Chapter 1454 Concept Debut

"Ha ha……"

Professor Wu suddenly became happy when talking about this. He said with a smile: "It went smoothly. Now they are working on the prototype."

"So fast?"

I was surprised to hear from Professor Wu that Wang Tao and Li Dong had already started tinkering with the prototype.

"How can this be considered fast?" Professor Wu felt that Zhang Qihang was a little surprised. "Our group has been deeply engaged in drone technology for many years. In the field of civil drone flight control, whether it is the flight control of unmanned helicopters or fixed-wing drones, our technology is the best. Xiao Wang and his team only need to modify the existing flight control system. How much trouble can it be?"

With the technologies that Huateng Group has acquired through years of deep research in drone development, Professor Wu believes that what Wang Tao and his colleagues are doing is just like children playing house.

At this point, Professor Wu became a little curious and couldn't help asking, "Mr. Zhang, is there something wrong?"

"Yes," Zhang Qihang replied, and did not hide it: "I have communicated with our overseas drone dealers. Everyone thinks that the drones that Xiao Wang and his team are working on, which have a payload of only two or three kilograms but are relatively cheap, have a great market. In the future, this pure electric multi-rotor drone will probably become one of our group's flagship products in the drone field."

"That's it..."

Professor Wu thought for a moment and said, "Mr. Zhang, how about you come over? It just so happens that we have basically sorted out the ideas for the long-flight UAV project. Can you come over and listen to us and give us some suggestions?"

"Alright."

Zhang Qihang nodded. He was also a little curious and wanted to see what kind of drone Shi Zhen, Zhang Jiwen, Alexander, Boris and others would make.

..............................

The entire project team attached great importance to Zhang Qihang's arrival. Professor Wu, Zhang Jiwen, Shi Zhen, Boris Svetlov, Alexander Ivanov and others even ran to the elevator entrance to greet him. This move made Zhang Qihang laugh and cry: "I say, what are you doing?"

After saying this, he looked at the old men, Boris Svetlov and Alexander Ivanov, and said with some surprise: "Mr. Svetlov, Mr. Ivanov, you look much better than before."

Zhang Qihang was not speaking against his will. Compared with the last time they met, the complexions of these old experts from the former Soviet Union who were poached by Zhang Qihang were much better. The spirit and state they displayed were completely different. Before, they looked lifeless, just like a bunch of old men who were waiting to die. But at this moment, these old men exuded vitality from the inside out. It would be an exaggeration to say that they looked 20 years younger, but it was not an exaggeration at all to say that they looked more than ten years younger.

"right?"

Boris Svetlov smiled happily when he heard this: "Of course we are happy to have a job we like."

Several old men, represented by Alexander Ivanov, nodded repeatedly with approval on their faces. Obviously, they thought so too.

As expected, ideals and goals are the best medicine to delay aging.

Zhang Qihang smiled and nodded: "As long as you don't accuse me of exploiting the elderly." Boris Svetlov was the first to jump out and expressed his dissatisfaction: "Who said I am old? I think I am very young and can still work for another 10 years!"

"Hahaha……"

Everyone burst into laughter and chatted all the way to the meeting room.

After entering the conference room, everyone's attitude became serious. Boris Svetlov, as the chief designer of the project, began to introduce this long-flight UAV project to Zhang Qihang: "After discussion, we all think that the concept proposed by you, Mr. Zhang, based on the basic aerodynamic shape of the American OV-10 'Mustang' armed reconnaissance aircraft, is very good and is the solution that best suits our current technological level.

After determining the most basic structure, we calculated and determined that installing three of our group's own six-cylinder piston aircraft engines would be enough to meet the user's requirements, and even leave a lot of room and space for subsequent upgrades."

At this point, he pressed the remote control, and the projection screen immediately showed the renderings of the drone and some general parameters:

  Overall, it is very similar to the future three-engine version of the Scorpion-A. However, due to Zhang Qihang's suggestion, the distance between the central fuselage and the left and right engine compartments has been increased a lot. As Zhang Qihang originally requested, the middle position is designed with two mounting points, and even very fashionable winglets are installed at the wingtips.

As for the mounting points, there are 12 of them, two under the main fuselage, two each on the main fuselage and the left and right engine nacelles, a total of four, and three under each wing.

In terms of parameters, since we are still in the discussion stage of the plan, all the data are just the results of rough calculations. Therefore, except for the engine, many data are expressed as "roughly" or "approximately".

Three 3-kW heavy-fuel piston aircraft engines, with a total system power of 156 kW and a total system power generation capacity of 312 kW;

Maximum take-off weight is about 5500 kg to 5800 kg;

Maximum load 1500 kg;

  The fuselage length is about 10 meters and the wingspan is about 20 meters;

The maximum flight speed is about 380 kilometers per hour, the cruising speed is about 280 kilometers per hour, the minimum flight speed is about 120 kilometers per hour, and the maximum endurance time is about 36 hours;

With a maximum payload of 1500 kg and cruising at economic speed, the maximum range is about 4500 to 4800 kilometers;

500 kg payload, economic cruising speed, maximum range of about 7500 to 8000 kilometers...

After reading these parameters, Zhang Qihang was very satisfied and nodded, "Very good, any other questions?"

Boris Svetlov said: "There are no other problems. We just need to continue to improve the details. However, Alexander and I feel that the parameters are a bit conservative. In fact, with the existing power and three engines, we can achieve a takeoff weight of 6500 kilograms."

"That's it..."

Zhang Qihang couldn't help but frown when he heard this, and then asked: "Why did the other comrades come up with such a conservative design?"

"Let me answer this question," Zhang Jiwen continued after getting Zhang Qihang's permission. "The reason why the parameters of this aircraft are set so conservatively is because this is the first time our group has made such a large drone. Everyone thinks it is safer to be conservative. At worst, we can reduce the parameters in the future."
