Japan's first stealth fighter jet test: 'extremely stable'
By Thom Patterson, CNN

• Japan's tests the nation's first stealth technology jet
• The X-2 test pilot described the flight as "extremely stable"
• It's the latest example of Japan's assertive defense posture

(CNN)Japan joined the exclusive stealth jet club Friday with the successful test flight of its first radar-evading aircraft -- a prototype called the X-2.

The test pilot described the flight as "extremely stable," according to manufacturer Mitsubishi Heavy Industries.
The twin-engine jet -- painted in the national red and white colors -- took off from Japan's Nagoya airport and completed various test maneuvers including climbing, descent and circling.
It then touched down at Japan Air Self-Defense Force's Gifu Air Base, Mitsubishi said. The pilot said the flight mirrored simulated training.

The historic event is the latest example of Japan's assertive defense posture in the region, as China's military continues to flex its muscles, with a 7.6% increase in its 2016 defense budget.
Beijing's Shenyang FC-31 fighter jet appears to have stealth characteristics, but few engineering details are known about it. China's fifth-generation twin-engine J-20 fighter is also thought to be a stealthy design and is expected to be fully operational by 2018.
Japan's development of a stealth fighter jet will add another component to an already complicated security environment. World leaders are concerned about tensions on the Korean peninsula and territorial disputes in the sea lanes running south from northern Asia. With all this going on, Washington has to remain mindful that Japan hosts most of the key U.S. forward bases in the region.

The Japanese X-2 that flew Friday "integrates an airframe, engines, and other advanced systems and equipment all adaptable to future fighters" Mitsubishi said.
The engineering of radar-evading stealth technology remains challenging even now, decades after the United States first invented it. Specific surfaces of the planes are designed to absorb radar signals or to deflect radar signals away -- making the aircraft virtually invisible to electronics. Special coatings are applied to exterior surfaces that make the planes even less detectable by devices. The U.S. F-117 Nighthawk (no longer in service), B-2 Spirit bomber, F-22 Raptor and F-35 Lightning II fighters all have stealth designs.

It is only a test bed and not even prototype. somebody is pitting too much hope.

Who lied

China just adopted 6 blades to old design of 4 blades, after this !!!
As we know, Y-9 learn much from C-130J

 

[William Hung]

Wow this thread is about an interesting news on Japanese aviation unrelated to anything about China, but Chinese member still jump in to talk about China’s aviation and makes comparison between China and Japan? are Chinese members that jealous and insecure towards Japan to such an extent? Chinese members, please control your emotions and becareful of what you posts, don’t allow other members to read your posts and make a bad judgement of your people’s characteristic. Chinese posts in this thread now make your people look very insecure and jealous. Stop doing this.

You are comparing orange to Apple. Tu-95 turboprop is a product design during Soviet Union era of achieving more raw power than efficiency.

That does not explain the noise. You further revealed your technical ignorance. The Tu-95 is noisy because of its counter rotating props, not necessarily because of the turboprop itself.

Our WJ-6C turboprop is modern , 6 skew composite blade , low noise.

You can say it is 'low noise' all you want, but if it is noisier than the turbofan, do not complain if subs hears it.

Then may I ask you why USAF has been using P-3C for so many decades and only recently switch to P-8. If turboprop noise is really such a concern?

First...It is the US Navy that operates the P-3 Orion in anti-sub warfare.

Second...Just because we have been using does not mean we are not aware of its flaws. After all, the P-3 is a converted civilian airliner from the 1950s. We are moving to the P-8, a Boeing 737 variant, which offers improved performance in all areas. The P-3 is still useful, but it is approaching its limits.

Here...

http://www.defenseindustrydaily.com...unter-upgrading-britains-fleet-updated-02442/

Like Lockheed’s P-3 Orion, Britain’s Nimrod aircraft are also based on a previous airliner design. Unlike the USA, Britain chose a jet-age Comet airframe. They ended up with an aircraft that boasted an unrefueled endurance of over 10 hours and longer range than the P-3, but less-favorable “low and slow” flight characteristics. The British claim, however, that “propeller-engined aircraft make a discrete resonance that can be detected by submerged submarines, whereas the jet noise of the Nimrod is virtually undetectable.”

Anti-sub aircrafts do have to descent to lower altitude for variety of reasons. The subject of the turboprop's noise heard by subs have been presented on this forum before.

You are just making up things and try to confuse ordinary reader.

No, YOU are. And have been. Just like your fellow PDF Chinese, you refuse to acknowledged when you are proven wrong in the technical areas.

 

[Kyle Sun]

okay. .. our engine. tech. is. not. as. good as. usa. or Russia.

That's ok. We. chinese are not afraid of being inferior tech. level.

we. don't. complain about. it. but do our best to catch up. and. we. are. catching. up. quickly.

we. started from. scratch.
We were. not. even able. to. make a artillery in the. past.
And. thansk. to. our. great leader. maozedong.
We. never. wanted to. rely on. foreign country.

You. guys. should. seize the time. to mock. our engine or. something. else because it. will be very. hard for. you. to. find. a subject. to. show. off. before China.

Even you photo you added is old. The one I show is new and 6 blade. Who's lying. Posting some old photo trying to misled reader? Cheap shot!

You lied, as what you want to prove is that "China didn't get anything from Soviet AN-12 and applied to Made in China aircrafts Y-8, Y-9"
Even your latest Y9 or KJ200 is with 6 bladed, you can't negate the fact that China used Soviet AN-12 design on both Y-8, Y9 including the 4 blades in your first Y-8F 200 AWACS
And why 6 bladed ? because China start using Pratt and Whitney PW150B turboprop on KJ-200

So again, what I lied ?

