China’s Taihang engine leads the world in aircraft thrust-weight ratio


Y-20 Heavy Carrier

Y-20 Heavy Carrier

The Y-20 heavy lift aircraft will finally use the engines developed independently by China. Satisfactory progress has been made in developing them now!” said Chen Maozhang, China’s aviation engine expert and member of Chinese Academy of Engineering, with joy, confidence and pride.

According to military expert Wang Yanan’s comments, the Taihang engine can absolutely be regarded as a seed of China’s aircraft engine. Once it has burgeoned, there will be blossom of a thousand kinds of flowers.

In Chen Maozhang’s view, the comment is no exaggeration. He said: that is the significance of Taihang as a milestone. Its successful research and development mark the switch from the research and development of turbojet to that of turbofan engines in China’s development of aircraft engines.

It also promotes the realisation of the evolution from medium-thrust to large-thrust engines in China’s aircraft engine industry. When China has finished Taihang, other engines China needs in relevant areas will be developed on its basis. In this perspective, it is said that there will be thousands of beautiful flowers.

That is indeed the fact. Taihang is the power set for China’s military aircraft, but the seeds it has sown are expected to set roots and blossom in some spheres. With improvement, it can be used as the engine for major air and marine battle equipment.

Its future improved version, with large bypass ratio and enhanced thrust, can be used on bombers. The version with large bypass ratio and without enhanced thrust can be used on large transport aircraft such as the Y-20.

Ship combustion turbines derived from the Taihang engine can be the power sets for large warships such as destroyers. Just as Zhang Enhe, chief designer of the Taihe engine, said: Taihe is the third generation of the power set for fighter aircraft successfully developed by China in pursuing independent development of aircraft engines.

It has ensured supply of engines, and sped up the great-leap-forward development of China’s aviation weapon equipment.

The Taihang engine has a thrust-weight ratio of 8, i.e. the thrust it generates is eight times its weight, which is advanced in the world. Though there is much room for improvement for Taihang compared with the thrust ratio of 10 of US F-119 engine, just as Chen Maozhang said, “The research and development of an engine is a process of incessant improvement. It takes over a decade, two decades or even a longer time from the finalisation of its design to its maturity. Taihang has been making steady progress.…

Chen Maozhang said, “China is making great efforts to catch up in developing both military and civil aircraft engines. The success with Taihang will certainly shorten the time to catch up. Like the Y-20 that will be equipped with homegrown engines, China’s large airliner C919 will also have Chinese power sets.”…

Chen said, “An aircraft engine is a very comprehensive and profound technology. We have an urgent need to intensify our study of fundamental issues in developing China’s aircraft engines in order to establish a sound foundation and keep on enhancing the ability of independent creation in the industry. We shall resolve not only the problems related the types of engines we need at present, but also the problem of sustained independent development of the entire engine industry.”

Meanwhile, America’s successful experience in the sphere of aircraft engines tells us the importance of integrating production, study, research and application and coordination in creation.

He said in the end, “We must pay great attention to the change in the mode of engine development, such as from that of paying attention to the development of a certain type, to that of attaching importance to the driving force of knowledge and technology while being urged by the demand.

It is precisely due to the hope to bring about such a change that in “2011 Plan” Beihang was told to have set up a “Coordinated Creation Centre for Advanced Aircraft Engines.”

About chankaiyee2

Author of the book "Tiananmen's Tremendous Achievements" about how with the help of Tiananmen Protests, talented scholars with moral integrity seized power in the Party and state and brought prosperity to China. The second edition of the book will be published within a few days to mark the 25th anniversary of Tiananmen Protests All the parts in the first edition remain in the second edition with a few changes due to information available later and better understanding. There are also some changes for improvements of style. The new parts are Chapters 12-19 on events in China after the first edition was published: The fierce power struggle for succession between reformists and conservatives; Xi Jinping winning all elders’ support during his mysterious disappearance for 2 weeks in early September, 2012; and Xi Jinping Cyclone. Chan Kai Yee's new book: SPACE ERA STRATEGY: The Way China Beats The US An eye-opening book that tells the truth how the US is losing to China. The US is losing as it adopts the outdated strategy of Air-Sea Battle while China adopts the space era strategy to pursue integrated space and air capabilities: It is losing due to its diplomacy that has given rise to Russian-Chinese alliance. US outdated strategy has enabled China to catch up and surpass the US in key weapons: Hypersonic weapons (HGV) that Pentagon regards as the weapon that will dominate the world in the future. Aerospaceplane in China’s development of space-air bomber that can engage enemy anywhere in the world within an hour and destroy an entire aircraft carrier battle group within minutes. Anti-satellite (ASAT) weapons, anti-ASAT weapons, stealth aircrafts, drones, AEW&C, etc. The book gives detailed descriptions of China’s weapon development based on information mainly from Chinese sources that the author monitors closely. U.S. Must Not Be Beaten by China! China is not a democracy. Its political system cannot prevent the emergence of a despotic leader or stop such a leader when he begins to bring disasters to people. A few decades ago, Mao Zedong, the worst tyrant in world history did emerge and bring disasters to Chinese people. He wanted to fight a nuclear war to replace capitalism with communism but could not bring nuclear holocaust to world people as China was too weak and poor at that time. If a despot like Mao Zedong emerges when China has surpassed the US in military strength, world people will suffer the misery experienced by Chinese people in Mao era. China surpassing the US in GDP is not something to worry about as China has the heavy burden to satisfy its huge population, but China surpassing the US in military strength will be world people’s greatest concern if China remains an autocracy. US people are of much better quality than Chinese people. What they lack is a wise leader to adopt the correct strategy and diplomacy and the creative ways to use its resources in developing its military capabilities. I hope that with the emergence of a great leader, the US can put an end to its decline and remain number one in the world.

  1. A ramjet in tail section of aircraft would further increase average, overall power-to-weight ratio. The ramjet could be installed in passenger jets and in military aircraft of all types. The ramjet would ignite in normal airflow at a pre-designed airspeed, such as 400 mph. The ramjet could be supplied with pure oxygen at the air intake to cause it to ignite at a lower speed in order to supply an extra burst of thrust upon take-off from the ground or in emergencies. What do you think of this possibility?

  2. Assume thrust-to-weight ratio of 30 is possible for ramjets. So, if there are two conventional jet engines with Thrust-to-weight ratio of 8, then (8 + 8 + 30) / 3 = 15.33. So, overall thrust-to-weight ratio of such aircraft is almost doubled!

  3. I think the airplane that flew on September 18.2015 at mach 6 speed used two Wang Zhengou tubo-scram jet engines and a grapheme alloy airframe.The WS-15 and the turbo-scram jet engine does not last as long as Western engines.I think China is devoting 20 billion dollars and 100 thousand personnel to developed 3 new type of high temperature alloy,(PST Ti Al)single crystal,(Ti 45Al8Ni)Titanium-Aluminum-Niobium alloy,and Grapheme- Aluminum-Titanium alloy.
