"Chief Engineer Li, the supporting production of all parts and components has been completed?"

Yang Jie asked at this time. (5) ∞ eight (5) ∞ eight (5) ∞ read (5) ∞ books, .←.o≈

Generally speaking, before assembly, it is necessary to match the required parts, Yang Jie knows that the research and development progress of the parts required for the engineering prototype is not the same, and the matching of the parts is not necessarily complete.

"The matching of various parts is basically completed. However, in terms of airborne equipment, terahertz synthetic aperture radar is temporarily lacking. ”

Li Jianwu said.

For example, terahertz synthetic aperture radar is developed and manufactured by a radar research institute under Huaxia Electric Technology Group Company, but the core transceiver module, high-power devices and high-speed switches of the radar core are provided by a subsidiary of Huaxing Group Company, and this research institute is the best in China in terms of radar imaging algorithms.

"Yang Shao, this radar thing is temporarily vacant, but it has also been implemented, and they will be sent to our company next week, which will not affect the assembly of the engineering prototype. ”

Li Jianwu said.

Yang Jie nodded in satisfaction.

In the afternoon, Yang Jie, Zhang Kelong and others came to the painting workshop.

This engineering prototype enters the paint shop for painting, which uses an advanced digital automated coating system, and the spray qiāng on these robotic arms is uniformly sprayed on these fuselages and wings under the control of computer programming.

The entire painting process is not only fast, but also of excellent quality.

Because the robots of Dawn Machinery Factory have been used in automobile factories and consumer electronics factories on a large scale over the years, they have been very mature, and Huake Aviation Technology Company naturally wants to use them.

Because the stealth paint needs to be applied several times, and the temperature at which the coating is baked is different, it takes several days to complete the painting. ∵ Eight ∵ Eight ∵ Read ∵ Books, .↗.▲o

The stealth material of the "Shadow" drone is very advanced, covering the surface of the fuselage like a thin layer of varnish, and after each layer of paint, technicians also need to take instruments to measure the thickness and uniformity of the paint.

Zhang Kelong saw that the coating of the fuselage stealth paint was not thick, and even some rivets and screws were clearly visible, and some gaps could also be seen, so he couldn't help but say: "Your paint is much thinner than the stealth paint developed by a domestic research institute, and the paint can reach a centimeter thick after the coating, and the paint is very heavy." ”

Yang Jie knows that the stealth paint developed in China uses iron oxide absorbing materials, and the paint contains a large number of iron atoms, so the paint is very heavy.

However, Huaxing Group uses silicon carbide absorbing materials, which contain conductive polymer materials, which can quickly convert electromagnetic waves irradiated by radar waves into electrical energy for conduction.

"There are many kinds of absorbing materials, and now there is no kind of absorbing material that can achieve the best effect on any waveform of electromagnetic waves, and we have been forced to carry out research and development in order to develop absorbing materials for dark wave chambers, and we have done a slightly better job in absorbing materials for microwave radar waveforms. ”

Yang Jie said.

"Looks like I'm going to be here a little longer. ”

Zhang Kelong looked at Yang Jie and said, "You actually made a prototype for such a major thing to tell me, it's really calm!"

"This is also to surprise Minister Zhang and the leaders!"

Yang Jie laughed.

Song Fuxiang next to him glanced at Yang Jie with a smile, he knew that Yang Jie had never thought of asking for R&D funds from the military at the beginning of the research and development of this stealth drone, and these R&D funds were all allocated by the head office, and they were completely internal R&D projects of the company.

"Hehe, this surprise is really big enough!"

Zhang Kelong smiled, and then said to Song Fuxiang: "Hongdu Group Company has really accumulated a lot of technical strength over the years, and I want to investigate and understand your group company during this time." ”

"Welcome to Minister Zhang's inspection and understanding!"

Song Fuxiang said with a smile.

The next day, Zhang Kelong also inspected the production line of the training aircraft and the attack aircraft of Hongdu Group Company, and Zhang Kelong especially focused on learning about the latest type of strong five G known as the "zhà dàn truck".

This strong five G has been modified in the shape of the airfoil and air intake, while taking into account the ultra-low-altitude assault bombing, it can also perform high maneuverability at high altitude, no longer emphasizing ultra-low-altitude penetration, but emphasizing precision strikes, the size of the fuselage is one larger than the previous model, the empty weight has reached nine tons, the internal oil volume has reached five tons, the maximum take-off weight is more than twenty tons, and the largest external weapon can reach eight tons!

The most important thing for Qiangwu G to have such a large loading capacity is that it is equipped with Hengshan A4 engine, which is the fourth engine of the small bypass ratio turbofan engine launched by Yonghan Aviation Technology Company, and the thrust of the engine can reach 14 tons without afterburner!

Yonghan Aviation Technology Co., Ltd. is very mature in the fourth-generation engine technology, and one of the fourth-generation engines is undergoing technical verification tests, so the third-generation engines like Hengshan A4 also use some new technologies, and the performance of the engine is extremely good.

It is in response to the words of Lida Brick Flying, the thrust-to-weight ratio of these two engines has reached an astonishing 1.4, and the performance exceeds that of the third-generation engine of the same type in the United States, and the strong five-G level flight speed of two Hengshan A4 can reach Mach 2.5!

Now the domestic aviation thrust-to-weight ratio is generally not more than 1, the previous old model of the flying leopard engine thrust-to-weight ratio is even 0.7 is difficult to achieve, more importantly, the quality of Hengshan A4 engine is very reliable, whether it is Hengshan and Kunlun series of different types of engines are very stable and reliable.

Comparatively speaking, the most advanced Qiang-5M of the Qiang-5 series has an empty weight of six tons, and the maximum take-off weight is twelve tons, the aircraft is in a state of no external plug-in, and the maximum level flight speed at an altitude of 11,000 meters will only reach Mach 1.2, carrying two tons of external load, and the maximum combat radius is 400 kilometers, which can be said to be a very short leg.

This is mainly because the previous Qiangwu was equipped with the third model of the turbojet turbojet-6A engine of Dawn Aviation Development Company, with a single static thrust of 3 tons and an afterburner of 3.75 tons, the thrust can be said to be very small, and the overhaul life of the engine is only 150 hours.

Since Hongdu Group began to purchase different types of engines from Yonghan Aviation Technology Company, the performance of the training aircraft and the attack aircraft produced by Hongdu Group has been qualitatively improved!

It is with the blessing of the high-thrust engine of Yonghan Aviation Technology Company, and now Hongdu Group Company has made a lot of money with Huaxing Group Company, and now it has begun to let go of itself, and cooperates with Huaxing Group Company to continuously develop new flight platforms and weapons.

At this time, Zhang Kelong saw that there were more than 22 external solutions for the 12 external attachment points under the belly and wings of this Qiangwug that were not part of the attack aircraft, and that the optical pod was installed, and he couldn't help but Song Fuxiang said: "You guys have changed their guns this time!" 11
