军用航空和民用航空是相互促进的关系。比如军用运输机和民用客机之间的许多技术都是相通的，大型飞机制造基础的提升会同时促进两者的发展。就当运20走向成熟，开始装备空军部队助力战略运输能力之时，国产C-919大型干线民用客机的发展也取得突破。如果说空军装备的发展可以守卫好我们湛蓝的天空，那么国产民用机的发展则将终结国外客机独大的局面，在民航市场中打出属于中国航空的一片天地。

C919
C919客机目前已经完成了多次试航和各种测试，均告圆满成功，根据设计生产方的说法，3年内就可以投入运营市场使用。目前，凭借优秀的性能和不错的性价比，C-919已经拿下了多方总计1000架的订单。这不光有多家国内航空公司，也有一些外国的航空公司投来订单，的确吸引了世界范围内的目光。

C919
C-919在此时出现得恰当好处。我国民航市场一直在快速发展，如果任凭外国客机继续抢占可不行。根据估计，未来15年内，我国民航运营空间将达到1万亿美元之巨——约合接近7万亿人民币。C-919的成熟和大批使用，将拿回国内如此巨大的市场份额。这对于航空市场发展和国内航空工业的发展都有着重要意义。可以想象，伴随着第一批C-919投入使用，会拉开中国民航工业的良性循环：优秀干线飞机取得良好的收益，反哺民航工业，从而推出更为新式的飞机……

C-919的最大航程超过5000公里，机体很大，结构坚固，舒适性、安全性、可靠性和经济性，从测试反映的情况来看都很不错。C-919在之前的测试中使用的是欧洲制造的航空发动机。这完全可以理解，因为新飞机试飞首先要保证项目的正常进行，尽量减小变数，对于民用航空更是如此。无可否认，作为老牌航空大国，英国、法国等国的航发技术是很成熟的。

欧洲生产的客机用发动机
不过，C-919注定是要拥有一颗国产心脏，这也是客机实现真正国产化的关键一步。从去年开始，国产大涵道比大推力的民用客机发动机CJ-1000系列已经步入了发展的快车道，形成了完整的研发体系和试验平台，并在今年进行了成功的点火测试。其技术性能并不亚于国外产品，发展和研制工作也十分顺利，不久之后就可以进入实用化阶段。伴随着国产大涵道比发动机的发展，C-919迎来国产发动机已经只是时间问题。

国产大涵道比发动机取得很大进展

有些朋友还是觉得太慢了，但科技的研究不是一蹴而就的，而是需要谨慎、小心和多次的试验，航空发动机涉及到的技术是全面的：设计、金属材料、加工工业等等，任何国家的航空发动机发展都是一个漫长的过程。作为大涵道比发动机的后来者，我国在这些项目上的进展已经十分喜人。运20军用运输机、C-919民用客机的发展，都体现了我国航空工业的进步。让我们向那些奋斗的科研人员们致敬。（作者署名：军事家）

Military aviation and civil aviation are mutually reinforcing relationships. For example, many technologies between military transport aircraft and civilian passenger aircraft are connected. The promotion of large aircraft manufacturing base will promote the development of both. As Dang 20 became mature and began to equip the air force to assist strategic transportation capabilities, the development of the domestic C-919 large-scale civilian passenger aircraft also made a breakthrough. If the development of air force equipment can guard our blue sky, the development of domestic civil aircraft will end the situation of foreign passenger planes and play a world of Chinese aviation in the civil aviation market.

C919

The C919 passenger plane has completed several trials and various tests, and it has been a complete success. According to the design manufacturer, it can be put into operation in 3 years. At present, with excellent performance and good price/performance ratio, the C-919 has already won a total of 1000 orders. This is not only the case of a number of domestic airlines, but also some foreign airlines who have placed orders, which has indeed attracted worldwide attention.

C919

The C-919 has the right benefits at this time. China's civil aviation market has been developing rapidly, and it is impossible to continue to seize foreign passenger aircraft. According to estimates, in the next 15 years, China's civil aviation operating space will reach 1 trillion US dollars - about 7 trillion yuan. The maturity and mass use of the C-919 will bring back such a huge market share in China. This has important implications for the development of the aviation market and the development of the domestic aviation industry. It is conceivable that with the first batch of C-919 put into use, it will open a virtuous circle of China's civil aviation industry: excellent trunk aircraft have achieved good returns, and they have returned to the civil aviation industry, thus launching newer aircraft...

With a maximum range of more than 5,000 kilometers, the C-919 has a large body, strong structure, comfort, safety, reliability and economy. It is very good from the test. The C-919 used a European-made aero engine in previous tests. This is completely understandable, because the new aircraft test flight must first ensure the normal operation of the project, and minimize the variables, especially for civil aviation. It is undeniable that as a veteran aviation country, the aviation technology of the United Kingdom, France and other countries is very mature.

