Reports of improved jet engines in China and development for a mach 5 test plane faster than the SR71 Blackbird

August 27, 2015

An Aug. 25 report in Beijing-based newspaper China Aviation News praised the engine division of Xi'an-based aeronautic and aerospace firm AVIC Qingan Group. The report mentions a planned project which would see the development of China's first domestically-made turbofan-ramjet combined cycle engine, designed for an unnamed aircraft. The description of this engine suggests something resembling the Pratt and Whitney J58 variable cycle engine used by the SR-71 Blackbird.

A source close to the PLA Air Force was cited by New Outlook as stating that this is part of a project to develop a manned supersonic aircraft, currently in the preparation stages at a domestic research institute. The aircraft is expected to have a top speed faster than the Blackbird on completion, according to the source, although the project is yet to be formally launched.

The China Aviation News report stated that in the first half of 2015, the engine division of AVIC Qingan Group finished the design process for three engine products and gained approval for them in May and July.

The article went on to list descriptions of the three engines as China's first domestically developed turbofan-ramjet combined cycle engine designed for an unnamed aircraft, a classic model engine and a classic model engine with a medium bypass ratio. This suggests the latter two are improved versions of the WS-10 and WS-18 turbofan engines.

The turbofan-ramjet combined cycle engine project, however, has never before been made public. The article stated that there is no precedent for the project and that China currently has no suitable heat-resistant materials for the project and therefore will have to contract overseas suppliers, adding that without the appropriate tools, they will have to go about making them from scratch.

A PLA Air Force source told New Outlook that the aircraft that will use this engine has been in experimental development for several years by an aircraft institute in the southwest. The aim of the project is to surpass the SR-71 Blackbird with a plane that can reach speeds of almost five-times the speed of sound, which is the upper limit of a ramjet engine. For higher speeds, a supersonic combusting ramjet (scramjet) engine is necessary. The aircraft is said to be a large manned plane, with a similar design to Mikoyan's mysterious Project 301 hypersonic aircraft.

mach 5 nice but ws-10 still not in production.

mach 5 nice but ws-10 still not in production.

Close to 500 WS-10s are in use。

 

[Maarkhoor]

Close to 500 WS-10s are in use。

Then why not JF-17 equipped with that even J-10 is also using Russian engine.

 

[cirr]

Then why not JF-17 equipped with that even J-10 is also using Russian engine.

The JF-17 simply isn't designed for use with WS-10。

China bought batches of Russian engines for the J-10 over the years。There are still quite a few of the engines left in stock，which needs be exhausted first。

Anyhow J-11B、J-11BS、J-16、J-15S and J-11D all have WS-10 and variants，with J-10B and J-15 using same soon。

i think you meant ws 13

 

[nForce]

kidhar jaayega baba.. mach 5 leke... itni choti si toh duniya hai...Don't we have enough things to kill each other already ?

 

[CAPRICORN-88]

mach 5 nice but ws-10 still not in production.

I suggest some of you in here update yourself with the latest information before humiliating and posting irrelevant single-liner in here.

Then why not JF-17 equipped with that even J-10 is also using Russian engine.

Hahaha

This may the engine for the China's 6G fighter program.

There is may also another reason. WS10 is still not very stable, that's why can't be used for single engine plane. But very many 2 engines planes are useing it to improve the design and quality.

Not based on what i am reading. IMO there is NO stability issue with the WS-10 series engine today. Not one jetfighter equipped with the WS-10A has crashed so far.

I think the problem lies more with mass manufacturing the engines. There are just not enough of trained skilled machinists for the job unlike a mature engine making nation like Russia.

FYI WS-10A engine can't fitted into a JF-17 fuselage for one. Next the entire plane needs to be redesign for the task.

The new JF-17 will probably be equipped with a China own WS-13 engine instead. But since they have ordered so many RD-93, the stock have to be utilised first for economic reason.


On the 17 June 2015, at the Paris Airshow, a senior Chinese aviation official has revealed that the Chengdu Aircraft Corporation FC-1/JF-17 fighter co-developed with Pakistan has been test-flown with a new Chinese MEDIUM-THRUST turbofan engine.

Li Yuhai, an executive vice president with the Aviation Industries Corporation of China (AVIC), told IHS Jane's at the Paris Airshow that a new Chinese turbofan for the J-17 has been "under testing," has completed "lab tests", and that "flight testing is in progress". He also said that the new engine would have a thrust SLIGHTLY GREATER than the 8.7-ton thrust of the JF-17's current Klimov RD-93 turbofan.

At a joint Sino-Pakistani press conference on 15 June, Li also said progress was being made on the twin-seat version of the JF 17.

Pakistani sources at Paris confirmed that a JF-17 has been flying with the new Chinese turbofan, which could be revealed publicly "very soon". There is a suggestion the engine could be named 'WS-17' to complement the JF-17b, but officials did not provide any further performance indicators.

Answer to the upcoming SR-72 ?

Most likely.
Meet the SR-72 · Lockheed Martin

Envisioned as an unmanned aircraft, the SR-72 would fly at speeds up to Mach 6, or six times the speed of sound. At this speed, the aircraft would be so fast, an adversary would have no time to react or hide.

“Hypersonic aircraft, coupled with hypersonic missiles, could penetrate denied airspace and strike at nearly any location across a continent in less than an hour,” said Brad Leland, Lockheed Martin program manager, Hypersonics. “Speed is the next aviation advancement to counter emerging threats in the next several decades. The technology would be a game-changer in theater, similar to how stealth is changing the battlespace today.”

Hypersonic Research and DevelopmentSR-72 is not the first hypersonic Skunk Works® aircraft. In partnership with the Defense Advanced Research Projects Agency, engineers developed the rocket-launched Falcon Hypersonic Technology Vehicle 2 (HTV-2). The HTV-2 research and development project was designed to collect data on three technical challenges of hypersonic flight: aerodynamics; aerothermal effects; and guidance, navigation and control.


The SR-72’s design incorporates lessons learned from the HTV-2, which flew to a top speed of Mach 20, or 13,000 mph, with a surface temperature of 3500°F.

A hypersonic aircraft will be a game changer.
