i was going to talk about this..So is WS-35 the 25tf class engine that Shenyang is working on or a separate development? Since WS-35 is apparently a Xi'an product.
AECC Shenyang has sperate program that is ongoing for years and Shenyang will not stop on WS-25.. they have big plans.
WS-35 just announced by Xian. so this could be next gen ACE engine or maybe 30+ tons class HBR engine. we should wait for more information about WS-35.