European-made aircraft engine

However, the C-919 is destined to have a domestic heart, which is also a key step in the real localization of passenger aircraft. Since last year, the domestic CJ-1000 series of large-cranked civil passenger aircraft engines with large thrust has entered the fast lane of development, forming a complete R&D system and test platform, and successfully conducted ignition tests this year. Its technical performance is no less than that of foreign products, and its development and development work is also very smooth, and it will soon enter the practical stage. With the development of the domestic large bypass ratio engine, the C-919 ushered in the domestic engine is only a matter of time.

Domestic large bypass ratio engine has made great progress

Some friends still feel too slow, but the research of technology is not done overnight, but requires careful, careful and repeated experiments. The technology involved in aero-engines is comprehensive: design, metal materials, processing industry, etc., any country. The development of aero engines is a long process. As a latecomer to the big bypass ratio engine, China's progress on these projects has been very gratifying. The development of the 20 military transport aircraft and the C-919 civil passenger aircraft all reflect the progress of China's aviation industry. Let us pay tribute to those struggling researchers.

Ang Moh engine were only used to jump start the whole project time frame without awaiting for Chinese own engines.

Just like the initial batch of J-20 combat jets 1stly used Russian engines, get their project moving and on increasingly fast momentum. Already switch to a (temporary) Chinese WS-10 engine in 2017, but not yet the fully matching (to original design requirement) WS-15. WS-15 are now only in pilot test with prototypes. Not yet finalized for actual production. Modification to design details are still expected.

This is called Chiam See Tong or 暂时顶 aka temporary substitution!

 

[3_M]

It a tall order as airlines and passengers alike are unwilling to tried an Untested engine from a relatively new player. other than this they still need to train the maintenance crew and buy new equipments.

I would think local engines will be fitted on the military version of C919.

 

[maxsanic]

I don't know whether the C919 or CR929 will succeed, but if there's going to be a credible challenger to the existing duopoly this China-Russia joint effort is probably as good as it gets. These two nations have enough combined domestic demand to lift the project to a critical mass.

Any other country attempting will likely fail as without a massive domestic market to reach minimal demand, there is no realistic way to reach economies of scale and bring down production costs even if the technology is mastered.

This bird will never get a cert to fly to US and EU.

I wonder if their own commie chink citiziens would dare fly their own aircraft if they knew the engines were local made.

good. they can use it to fly atb prostitutes all over prc to service their clients. engines won't last for 6.9 months.

Jennifer Riordan died after the engine failure on board Southwest Airlines flight 1380.

The plane was struck by shrapnel in midair as it flew from New York to Dallas yesterday.

She was a Wells Fargo bank executive and mother of two from Albuquerque, New Mexico.

Tragic Jennifer was the first passenger killed in an accident involving a US airline since 2009.

The seven other victims on Flight 1380 suffered minor injuries.

Jennifer, pictured with her husband, was raced to hospital after the emergency landing in Philadelphia What happened to her?

The Boeing 737 had just taken off from New York's LaGuardia Airport, heading to Dallas, when the left engine exploded and ruptured metal flew towards a window.

It was flying over east Pennsylvania with 143 passengers and five members of crew on board when the left engine suddenly exploded mid air.
The pilot immediately diverted towards Philadelphia to make an emergency landing and photos show what appears to be jet fuel, oozing from the passenger plane on to the tarmac.

According to other passengers on the plane, the shrapnel pierced a window next to Jennifer as the aircraft made its descent.

A retired nurse detailed the terrifying moment when shrapnel struck Mrs Riordan’s window and pulled her through the hole, almost completely sucking her out of the aircraft.

Peggy Phillips was sitting a row in front of Mrs Riordan when the engine exploded.

Ms Phillips told US network ABC despite everyone’s best efforts, Ms Riordan could not be saved.

Firefighter Andrew Needum and Tim McGinty, a ranch hand who was travelling with his wife, helped pull the woman back inside the plane.

“The window had broken and the suction, the negative pressure, had pulled her outside the plane partially,” she said. “These two wonderful men, the EMT and a passenger, managed to get her back inside the plane and we lay her down and we started CPR.”

Mr McGinty told the TV network FOX4 what happened.

“The engine went out and we had a lady go out the window, and we couldn’t pull her in,” he said. “A guy helped, we got her pulled in. They tried to resuscitate her.”

