Most of the technologies of Qiang5G come from Qiang5E, a cooperation project between China and Italian Aerospace. +∧ Eight + ∧ Eight + ∧ Reading + ∧ Books, .※.→o

In the 80s of the last century, Hongdu Group Company signed a contract with Huaxia Aviation Technology Import and Export Corporation and the Electronic Equipment Division of the Italian Aerospace Corporation to modify the navigation and fire control system of the Qiangwu aircraft, and the two sides adopted the method of joint investment, risk sharing, and profit sharing for cooperative research and development.

At that time, the Italian side provided airborne electronic equipment and ground test equipment and was responsible for the design, synthesis and testing of avionics systems, while the Hongdu Group Company was responsible for the modification design of the aircraft structure, the trial production of prototypes and aircraft tests, which was also the first time that China adopted a joint venture method to develop military combat aircraft.

On the basis of the Qiang-5 II. aircraft, the improvement items include the design of the fuselage structure, navigation system, fire control system, weapon system, communication system, electronic countermeasures system, identification of friend or foe, cockpit environment system, electrical system, fuel system and other aspects.

The modification programme, which was originally planned to be provided by Aletosia, was later simplified to retain 17 items, and the imported equipment was connected to the eight original domestic equipment and ordnance weapon systems retained by the aircraft through two central digital computers and a dual-redundancy data bus.

In the process of cooperation, Hongdu Group has in-depth contact with the advanced avionics and aviation technology of the West, but the project is ill-fated, when the military attaches of various countries were invited to Hongdu to visit the aerobatic performance of the strong five, so that these potential customers can further understand and evaluate the performance of the aircraft, as a result, just two days before the scheduled flight show, the strong five m accidentally crashed during the rehearsal test flight, and the test pilot colonel was unfortunately killed, casting a shadow on the future of the aircraft. ∷VIII8∷Reading∷Book,.2∞≠

Subsequently, the Western countries led by Huaxia and the United States became hostile again, and the cooperation between Huaxia and Italy was interrupted.

However, Huaxia still insisted on completing all the appraisal and test flight projects.

The test flight results show that the J-5E aircraft basically maintains the original performance indicators of the J-5 prototype, the reliability of the on-board equipment and systems has been greatly improved, and the use and maintenance have also been significantly improved.

The flight speed has increased slightly, the navigation and attack accuracy has been significantly improved, the combat effectiveness is 6 to 10 times that of the Qiang-5 II, and it is no longer limited by meteorological conditions.

Although the strong 5M project was eventually aborted due to various reasons, through the cooperation with Italy, the aviation industry of China at that time came into contact with the advanced aviation technology of Western countries, and clarified the development path for the domestic modern military aircraft.

Later, the development of the strong five D is mainly based on the technology of the strong five e to add Doppler radar, navigation computer, gPs antenna, navigation processor, data transmission device and other 7 equipment, after the improvement of the aircraft has a variety of autonomous navigation methods, navigation accuracy has been greatly improved, the combat radius of the aircraft has increased significantly, since 98 years have been equipped with troops.

In recent years, Hongdu Group has carried out in-depth cooperation with first-class enterprises in communications, semiconductors and aviation manufacturing such as Huaxing Group, and has also been supported by Huaxing Group's capital, technology, engineering and technical personnel, and strong five G is one of the achievements of cooperation between the two sides in recent years.

Huaxing Group can provide the military with a very world-class semiconductor process technology, such as processors, DsP, gPu, memory chips and other core components are purchased from Huaxing Group to carry out their own wài wéi circuit design and development, which naturally makes the performance of domestic military avionics equipment reach a very high level.

Yonghan Aviation Technology Co., Ltd. is first-class in providing optoelectronic pods, display systems, on-board computers, airborne radar antennas and communication equipment in the avionics business, but the price is not very low.

In order to control costs, the airborne equipment of Hongdu Group Company uses very mature equipment from the military, and the purchased photoelectric pod and two aviation engines are the most expensive core components, accounting for about 40% of the cost of the whole aircraft.

The quotation of Qiangwu Hongdu Group Company to the domestic military is 16 million US dollars, which can be regarded as leaving enough profit space for Hongdu Group Company, and the quotation of foreign exports is more than 20 million US dollars.

The advanced training aircraft of Hongdu Group Company are now exported at 20 million US dollars, while the training aircraft of the same type in Europe and Russia are also more than 20 million US dollars, and even the old K-8 training aircraft are also 10 million US dollars.

At this time, it has become a heavy bomber's strong five G, because of the strong performance of the engine and the optimization of the aerodynamic layout, the bomb load is no worse than that of the Su-27 and F15, although the combat performance is worse, but the medium and low altitude speed is faster than these two fighters.

Because the engine is newly designed and uses some technology from some of the fourth-generation engines of Yonghan Aviation Technology, the fuel consumption is very low, and the maximum range without auxiliary fuel tanks can reach more than 5,000 kilometers.

It has the performance of a heavy bomber, but the price quoted is the price of a high-level training aircraft, which can be said to be very cost-effective.

The price of heavy fighters such as Su-27 and F15 is between 30 million US dollars and 40 million US dollars, and the domestic Flying Leopard is difficult to directly stuff the Hengshan A4 engine into it because the engine size has basically been determined, unless it is redesigned.

The strong five G is designed on the specifications of the Hengshan A4 engine size, which is almost a redesign and development of a fighter jet.

This fighter was jointly developed by Hongdu Group and Huaxing Group Company, and it is considered an internal model, and there is no need to ask the military for funds, and Yang Jie means to wait for this fighter to complete various test flights before increasing publicity.

Zhang Kelong saw this fighter at this time, and learned that this fighter was conducting weapon target experiments, and he said happily: "You really have made several big killing weapons quietly!"

He looked at Yang Jie and said: "However, this photoelectric pod produced and provided by Yonghan Aviation Technology Company is too advanced to be exported." ”

Yang Jie smiled: "Of course, we also produced the monkey version of the photoelectric pod, the export type photoelectric targeting pod is composed of forward-looking infrared detection system, high-resolution camera, laser irradiation ranging system and other devices, the overall detection distance is controlled at 20 kilometers, the laser laser system works at 1.06 microns, the maximum range is 18 kilometers, and the irradiation distance is about 12 kilometers. ”11