FOR: PRATT & WHITNEY CANADA

NOVEMBER 6, 2002 - 12:50 EST

Pratt & Whitney Canada's PW150B Engine Selected for
China's Y8F600 Aircraft

ZHUHAI, CHINA--China Aviation Industry Corporation II (AVIC II)
and Pratt & Whitney Canada (P&WC) announced today that they have
signed agreement for the installation of the PW150B engine on the
Y8F600 aircraft program. The aircraft development program has
been launched and aircraft certification is scheduled for the
fourth quarter of 2005.

The Y8 is a four-engine medium transport aircraft developed and
manufactured by Shaanxi Aircraft Company, a subsidiary of AVIC
II. It has a maximum take-off weight of 61 tonnes and maximum
payload of 20 tonnes. The Y-8 series includes 16 successfully
developed versions, with a total of 90 aircraft produced and
sold. It is mainly used in general transport and postal aviation.

AVIC II has chosen the PW150B in their strategy to widen the Y-8
market, further improve operational performance and reduce direct
operating costs. The PW150B engine will power AVIC II's new
Y8F600 model. The PW150 is a latest-technology engine developed
based on the PW100 engine family's 74 million hours of flight
experience.

Fitted with the PW150B, Y8F600 will offer improved take-off
performance at "hot and high" airports and high altitude cruise
performance, extended engine service lives, and lower engine
operating and maintenance costs. In addition, noise levels will
be reduced and meet stringent airport noise restrictions. The
Y8F600 will also be fitted with modern industry standard civil
cargo handling systems. With aircraft MTOW increased to 65
tonnes, the Y-8F600 will have broad market appeal and sales of
more than 100 aircraft is expected.

"AVIC II has already established good cooperation with P&WC. I
hope that both parties will attain further success through theY8
re-engine program," said Dr. Zhang Yanzhong, President of AVIC
II.

Y-8F600 uses PW150B turboprop engines

Description: The Yun-8 or Y-8 is a turboprop-powered transport aircraft derived from the Antonov An-12 introduced by the Soviet Union in the late 1950s. The People's Liberation Army Air Force (PLAAF) received its first Y-8 transport aircraft in 1981. The Y-8A is a special version intended to airlift S-70C helicopters introduced in 1985. The Y-8C is a version developed with technical assistance from Lockheed Martin and featuring a pressurized cabin to fly at higher altitudes. The Y-8D is the export version of Y-8 military transport aircraft. The Y-8E is a version intended to serve as an airborne launch platform for unmanned aircraft. The Y-8F is a commercial freighter introduced in 1993. The Y-8H is an aerial surveillance variant. The Y8F100 freighter is fitted with improved avionics. The Y8F200 freighter is a modified Y-8C introduced in 1997. Overall, China has produced 100-120 Y-8s between 1981 and 2010.
The Y8F600 commercial freighter first flew on January 14, 2005 and was awarded type certification in 2006. It has been developed by Shaanxi Aircraft Company (SAC) with technical assistance from Antonov of Ukraine and Pratt & Whitney Canada which supplied the PW150B turboprop engines each developing more than 5,000-hp of power at takeoff. Both companies joined the project in 2002. In addition to the new engines, the aircraft also incorporates Western avionics, a two-man cockpit and an all-composite six-blade R408 propeller developed by Dowty company. The cargo handling system allows loading and unloading operations in just 30 minutes. The Y8F600 maximum takeoff weight is 65 tons and carries a maximum payload of 20 tons inside its specious cargo compartment. Besides, it is faster than previous Y-8 models thanks to the new engines and propellers and can travel over ranges between 1,700 kilometers with maximum payload to 4,800 kilometers in ferry flight conditions.
The People's Liberation Army Air Force (PLAAF) has chosen the Y8F600 as the platform for the KJ200 airborne early warning aircraft as well as other applications such as Electronic Intelligence (ELINT), maritime patrol and Electronic Warfare (EW) aircraft. In 2007, AVIC International and Antonov signed an agreement of partnership in future improvements to the Y8F600 airplane. In 2007, SAC was already working on a new generation Y-8 military transport aircraft called the Y-8X, also known as the Y-9, on the basis of the Y8F600 freighter. The Y-8X would have a maximum takeoff weight of 81 tons carrying a maximum payload between 25-30 tons. Flying at 9,000 meters of altitude with a cruise speed of 650 kilometers per hour it would be able to travel 7,800 kilometers. The program status remains uncertain but was intended to surpass the United States Air Force C-130J and compete with the Antonov An-70 and Airbus Military A400M transport aircraft.

100% everything made in China.

No, everything made in China y-9.

As proven of our AG600 amphibious. The engine used is WJ-6C turboprop. That is why the foreign company or countries can't do anything about it.

You are a bad liar!

 

[BoQ77]

I wish, you guys didn't blame Japan is bad at making aircrafts.
They are bad, but they build turbofan transport, MPA aircrafts, fighters at ease for decades.
You are great, but after decades of copying ancient An-12 airframe with 4 bladed turboprop, at last you can't make yourself a better one, but choose PW150B 6 bladed turboprop for your modernized An-12. Confirmed by AVIC

Never comfirm by AVIC. You are using some bogus western source and claimed as AVIC. AVIC claimed Y-9 is a complete design and so as the turboprop WJ-6C of 6 skew composite blades.

Don't put words into others mouth. You are despicable!