Engine on US domestic airliner explodes in mid-air, shattering window and killing woman
PHILADELPHIA • An engine on a Dallas-bound Southwest Airlines flight with 149 people aboard apparently exploded on Tuesday, forcing an emergency landing in Philadelphia as one passenger was killed after she was nearly sucked out from a window of the plane, the airline and federal officials said.
The fatality on the flight from New York was the first in a US commercial aviation accident since 2009, according to National Transportation Safety Board (NTSB) statistics.
After an engine on the plane's left side blew, it threw off shrapnel, shattering a window and causing cabin depressurisation that nearly pulled out a female passenger, according to witness accounts and local news media reports.
"We have a part of the aircraft missing, so we're going to need to slow down a bit," the plane's captain Tammy Jo Shults told air traffic controllers in audio released on NBC News.
Asked by a controller if the jet was on fire, Ms Shults responded it was not but added: "They said there is a hole and someone went out."
NTSB chairman Robert Sumwalt told a news briefing in Washington that one person had been killed, but declined to elaborate. The 43-year-old was later identified as Ms Jennifer Riordan.


She was a vice-president of community relations for Wells Fargo & Company in Albuquerque, New Mexico, and leaves a husband and two children.

"The entire Southwest Airlines family is devastated and extends its deepest, heartfelt sympathy to the customers, employees, family members and loved ones affected by this tragic event," Southwest said in a statement.

PROLONGED AGONY
It's not a couple of minutes of freaking out and frantically saying goodbye; it's 25 minutes of sustained fear that this was the end. What do you say to your pregnant wife and your parents in your final moments? That's what I was trying to figure out.
MR MATT TRANCHIN, 34.​

Flight 1380 had 144 passengers and five crew members, Mr Sumwalt said. The flight data recorder showed the plane was at about 9,900m when the engine failed about 20 minutes into the flight, according to CNN.
One passenger was taken to the hospital in critical condition, and seven other people were treated for minor injuries at the scene, said Philadelphia Fire Department spokesman Kathy Matheson.
Mr Sumwalt said the NTSB believes parts came off the engine but it has not determined if it was an "uncontained engine failure".
"There are protection rings around the engine to keep shrapnel from coming out. Even though we believe that there were parts coming out of this engine, it may not have been in that section of the engine that technically would qualify this as an uncontained engine failure," he said.

"We don't think there was a fire at all," he said.
He said the NTSB sees about three or four uncontained engine failures a year, including non-US carriers.
He added the investigation could take 12 to 15 months to complete.
Southwest said it was accelerating its existing engine inspection programme and conducting ultrasonic inspections of fan blades of the CFM56 engines on all of its 737 jets. The airline said it expects to complete the inspections within 30 days. Minimal flight disruptions may result, it said.
The death shattered an unprecedented string of more than nine years without an accident-related fatality on a US passenger airline.
The last fatal accident involving a US-registered carrier occurred near Buffalo, New York, on Feb 12, 2009, when a commuter carrier operated by Colgan Air crashed, killing 49 people on board and a man on the ground.

The NTSB shipped the Southwest plane's two black boxes, or crash-proof recorders, to its lab in Washington, where investigators did an initial download of the cockpit voice recorder on Tuesday night.
Television feeds and photos posted on Twitter show the front of the aircraft's left engine had been ripped open.
A metal piece that covers the exterior of the engine was found in Bernville, Pennsylvania, about 97km north of Philadelphia, Mr Sumwalt said.

Silent plane with no moving parts makes 'historic' flight

The blue glowing jets of science fiction spacecraft came a step closer to reality on Wednesday as US physicists unveiled the world's first solid-state aeroplane powered in flight by supercharged air molecules.

More than a century on from the Wright brothers' first artificial flight, scientists hailed the "historic" test of the new technology, which could eventually slash greenhouse-gas emissions from aviation.

Ever since Orville and Wilbur Wright's momentous glide in the winter of 1903, aircraft have been driven by propellers or jets that must burn fuel to create the thrust and lift needed for sustained flight.

A team of experts from the Massachusetts Institute of Technology managed to unlock a process known as electroaerodynamics, previously never seen as a plausible way to power an aircraft.

They were able to fly the new plane, with a wingspan of five metres (16 feet), a distance of 55 metres at a speed of 4.8 metres-per-second.

That's hardly supersonic, but the implications of this unprecedented mode of flight could be stratospheric.

"The future of flight shouldn't be things like propellers and turbines," said Steven Barrett, who designed the prototype.

"It should be more like what you see in Star Trek with a kind of blue glow and something that silently glides through the air."

At first glance, the plane itself doesn't look lightyears away from other renewable aircraft, such as the Solar Impact II craft that in 2015-16 used energy from the Sun to fly around the world.

Unlike Solar Impact, Barrett's plane doesn't have any propellers or solar panels -- or any moveable parts whatsoever.

Instead of engines, it is powered by a system comprising two main sections.

At the front of the plane sit a series of parallel electrodes made up of lightweight wires that produce an enormous voltage -- +20,000v -- supercharging the air around it and splitting away negatively charged nitrogen molecules known as ions.

At the plane's rear are rows of aerofoils set to -20,000v. The ions automatically move from a positive to negative charge, dragging with them air particles that create the so-called "ionic wind" to provide the aircraft with lift.
