New generator unit application assists China’s future warship developmentChina Ocean Shipping Magazine
Today 10:31
[New aircraft carrier power! 704th Institute 20MW class marine steam turbine generator sets passed appraisal]
On December 4th, the 20MW class marine steam turbine generator set independently developed by 704th Institute and possessing complete intellectual property rights passed the scientific and technological achievements appraisal and became the domestic marine steam turbine generator set with the highest power level. Ma Weiming, academician of the Chinese Academy of Engineering, He Lin, academician of the Chinese Academy of Engineering, and experts from relevant domestic institutions served as members of the appraisal committee. Gao Xiaomin, director of the 704th Institute, and Zhao Yueping, assistant to the director, attended the appraisal meeting.

China's domestically developed 20-megawatt turbo generator unit has been put into actual use for the first time. It is widely expected to be used on China's future warships to support the advanced integrated electric propulsion (IEP) technology that would enable the use of high energy weapons, including electromagnetic railguns and lasers.
The ship-use 20-megawatt gas turbo generator unit, independently developed by the No. 704 Institute of state-owned China State Shipbuilding Corporation (CSSC), was recently put into application, reads a statement the institute released last week.
The statement did not specify what kind of ship the new generator unit was installed on, and the generator unit's designation remains undisclosed.
In December 2018, this type of generator unit passed technical appraisal, the No.704 Institute announced in a statement at that time. It said that it is the most powerful ship-use turbo generator unit in China, and 20-megawatts of power is four times as much as China's current generator units and is on par with the most advanced generator units developed by the US and European countries.
The new turbo generator unit will lay the foundation for a future IEP system for ships, making it of significant military value, the institute said.
US' Zumwalt-class guided missile destroyer uses two 36-megawatt generator units, which allows it to reach a top speed of 30 knots at a displacement of 15,000 tons, Ordnance Industry Science Technology, a Xi'an-based magazine on the national defense industry, reported on Monday.
By this calculation, two 20-megawatt generator units of this kind would be able to power China's next generation large frigate that potentially has a displacement of 5,000 to 6,000 tons, and three to four would be enough to drive China's 10,000 ton-class Type 055 destroyer, the report said, noting that China's new generation submarine could technically also use the new generator unit.
The biggest value of the new generator is its potential application in an IEP system, which could more efficiently store and allocate power, analysts said.
Beijing-based naval expert Li Jie told the Global Times that high energy weapons including electromagnetic railguns and lasers as well as electromagnetic catapults for aircraft carriers consume large amounts of electricity in a short period of time, and an IEP system, realized by the generators, would be able to provide stable power to allow them to operate.
China is reportedly developing an electromagnetic railgun, and analysts speculate it could be installed on an upgraded version of the Type 055 destroyer in the future.

China recruits more pilots for carrier-based fighter jets
Source Global Times. Editor Wang Xinjuan. Time 2020-08-11 01:02:00
About 16,000 people signed up for the Chinese People's Liberation Army (PLA) Navy's recently completed annual pilot recruitment drive, and among those who have passed the tests to become pilot cadets, nearly half will be trained to fly aircraft carrier-based fighter jets in the coming years. This is expected to satisfy China's future aircraft carrier programs.
Experts said on Monday that the ratio indicates China's ambitions in aircraft carrier development, as the country could operate three or more aircraft carriers in the near future, which need more pilots.
The PLA Navy recently wrapped up the 2020 pilot recruitment drive, during which none was infected by the novel coronavirus, thanks to nucleic acid testing and optimized procedures, China Central Television (CCTV) reported on Sunday.
A large batch of talent among the 16,000 registered applicants emerged after several selections, the report said, without elaborating further on the number of applicants who were eventually enrolled in the pilot training program.
Chu Hanqiang, director of the PLA Navy Pilot Recruitment Office, was quoted as saying in the report that 49 percent of the enrolled candidates will become aircraft carrier-based fighter jet pilot cadets, and this should satisfy the development of aircraft carriers.
"In the past, most Navy Aviation Force pilot cadets were trained to fly ground-based fighter jets and bombers," Li Jie, a Beijing-based naval expert, told the Global Times on Monday.
The significant increase in the ratio for aircraft carrier-based fighter jet pilot cadets indicates that China will operate not only two aircraft carriers, Li said.
Forbes reported in July that China's third aircraft carrier is being assembled in a dry dock in Shanghai's Jiangnan Shipyard. Military observers expect the new aircraft carrier to be much larger and carry more aircraft than China's previous two, the Liaoning and the Shandong.
Cadets will study for four years and potentially continue to train on advanced trainer aircraft, the website of the Navy's pilot recruitment program said.
This means this batch could join active service when the third aircraft carrier is commissioned, observers said.
Li said that in addition to aircraft carrier-based fighter jets, the PLA Navy also needs more pilots for vessel-based helicopter pilots, as China recently launched two Type 075 amphibious assault ships and each has the potential to carry about 30 helicopters.
Other warships, including Type 055 and Type 052D destroyers, also host helicopters, Li noted.
