After hearing Brad's answer, Goldstein was stunned for a moment, and then showed a knowing smile.

Obviously, these guys who are engaged in academics are no different from them in business.

A paper with a high impact factor may also mislead potential opponents in the direction of research and development.

Win hemp.

Win-win, i.e. I have to win twice.

"Can it be any faster?"

Now that Brad has determined the right research direction, Goldstein, as the representative of the company and Party A, is naturally more concerned about when the results will be produced.

Although the NGAD project has not yet been skimmed, and the supporting fifth-generation aero engine has not even specified specific technical parameter requirements, the relevant technology can be applied to the next-generation civil aero engine that General Electric is promoting.

Better cooling means higher pre-turbine temperatures, and in addition to intuitively increasing thrust, higher pre-turbine temperatures can also reduce fuel consumption while keeping thrust constant – because at the same power, the compressor needs less power to do and consumes less fuel.

For airliners, this is lore.

You know, Airbus is pushing ahead with their A3XX megaliner program against the Boeing 747, and General Electric is currently ambitious and ready to compete with Rolls-Royce in engine selection.

It is expected that at least about 300 of these superliners will be produced, and considering that the engines need to be replaced several times during the whole life, it is a huge market of 3,000-4,000 units.

You must know that this is not a gadget like CFM56, the A3XX needs at least a large bypass ratio turbofan with a thrust of 35-40 tons, and each one is surprisingly profitable.

What's more, after losing to Pratt & Whitney in the selection of two fourth-generation military engines, although the F119 and F135 actually have a lot of parts produced by General Electric, and there is no loss in revenue, the company's stock price has been running at a low level.

This is definitely not good news for the management team.

Of course, GE has a big business and will not rush to change people in a short period of time.

But at least for the next few years, the company will need a landmark victory to boost market confidence.

And a project like the A3XX is obviously a great opportunity.

"What ...... this?"

Brad hesitated:

"In my experience, research is about maintaining a steady pace of work, and if you blindly increase the workload to advance the R&D schedule, it is likely to be counterproductive in the end."

Just as Goldstein nodded, ready to let the topic go, the other party suddenly added.

"So...... Gotta add money! ”

"I need to recruit some more interns, more experimental samples, and supercomputing resources!"

"Get ......"

Good guys, it turned out to be asking for money.

However, for such an important and promising project, GE, which has deep pockets, is indeed not short of millions of dollars.

Seeing such an energetic and confident Brad, Goldstein also had a sense of openness in the future, and immediately assured the former:

"Okay, I'll apply to the top when I get back, and GE will do its best to support your research!"

"Thank you, it's an honor to work with such a great (have) big (money) company as General Electric!"

……

Although the heating speed of electric heating is not as good as the traditional method of direct fuel injection ignition, the temperature control accuracy is far more than the latter, and the probability of obtaining effective experimental data has soared from less than 20% in the past to nearly 100%.

Not to mention the advanced all-digital monitoring and recording equipment, which can simplify the experimental operation to no more than five steps, greatly liberating manpower and reducing many problems caused by human error.

So, before Braid and Goldstein finished their second cup of coffee, Regina, a female graduate student assigned by the former to conduct the experiment, knocked on the door and walked in.

He also has a floppy disk in his hand.

"Professor, the part of the data you asked for has already come out, and it's all in it."

Brad put down his half-drunk coffee, took the floppy disk, and inserted it into the floppy drive.

Within a few minutes, a black-and-white map of the temperature distribution was displayed on the computer screen.

Regina didn't just leave the office, but introduced to the screen:

"The hot spots on the leading edge of the high-pressure turbine guide vanes will gradually migrate outward with the increase of thrust, and the migration path is slightly different from our previous predictions, but the overall law is the same, although the hot spots still exist in the control group with impact cooling, the temperature has been reduced a lot compared with the control group."

Professor Brad's research group is not small, and the competitive pressure is even greater, so she must seize such an opportunity to perform.

"The problem now is that after applying jet cooling, the top part of the turbine blade will accumulate more heat than in the past, and it is difficult to arrange the jet seam in this position, and the effect of air film cooling alone is average, and the temperature does not exceed the maximum limit."

"It's not a big deal, the top area has always been the most difficult area on turbine blades, and the change in the position of the hot spot would have required further testing, and the first test to achieve such obvious results is already very good, at least it proves that our idea of using impact cooling to focus on strengthening is correct!"

Looking at the picture in front of him, Brad was clearly in a good mood.

Is it a big problem that the numerical analysis results are inaccurate?

It's meant to provide a reference.

There is no real person who can calculate that it is basically close to the actual situation, right?

No way?

The corners of Brad's mouth pulled out a joyful arc.

This means that his research group has come to the forefront of the world not only in compressor design, but also in turbine design.

It even surpassed the University of Oxford, which provided this MT1 test platform.

"After processing the experimental data and equipment, we will organize a small banquet in the evening, which can be regarded as welcoming Mr. Goldstein!"

……

It should be said that Blade's ability is still relatively large.

He can consider the complex non-uniform factors at the turbine inlet without relying on the test, and use impact cooling to deal with it in a targeted manner, which is definitely a hero in the field of aviation development.

The only fly in the ointment is that his calculations were done before he got to the MT1 platform, so the subject of research has always been a single turbine blade.

Of course, this is not Brad's problem.

At the level of supercomputing at the end of the 90s, relying on normal calculation methods, it is really impossible to model the aerothermal coupling of the hot end part of the entire aero engine.

But if he heard Chang Haonan's evaluation of the "leftovers" article, he would realize that there is a limit to impact cooling.

Adding cooling groove joints to all hot areas, which is a headache for the head and feet, will have a very poor effect when it comes to the vicinity of the section wall.

Therefore, the accumulation of heat in the top part of the turbine blades is not a trivial matter.

Especially in a real aero engine.

Since both the combustion chamber and the turbine structure are surrounded by the casing, the overall heat dissipation conditions are actually worse than those on the test bench.

The high-temperature air flow sent by the combustion of jet fuel in the combustion chamber is not as stable as that of electric heating......
