CAN SOME ONE PROVIDE INFO ON THE AUTHENCITY OF THIS NEWS REPORT. Its dated Dec 31, but I have seen same report before.
NOTE: I have added some conversion of the # (1kN = ~224.5 lbs)
Thanks
"The owlet dragon" the engine domestic product work close completes (chart)
Center net information center time: 2006-12-31 11:38:47 origin: Chinese aviation newspaper
"The owlet dragon" at present uses is Russia makes RD33 the advanced version RD93 turbo fan engine.
According to the aviation newspaper reported that, the red lake machine shop in 2005 comprehensively starts the WS13 project the core machine and the entire machine development duty, impels the factory by the production 涡spurting engine to the production 涡fan engine transformation.
Of a ring-like flame tube WS13 core machine key components needs in the cavity Carries on the high temperature ceramics processing, this kind of ceramics are never has used the new material. Facing the challenge, red lake factory 6 workshops crafts room Director concurrently ceramic manager labor entertainer existing writing Wei Yongtiao the heavy burden, passes through consults the material in every way and independently designs the craft parameter, has finally successfully completed the high temperature flame tube ceramic processing. The result indicated that, the product material object each technical specification and the outward appearance quality had all achieved the prototypical standard, the individual target has also surpassed the prototypical standard.
But as early as in 2003, crucial FC-1 power domestic product Chemical industryDid already starts. A China National Aviation Corp group announced that, the Guizhou aircraft engine research institute coordinates FC-1 the development work, has carried out the turbo-fan engine essential engineering research and work and so on new turbo-fan engine design chart, pulled open Lebanon to be positiveCompanyThe turbo-fan engine develops prologue.
FC-1Domestic productMelted engine - WS-13 (the RD-33 domestically produced advanced version) already to carry on for 3 years. Should start the aircraft commander 4.14 meters, biggest outside diameter 1.02 meters, payment operating weight 1,135 kilograms. Thrust ratio 7.8, thrust augmentation thrust force 86.37000 kN (19,391 lbs), oil consumption 2.02 kilograms/ten cows hours. Biggest condition middle thrust force 56.75000 (12,749 lbs) kN, oil consumption 0.73/ ten cows hours. Cruise thrust 51.2000 kN(11,494 lbs), oil consumption 0.65/ ten cows hours. 进气量 80 kilograms/seconds, a bypass ratio 0.57, in front of the turbine wheel temperature 1650K, the total pressure compares 23. The MTBO is separated for 810 hours, the total life is 2,200 hours. (The editor pours: This engine overhaul gap and the total service life target by far surmounted the RD33 engine)
The WS-13 prototype Russia makes the RD33 涡fan engine.
This engine uses three levels of axes to flow the type width string solid titanium Alloy fan blade, after the two-pole electro-chemical treatment overall leaf plate structure, in front of the ventilator has the computer to control 可变弯度 the stator vane, expands the ventilator steady work scope. 8 levels of axes flow the type high pressure air compressor (first three levels for to be possible to adjust stator vane) the single stage low pressure turbine to use the hollow air cooled rotor blade, the single stage high pressure turbine for the unit crystal turbine blade and the stator blade, the annular chamber combustor, has the tip clearance control the air heat interchanger, synthesizes the digital authority control system. The gear box and the appendix are located the engine underneath, the performance advanced miniature turbine wheel auxiliary power unit.
The WS-13 majority of spare parts may use RD-33, partial only must slightly improve, small are partial is the new development. 外廓尺 inch close, after introduced the improvement RD-33 majority of productions process unit to carry on the technological transformations to a WP-13 production line, the Russia side is responsible to train the technical personnel and the partial workers, trained one group of workers to link the equipment to ship back together, installs the debugging to carry on the production, reasonably arranged various parts production progress, alternately parallel carried on. By Chinese and Russian both sides in the RD-33 design foundation, will carry on the improvement to the partial structural design, WS-13 is named as "Tianshan -21". (C001)
