**FOREWORD**
With the continuous development of science and technology, the upgrading of military equipment is also an eternal topic. In order to safeguard national security and interests, all countries are sparing no effort to develop their national defense military strength, and the advanced degree of military equipment is a top priority. As one of the important manifestations of military strength, the performance of fighters and bombers is directly related to the strength of a country's air force. And for these aircraft to perform well, engines and stealth technology are undoubtedly crucial.
Recently, some news about China's military equipment has attracted widespread attention, including news about the J-20 fighter and the H-20 bomber. It is reported that China's J-20 fighter will be equipped with a domestic turbofan 15 engine and adopt the world's leading metamaterial stealth technology, while the H-20 bomber will also use a turbofan 15 engine, which is expected to become the world's first stealth strategic bomber with supersonic cruise. As soon as these news were exposed, they immediately attracted the attention and heated discussions of the international community.
**1. China's military equipment has added new highlights**
Recently, the Chinese military announced an important news about the list of commendations for the turbofan 15 engine. From this list, we can see the name of Cheng Ronghui, the chief designer of turbofan 15, who was successfully selected for this commendation list by virtue of his outstanding contributions in the field of engine design.
As we all know, the turbofan 15 engine is an advanced aero engine independently developed by China, and its comprehensive performance has reached the international leading level. According to relevant data, the thrust of the turbofan 15 engine has reached 18.5 tons, which not only surpasses similar foreign engines, but even surpasses the American F119 engine and becomes the first in the world.
At the same time, the turbofan 15 engine also adopts a new large bypass ratio design, which can not only improve the fuel economy of the engine, but also effectively reduce the air resistance of the aircraft and improve the overall performance of the whole aircraft. It is precisely because of such advanced aero engines that China's military equipment can shine internationally and gain more and more recognition and praise.
**Second, the application prospect of turbofan 15 engine**
The successful development of the turbofan-15 engine not only provided strong power support for the continental's fighters and bombers, but also pointed out a correct path for the development of the continent's aviation industry. It can be said that the successful research and development of the turbofan 15 engine is of great strategic significance to the continental, which will completely break the technical blockade of foreign aero engines on the continental, and let the continent have more voice and dominance in this field.
In the design and application of aero engines, there has always been a very important parameter, that is, the bypass ratio. In general, large bypass ratios are suitable for use in airliners and transport aircraft, while small bypass ratios are more suitable for fighters, bombers, and attack aircraft. The turbofan 15 engine is a high-thrust engine in the small bypass ratio engine, and its performance advantages are very obvious, which will bring a new flight experience to China's J-20 and H-20 aircraft models.
It can be said that the successful advent of the turbofan-15 engine will have a far-reaching impact on the mainland's military equipment strength. First of all, in the application of fighters and bombers, the turbofan 15 engine can provide more powerful power support for these aircraft, which can not only improve the climb performance of the aircraft, but also improve the supersonic cruise capability of the aircraft, so that these aircraft can respond to various complex combat environments more quickly and flexibly during combat.
Secondly, in the development of stealth fighters, the turbofan 15 engine can also play a very important role. With the increasing number of stealth fighters, how to ensure the stealth performance of stealth fighters in the take-off and acceleration stages has always been a very big challenge. The stealth fighter using the turbofan 15 engine can effectively avoid exposing the true position of the stealth fighter by adjusting the sweep angle and taking off with high thrust, ensuring that it is always in a stealth state, which brings greater difficulties to the enemy's reconnaissance and interception.
**III. Comprehensive Strength of China's Military Equipment**
The successful advent of the turbofan-15 engine and the upgrading of related military equipment have once again demonstrated the mainland's strong strength and profound attainments in the field of military science and technology. Whether it is engine technology or stealth technology, the mainland has stood at the forefront of the world and has gradually become a leader in military equipment innovation.
In terms of engine technology, Continental can not only independently develop large bypass ratio turbofan engines, but also successfully develop small bypass ratio turbofan engines, and has made a series of major breakthroughs and achievements in this field. It can be said that the continent's aero engine technology has reached the international leading level, which has laid a solid foundation for the mainland's military equipment upgrading and international market development.
In terms of stealth technology, the mainland is also actively exploring and innovating, and has made a series of major breakthroughs in the research and development and application of metamaterials, and has successfully developed metamaterials suitable for aircraft manufacturing, providing a new choice of stealth materials for the mainland's stealth fighters, making our army's stealth fighters more difficult to be detected by enemy radars, and having stronger stealth capabilities and survivability.
It can be said that the mainland's military equipment has gradually realized a gorgeous turn from following to running and then to leading, whether in the field of engine technology or stealth technology, the mainland has begun to surpass some developed countries and become a real military equipment innovation power. In the future, the mainland will continue to increase investment and innovation in science and technology, promote the in-depth integration of military science and technology, and bring more surprises and bright spots to the development of military equipment on the mainland.
Fourth, the international status of domestic military equipment**
With the continuous improvement of the mainland's military equipment strength, more and more domestically produced military equipment has begun to go abroad, which has been widely recognized and favored by various countries. In particular, in some technologically advanced military equipment, such as stealth fighters, aircraft carriers, high-precision weapons, etc., China's domestic military equipment has begun to gradually emerge and has become a popular darling in the international market.
Among them, the J-20 fighter, as the mainland's fifth-generation stealth fighter, has made a great breakthrough and improvement in performance and configuration, and has begun to gradually move towards the international market, and has been favored and purchased by some countries. The turbofan 15 engine and metamaterial stealth technology undoubtedly provide a strong backing for the export of the J-20 fighter, making this fighter more competitive and attractive in the international market.
In addition, there are some other domestic military equipment that has also received widespread attention from the international community, such as China's hypersonic weapons, air defense and anti-missile systems, long-range unmanned aerial vehicles, etc., which have begun to gradually move towards the international market, providing countries with more national defense and security options. It is believed that with the continuous popularity of these domestically produced military equipment, the mainland's international status and international influence will also be further enhanced, injecting strong impetus into the in-depth development of China's military diplomacy.
**Epilogue**
The development and upgrading of military equipment is not only a manifestation of comprehensive strength, but also a stage for scientific and technological innovation, and the reason why China's military equipment has been able to achieve such brilliant achievements is inseparable from the hard work of the vast number of scientific and technological workers and the strong support of the state.
