The Hailong helicopter is the largest heavy transport helicopter developed in China, and it is independently developed, and the military attaches great importance to it, especially the navy is very urgent for this aircraft.

In fact, the Hailong helicopter is an upgraded version of the previous Super Flying Cat heavy helicopter of Ruisheng Technology Company, because the previous Super Flying Cat had an accident in which the motor lost power in the air and crashed during the test flight, resulting in a fatal accident, so the Super Flying Cat project was also stopped.

The money that Yang Jie smashed into the Super Flying Cat before was also lost, and he lost a lot of money.

In the subsequent investigation, it was found that the power system malfunction caused the accident, mainly because this super flying cat used too much new technology in the power system, and there were serious problems during the test flight.

To this end, Yang Jie also personally told the military top brass that Ruisheng Technology Company will definitely learn a lesson and work hard to solve the problems of Super Flying Cat.

This incident also caused a big blow to the R&D team of Ruisheng Technology Company, Yang Jie also realized that there is still a lack of complete and necessary technical testing and verification facilities in China after the investigation of the cause of the accident, and many models have problems in the test flight process before This is also the reason, so there is the existence of this complete technical testing and verification center.

The project of Super Flying Cat is considered yellow, but the technical experience accumulated by this project has also been retained.

After several years of painstaking research and development, the technical team also found that the reliability of high-temperature superconducting motors in some harsh environments is higher than that of permanent magnet motors, so they began to use this type of motor on Hailong helicopters.

Of course, the Super Flying Cat helicopter has also been replaced with a power system and fully optimized after being grounded for a few years, and this year the helicopter has also begun to carry out go-around test verification.

After optimization, the adjusted platform of the Super Flying Cat is one size smaller than the Hailong helicopter, positioned in the 20-ton helicopter, and its performance is higher than that of the Da Mao Mi-171.

However, before the completion of the test flight, the military is still constantly purchasing Mi-171 from Da Mao to meet the needs of the army, and Da Mao also provides parts to the domestic military for domestic assembly.

Yang Jie also knows that the Super Flying Cat can only gain the trust of the military after passing a long test flight mission, but he is not particularly worried about this.

The rotor system and power system of Ruisheng Aviation Technology Co., Ltd. have been very mature in technology through so many years of research and development and military use, and the power consumption, weight and reliability are much higher than these turboshaft engines of Damao.

It can be said that the helicopter below the 20 tonnage level is not a problem in technology, but it is mainly the introduction of imitation and some mature models, and many technical patents are more controlled in the hands of these parts suppliers.

The Helicopter Research Institute has not applied for many patents because of military secrets, but Huaxing Technology Group Co., Ltd. has helped the Helicopter Research Institute to continuously apply for technology patents in China over the years, and has also applied for patents in overseas countries, and now the annual patent applications have increased by more than 20% per year, and most of them are invention patents.

Ruisheng Aviation Technology Co., Ltd. and Helicopter Research Institute dominate the number of patents in the two key models of Super Flying Cat and Sea Dragon helicopter and their pre-research results, especially in the fields of electric rotor system and fuel cell, flight control and avionics technology.

Rabbit in the eighties of the last century from the Gallic chicken to introduce several models such as dolphin helicopters for so many years, from the Gallic chicken procurement parts assembly to the domestic part of the manufacturing to all the manufacturing, to now finally eat through the technology of these models.

After the launch of the project of developing the Super Flying Cat, Ruisheng Aviation Technology Co., Ltd. has independently developed and designed key equipment technologies such as aerodynamic layout, electric rotor system, flight control, and avionics equipment.

Although the Super Flying Cat project suffered a great setback, it was still not interrupted, and continued to play in front of the walk, and now it is tinkering with the Sea Dragon helicopter.

Of course, being able to get to this point is also related to the accumulation of helicopter technology in China for so many years, and it would not have been possible without these.

The next day, Yang Jie also inspected the helicopter production line of Ruisheng Aviation Technology Company.

The newly built production line has only more than 100 people because the production task is not heavy, but they are all experienced technicians and engineers.

However, the processing equipment equipped with the production line is the most advanced equipment, including high-precision machining center CNC machine tools, CNC ignition machine tools and other equipment, which are used to process high-precision parts.

The workshop also includes hot isostatic vacuum sintering furnaces, vacuum brazing furnaces, laser processing equipment, 3D printing equipment, etc.

The technicians and engineers in the workshop are all trained by Huaxing Technology Group Company itself, and these technicians have had a long time of work experience in similar positions before.

The production materials of the blank workshop are mainly metal, composite materials, plastics, plexiglass, etc., and the production products include skin, attached plates, clips and other components and parts, while the machining workshop is mainly medium-sized and large-scale comprehensive machine tools, which can produce components of different sizes from bolts to helicopter fuselage lattice frames and wheels.

Despite the small number of employees, the plant is highly digitally automated and fully equipped to allow the helicopter fuselage structure to be prototyped from start to finish.

At present, in addition to the prototype of helicopters, the main business is also responsible for the production of electric propeller systems and the production of various helicopters of some Changhe Aircraft Manufacturing Company.

After all, Changhe Aircraft Manufacturing Company is also the major shareholder of Ruisheng Aviation Technology Company, and now the production tasks of Changhe Aircraft Manufacturing Company are also relatively heavy, and it is also divided into part of the production capacity.

Changhe Aircraft Manufacturing Company is very envious of so many advanced equipment and processing technology of Ruisheng Aviation Technology Company, because these technology patents of Ruisheng Aviation Technology Company are shared with other sub-group companies, and any new technology patents can be used immediately, and the speed of technology upgrading is extremely fast.

To this end, Changhe Aircraft Industry and Hafei are constantly introducing new equipment and technology from Huaxing Technology Group Company.

Of course, Yang Jie then inspected the R&D center of Ruisheng Aviation Technology Co., Ltd., especially the research and development of a large number of cutting-edge technologies such as helicopter autonomous piloting technology, maglev flight technology, bionic flapping wing flight technology, and autonomous obstacle avoidance flight technology.
