Chapter 505

Master Ju's words are true. The starting point for Tengfei airlines to light up the turbine power unit is to imitate Hamilton's t-62 APU auxiliary power unit.

After some polishing and improvement, it has developed into D-20 series gas turbine power plant.

Although this series does not have the D-30 series, which is used for the combined cooling and power generation equipment, and the d-40 series, which is used for the aircraft engine, is as eye-catching and shining as the d-50 gas turbine installed on the ship.

However, it is the most widely used and mature gas turbine power plant of Tengfei airlines.

The reason for this is very simple. Although the D-20 series gas turbine power unit has not been adopted by the aircraft platform and has become a genuine APU auxiliary power unit, it has been widely used in the UAV system by Tengfei airlines and has become an indispensable ground power generation equipment, namely the so-called GPU (ground power unit).

With the continuous expansion of sales volume in the field of UAV in recent years, besides several UAVs in each system, a GPU shelter car equipped with D-20 series gas turbine power unit is inevitable. In addition, a set of D-20 series gas turbine power unit is used as replacement spare parts. In a few years, the shipment volume of D-20 series gas turbine power unit is increasing Second only to UAV, it has become the second best-selling aviation product of Tengfei airlines.

However, due to the need to match the UAV system for sales, the external product name is generally replaced by the UAV system, so it is not very eye-catching. However, such a humble D-20 series gas turbine power plant has propped up half of the whole Tengfei aviation power plant, becoming the biggest source of revenue for the Golden beast like Tengfei aviation power plant.

Since the day when it was put into production, the production line has not been cut off. If not, how could it be that Zhuang Jianye called last night and sent it today? The reason is very simple. The D-20 series gas turbine power plant is still in full swing. What specifications and power do you want? Just adjust the interface and pipeline a little, you can directly load the general aviation aircraft from the production line, It's thousands of miles away.

At this speed, not to mention the head of the navy who followed Zhuang Jianye was surprised, even the employees of macdow company, such as FOSS, were also surprised.

At yesterday's communication meeting, Zhuang Jianye and others patted their chests and promised that the APU for replacement would be delivered before 4 p.m. this afternoon. Although FOSS looked anxious on the surface and couldn't wait for the maintenance performance, it's really hard to hear what Zhuang Jianye said.

After all, fosse's focus is to win the favor of CAAC's decision-makers. In other words, the cooperation with Tengfei Airlines is just to show McDonnell Douglas's attitude, so that CAAC's decision-makers can see the determination of McDonnell Douglas's technology for the market, so as to sell more MD-11 wide bodied mainline airliners.

Therefore, FOSS doesn't care whether Tengfei airlines can repair it, when it will be repaired or what it will be like. It's just a bait. As long as the fish can be fished, which fisherman cares whether the bait is alive or dead?

What's more, despite his commercial interests, FOSS felt that what McDonnell Douglas engineer, who was in conflict with him last night, said was very reasonable. With China's aviation technology, it is estimated that he has never seen how to use the technology on the DC-10, let alone how to repair it.

Because of this, when Zhuang Jianye said that the APU would be in place before 4 p.m. this afternoon, FOSS and others just listen to him. It's better to get there, but it doesn't matter if they don't get there. Anyway, it's not bad to want to catch big fish. These two days, we have to be a little patient.

As a result, I didn't expect that the APU of Tengfei Airlines arrived at the Navy's military airport by a small cargo plane before four o'clock, which really surprised FOSS and others.

"True or false?"

The slight surprise passed quickly, and a technical personnel with a beard and a toad mirror frowned and asked.

Another fat technician standing next to him shook his head: "I don't know, but I'm sure there's definitely a problem, because I haven't heard that China can produce APU."

The technician with toad mirror nodded: "well, you are right. If I remember correctly, there will be a number of Apus in the MD-82 assembly plant in Shanghai Stock Exchange."

Then the technician wearing the toad mirror suddenly became very strange: "the problem is that although the MD-82 and DC-10 use the same series of Apus, the power is very different. The MD-82 only has 96 kW, while the DC-10 needs 218 kW. What if the Chinese really get the APU of MD-82?"

The last question was told to FOSS, which made FOSS's brain AChE. It is estimated that Tengfei airlines will probably use the low-power APU of MD-82 to make up for the number.

That is to say, FOSS doesn't know that there is an old Chinese saying called "Liu a Dou who can't afford it". Otherwise, FOSS will definitely give it to Tengfei airlines.

Isn't that a joke? Think one MD-82 APU can take all models? You're kidding!

In order to catch big fish, the fisherman has to bear the occasional toss of bait. Otherwise, how can he lure the fat and tender big fish to bite?So FOSS frowned and thought about it, then tilted his head and asked, "is that 96 kW enough to start the engine?"

"This..." The technician wearing the toad mirror was speechless for a moment, but the fat technician thought for a while and said with uncertainty: "if you don't connect to other power sources, you can barely do it."

"That's fine. As long as they can start the three main engines, they will be able to repair it." In order to sell the DC-10, FOSS has a strong impulse to turn around and leave. Two technicians from McDonnell Douglas company beside him are you. Look at me and I'll look at you. They all look strange and stagnant for a while. At last, they nod their heads difficultly without conscience, which is to deal with the matter.

"En ~ ~" FOSS nodded his head with satisfaction, and immediately raised his chin: "their APU is about to be hoisted. Go and take care of it. Don't damage other equipment because of the installation of one APU."

After the two technicians left, FOSS turned and followed the simple spiral ladder into the cabin, then walked all the way to the cab, sat down in the back seat of the spare driver, and said to Hugh wood and Beckman in front of him: "as long as the replacement APU can start the engine, don't expect to provide anything extra."

Hugh wood and Beckman, who were preparing for the test, were stunned for a moment. They wanted to say something, but they could see FOSS's gloomy face and swallow what they said.

After about 20 minutes, there was a prompt from Hugh wood's walkie talkie that McDonnell technician could start the APU. Hugh wood immediately turned on the APU start switch, and the instrument screen in front of him was quickly powered on. Immediately, the rated power of the APU began to rise steadily. Beckman on one side frowned at all this, and immediately turned to look at FOSS, who was squinting behind him, Puzzled, he asked: "Mr. FOSS, the power of the APU that has just been replaced has reached 223 kW. Not to mention starting three engines, it is enough to power, ventilate and pressurize the cabin at full load."

When FOSS heard the words, his eyes suddenly opened, and he exclaimed, "what?"
