not so big.

Or take the Rotax engine, the highest power speed of the Rotax 914 engine is 106 horsepower / 5800 revolutions, but this speed can only last for five minutes, can only be used in the takeoff and climbing stage, and the engine speed in the cruise phase is basically maintained. Regarding the 4000 to 4500 revolutions, for the engine of ordinary civil cars, of course, will not allow the engine speed to maintain the speed of this speed, but any civilian cars engine, allowing the speed to maintain at 3000 Does 4000 revolutions have a very serious impact on the engine? Certainly not!

Those who flew at the speed of one hundred and forty five, one hundred and forty-five.

6-liters of accumulated household cars, this time the speed has soared 3500 rpm / min, can you still use it well? After several years, the intensity of the Rotax series four-stroke aviation engine is really excellent than the red head 4G63, the red head F20A, the red head 2JZ-GTE, the red head RB26DETT is really excellent? This problem can actually give "huh, ..."

Two, nothing more than the piston aerospace engine is getting smaller, while the "Piston Air Engine" caused by the continuous propaganda of Polyponal aero-engine manufacturers such as mainland, LaComing, and Rotax is very high.

The B is already, those masters that have a strong hands-on ability use black birds, R1 and other promoters, F20A, 2JZ-GTE engine homemade aircraft is still less? Everyone is in the heart!

Now I heard the boss to say that I want to develop aviation engines, I have not completely exactly from "play".

The Anderson, which is out of the mode, is okay, and other engineers suddenly screamed: "Yes, we do engine!"

"Give the mainland, La Kangming" guys look at a little color!

"Let Rotax know our power ..."

Everyone is confident.

In the crowd, only Anderson cried a face: "Boss, our people ... I am afraid it is not enough."

"..."

The crowd suddenly sat quiet.

Including Chen Tong.

"The previous 0.

9L's grouped double-cylinder gasoline engine, the durability of the 350cc motorcycle engine, you have bought two sets of automatic gearbox from Mercedes-Benz ... "

: To say this, Anderson's face is looking at their own boss: "The boss, our people are really not enough.

Chen Geng is a bit embarrassed, it is true, this time, he has been adding tasks to Anderson here, but there is no increase in people, although engineers are most afraid of, but now, the R & D system is a bit can't hold. Only two ways to be in front of themselves: either hit the salary or recruit new people.

The rise in salary is impossible. The reason why Fairnad's R & D personnel can maintain such a strong energy, the most important reason is that they can get a certain proportion of dividends from the project, and the salary has risen again? "Wages are impossible to rise, no holidays,"

Chen Zi Hand Flutes, there is a project commission is not enough, but also pondering the salary? How much cheap will earn you: "But you can go to recruit people, look back, come back,"

See Anderson I want to talk, Chen Mongyi hooks: "It's so fixed!

The boss said so, what can Andon say? The only thing he can do is to look at their own boss.

Regardless of him, Chen Geng said: "There are three engines you have to develop, which are two strokes of 350cc wind oil cold-in-line engines, a four-stroke 700cc wind oil V4 engine and a four-stroke 1150cc wind oil cooling V6 engine, behind these two four-stroke V-type cylinder corner angle of 90 degrees.

I heard these data requirements, a group of engineers suddenly looked at each other: whether it is the angle of the cylinder, or the displacement of these engines, they all feel familiar, very familiar.

"Yes, you might think of it, the exhaust of these three engines is the multiple of the 175cc single-cylinder engine exhaust, the 350cc two-stroke internally double-cylinder gasoline engine can be seen as the three points of CBX1000 One, V4 and V6 can be seen as a one-third of our V12 engine, one-half, why do you want this setting, it is as possible for the three engine components as possible? Our existing parts are generally universal, reduce costs.

This 350cc two-stroke engine and the existing four-stroke engine have a big difference in structure, but I still ask for the generalization level of these two engine parts to reach more than 30%; V4 and V6 engine and our The vectors of the V12 engine have more than 80%.

In the performance indicator, I have the requirements of these three engines ... "

Chen Geng's request is that people are difficult, but the engineers still have no one to talk, but it is only silently to write down their own boss's requirements for these engines. Although these requirements are very difficult, but this is not the boss. Do you have to work for him? Anderson raised his hand: "Boss, mainland, Lecming, Rotax engine is horizontally opposed to add cold, oil-cooling design, which also proves that this structure is more suitable for aviation purposes, why don't you use horizontal opposition but Use a 90 degree V-type structure? "

The cooperation is too good, Chen Wanto is a good look at Anderson in his heart, and said: "Because I don't like the power output curve of the engine of the engine, I prefer 90 compared to the horizontal opposition." V-type cylinder layout in degrees angle.

The power output characteristic of the horizontal opposing engine is "convex"

The shape, the beginning is weak, very gentle, etc. After the speed has come to a certain point, suddenly rises sharply, and it will show a high power output characteristics after a short speed change, but when the speed is high, the power output It suddenly begins to decline, like neuropathy, the characteristics, curve, and operation of the entire power output ... far from the V-type cylinder structure of the 90 degree angle, the only advantage is low.

Listening to this boss, I nodded at all.
