COMAC C919

But China can sell to Iran the AVIC AG600 large sea plane though. I believe the majority of those technology are Chinese design and made.

My bad, I had mistaken it for C919. I believe the AG600 can be produced with just domestic industry. The plane will have military uses.

From reports, the AG600 is 95% domestic in terms of value. The core components including engine are all domestic. C919 is expected to be 90% domestic by 2025.

I read somewhere that CJ-1000 is the civilian variation of WS-20. Is there any modifications that must be done to a military engine to be able to equip a civilian plane?

I heard different story that WS-20 is based on WS-10's core. WS-20's civilian designation is SF-A, it is closer to CFM-56 (which is claimed to be the inspiration of WS-10 core) in performance, so a conservative but easier reach. CJ-1000 is aiming at Leap, a much recent advanced target, a different story.

Fuel economy and noise reduction are the primary issues to be addressed for a military engine to be used for civilian plane.

This is corect.

According to this article, the CJ-1000AX demonstrator engine has been fired up for the fist time.

Great but I hope it doesn’t become a white elephant

No question the military break through with WS series is now helping the civilian sector

COMAC taking steps toward a future CFRP wing for the C919.

COMAC taking steps toward a future CFRP wing for the C919.

In the tweet:

Recently, a full-size wing box section was rolled off the assembly line as part of #COMAC's composite wing project, which intends to create a viable technical resource pool for future development of the #C919. The prototype will now undergo design inspections.

It seems the emphasis is not so much the achievement on the rollout but rather the building up on a technical resource talent pool for the future. Sensible long term planning.

Yes - hence "steps toward" and "future". It's not going to enter service with a CFRP wing.

However, I expect COMAC will eventually want to base an aircraft family on the C919, with shrink and stretch derivatives. The stretch model in particular may require substantial modifications to the wing design (as with the A321 flap system compared to the A320), so the efficiency benefit might justify a clean sheet, CFRP development. Especially since by then it could end up competing at the lower end of the MoM segment against Boeing's optimized NMA.

So the orders for the C919 have exceeded 1,000, while those for ARJ21 over 500 now. Not bad.



SHANGHAI (Reuters) - Chinese conglomerate HNA Group [HNAIRC.UL] has agreed to purchase 200 C919 and 100 ARJ-21 planes from the Commercial Aircraft Corp of China Ltd (COMAC), the companies said on Saturday.

HNA and COMAC said in a statement that they had signed a strategic cooperation under which HNA had agreed to introduce and operate the jets in China and in overseas markets such as Africa over an unspecified period of time.

It did not disclose financial terms or say whether these were firm orders or options.

The Chinese conglomerate, which has been selling assets to raise cash, holds stakes in over ten airlines, including Hainan Airlines (), Capital Airlines and Africa World Airlines in Ghana. It signed a deal for 15 C919 planes in 2010.

HNA said it had signed the deal to support the development of China’s aviation industry as well as Beijing-led “Made in China 2025” and Belt and Road initiatives, it said.

The C919 aircraft is a symbol of China’s ambition to muscle into a global jet market estimated to be worth $2 trillion over the next two decades, as well as of Beijing’s broader “Made in China 2025” plan to spur home-made products, from medicines to robots.

The state planemaker sent the C919 narrowbody plane on its maiden flight last year and obtained approval to begin mass production of the ARJ-21 regional jet last July.

In February, COMAC said its total order book for the C919 jet was 815 aircraft, while orders for the ARJ21 stood at 453.
