Early Thistle Yan Chunqiu

Tang Changhong, the chief designer of China National Games-20, said in an interview with CCTV Oriental Time and Space column recently that the Yun-20 has officially produced in mass production.Earlier, Tang Changhong has revealed that Yun-20 will replace Chinese domestic engines this year.Chinese military scholar Du Wenlong said yesterday that the production capacity of the transportation-20 will not be restricted by the engine, and the Yun-20 will quickly enter the pulse production stage.

The Yun-20 is also called Kunpeng. It is nicknamed Fat Girl. It is a new generation of heavy multi-purpose transport aircraft independently developed by China. The maximum take-off weight is 220 tons. Under complex weather conditions, it can perform long-range aviation transportation missions of various materials and personnel.The shipping-20 transport aircraft first flight in January 2013, the first batch of the Air Force in June 2016.

Compared with the famous J-20 stealth fighter, Yun-20 does not seem to be so attractive, but its significance for the Chinese military is no less than the J-20.For a long time, fast remote delivery capabilities have always been the weakness of the Chinese military, and the Yun-20 may fundamentally change this situation.

In addition to performing delivery personnel equipment tasks, Yun-20 is also a platform for developing large-scale early warning aircraft, tankers, and electronic reconnaissance machines.Once the problem of localization of the engine is solved, the research and development and production of Chinese military aircraft will no longer be subject to people.It can be said that the mass production of Yun-20 will truly enable China to enter the strategic air force threshold with both offense and defense.

However, which domestic engine will be used for Yun-20 is still unknown.The Yun-20 prototype uses the D-30KP2 engine imported from Russia.It is reported that Yun-20 may use the turbofan-18 engine of Chengdu Engine Co., Ltd. to imitate the D -30KP2 turbofan-18 engine, and may also use a more thrust-20 engine.The turbofan-20 engine is the Big Channel Black Fan engine developed by China on the basis of Taihang engine.Once the engine is installed, it marks that the Chinese aviation industry will overcome the constraints of engines and enter the fast lane for development.

For a long time, aviation engines have been the biggest resistance to the development of the Chinese Air Force.In recent years, China's domestic aviation engines have made rapid research and development. Although there is still a large gap compared with the United States and Russia, it is using the advantages of the national system to strive to catch up and achieve new breakthroughs.For example, the first fourth-generation stealth fighter-20 in China has begun to equip the domestic turbofan-15 engine.

At the Zhuhai Air Show in November last year, the Chinese-made J-10B fighter equipped with a turbofan-10B vector engine showed the flying stunt and other flight stunts such as the maneuverability of the cobra, which aroused the attention of the outside world.

J-20 chief designer Yang Wei asked about whether the J-20 was equipped with a domestic vector engine or not asked: How do you know that the J-20 is not available (domestic vector engine)?This shows that the turbofan -15 engine already has the conditions for mass production and equipment, and the J-20 with a turbofan-15 vector engine may be unveiled this year.

In addition to the J-20 and Yun-20, the Chinese Air Force also has a 20s that have also appeared, that is, straight-20.

When the Wenchuan earthquake occurred in May 2008, the helicopter available for the Chinese army was very limited, which seriously affected the disaster relief effect.Since then, although the R & D equipment of China's helicopter has made significant progress, it still lacks a general helicopter with excellent plateau performance, and the Navy does not have a medium -sized helicopter.The emergence of direct-20 universal helicopters will significantly improve this situation.

The size and layout of the direct-20 medium-sized general-purpose helicopter are closer to the American Black Eagle helicopter, but it is not simply copied by the Black Hawk helicopter.Unlike the black eagle's four-leaf paddle main rotor design, the straight-20 uses the five paddle structure, which has good control and maneuverability, and the shape details are also significantly different from the Black Eagle.At the same time, Zhi-20 uses two new generation of 1600 kWh's turboshaft engine independently developed by China, marking that China's domestic helicopter power system has reached the international mainstream level.

According to online news, Zhi-20 has begun mass production and is expected to be installed this year.According to Du Wenlong's analysis, the development direction of Zhi-20 is to go to the mountain, the sea, and series.Implement tasks such as reconnaissance, patrol, anti -submarine, and supply.

The last 20 of the Chinese Air Force was the H-20 that has not yet officially debuted.In May last year, during the departure of China Aviation Industry Group Co., Ltd.'s propaganda film, a large aircraft with a flying-wing layout was mysterious. It was speculated that it was a new long-range strategic bomber-20 in China.

Chinese military scholar Yin Zhuo believes that the Board-20 will compare with the US B-2 strategic bomber and have stealth performance.China's development strategic bomber has the experience of developing J-20 and F-31 stealth fighters, so there is no major problem in materials and design.In addition, China has developed large aircraft such as Yun-20 and C919, and related technical reserves are also useful for developing strategic bombers.

It is reported that the Boom-20 is in the test stage on the iron bird experiment stand. The iron bird test platform is mainly to verify the flight control system, the lifting rudder system, the direction of the rudder, etc. of a new aircraft.It is also the most important step. Once the test stage of the iron bird experiment table is entered, it means that this aircraft is not far from the first flight.

In just a few years, the four 20 years of the Chinese Air Force have been released, which is the epitome of the rapid development of China's military industry.It is foreseeable that with the improvement of comprehensive national strength, China's military power will continue to increase.How to adapt to this trend will be a topic that needs to be faced in the Asia -Pacific region and even the world.
