pepin1234 Posted June 26, 2021 Share Posted June 26, 2021 In real life this J-11 have the same engines from Su-27S or it is a downgraded export version engine? [sIGPIC][/sIGPIC] Link to comment Share on other sites More sharing options...
GumidekCZ Posted September 23, 2021 Share Posted September 23, 2021 Searching for any doc about it, but in mean time found this in J-11A.Lua script: thrust_sum_max = 15200, -- J-11A 51.2 kN thrust_sum_ab = 25000, -- J-11A 84.6 kN Why the devs put note there with only 1/3 of thrust - assuming been meaned for single engine. Did the J-11A version used weaker export version of engines, or some kind of Chineese weak copy? The values suits to Klimov RD-93 turbofan engines. Weird thing is that same values at note was found at JF-17.Lua script, that plane is using RD-93 engines. - But AI unit have wrong thrust values for AI JF-17 - I made Bug report about it: Link to comment Share on other sites More sharing options...
GumidekCZ Posted September 23, 2021 Share Posted September 23, 2021 https://military.wikia.org/wiki/Shenyang_J-11 Russian AL-31F: https://military.wikia.org/wiki/Saturn_AL-31 AL-31F wet thrust 123 kN Chinese WS-10A: https://en.wikipedia.org/wiki/Shenyang_WS-10 Development: A full-scale WS-10A engine was first seen at the 2008 China International Aviation & Aerospace Exhibition. In 2009, Western media claim that the WS-10A approached the performance of the AL-31, but took much longer than the AL-31 to develop thrust. Furthermore, the engine reportedly only generated 110–125 kilonewtons (25,000–28,000 lbf) of thrust. In April 2009, Lin Zuoming, head of AVIC, reported that the engine's quality was unsatisfactory. In 2010, it was reported that reliability was also poor; the WS-10A lasted only 30 hours, while the AL-31 needed refurbishing after 400 hours. The quality problems encountered with the WS-10A reflected the state of the Chinese aerospace industry. AVIC initiated a general effort to improve quality control throughout its production chain in 2011. The WS-10A reportedly matured enough after 2009 to power the J-11B Block 02 aircraft.

LJQCN101 Posted September 23, 2021 Share Posted September 23, 2021 The A version of J-11 family has the same engine as Su-27S. The note of thrust_sum_max and thrust_sum_ab has no meaningful implications. EFM / FCS developer, Deka Ironwork Simulations. Link to comment Share on other sites More sharing options...
